ANDRÉ, W. P. P.; PAIVA JUNIOR, J. R. de; CAVALCANTE, G. S.; RIBEIRO, W. L. C.; ARAÚJO FILHO, J. V. de; SANTOS, J. M. L. dos; ALVES, A. P. N. N.; MONTEIRO, J. P.; MORAIS, S. M. de; SILVA, I. N. G. da; OLIVEIRA, L. M. B. de; ABREU, F. O. M. da S.; BEVILAQUA, C. M. L..
Abstract: The objective of this study was to evaluate the efficacy of carvacryl acetate (CVA) and nanoencapsulated CVA (nCVA) on gastrointestinal nematodes of sheep. The CVA was nanoencapsulated with chitosan/gum arabic and the efficacy of nanoencapsulation (EE), yield, zeta potential, nanoparticle morphology and release kinetics at pH 3 and 8 were analyzed. Acute and subchronic toxicity were evaluated in rodents and reduction of egg counts in the faeces (FECRT) of sheep. The sheep were divided into four groups (n = 10): G1, 250 mg/kg CVA; G2, 250 mg/kg nCVA; G3, polymer matrix and G4: 2.5 mg/kg monepantel. EE and nCVA yield were 65% and 57%, respectively. The morphology of the nanoparticles was spherical, size (810.6±286.7 nm), zeta potential in pH 3.2...

Characteristics of freeze-dried nanoencapsulated fish oil with whey protein concentrate and gum arabic as wall materials Ciênc. Tecnol. Aliment.
VAHIDMOGHADAM,Farideh; POURAHMAD,Rezvan; MORTAZAVI,Ali; DAVOODI,Daryoush; AZIZINEZHAD,Reza.
Abstract Fish oil has many health effects, but due to its strong odor and rapid spoilage, its use in food formulations is limited. For these reasons, nanoencapsulation of fish oil can be important. The purpose of this study was to investigate the influence of whey protein concentrate (WPC) and gum arabic as wall materials on the characteristics of nanoencapsulated fish oil powder. Gum arabic and WPC were used in varying amounts for nanoencapsulation of fish oil. An oil-in-water emulsion with 6% fish oil and 20% aqueous solution of wall materials was prepared by sonication (24 kHz for 120 sec). The diameter of the emulsion droplets was measured by particle size analysis and they then were dried in a freeze-drier. The results showed that the type and...

Economic Incentives for Entry and Exit in Gum Arabic Agroforestry System in Sudan AgEcon
Rahim, Afaf H.; van Ierland, Ekko C.; Wesseler, Justus.
The gum tree (Acacia senegal) in the Sahel-Sudan zone has many environmental benign functions. An important function is to control desertification. In this paper we analyze farmers' economic incentives to preserve the existing gum trees and their incentives to create new plantations using a real options approach. Results indicate that agricultural crops provide higher economic benefits as compared to gum agroforestry system. However, on the one hand, as gum arabic is produced during the dry period and land is abundant, there are low incentives for deforestation. Instead, farmers' tend to leave the land idle and let the tree growing. On the other hand, our results suggest that an increase in the prices of gum arabic of about 330 per cent is needed to induce...

Encapsulation of lycopene using spray-drying and molecular inclusion processes BABT
Nunes,Itaciara Larroza; Mercadante,Adriana Zerlotti.
This study aimed to obtain encapsulated lycopene in a powder form, using either spray-drying or molecular inclusion with beta -cyclodextrin ( beta -CD) followed by freeze-drying. The encapsulation efficiency using spray-drying ranged from 94 to 96%, with an average yield of 51%, with microcapsules showing superficial indentations and lack of cracks and breakages. Lycopene- beta -CD complexes were only formed at a molar ratio of 1:4, and irregular structures of different sizes that eventually formed aggregates, similar to those of beta -CD, were observed after freeze-drying. About 50% of the initial lycopene did not form complexes with beta -CD. Lycopene purity increased from 96.4 to 98.1% after spray-drying, whereas lycopene purity decreased from 97.7 to...

