A high oozed-resisting yeast strain separated from pollen and honey by efforts in many years. The strain was complex induced and cultivated, its high sugar resist ability reached to over 50%. Taking starch hydrolyzed sugar as material, the yield of erythritol fermented in 100 cubic meter fermentor was over 180g/L and the transformation was over 50%. At present, the erythritol fermentation and extract technologies have been completed middle-scale and productive experiments, the purity of products reached to 99%, the index of physical chemistry and health has been to the export product requirements. The technology has been identified by Shandong Science & Technology Department on Oct.28 2006. It was considered by the idenfication that the technology laid a foundation for industrial production of erythritol and reached to the world level. As the erythritol has the properties of low moisture, low caloricity, better crystallinity and cannot cause decayed tooth, it is suitable to be applied in diabetics and food industry as a new functional sweetener.
In chemistry, the erythrotol can be used in compound of alkyd resin, polyester, polyether, paint and explosive as organic synthetic intermediate.
In cosmetic, the erythritol can replace glycerine for preventing cosmetic deteriorate because most of microbiology cannot utilize erythritol.
In addition, the erythritol can be substrate to compose some rare matter eg. it is used as material to produce erythrose. With the development of technology, the erythritol utilization will keep exploring.
As starch resource is abundant, the fermented erythritol has powerful competition on the market. The price is about 45-50 thousand yuan/ton, the cost of ton is of 18 thousand yuan. If 5000 ton /year of erythritol is produced, the income will be 240 million yuan and the benefit and tax will be 150 million yuan.
