摘要:
Disclosed is a process for producing a high &agr;G-AA content product, which comprises the steps of: contacting a solution as a material solution, containing &agr;G-AA, L-ascorbic acid, and a saccharide(s), with an anion exchange resin packed in a column to adsorb the &agr;G-AA and L-ascorbic acid on the anion exchanger; washing the anion exchanger with water to remove the saccharide(s) therefrom; feeding to the column an aqueous solution, as an eluent, of an acid and/or a salt with a concentration of less than 0.5 N to fractionate a fraction rich in 2-O-&agr;-D-glucopyranosyl-L-ascorbic acid and a fraction rich in L-ascorbic acid; and collecting the former fraction.

Disclosed are a method for inhibiting trimethylamine formation per se from raw fishery products by incorporating trehalose and/or maltitol, an agent having trehalose and/or maltitol as effective ingredients to inhibit trimethylamine formation per se from raw fishery products, and an edible fishery product with satisfactory flavor and taste obtained by using the method or the agent.
摘要:
A hard candy with a relatively-high moisture and hardness, and process of the same. The levels of moisture and hardness are respectively from about 3.5% to about 10%, and at least 4.0 kg as a penetration strength when measured by a rheometer. The hard candy is characteristic of a relatively-high transparency, insubstantial stickiness to the teeth, and lesser stimulation to the teeth.
摘要:
A method for improving the aftertaste of sucrose without lowering the sweetening power of sucrose, which comprises incorporating trehalose into sucrose in an amount of 2-12% to the sucrose, on a dry solid basis. The method produces saccharide compositions and food products having improved aftertaste of sucrose without lowering the sweetening power of sucrose.
摘要:
A kojibiose phosphorylase which hydrolyzes kojibiose in the presence of an inorganic phosphoric acid to form D-glucose and &bgr;-D-glucose-1-phosphoric acid, forms kojibiose and an inorganic phosphoric acid from &bgr;-D-glucose-1-phosphoric acid, and catalyzes the transfer reaction of glucosyl group to other saccharides using &bgr;-D-glucose-1-phosphoric acid as a saccharide donor. The enzyme is obtainable from natural sources such as microorganisms of the genus Thermoanaerobium, and obtainable by recombinant technology. Kojibiose phosphorylase is used to transfer glucose from glucose-1-phosphate to acceptor saccharides to produce &agr;-D-glucosyl-1(1→5)-L-sorbose, kojibiosylglucose, kojibiosylglucoside and kojibiosylfructoside.
摘要:
An enzyme, which has a molecular weight of about 57,000-120,000 daltons on SDS-PAGE and a pI of about 3.8-5.1 on isoelectrophoresis using ampholyte, converts maltose into trehalose and vice versa. The enzyme was isolated from microorganisms of the genera Pimelobacter, Pseudomonas and Thermus. By using the enzyme, trehalose is readily formed from a commercially available maltose in an industrial scale and a relatively-low cost. Trehalose and saccharide compositions containing the same, which are preparable with the enzyme, are suitably used in food products, cosmetic compositions and pharmaceutical compositions.
摘要:
A highly digestible, good preference, relatively high-quality fermented formula feed which is obtainable by mixing a soybean feed material and a wheat splinter capable of decomposing phytin in an amount of not less than that of the soybean feed material, d.s.b., and subjecting the mixture to a lactic acid fermentation under humid conditions.
摘要:
The present process for producing a high .alpha.-monoglucosyl hesperidin content product is characterized in that it comprises the steps of contacting glucoamylase and .alpha.-L-rhamnosidase simultaneously or randomly with a solution containing .alpha.-glucosyl hesperidin and hesperidin to obtain a mixture; crystallizing and separating .alpha.-monoglucosyl hesperidin in and from the mixture; and collecting the resulting .alpha.-monoglucsyl hesperidin. From solutions containing .alpha.-glucosyl hesperidin and hesperidin, the present invention facilitates the production of a high .alpha.-monoglucosyl hesperidin content product which does not substantially contain hesperidin, .beta.-monoglucosyl hesperetin, and hesperetin, and has an extremely-superior water-solubility.
摘要:
An agent for improving the blood circulation, which contains as an effective ingredient glycosyl vitamin P such as glycosyl hesperidin and glycosyl rutin. The agent improves the blood circulation in humans to effectively relieve muscular rigidity.
摘要:
A kojibiose phosphorylase which hydrolyzes kojibiose in the presence of an inorganic phosphoric acid to form .beta.-glucose and .beta.-D-glucose-1-phosphoric acid, forms kojibiose and an inorganic phosphoric acid from .beta.-D-glucose-1-phosphoric acid, and catalyzes the transfer reaction of glucosyl group to other saccharides using .beta.-D-glucose-1-phosphoric acid as a saccharide donor. The enzyme is obtainable from Thermoanaerobium brockii and obtainable by recombinant technology.
