摘　　要：黄原胶作为一种生物多糖,已被广泛应用于食品和化工行业中。然而,使用野油菜黄单胞菌,通过玉米淀粉、大豆粉直接发酵得到的发酵液中往往含有大量杂质。为解决这一问题,文章通过EDTA-2Na和双酶法去除了大部分杂质,并用醇法析出了黄原胶,在50℃下真空干燥,最终得到了高透光度、高黏度的黄原胶产品。Xanthan gum is a biopolysaccharide,which has been currently widely used in the food and chemical industries.However,there are a large number of impurities in the fermentation broth obtained by direct fermentation of corn starch and soybean flour with Xanthomonas campestris.In order to solve this problem,most of the impurities are removed by EDTA-2Na and dual enzyme method,and xanthan gum is precipitated by alcohol method.It is then vacuum dried at 50℃to finally obtain high transparency and high viscosity xanthan gum products.
