赤藓醇

This paper introduces the current status and development tendency of the research and production of erythritol, and discusses the biosynthetic pathway of erythritol produced by an osmophilic yeast.

现介绍赤藓糖醇的生产和研究现状，耐高渗酵母赤藓糖醇的合成途径和赤藓糖醇的应用，并对其研究和发展提出看法。

Compared with xylitol, erythritol in low concentration has weaker effort on the growth and acid production of S.mutans, while having stronger effort in high concentration.

对比木糖醇，低浓度下赤藓糖醇对变异链球菌生长和产酸的抑制作用较弱，高浓度下赤藓糖醇的抑菌效果更强。

Because erythritol is rapidly absorbed in the small intestine and rapidly eliminated by the body within 24 hours, laxative side effects sometimes associated with excessive polyol consumption are unlikely when consuming erythritol containing foods.

由于赤藓糖醇是迅速吸收，在小肠和迅速消灭，身体在24小时内，泻药的副作用，有时与过量多元醇消费不大可能消费时，赤藓糖醇含有食品。

It indicated that the growth and acid production of S.mutans were higer in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while lower in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration.

在8%、12%、16%浓度下，赤藓糖醇培养基的A值较木糖醇培养基低，pH值较木糖醇培养基高，说明变异链球菌在含8%、12%、16%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基低。

This text distinguish to development erythritol,physics and sweet flavor characteristic of erythritol,the circumstance of different from erythritol is in the food industry realm application made the synopsis describe.key phrase: erythritol,development history

本文分别对赤藓糖醇的发展史；赤藓糖醇的紫光官方及甜味特性；和赤藓糖醇在食品工业不同领域应用情况作了简要阐述。

Results The data of A were higher in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while lower in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration. The data of pH were lower in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while higer in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration.

结果 在0.5%、1%、2%浓度下，赤藓糖醇培养基的A值较木糖醇培养基高，pH值较木糖醇培养基低，说明变异链球菌在含0.5%、1%、2%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基高。

Spherical yeast OS-194 is an only erythritol production osmophilic yeast. 10 percent of glucose ,0.5 g/dL for yeast extract and 0.1 g/dL for urea were the best components of medium,which obtained high erythritol yield by OS-194.The optimum culture conditions were 35℃,150 rpm,and 4 d.

球拟酵母OS-194是一株单产赤藓糖醇的耐高渗酵母，该菌株高产赤藓糖醇的最佳培养基配方为：葡萄糖10 g/dL，酵母膏0.5 g/dL，尿素0.1 g/dL。

Based on the molecular structures, sugar alcohols can be classified into Mono sugar alcohol (such as erythritol, xylitol, sorbitol and mannitol ) and Disaccharide alcohol (such as maltitol,lactitol and isomaltitol).

糖醇是醛糖或酮糖的羰基经氢化还原成羟基的多元醇；按其结构可分为单糖醇(如四元赤藓糖醇、五元木糖醇、六元山梨糖醇和甘露糖醇)，双糖醇(如麦芽糖醇、乳糖醇、异麦芽酮糖醇)。

Structure Design and Modification of Mannitol-polylactide Tissue Engineering Materials;2. Based on the molecular structures, sugar alcohols can be classified into Mono sugar alcohol (such as erythritol, xylitol, sorbitol and mannitol ) and Disaccharide alcohol (such as maltitol,lactitol and isomaltitol).

The erythritol is produced industrially by Zhongshi Gerui biotechnology Co., Ltd., Zibo by means of utilizing Candida lipolyti developed by China Food Fermentation Industry Inst. And with the preservation number of CGMCC No.1431 as the high erythritol yield spawn and deep liquid fermentation of glucose. The erythritol is used as functional sweetening agent in sugar substitute for diabetics, low calorie sugar, low calorie beverage, low calorie cake, low calorie candy, low calorie milk product, etc.

具体是指淄博中食歌瑞生物技术有限公司与开发出赤藓糖醇高产菌种――解脂假丝酵母 Candida lipolytic 的中国食品发酵工业研究院合作，利用保藏编号为 CGMCC No.1431的解脂假丝酵母 Candida lipolytica 菌种，用葡萄糖深层液态发酵，工业规模制取的赤藓糖醇；作为功能性甜味剂，在下述产品中的应用：糖尿病人代用糖，低热量佐餐用糖，低热量饮料，低热量糕点，低热量糖果，低热量奶制品和低热量冰激淋或低热量雪糕或低热量冰糕。
