摘要:
Disclosed is a novel non-reducing oligosaccharide with neotrehalose structure represented by the general formula as shown by: ##STR1## The oligosaccharide is obtainable by exposing an aqueous solution containing neotrehalose to a saccharide-transferring enzyme, and has a superior stability, reduced sweetness, appropriate viscosity, no susceptibility to crystallization and less fermentability. These features make it very useful in various compositions including foods, beverages, cosmetics and pharmaceuticals.
摘要:
.alpha.-Glycosyl hesperidin, a novel hesperidin derivative wherein equimolar or more D-glucose residues are bound to hesperidin via the .alpha.-bond, is formed by a saccharide-transferring enzyme in a liquid containing hesperidin and .alpha.-glucosyl saccharide. The .alpha.-glycosyl hesperidin is easily recovered from the reaction mixture with a synthetic macroporous resin. .alpha.-Glycosyl hesperidin is superior in water-solubility, substantially tasteless and odorless, free of toxicity, and readily hydrolyzable in vivo into hesperidin and D-glucose to exhibit the physiological activity inherent to hesperidin. Thus, .alpha.-glycosyl hesperidin is favorably usable in vitamin P-enriching agents, foods, beverages, tobaccos, foods, pet foods, pharmaceuticals for susceptive diseases, cosmetics and plastics.
摘要:
Disclosed is an alkali-treated bagasse prepared by softening a bagasse with calcium oxide together with or without sodium hydroxide while preventing the substantial decomposition of cellulose and hemicellulose, a bagasse feed and a fermented bagasse feed prepared from the alkali-treated bagasse, and their preparations and uses as well as bacteria for fermenting the alkali-treated bagasse. These bagasse and bagasse feeds save sugar-refinery industries from the difficulties to treat bagasse deemed as an unutilized industrial waste, and livestock farming industries from the shortage of roughage, and further is extremely significant in agriculture, industries of sweetening products, feed industries and livestock product processors. A bacterium strain particularly useful for the fermentation is Enterococcus faecium FERM BP-4504.
摘要:
Oligoglucosylfructosides wherein an oligoglucosylfructoside having a polymerization degree of 2 or 3 glucose units are recovered in a high purity from a feed solution additionally containing substantial amounts of higher- and lower-oligosaccharides by sequentially admitting predetermined volumes of the feed solution and water to the column of a strongly-acidic cation exchange resin in alkaline-earth metal form; sequentially separating the effluents from the column into the first fraction rich in the higher oligosaccharide, the second fraction rich in the higher oligosaccharide but highly contaiminated with the oligoglucosylfructoside, the first fraction rich in the oligoglucosylfructoside, the fourth fraction rich in the oligoglucosylfructoside but highly contaminated with the lower oligosaccharide, and the fifth fraction rich in the lower oligosaccharide; and recovering the third fraction. The second- and fourth fractions can be admitted to the column so as to decrease the amount of elution water and also to recover the high-oligoglucosylfructoside fraction in a much higher concentration and recovery yield.
摘要:
Proteinaceous bioactive substances (including lymphokine and peptide hormone) in dry solid are extremely stabilized by the presence of the specific polysaccharide mainly composed of repeating maltotriose units. Pullulan, elsinan, and their partial hydrolysates are feasible as the polysaccharide. The weight ratio of the polysaccharide to the substance which effectively stabilizes the latter substance is at least 0.5 on the basis of dry solids. The dry solid is advantageously usable as a test reagent, injection, granule, tablet, suppository or ointment.
摘要:
Crystalline .alpha.-maltose extremely improves the stability, taste quality and shelf life of noodles and alimentary pastes, as well as decreases the addition of water in their preparation. Since crystalline .alpha.-maltose exerts an activity of binding flour, a satisfiable dough can be obtained with a reduced addition of water. In corporation of crystalline .alpha.-maltose into flour yields a premixed flour for preparing noodles and alimentary pastes, and the addition of water thereto attains an excellent dough products.
摘要:
A novel EPA/CD inclusion compound and a food product containing the same are disclosed. The undesirable odor of EPA is masked by including it into such EPA/CD inclusion compound. Gamma-CD is most favorable because it includes much more EPA, and highly stabilizes it. The EPA/CD inclusion compound is advantageously usable in perorally- or parenterally-usable products directed to the promotion or maintenance of health.
摘要:
A novel molded article exhibiting a gradual disintegration effect is prepared with pullulan. The effect is imparted by incorporating heteromannan into a pullulan molded article in an amount not exceeding the weight of the pullulan used. Galactomannans (e.g. guar gum, tara gum, and locust bean gum) and glucomannans (e.g. konjak mannan) are feasible as the heteromannan. The molded article is advantageously usable for industrial materials, pharmaceuticals, consumers' products, etc.
