Soluble flaxseed gum (SFG) extracted at different temperatures (25, 40, and 60 °C) was analyzed in relation to the yield, polysaccharides phenolics composition, surface charge, color, rheological properties. The yield of SFG extract increased as extraction temperature increased. xylan main component regardless temperature, but a reduction substituents on xylose chain observed when increasing temperature. phenolic compounds were also affected by influencing antioxidant capacity gum. For all...
The effluent of a brewery, complete or diluted with deionised water normal culture medium, was used as the growth nutrient medium for Chlorella vulgaris and consortium obtained from autochthonous flora that (microalgae, cyanobacteria bacteria). cultures were exposed to continuous light aeration, at 25°C, evaluated by direct counting (C. vulgaris) chlorophyll determination (autochthonous flora). Total protein lipid content, amino acid fatty profiles in produced biomass determined. highest...
Haematococcus pluvialis Flotow and Dunaliella salina Teodoresco are commercially important because of their ability to accumulate very high carotenoid contents. However, use is hindered by slow growth rates. This paper reports a study on the effects two regulators, 2,4-D (2,4-dichlorophenoxyacetic acid) kin (kinetin), in concentrations 0, 0.5, 1.0 2.0 mg l-1 each factorial design (24 combinations), as possible means enhancing rates.After 12-13 days treatment with plant hormones, D. showed...
Abstract BACKGROUND: This research was undertaken to study the effects of different cut‐types (cube, parallelepiped, cylinder and sphere) on quality shelf‐life papaya cv. Sunrise Solo. Physicochemical analyses were carried out during 10 days storage at 4 °C determine colour, firmness, pH, titratable acidity, total soluble solids, weight loss vitamin C content. Microbiological analysis sensory evaluation also performed. RESULTS: Papaya spheres (1.55 cm radius) presented most favourable...
The effects of chemical dips and edible coatings on firmness colour fresh-cut banana (cv. Cavendish) from Madeira Island were investigated. Two calcium salts, chloride lactate, first investigated for the during four days storage at 5°C. Firmness evaluated after a three-minute dipping or followed by coating five tested consisted pectin, alginate, carboxymethylcelullose, carrageenan chitosan solution. Dip with 1% (w/v) chloride, 0.50% ascorbic acid 0.75% cysteine was most efficient treatment...
Cinnamon is a spice widely used as flavouring agent in foodstuffs. Despite its commercial availability and low cost, C. burmannii aqueous extracts obtained by decoction originate high viscous solutions (1545 cP) when compared with verum (51 cP), preventing broad use food industry. Following the hypothesis that cinnamon polysaccharides are responsible for this viscosity, work, hot water-soluble from were structurally characterized, using comparison. The results showed had higher content of...
Salicornia is a halophytic plant that grows near salt marshes and salted wetlands, very rich in vitamins, minerals highly unsaturated oils. Because of its biochemical composition despite salinity, considered gourmet product. Since stems present short shelf life, the aim this work was to evaluate effect controlled atmosphere on quality ramosissima during four weeks at 4°C. Vitamin C chlorophyll contents were determined, microbiological sensory analyses performed. shoots preserved better...
