Autores: M.M. Silva,Germana; Bezerra,Raquel P; Teixeira,José A; Porto,Tatiana S; Lima-Filho,José L; Porto,Ana Lúcia F.
Background Streptomyces sp. DPUA 1576 from Amazon lichens was studied to protease and fibrinolytic production. A 2² factorial experimental design was applied to optimize its protease enzyme production using two independent variables, namely soybean flour and glucose concentrations. Results The optimal conditions to obtain high protease production (83.42 U/mL) were 1.26% soybean flour and 1.23% glucose concentration. A polynomial model was fitted to correlate the relationship between the two variables and protease activity. In relation to fibrinolytic activity, the highest activity of 706.5 mm² was obtained at 1.7% soybean flour and 1.0% glucose concentration, which was 33% higher than plasmin. Fibrinolytic production was not optimized in the studied...

Production and stability studies of the bioemulsifier obtained from a new strain of Candida glabrata UCP 1002
Provedor de dados: 69
Autores: Asfora Sarubbo,Leonie; Moura de Luna,Juliana; de Campos-Takaki,Galba Maria.
Evaluation of both tenso-active and emulsifying activities indicated that a biosurfactant was produced by the newly isolated and promising strain Candida glabrata isolated from mangrove sediments. The extracellular water-soluble emulsifying agent was isolated and identified as a heteropolymer. The maximum of bioemulsifier production was observed when the strain was grown on soluble and insoluble substrates cotton seed oil plus glucose, reaching values of 10.0 g/l after 144 hrs at 200 rpm. The cell-free culture broth containing the examined agent lowered the surface tension of the medium to 31 mN/m. Stable and compact emulsions with emulsifying activity of 75% of cotton seed oil were detected. The emulsification capacity remained practically unaltered...

Особенности реорганизации тканевого метаболизма у двустворчатого моллюска Anadara inaequivalvis (Bruguiere, 1789) в условиях экспериментального голодания
Provedor de dados: 13
Autores: Солдатов, А. А.; Андреенко, Т. И.; Головина, И. В.
В экспериментальных условиях исследовано влияние голодания на направленность метаболических процессов в тканях двустворчатого моллюска-вселенца Anadara inaequivalvis (Bruguiere, 1789). Длительность эксперимента – 18 сут. Показано, что на начальных этапах голодания (6 сут.) анадара использует ресурс тканевого лактата в направлении реакций окислительного декарбоксилирования. Об этом свидетельствует значительный рост активности лактатдегидрогеназы на фоне снижения содержания лактата и повышения уровня пирувата в тканях. Процесс адаптации анадары к голоданию идет по пути использования резерва аминокислот в процессах биосинтеза белка. Это отражает уменьшение уровня аминного азота во всех исследованных тканях и рост содержания белка при отсутствии выраженных...

Effect of diets containing different levels of highly unsaturated fatty acids on physiological and immune responses in Pacific whiteleg shrimp Litopenaeus vannamei (Boone) exposed to handling stress
Provedor de dados: 5
Autores: Mercier, Laurence; Racotta, Ilie; Yepiz-plascencia, Gloria; Muhlia-almazan, Adriana; Civera, Roberto; Quinones-arreola, Marcos F.; Wille, Mathieu; Sorgeloos, Patrick; Palacios, Elena.
Juveniles fed a diet containing a low or a high level of highly unsaturated fatty acids (HUFA) for 38 days were exposed to handling stress. In a first experiment, stress was applied daily for 30 days, after which the physiological and immunological variables were measured, whereas in a second experiment, stress was applied once and samples were obtained 1 and 24 h after the stressor event. Shrimp that were stressed for 30 days showed significantly lower survival, final weight and feed consumption compared with unstressed shrimp. The concentration of the high-density lipoprotein beta-glucan-binding protein was significantly higher in shrimp fed the high-HUFA diet. The glucose concentration in the haemolymph was significantly higher in long-term stressed...

Hepatic phosphoenolpyruvate carboxykinase gene expression is not repressed by dietary carbohydrates in rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 5
Autores: Panserat, Stéphane; Plagnes Juan, E; Breque, Jeanine; Kaushik, Sadasivam.
Phosphoenolpyruvate carboxykinase (PEPCK) is a rate-limiting enzyme in hepatic gluconeogenesis and therefore plays a central role in glucose homeostasis. The aim of this study was to analyse the nutritional regulation of PEPCK gene expression in rainbow trout (Oncorhynchus mykiss), which are known to use dietary carbohydrates poorly. A full-length hepatic PEPCK cDNA (2637 base pairs with one open reading frame putatively encoding a 635-residue protein) was cloned and found to be highly homologous to mammalian PEPCKs. The presence of a putative peptide signal specific to a mitochondrial-type PEPCK in the deduced amino acid sequence suggests that this PEPCK gene codes for a mitochondrial form, In gluconeogenic tissues such as liver, kidney and intestine,...

