Intrinsic factors affecting the rate of starch digestion in foods are the physical form of food, shape and crystal structure of the starch granule, recrystallization and retrogradation, amylose-lipid complexes, native α-amylase inhibitors and non-starch polysaccharides [1]. For nutritional purposes, starch is classified into three types based on these intrinsic factors: rapidly digestible starc...
cyclodextrins (cds) are a family of cyclic oligosaccharides which are composed of α (1,4) -linked glucopyranose subunits. thebest-characterized forms are α, β and γ cd which are consisted of six, seven and eight d-glucose units, respectively. cyclodextrins are produced from starch by enzymatic degradation. these macrocyclic carbohydrates with polar internal cavities can form complexes with and ...
Heteropolysaccharides isolated from liquid cultures of nine Tremella species contained 0.3 to 1.2% protein, 2.7 to 5% ash, 0.9 to 3.4% acetyl groups, 76.5 to 84.2% carbohydrates and trace amounts of starch. The polysaccharides in aqueous solution were slightly acidic (pH 5.1 to 5.6). They consisted of the following monomeric sugars: fucose, ribose, xylose, arabinose, mannose, galactose, glucose...
A rice starch based film, reinforced with starch nanocrystals (prepared by submitting native granules of rice starch to acid hydrolysis at 40 oC) was prepared by casting film-solution on leveled trays. The influence of the content of starch nanocrystals (5 to 30%) on the mechanical, thermal and structural properties of rice starch films was investigated. The rice starch films showed an increase...
Sea lettuce (Ulva pertusa) is a nuisance species of green algae that is found all over the world. East-Asian species of the marine gastropod, the sea hare Aplysia kurodai, shows a clear feeding preference for sea lettuce. Compared with cellulose, sea lettuce contains a higher amount of starch as a storage polysaccharide. However, the entire amylolytic system in the digestive fluid of A. kurodai...
In a recent study, we observed that starch-rich diets used in mid lactation induced lower milk production persistency and higher body fat accumulation dairy ewes compared with goats. Because these species differences could be linked to hormonal mechanisms drive energy partitioning, the same experiment, explored evolution of metabolic status during test this hypothesis. Twenty mature Sarda 20 Sa...
Seagrass meadows form highly productive and valuable ecosystems in the marine environment. Throughout the year, seagrass meadows are exposed to abiotic and biotic variations linked to (i) seasonal fluctuations, (ii) short-term stress events such as, e.g., local nutrient enrichment, and (iii) small-scale disturbances such as, e.g., biomass removal by grazing. We hypothesized that short-term stre...
In this research, the rheological behavior and stability of suspensions containing Si3N4, Al2O3, Y2O3 and starch were investigated in order to use them in the starch consolidation casting of porous silicon nitride. Dolapix CE64 was used as the dispersant. Then, the effect of some parameters such as Si3N4 surface oxidation, dispersant content, solid loading and starch content on the viscosity an...