Encapsulation of Red Cabbage (Brassica oleracea L. var.capitata L. f. rubra) Anthocyanins by Spray Drying using Different Encapsulating Agents BABT
Bernstein,Anahi; Noreña,Caciano Pelayo Zapata.
ABSTRACT This study aimed to evaluate the influence of the drying air temperature (140 and 160°C) and the concentration of encapsulating agents gum Arabic and polydextrose (10 and 15%) on the physicochemical characteristics of the red cabbage extract obtained through extraction in acidulated water and drying using a spray dryer. The anthocyanin retention, antioxidant activity, water activity, solubility, color and microstructure of the final product were analyzed. Results showed that increase in the temperature did not cause significant changes in the anthocyanin quantity and antioxidant activity. The microscopic analysis revealed that for both the encapsulating agents, the absence of fissures and porosity in the particle surfaces produced powder with high...

Gum arabic production and marketing in Senegal: interlocked transactions and supply chain implications AgEcon
Mujawamariya, Gaudiose; D'Haese, Marijke F.C..
Interlocked relationships are characterised by traders’ supply of inputs and cash to producers on credit, to be reimbursed at sale time based on pre-defined prices which are often lower than the prevailing market price. The study analyses determinants of choice for interlocking in the gum arabic sector in Senegal and the effect of interlocking on gum production and market participation; gum arabic is a natural exudates of Acacia Senegal trees that grow in the semi-arid lands of Africa. Data from 422 gum producers in Northern and Eastern regions of Senegal are used. About 45percent of respondents are involved into interlocking with village shop-owners or mobile traders. Interlocking has a negative effect on prices received by gum collectors. However, in the...

Microencapsulation of maqui (Aristotelia chilensis Molina Stuntz) leaf extracts to preserve and control antioxidant properties Chilean J. Agric. Res.
Vidal J,Leslie; Avello L,Marcia; Loyola C,Cristina; Campos P,Jorge; Aqueveque M,Pedro; R. Dungan,Stephanie; Galotto L,Maria; Guarda M,Abel.
Microencapsulation technology is an alternative to stabilize stress factors and protect food ingredients or additives, which include environmentally sensitive bioactive principles in protective matrices to increase their functionality and life span. The objective of this research was to study conditions to obtain microcapsules with antioxidant capacity from a maqui (Aristotelia chilensis [Molina] Stuntz, Elaeocarpaceae) leaf extract by emulsification and subsequent retention after microencapsulation. Microcapsules were produced by water-in-oil emulsion (W/O) using a phase of the aqueous maqui leaf extract and gum arabic, and a liquid vaseline phase. Maqui leaf extract antioxidant capacity was 99.66% compared with the aqueous phase of the emulsion at 94.38...

Water adsorption isotherms and isosteric sorption heat of spray-dried and freeze-dried dehydrated passion fruit pulp with additives and skimmed milk Ciência e Agrotecnologia
Catelam,Kelly Tafari; Trindade,Carmen Sílvia Fávaro; Romero,Javier Telis.
Moisture equilibrium data of passion fruit pulp powders with maltodextrin and gum arabic were obtained by two different drying methods (spray drying and freeze drying) and determined at 20, 30, 40 and 50º C. Skimmed milk was used to substitute part of these additives in the samples. One formulation using passion fruit pulp/maltodextrin/skimmed milk (PMS) was prepared, and another using passion fruit pulp/gum arabic/skimmed milk (PGS). The behavior of curves was type III, according to Brunauer's classification. GAB models were fitted to experimental equilibrium data. The parameters obtained from GAB models was affected by the presence of additives. The behavior of the sorption isotherms for different temperatures are similar, noting only a small effect of...

ผลของสารพอกและวัสดุประสานต่างชนิดกัน ต่อคุณภาพเมล็ดพันธุ์ข้าวโพดไร่ขนาดเล็ก Thai Agricultural
Nongnuch Saenghin; Boonmee Siri.
In commercial corn production, small seed size is discarded from the seed lot and used as the animal feed, resulting in less profit to the seed industry. Therefore, the objective of this research was to increase seed size by seed pelleting methods. In this study, the types of filler pelleting materials and ratio of binder materials were investigated. The experiment was conducted at Seed Quality Test Laboratory of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Small seed size of hybrid corn that retained on grade 14/64” diameter sieve perforations were pelleted with seven different types and ratios of fillers (vermiculite, bentonite, pumice, calcium sulphate, calcium carbonate, charcoal and coconut) with four different types of binders...