Quelques aspects de la regulation du systeme neuroendocrine produisant la CHH et de la relation entre le rythme circadien et la glycemie
Provedor de dados: 5
Autores: Kallen, J.
In crayfish, the hemolymph glucose level shows an endogenous circadian rhythmicity which is expressed by a nocturnal glucose rise. This study shows that injections of serotonin and dopamine result in hyperglycemia and that injections of met-enkephalin decrease hemolymph glucose level as well as the nocturnal circadian glucose peak. Using immunocytochemistry, these neurotransmitters have been located in the eyestalk and their relationship with the CHH cell system is described.

Provedor de dados: 5
Autores: Enes, P; Panserat, S; Kaushik, Sadasivam; Oliva Teles, A.
A study was conducted to evaluate the effect of two dietary carbohydrate sources (waxy maize starch and glucose) on the metabolic adaptation of sea bass juveniles (initial weight: 24 g) to a heat shock treatment (temperature rise from 18 degrees C to 25 degrees C within 24 h). Two isonitrogenous and isolipidic diets were fon-nulated to contain 20% waxy maize starch (WS diet) or 20% glucose (GLU diet). Triplicate groups of fish were fed to near satiation for 4 weeks at both temperatures (18 degrees C and 25 degrees C). Then, fish previously maintained at 18 degrees C were submitted to a heat shock (18 degrees C to 25 degrees C) and continued to be fed with the same diets during I more week. The higher water temperature significantly improved growth...

Autores: Hanquet, Anne-caroline.
In the Pacific oyster, Crassostrea gigas, the energy necessary for general metabolism and gametogenesis is mainly provided by the glycogen stored in the vesicular cells. The first level of glycogen metabolism control is the entrance of glucose into cells. The monitoring of the uptake capacity of [U-14C] D-glucose revealed the existence of a saturable component with kinetic constants: Km = 0.71 mM ; Vmax = 0.22 nmol/h/106cells. The use of inhibitors has revealed the presence of carriers belonged to GLuT and SGLT types. A follow-up showed a seasonal variation of the uptake capacity and incorporation of glucose into glycogen, and a high expression of SGLT during mobilization of glycogen and gametes maturation. A bioassay in a controlled rearing system has...

Effects of environmental conditions on the sessile existence of an estuarine sediment bacterium.
Provedor de dados: 5
Autores: Geesey, G; Salas, S; Mittelman, M.
A submerged glass coverslip technique was developed to determine dissolved organic nutrient uptake by adherent cells of a sediment isolate of Enterobacter cloacae . Cells which colonized the coverslips in swirling culture flasks during anaerobic growth remained firmly attached during manipulations employed to determine uptake of radiolabeled glucose by the adherent population. The attached cells were capable of a more rapid rate of glucose uptake than free cells. Lineweaver-Burk plots demonstrated different glucose uptake kinetics for the 2 cell populations. The data suggest that physiological changes occur in cells soon after they become attached to surfaces. These changes appear to enhance the metabolic activity of the adherent population.

ABSTRACT The aim of this study was to evaluate if Lippia alba has different chemotypes according to the chemical composition of the essential oil (EO) considering collection site, and if the EO may have different effects on blood and plasma parameters in silver catfish, Rhamdia quelen, during and immediately after anesthesia. The citral (EO-C) and linalool (EO-L) chemotypes were identified, and both presented similar anesthetic effects for silver catfish. Fish were exposed to two concentrations of each EO, which induced slow and fast anesthesia (100 and 300 µL L-1, respectively). Blood ions did not change at any time of anesthesia induction and recovery and, therefore, the electrolyte balance was not altered. Blood gases oscillated through all exposure and...

