沙棘(h.ppoph.e r.0}mnoids L.),属于胡颓子属,在印度喜马偕尔邦地区称作"Ch.ar.a and Sur.h.,沙棘能够在这种非常恶劣的气候条件下自然生长。本文介绍了制作沙棘饮料的一系列程序和如何储存饮料120d而不使其变质的方法。沙棘果实采自印度喜马偕尔邦河谷。用碎浆机提取沙棘汁,制作沙棘饮料要准备好合适比例的沙棘汁和制作饮料所需的糖。随着果浆比例的升高,维生素C的含量明显增加(P≤0.05),随着贮藏时间的延长,维生素C的含量明显降低。而随着糖和果浆的增加以及储存期的延长,还原性糖呈上升趋势。当饮料中果浆和糖的比例分别为10%和13%、12.5%和13%、15%和15%时,饮料最为宜口,给于较高的评价。在喜马偕尔邦,人们一直认为沙棘具有商业价值,但是其价值在此前一直没有得到足够的重视。
