摘要： 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-ascorbic acid is favorably useful in vitamin C-enriching agents, foodstuffs, pharmaceuticals and cosmetics.

摘要： Disclosed is a process whereby enzymes are immobilized on granular diatomaceous earth. The process involves treating the diatomaceous earth with a polyamine compound having pendant amino groups to cause the polyamine to adhere to the diatomaceous earth leaving pendant amine groups free to react further. The free amine groups are derivatized by treatment with a difunctional compound having amine reactive moieties, so that free amine groups of an enzyme or enzymes can be covalently bound to the polyamine via the amine reactive compound.

摘要： Malt having a high content of alpha-1,6-hydrolase activity is prepared by germinating previously steeped barely until the average acrospire reaches a length of at least 11/4 times the average length of the kernals and it contains at least 55 units of alpha-1,6-hydrolase activity per gram of malt. The malt provides more complete hydrolyzing of starch to glucose and maltose, and it is useful in producing low carbohydrate beer, in producing distilled alcoholic beverages and in producing maltose syrup.

摘要： A culture filtrate of Cladosporium resinae (Strain ATCC No. 20495) has been found to contain a mixture of starch-degrading enzymes capable of bringing about efficient conversion of starch and pullulan into glucose. Culture conditions resulting in optimal production of the pullulan degrading activity been established. The amylolytic enzyme preparation obtained by culturing the fungus under these optimal conditions has been fractionated by ion-exchange and molecular sieve chromatography and shown to contain at least four enzymes, a maltase, .alpha.-amylase and two glucoamylase-type enzymes including a novel exo-pullulanase. The maltase and glucoamylase enzymes have been purified to homogeneity and their substrate specificity investigated. Both the mixture and the exo-pullulanase can be used in the manufacture of dextrose from starch. Alone or in conjunction with appropriate other starch-degrading enzymes the mixture or the exo-pullulanase may be used in the production of specific starch conversion products, including fructose syrups. Both the mixture and the exo-pullanase are useful in increasing the fermentability of high DE starch conversion products and may be useful in the production of low calorie alcoholic beverages.
