摘要:
The lactosucrose high-content powder according to the present invention is prepared by allowing an aqueous solution containing sucrose and lactose to act on a saccharidetransferring enzyme, removing concomitant saccharides in the resultant saccharide solution containing lactosucrose to obtain a solution having a high concentration of lactosucrose, i.e. lactosucrose content of 45 w/w % or more of the sugar composition, and spraydrying the resultant solution to obtain a powder having a high concentration of lactosucrose. The powder is incorporated in an orally- or parenterally-administrable product to obtain an orally- or parenterally-administrable product which exerts a selective growth-promoting-effect on a microorganism of the genus Bifidobacterium in vivo.

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:
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.

2-O-.alpha.-D-Glucopyranosyl-L-ascrobic acid is crystallizable in its supersaturated solution. Crystalline 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid is substantially nonhygroscopic, free flowing, free of deliquescence, consolidation and direct reducing activity, but is readily soluble in water. Because of these characteristics, crystalline 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid is handleable with an ease, and superiorly high in stability and physiological activities. Thus, crystalline 2-O-.alpha.-D-glucopyranosyl-L-acorbic acid is favorably useful in vitamin C-enriching agents, foodstuffs, pharmaceuticals and cosmetics.
摘要:
There is provided a process to prepare maltose powder containing crystalline beta-maltose hydrate, comprising concentrating an aqueous solution of a high-purity maltose having a maltose content of at least 85% DS to a moisture content below 10 w/w %, partially crystallizing alpha-maltose in the syrup, and crystallizing beta-maltose hydrate in the same syrup while converting the resultant crystalline alpha-maltose into crystalline beta-maltose hydrate. Use of the invention enables consistently high-quality maltose powders at a reduced drying cost.
摘要:
There are disclosed a novel desiccant containing anhydrous maltose and dehydration of hydrous matters, e.g. food, pharmaceutical and cosmetic, therewith. Such hydrous matters are dehydrated without causing alteration or deterioration by incorporating anhydrous maltose into the hydrous matters to convert the anhydrous maltose into crystalline beta-maltose hydrate. The anhydrous maltoses usable in the invention are anhydrous crystalline alpha-maltose, anhydrous crystalline beta-maltose and anhydrous amorphous beta-maltose, specifically, those in pulverulent form.

摘要:
A novel dehydration method using anhydrous glycosylfructose as the desiccant is disclosed. Anhydrous glycosylfructose is converted to the crystalline hydrate and acts as the desiccant when incorporated into a hydrous matter. Natural saccharides such as palatinose, raffinose, erlose, and melezitose can be used. The dehydration is applicable to hydrous matters, such as those of foods, pharmaceuticals, cosmetics, and their materials and intermediates.
摘要:
A novel dehydration process using anhydrous aldohexose as the desiccant is disclosed. Anhydrous aldohexose is converted to crystalline hydrate and acts as the desiccant when it is incorporated into a hydrous substance. Natural saccharides such as glucose, galactose, and mannose are suitable for the aldohexose. The dehydration is applicable to hydrous matters, such as those of foods, pharmaceuticals, cosmetics, and their materials and intermediates.
