摘要:
An object of the present invention is to provide a method for industrially producing a branched glucan having a cyclic structure. The method for producing a branched glucan having a cyclic structure comprises the steps of: (1) preparing a mixed liquid which contains a branching enzyme in which starch granules are suspended at a concentration of 5% by weight or more and 50% by weight or less, and allowing the branching enzyme to act on starch in the starch granules, wherein a temperature of the mixed liquid at the time of preparation is 0° C. or higher and not higher than the gelatinization starting temperature of the starch granule; and (2) elevating the temperature of the mixed liquid to 85° C. or higher and 129° C. or lower, wherein in the method, none of α-amylase, β-amylase, amyloglucosidase and a transglucosidase is added to the mixed liquid.
摘要:
An object of the present invention is to provide a glucosamine-containing glucan, a modified product and a conjugate thereof. The glucosamine-containing glucan of the present invention is a glucosamine-containing glucan wherein the glucan has a plurality of non-reducing ends and at least one glucosamine residue is bound via an α-1,4-bond to each of two or more non-reducing ends of the branched α-1,4-glucan, but no glucosamine residue is present at a position other than the non-reducing ends of the branched α-1,4-glucan, wherein the degree of polymerization of the glucan is 15 or more and 4×105 or less. The glucosamine-containing glucan of the present invention can be provided by allowing an α-glucan phosphorylase to act on an aqueous solution comprising a branched α-1,4-glucan and glucosamine-1-phosphate.
摘要:
The present invention is directed towards improving blood glucose levels, visceral fat levels, blood cholesterol levels, neutral fat levels, etc. by oral administration of enzyme synthesized glycogen (ESG). The invention is further directed towards the intake of food by a subject that comprises ESG as a carbohydrate to improve blood glucose levels, visceral fat levels, blood cholesterol levels, neutral fat levels and the like.
摘要:
An object of the present invention is to provide a uronic acid-containing glucan or a modified product thereof. The glucuronic acid-containing glucan of the present invention is a glucuronic acid-containing glucan in which a glucuronic acid residue is bound to at least one non-reducing end of a glucan, and the glucan is a branched α-1,4 glucan or a linear α-1,4 glucan. The glucuronic acid-containing glucan of the present invention can be provided by allowing α-glucan phosphorylase derived from Aquifex aeolicus VF5 to act on glucuronic acid-1-phosphate to thereby transfer a glucuronic acid residue to the non-reducing end of the receptor glucan.
摘要:
The present invention provides glucans and derivatives thereof which are useful as raw materials in the starch processing industries, food and drink compositions, food additive compositions, and starch substitutes for biodegradable plastics, and processes for preparing the same. Particularly, it provides glucans and derivatives thereof having excellent properties such as higher solubility in water than conventional starches, lower viscosity and the glucans are not subject to retrogradation which is observed in conventional starches, and which are capable of preventing the retrogradation of starches.
摘要:
The present invention provides a technique for synthesizing a carotenoid composition by a genetic recombination technique. A transformant in which a first promoter, an upstream gene of a carotenoid biosynthesis gene including a crtY and crtZ operably linked to the first promoter, a second promoter having higher promoter intensity than the first promoter, and a ZEP gene and a CCS gene operably linked to the second promoter have been introduced into a host cell.