A simple and clear means to identify the physiological status of follicles is essential for study of follicular biology. In the present study, we verified a novel classification procedure based on analysis of the follicular population and glucose concentration in follicular fluid (FF) as an alternative method to classify bovine follicles. Paired ovaries were collected from heifers, and the number of follicles and stage of the CL were recorded. Follicles were initially divided into the following 3 groups according to diameter and the ratio of E2 and P4 (E/P): E2 active (E-A: E/P≥1), E2 inactive (E-I: E/P&lt;1, ≥8.5 mm) and small follicles (E/P&lt;1, &lt;8.5 mm). E-A follicles were easily identified as E2-rich dominant follicles and were further classified...

The objective of this work was to evaluate the growth and the stress levels of juvenile dourado (Salminus brasiliensis) cultivated in cages. Fish stocked at densities of 15 (D15) and 30 (D30) fish per square meter were evaluated in a completely randomized design with three replicates. Fish were fed twice a day with extruded ration (42% crude protein). Density influenced only biomass and daily food intake, and glucose and lactate concentrations increased over time. D15 and D30 did not influence the growth of dourado. However, the increase of glucose and lactate levels over time indicates that cultivation in cages is a stressful condition for this species.

Blood metabolites as predictors to evaluate the body condition of Neopelma pallescens (Passeriformes: Pipridae) in northeastern Brazil
Provedor de dados: 103
Autores: Azeredo,Luane M.M.; Oliveira,Talita C.; Lopez,Luiz C.S.
ABSTRACT Body condition is an important ecological attribute that can provide a measure of the energy stored by an animal or population. Body condition is traditionally ascertained with morphometric body condition indices (BCIs), but some researchers have used various physiological and biochemical parameters as predictors of body condition. This study aimed to test reliable biochemical predictors of body condition in individuals of Neopelma pallescens (Lafresnaye, 1853), found in an Atlantic forest patch. For this purpose we examined the relationship between body condition and the concentrations of blood glucose and ketones. We also verified correlations between blood metabolite concentrations and ecological variables, including time of day, seasons,...

Linking dietary energy and skeletal development in the horse
Provedor de dados: 96
Autores: Staniar,William Burton.
Athletic production is what is sought from the horse. As mammary development is important to the dairy cow, skeletal development is important to horses meeting their production goals. As any integrative physiologist will appreciate, the variables that come together to result in optimal skeletal development are complex. Nutrition is one of these, and it contains two broad variables; the supply of dietary nutrients and energy. This presentation will focus on dietary energy and its links with skeletal development. I propose that it is not simply the amount of dietary energy, but the way and from that that energy is supplied that impacts skeletal development. Through an understanding of how dietary energy impact skeletal development, more precise feeding...

Carbohydrate metabolism and metabolic disorders in horses
Provedor de dados: 96
Autores: Hoffman,Rhonda M.
Horses evolved consuming primarily fermentable forage carbohydrates, but forage diets have been traditionally supplemented with grain meals rich in starch and sugar in order to provide additional calories, protein and micronutrients. Starch and sugar are important for performance horses, but the consumption starch-rich meals may cause equine digestive and metabolic disorders. The critical capacity for preileal starch digestibility appears to be 0.35 to 0.4% but may be as little, depending on the source of starch. Small intestinal absorption of simple sugars is limited by the activity and expression of two classes of glucose carrier proteins, which are affected by chronic intake of hydrolyzable carbohydrate but may be sluggish to respond to abrupt changes...

This study examined the stress response of pirarucu juveniles in a closed system transport. Pirarucu (Arapaima gigas) is a native Amazonian fish species from the Osteoglossidae family and an obligated air breather. A short duration transport trial (6h) was undertaken comparing closed polyethylene bags filled with atmospheric air (Air group) and bags filled with pure oxygen (Oxi group). Dissolved oxygen was the only water parameter that presented a difference between fish groups, and was saturated in the oxi group as expected. There was no mortality in either group after transport. Fish feeding was observed 36 h after transport for all fish, and normal feeding consumption was observed at 72 h. In both groups physiological responses were similar. Cortisol...

ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure better quality of the raw material. This study aimed to analyze the levels of soluble sugars during the maturation phase and assess the technological and productivity indexes of four irrigated sugarcane genotypes in the region of Rio Largo, Alagoas. The experiment was conducted in randomized blocks in a 4 x 2 x 5 factorial: four genotypes (RB92579, RB98710, RB99395 and RB961003), two stem portions...

