胡萝卜粉的理化性质及其应用研究

本文对50目和300目两种颗粒大小的胡萝卜粉理化性质和它在面条与牛奶中的应用进行了研究。结果表明:300目胡萝卜粉与50目粉相比,其比表面积明显增大,溶解性有一定提高,粒度分布的中位径D50减少至20.0μm,颜色L、a、b值有所增加,但色调Hue没有改变。50目粉添加到面条中效果好,300目粉添加到牛奶中效果好。

Study on Physical and Chemical Properties of 50 Mesh and 100 Mesh Carrot Powder and Their Application

This report investigated respectively the physical and chemical properties of 50 mesh and 100 mesh carrot powderand their application in the processing of Chinese noodle and pasteurized milk. Compared with 50 mesh carrot powder, 300mesh carrot powder showed a sharp increase of specific surface area and dissolution, and a slight increase of L value, a value andb value, and an unchanged Hue angle, while its D50 in particle size distribution decreased to 20.0μm. In the preference organolepticevaluation, 50 mesh carrot powder was superior to 100 mesh carrot powder in the Chinese noodle, but inferior to 100 mesh carrotpowder in pasteurized milk.
