Provedor de dados: 75
Autores: Nascimento,Revenli Fernanda do; Canteri,Maria Helene G.
ABSTRACT Offering new products obtained from potatoes is a market opportunity which may increase and motivate the consumption of this tuber. It also can contribute for waste reduction and ensure market for growers. Thus, we aimed to produce potato flour and to evaluate the effect of blanching on the physiochemical characteristics of this product after 3-month storage at room temperature. Potatoes cultivar Agata were used to make unblanched and blanched flour, through thermal treatment at 97°C for 5 min. The unblanched potato flour presented significantly smaller contents of moisture (p= 0.006), proteins (p= 0.001) and soluble fibers (p= 0.024), as well as color alteration. However, it presented higher phenolic compound content (23.77%). The blanched potato...

Microflores sulfatoreductrices en milieu subantarctique. Relations avec quelques parametres physicochimiques et biologiques. (Microflores totales et heterotrophes)
Provedor de dados: 5
Autores: Delille, D; Bouvy, M.
The archipelago of Kerguelen with its complex fjord distribution is particularly interesting for the study of anoxic systems. Between 1968 and 1972, several stations were investigated fortnightly. One of these was further sampled weekly throughout 1982. Each sample series of sediment included the superficial aerobic and subsuperficial anaerobic levels. Each level was examined for direct epifluorescent counts, heterotrophic and sulfate-reducing bacterial numbers by M.P.N. methods, organic carbon and sulfide measurements. Sulfate-reducing bacteria seemed less related to total biomass than the heterotrophic microflora, the latter being dependent on organic supplies. The hydrogen sulfide production was directly related to the presence of sulfate reducers;...

Mineral and organic soluble forms of zinc, iron and copper: Distribution in the Seine Estuary.
Provedor de dados: 5
Autores: Gandon, R; Guegueniat, P; Fischer, J; Wartel, M.
One characteristic of the Seine Estuary system is the process of sediment resuspension by the specific hydrodynamics of this environment. It's the main factor of trace metals transport. Autotrophic activities also have an effect on the estuary, by pH variation. The behavior of soluble and organic copper, iron, have been studied in relation to salinity in and out of the estuary. The results are compared with those of other estuaries.

Four seasonal compaigns providing a sampling of 15 stations each followed during half a tide cycle, i.e. 120 water samples permit the definition of the main hydrobiological features of Marennes-Oleron Bay: salinity and turbidity, phytoplanktonic biomasses, ATP concentrations. The authors suggest that a new way of adapted sampling to their objectives, will work out in the future by sampling during tidal cycles but as frequently as possible.

Autores: Ramesh, A; Venugopalan, V.
Information available on the association of luminous bacteria with marine invertebrates is limited. Hence qualitative and quantitative investigations were undertaken with a view to understand the distribution of luminous microflora in relation to the environmental factors and also in the gut of two marine gastropods, Aplysia benedicti Eliot and Bullia tranquebarica (Roding) from Porto Novo (11 degree 29'N, 79 degree 46'E) waters of the East coast of India. The gut of the gastropods harboured maximum number of luminous bacteria when compared to the water and sediment. Qualitative analysis revealed the presence of two luminous bacterial components, viz. Vibrio harveyi and V. fishceri. V. fischeri was not found in association with A. benedicti . The isolates...

Potato tubers(cv.，Inka-no-mezame，Inka Red，Kitamurasaki，Danshaku and Kitahime)were stored at 4℃ for about 8 months and changes in physicochemical properties of starches isolated from potatoes were examined periodically during storage. Both average granule size and phosphorus content of starches were decreased during low temperature storage. However，  the blue values of starches from five cultivars were increased with the increasing duration of storage period. These changes may suggest that amylopectin of the outer surface of starch granules is gradually converted to sugars during cold storage. There was no clear tendency regarding swelling power and solubility of starches during storage. From RVA analysis，the pasting temperature of Inka Red and...

Water quality trends and input loads to Lake Nakuru
Provedor de dados: 20
Autores: Kulecho, Andrew; Muhandiki, Victor.
Water quality trends of Lake Nakuru, Kenya and its feeder streams were monitored in 2001-2004. Water samples were obtained from eleven stations in the lake and five points on inflowing streams. The items monitored were physico-chemical and biological components. The drainage basin was characterized by recurrence of dry spells throughout the period with water losses in the lake exceeding the amount received to cause a fall in water volume. The lake water salts content rose – conductivity and alkalinity reached 58 ms/cm and 5,200 mg/l respectively. PH was more or less constant (10.00 – 10.36). Daytime oxygen concentration in the mid-lake system rose (to greater than 20 mg/l) while remaining low in the inflow portions of the lake. On one occasion, the lake...

Effect of plantain ( Musa paradisiaca L. cv. Dominico Harton) peel flour as binder in frankfurter-type sausage
Provedor de dados: 109
Autores: Rosero-Chasoy,Gilver; Serna-Cock,Liliana.
Abstract Agroindustrial residues such as plantain (Musa paradisiaca L. cv. Dominico Harton) peel have functional properties, which made them suitable for use as a food ingredient. The aim of this research was to evaluate plantain peel flour (PPF) as a binder in the production of frankfurter- type sausage. Five formulations were prepared in which wheat flour (WF) was replaced by PPF as follows: 25%, 50%, 70% and 100%, respectively. Once the sausages are obtained, water retention capacity (WRC), emulsifying stability (ES), and pH, were evaluated. When comparing treatments with the control sample, it was found that replacing up to 50% of WF by PPF, significantly increased WRC by 7.5%. When replacing 25%, Es, there were no statistically significant changes...

Abstract The aim of the present study was to investigate the effect of Lactobacillus plantarum adhesion to the surface of olives during storage through studying the interaction between the surfaces of the olives and L. plantarum. The results showed that the total number of adherent L. plantarum increased exponentially from 1.2 × 106 to 1.3 × 108 cfu/g. Images obtained using environmental scanning electron microscopy (ESEM) after 4 days of storage revealed that the olive surface was covered with a uniform and compact biofilm constituted of L. plantarum and yeast. Physicochemical analysis of surface of L. plantarum revealed that it was hydrophilic (Giwi &gt; 0 mJ/m2). The surface of the olives also appeared to be hydrophilic (Giwi = 3.28 mJ/m2). The...