ABSTRACT This study aims at evaluating the effects of electrolytes, glucose and cortisol levels over heart rate (HR) and heart rate variability (HRV) in healthy newborn calves. Seventeen healthy Holstein calves were evaluated during their first month of life, and the plasma concentrations of glucose, cortisol, calcium, magnesium, inorganic phosphorus, sodium and potassium were analyzed. HRV indexes were determined in the time and frequency domains through the analysis of neonatal electrocardiogram recordings. In the first day, low blood levels of phosphorus presented a strong correlation with the HR and the increased high-frequency components of HRV. The plasma concentrations of magnesium decreased significantly throughout the 35 days, revealing a positive...

Autores: Santos,André Luis Wendt dos; Silveira,Vanildo; Steiner,Neusa; Maraschin,Marcelo; Guerra,Miguel Pedro.
Embryogenic cultures of Araucaria angustifolia were established in a BM liquid medium supplemented with 2 µM 2,4-dichlorophenoxyacetic acid, 1 µM 6-benzylaminopurine and 1 µM kinetin (BM2) and in a BM medium free of growth regulators (BM0). During 42 days in culture, the cell growth pattern of both cultures was similar. The pH of the culture medium of both BM0 and BM2 underwent progressive reduction during culture time. For both the embryogenic cultures a preferential uptake of glucose in the late stages of cell growth kinetics was observed. The extracellular protein content was similar for both the embryogenic cultures. Acetocarmine and Evan's blue double stain showed major differences for early somatic embryo organisation, in which only the embryogenic...

Xylitol production by Candida parapsilosis under fed-batch culture
Provedor de dados: 52
Autores: Furlan,Sandra A.; Castro,Heizir F. de.
Xylitol production by Candida parapsilosis was investigated under fed-batch cultivation, using single (xylose) or mixed (xylose and glucose) sugars as substrates. The presence of glucose in the medium induced the production of ethanol as secondary metabolite and improved specific rates of growth, xylitol formation and substrate consumption. Fractionated supply of the feed medium at constant sugar concentration did not promote any increase on the productivity compared to the single batch cultivation.

The heat conduction microcalorimeter can be used to evaluate the metabolic rates of the sperm cell. Two ejaculates of four stallions were cooled to +5ºC and checked for sperm motility (bright field microscopy), viability (eosin 3%), functional membrane integrity (hyposmotic swelling test), and heat production (microcalorimetry). Glucose and sperm cell concentrations were determined in order to measure the heat outputs resulting from sperm metabolism. Sperm viability, membrane integrity and sperm motility did not differ among the different glucose concentrations tested. Nevertheless, the highest heat output detected by the microcalorimeter was obtained with 6 mM glucose and 10(8) spermatozoa/mL. Since conduction microcalorimetry offered additional...

Autores: Silva,Débora Danielle Virgínio da; Mancilha,Ismael Maciel de; Silva,Silvio Silvério da; Felipe,Maria das Graças de Almeida.
The effect of glucose on xylose-to-xylitol bioconversion by Candida guilliermondii was examined by adding it to sugarcane bagasse hydrolysate medium to obtain different glucose:xylose ratios (1:25, 1:12, 1:5 and 1:2.5). Under experimental conditions, increasing glucose:xylose ratio improved the assimilation of the xylose present in the hydrolysate by yeast, resulting in biomass increase, and in the formation of xylitol and glycerol/ethanol by-products. Maximum values of xylitol yield (0.59 g g-1) and volumetric productivity (0.53 g l-1.h-1) were obtained with glucose:xylose ratio of 1:5, resulting in the higher conversion efficiency (64.3%).

Several species of terrestrially hibernating frogs, turtles and insects have developed mechanisms, such as increased plasma glucose, anti-freeze proteins and antioxidant enzymes that resist to freezing, for survival at subzero temperatures. In the present study, we assessed the importance of glucose to cryoresistance of two anuran amphibians: the frog Rana catesbeiana and the toad Bufo paracnemis. Both animals were exposed to -2ºC for measurements of plasma glucose levels, liver and muscle glycogen content, haematocrit and red blood cell volume. Frogs survived cold exposure but toads did not. Blood glucose concentration increased from 40.35 ± 7.25 to 131.87 ± 20.72 mg/dl (P &lt; 0.01) when the frogs were transferred from 20 to -2ºC. Glucose accumulation in...

