生产分子量降低的糖的方法

Process for producing sugar in which molecular weight is lowered
摘要：
A process for producing a saccharide having a lowered molecular weight, which comprises irradiating an electron beam to a polysaccharide fraction. Also, a process for producing a saccharide having a weight average molecular weight of n (Da), which comprises irradiating an electron beam to a polysaccharide fraction which has a weight average molecular weight of M (Da) and is in a solid state at a dosage of d (kGy) that satisfies the following equation: n=Mead (wherein M is a number of 5,000 to 70,000; n is an optional positive number; e is the base of natural logarithm; and a is a number of −0.008 to −0.004). Furthermore, a process for producing hyaluronic acid having a lowered molecular weight, which comprises irradiating an electron beam to a hyaluronic acid fraction.
摘要（中）：

一种生产低分子量糖的方法，其包括将电子束照射到多糖级分。 另外，重均分子量为n（Da）的糖类的制造方法，其特征在于，包括向重均分子量为M（Da）的多糖部分照射电子束，并且在 满足以下等式的d（kGy）的剂量：<？in-line-formula description =“In-line formula”end =“lead”？> n = Me -formulae description =“在线公式”end =“tail”？>（其中M是5,000到70,000的数; n是可选的正数; e是自然对数的基数; a是 - 0.008〜-0.004）。 此外，具有降低分子量的透明质酸的制造方法，其包括将电子束照射到透明质酸部分。
