摘要:
A saccharide composition comprising maltooligosyl derivatives of turanose and palatinose which can be readily produced, separated, and purified in a relatively-high yield from maltooligosylsucrose by allowing non-reducing saccharide-forming enzymes to act on aqueous solutions containing maltooligosylsucrose. These saccharides are reducing oligosaccharides with a mild and high-quality sweetness and can be used orally and parenterally, as well as being readily metabolized and used by living bodies.

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.

The invention provides a process for enabling the production of a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside that does not significantly cake even when the production yield of ascorbic acid 2-glucoside does not reach 35% by weight. The process for producing a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside, which comprises allowing a CGTase to act on a solution containing either liquefied starch or dextrin and L-ascorbic acid and then allowing a glucoamylase to act on the resulting solution to obtain a solution with an ascorbic acid 2-glucoside production yield of at least 27%, purifying the obtained solution to increase the ascorbic acid 2-glucoside content to a level of over 86% by weight, precipitating anhydrous crystalline ascorbic acid 2-glucoside by a controlled cooling method or pseudo-controlled cooling method, collecting the precipitated anhydrous crystalline ascorbic acid 2-glucoside, and ageing and drying the collected anhydrous crystalline ascorbic acid 2-glucoside.
摘要:
The present invention aims to provide a particulate composition containing anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic acid having a significantly, hardly solidifiable property compared to conventional ones in a grade for use in quasi-drugs; a process for producing the same; and uses thereof. The present invention solves the above object by providing a particulate composition containing anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic in an amount of over 98.0% by weight but less than 99.9% by weight, on a dry solid basis; or a degree of crystallinity of 90% or higher for anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic acid, when calculated based on a profile of powder X-ray diffraction analysis of the particulate composition, and a dynamic vapor sorption level of 0.01% by weight or lower, when kept at 25° C. under a relative humidity of 35% by weight for 12 hours after removal water in the particulate composition under nitrogen gas stream; and by providing a process for producing the same and uses thereof.

摘要:
Disclosed is a non- or substantially non-crystalline high trehalose content syrup, which is supersaturated in trehalose and which further comprises another dissolved saccharide in an amount at least as much as the amount of trehalose. The saccharide acts to prevent crystallization of trehalose. The saccharide may be a reducing monosaccharide, a non-reducing monosaccharide or an oligosaccharide. The supersaturated trehalose solutions are free from bacterial contamination even at ambient temperature.
摘要:
High-purity maltose is produced by applying a feed starch sugar solution with a maltose content of at least 70% to a column packed with a strongly-acidic cation exchange resin of alkali metal- or alkaline earth metalform; fractionating the feed solution by charging water thereto in a high-dextrin fraction, a high-dextrin.maltose fraction, a high-maltose fraction, a high-maltose.glucose fraction, and a high-glucose fraction, in the given order; and recovering the high-maltose fraction. This process constantly provides a fraction with a maltose content of 93% or higher, and enables industrial-scale production of a high-purity maltose much easier and at lower-cost than conventional processes.
摘要:
Maltopentaose is crystallized from a supersaturated solution of a high-purity maltopentaose, obtained by fractionation of a feed solution, containing maltopentaose along with additional higher and lower maltooligosaccharides, using a strongly-acidic cation exchange resin in a salt form (e.g. alkali- or alkaline-metal form). Crystalline maltopentaose is non-hygroscopic and non-deliquescent. A pulverulent solid containing crystalline maltopentaose is found substantially non-hygroscopic. Crystalline maltopentaose is favorably usable as the substrate to assay serum amylase. Crystalline maltopentaose and pulverulent solid containing the same are favorably usable to produce foodstuffs, pharmaceuticals, cosmetics, and chemicals.