Glutamine and glutamate as vital metabolites
Provedor de dados: 56
Autores: Newsholme,P.; Lima,M.M.R.; Procopio,J.; Pithon-Curi,T.C.; Doi,S.Q.; Bazotte,R.B.; Curi,R.
Glucose is widely accepted as the primary nutrient for the maintenance and promotion of cell function. This metabolite leads to production of ATP, NADPH and precursors for the synthesis of macromolecules such as nucleic acids and phospholipids. We propose that, in addition to glucose, the 5-carbon amino acids glutamine and glutamate should be considered to be equally important for maintenance and promotion of cell function. The functions of glutamine/glutamate are many, i.e., they are substrates for protein synthesis, anabolic precursors for muscle growth, they regulate acid-base balance in the kidney, they are substrates for ureagenesis in the liver and for hepatic and renal gluconeogenesis, they act as an oxidative fuel for the intestine and cells of the...

Due to the presence of the renin-angiotensin system (RAS) in tissues and its specific influence on white adipose tissue, fat cells are possible targets of pharmacological RAS blockers commonly used as anti-hypertensive drugs. In the present study, we investigated the effects of different RAS blockers on fat cell metabolism, more specifically on lipolysis, lipogenesis and oxidation of energy substrates. Isolated primary adipocytes were incubated with different RAS blockers (aliskiren, captopril and losartan) in vitro for 24 h and lipolysis, lipogenesis and glucose oxidation capacities were determined in dose-response assays to a β-adrenergic agonist and to insulin. Although no change was found in lipolytic capacity, the RAS blockers modulated lipogenesis...

Our aim was to determine the profile of and the correlation between biochemical markers to be used to assess renal function and maturation of the fetus in the amniotic fluid during pregnancy and to determine the distribution of normal values for creatinine, N-acetyl-ß-D-glucosaminidase (NAG), ß2-microglobulin, glucose, urea, sodium, potassium, phosphorus, calcium, uric acid, albumin, and osmolality in three gestational age groups. This was a cross-section study that assessed 115 samples of amniotic fluid during three different periods of pregnancy, i.e., 13 to 20, 27...

Provedor de dados: 58
Autores: Erzinger,Gilmar Sidnei; Silveira,Mauricio Moura da; Costa,José Paulo Castilho Lopes da; Vitolo,Michele; Jonas,Rainer.
Previously grown cells of the ethanologenic bacterium Zymomonas mobilis produce sorbitol and gluconic acid, in reactions catalysed by the periplasmic enzymes glucose-fructose oxidoreductase (GFOR) and glucono-delta-lactonase (GL). The GFOR/GL system activity, in cells to be used in this bioconversion, depends on growth conditions. In batch runs, with initial glucose concentrations (S0) from 42 to 230 g/L, the highest specific and total GFOR/GL activities were obtained with S0 = 153 g/L (12.6 U/g cells and 62 U/L). Higher S0 led to decreasing activities in fresh cells. With S0 = 209 g/L, the final specific activity was only 7.0 U/g. After disruption of cells, however, an activity over 15 U/g was revealed. Since growth inhibition with S0 over 153 g/L was...

Provedor de dados: 58
Autores: Divakaran,Dibu; Chandran,Aswathi; Pratap Chandran,R.
Alpha amylase (α-1, 4-glucan-glucanhydrolase, EC 3.2.1.1), an extracellular enzyme, degrades α, 1-4 glucosidic linkages of starch and related substrates in an endo-fashion producing oligosaccharides including maltose, glucose and alpha limit dextrin (7). The present study deals with the production and comparative study of production of α-amylase from two strains of Bacillus licheniformis, MTCC 2617 and 2618, by using four different substrates, starch, rice, wheat and ragi powder as carbon source by submerged fermentation. The effect of varying pH and incubation temperature, activator, inhibitor, and substrate concentration was investigated on the activity of α-amylase produced by MTCC strain 2618. The results shows that the production of the α-amylase by...

Glycemic effects of simvastatin: Where do we stand?
Provedor de dados: 60
Autores: Razali,Nor Razida; Huri,Hasniza Zaman; Ibrahim,Luqman; Vethakkan,Shireene Ratna; Abdullah,Bashar Mudhaffar.
ABSTRACT In clinical practice, simvastatin is usually used in the treatment of dyslipidemia patients and those at risk of or with established cardiovascular disease. However, previous studies have shown that simvastatin has the potential to affect glycemic parameters as it reportedly reduced insulin secretion and sensitivity. The exact mechanism by which simvastatin affects glycemia is still unknown, but previous studies have postulated the involvement of the glucose-insulin secretion mechanism. This review focuses on the effects of simvastatin, either alone or in combination with other lipid lowering agents, antidiabetics and antihypertensives, on glucose homeostasis. Some studies have reported that simvastatin might impair the levels of glucose...

