果胶是一种亲水性植物胶,由α-1,4糖苷键联接的半乳糖醛酸与鼠李糖、阿拉伯糖、半乳糖等中性糖聚合而成,是重要的食品添加剂之一.目前全世界果胶的年需求量近2万t,据有关专家预计果胶的需求量在相当长的时间内仍将以每年l5%的速度增长.我国每年消耗约1500t以上果胶,80%依靠进口,需求量与世界平均水平相比呈高速增长趋势.大力开展果胶的研究与开发,探索提高果胶产量和质量的新方法和新资源,不仅能为我国食品加工领域广泛地应用优质果胶提供理论依据,而且将推动国产果胶生产的发展.本文介绍了果胶的化学结构及提取用原料,以及果胶的应用范围,并结合国内外近年来的研究成果,系统综述了果胶的提取、...

Pectin is a complex polysaccharide consisting mainly of esterified D-galacturonic acid resides in an α-(1-4)chain.It also contains other neutral sugars presented in side chains such as xylose,galactose and arabinose.It is one of the important food additives.It is estimated that the requirement of pectin is nearly 20,000 tons all over the world with 15% growth every year.More than 1,500 tons of pectin is used in China,with 80% was depended on import.Development research on new method of production of pectin and the new resource of pectin are no...
