青海高原菊芋(Helianthus tuberosus L.)开发研究述评

对在青海高原开发野菜资源菊芋(Helianthus tuberosus L.)进行了述评。介绍了菊芋的生物学和生态学特性，栽培管理方法。菊芋块茎富含菊糖，经现代生物技术深加工后，可得菊粉(Inulin)。再以菊粉为原料经菊粉酶(Inulinase EC3．2．1．7)水解可制成低聚果糖(Oligosaccharides)、超高果糖浆(ultrahigh fructose Glucose Syrups UHFGS)。菊粉、低聚果糖、超高果糖浆都是当今食品工业的一种全新的多功能配料，是全水溶性膳食纤维，同时还是双歧杆菌增殖因子，应用前景非常广阔。

A Review of Jerusalem Artichoke(Helianthus tuberosus L.)Developing in Qinghai Plateau

This paper reviewed the biological and ecological characteristic and the planting management of the Jerusalem artichoke(Helianthus tuberosus L.) in Qinghai plateau. The Jerusalem artichoke contained rich in inulin .After processing achieved alantin by modern biological technology. The inulinase change them into oligosaccharides and ultrahigh fructose glucose syrups(UHFGS) by hydrolyzing.The inulin and oligosaccharide and UHFGS were new manifold burden and whole water-soluble meals fiber. At the same time they were propagation factor of lactobacilius bifidus . The development of Jerusalem artichoke must have a extensive prospect.