Gd-GLU toward NMR imaging: synthesis, characterization and breast cell uptake assay
Provedor de dados: 60
Autores: Campos,Tarcisio Passos Ribeiro de; Dalmazio,Ilza; Augusti,Rodiney; Almeida,Iassudara Garcia.
Breast cancer cell uptake of Gd-metal is investigated based on the formation of coordinate compounds of gadolinium and glucose (Glu) molecules in solution. The hypothesis is that glucose helps Gd-internalization by complex formations constituted of Gd3+ coordinate to m-glucose molecules, whose valence was complemented by Cl- anions. Such a proposal is an insight toward a metabolic-dependent contrast-agent for cancer and inflammation in magnetic resonance image. A solution was prepared based on anhydrous d-glucose and gadolinium chloride (Gd-Glu). Uptake assays for MDA-MB-231(c231) cells were elaborated collecting incubated c231-cells with Gd-Glu and measuring metal-uptake and their concentrations by Nuclear Activation Analysis (NAA). The ionic solution was...

Glycogen Determination in Bovine Muscle: A Proposal for Rapid Determination
Provedor de dados: 117
Autores: Hargreaves B,Antonio; Barrales V,Luis; Barrales Z,Daniela; Riveros F,José Luis; Peña R,Iván.
A practical, rapid and inexpensive method for muscle glucose determination is proposed. The method is based on acid digestion of the sample, followed by neutralization of the solution and the subsequent glucose determination using a domestic glucometer for human blood glucose level control. In a pre-experimental phase, the accuracy of this methodology and the titration method was determined, comparing results to pre-established glucose concentrations. There were significant differences between the glucose reading given by the glucometer and the pre-established glucose concentrations and the results given by the titration method. Nevertheless, when discrepancies (bias) were identified, differences resulted non-significant (P = 0.85). Subsequently, muscle...

ABSTRACT: This study aimed to examine the action of the essential oil of Lippia alba (EOLA) in the stress response for transport of Nile tilapia Oreochromis niloticus . The fish were transported into three treatments (in triplicate): control, 10 and 20 µL L-1 EOLA, with loading density of 15 fish/plastic bags for 8h. Plasma glucose levels were significantly decreased in fish exposed to 20µL L-1 EOLA in comparison with the control group and fish exposed to 10µL L-1 EOLA, but the plasma cortisol, lactate and paraoxonase levels were similar. Un-ionized ammonia and ventilatory rate demonstrated a significant reduction in the treatments with the use of EOLA. In conclusion the use of 20µL L-1 EOLA is indicated for Nile tilapia transport.

Autores: Sales,Thais Silva; Paiva,Patrícia Duarte Oliveira; Siqueira,Heloísa Helena de; Manfredini,Guilherme Mariano; Lima,Luiz Carlos de Oliveira.
ABSTRACT The knowledge of physiological and biochemical aspects occurring at the postharvest phase of flowers is critical to guide efficient conservation techniques for maintaining quality and longevity. Factors that cause deterioration of cut flowers after harvest are dehydration, low carbohydrate contents, the presence of microorganisms in vase solution or stem and late stage of development at harvest. Thus, the objective was to determine the effect of harvest stages of calla lily stems and storage solutions on water relations and contents of starch and sugars. Flower stems were harvested in the following opening stages of the spathe: early-stage (cartridge) and 1/3 open and were arranged in six storage solutions containing 1, 2, 4 and 6% glucose and the...

YACON INULIN LEACHING DURING HOT WATER BLANCHING
Provedor de dados: 64
Autores: Scher,Caroline Fenner; Brandelli,Adriano; Noreña,Caciano Zapata.
ABSTRACTYacon roots contain inulin, which has prebiotic properties and it may be used as sucrose or fat substitutes. However, inulin is very soluble in water. The loss of this important nutrient during blanching is caused mainly by diffusion or leaching, which might be diminished if blanching temperature - time conditions are correctly employed. The aim of this study was to determine the leaching of the sugars inulin, glucose and fructose, present in yacon roots, during hot water blanching under different time/temperature conditions. The samples were cleaned and peeled and cut into geometric forms of 1.75 ± 0.35 mm thick disks. A complete factorial experimental design was used, and the treatments of the samples were compared using the Tukey test. The...
