摘要:
A saccharide composition containing trehalulose, which is obtainable by allowing a maltose/trehalose converting enzyme to act on a sucrose solution to produce trehalulose, and collecting the resulting trehalulose-containing mixture. Since the enzyme converts sucrose into trehalulose in a relatively high yield and the conversion rate is controllable, a saccharide composition rich in trehalulose is readily obtained on an industrial scale.
摘要:
Microorganisms which are able to produce maltose/trehalose conversion enzyme, a novel enzyme, are cultivated in nutrient culture media with malose. During the cultivation, the microorganisms readily convert maltose into trehalose to accumulate trehalose in the cultures which yield saccharide mixtures with high trehalose contents when separated from insoluble substances. Removal of contaminant saccharides and subsequent crystallization readily yield trehalose in crystalline trehalose hydrate or anhydrous crystalline form. The trehalose and saccharide mixture containing the same commonly bear desirable properties including mild sweetness and superior stability which render them very useful in a variety of compositions indlucing food products, cosmetics and medicines.

Disclosed are novel non-reducing saccharide-forming enzyme, and its preparation and uses. The enzyme is obtainable from the culture of microorganisms such as Rhizobium sp. M-11 (FERM BP 4130) and Arthrobacter sp. Q36 (FERM BP-4316), and capable of forming non-reducing saccharides having a trehalose structure when allowed to act-on reducing partial starch hydrolysates. Glucoamylase and .alpha.-glucosidase readily yield trehalose when allowed to act on the non-reducing saccharides. These non-reducing saccharides and trehalose are extensively useful in food products, cosmetics and pharmaceuticals.

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:
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:
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.
