新型变性淀粉多孔淀粉的制备

<正>我国每年生产玉米几千万吨,由于玉米的食用品质差,库存积压严重,成为粮食流通体系中的一大难题。研究玉米资源的开发利用技术,提高玉米资源的利用率迫在眉睫。以玉米为原料,利用生物技术进行玉米深加工,开发新产品,是玉米的开发利用的有效途径。 变性淀粉是淀粉深加工产品之一,多孔淀粉作为一种新型的变性淀粉,其研究和应用正逐步受到人们的重视。多孔淀粉是指表面布满许多小孔的特殊淀

Studies of porous starch production

The adsorption oil ratio was used as a index to value the porous starch, and the optimal conditions of porous starch production were obtained by single factor and orthogonal experiment: the reaction temperature was 55℃,the reaction time was 28h, the pH was 5.6, the solid concentration was 60%(w/v), the quantity of complex enzymes was that hydrolyzing 50% raw starch theoretically. A good result was also obtained in large-scale experiment.
