茶饼中茶皂素的提取和微量元素的测定

Extraction of saponin and determination of trace elements in camellia cake

摘要: 茶饼经过浸提，可以提出茶皂素和残油，提取率分别为１１．０％和５．０％．然后经过发酵可制得蛋白饲料，对饲料中蛋白质和１０种微量元素进行了分析测定．结果表明，蛋白质含量为９．６８％，Ｍｇ、Ｆｅ、Ｃａ、Ｍｎ、Ｚｎ、Ｃｕ元素含量较为丰富．

Abstract: Saponin and residual oil can be extracted from camellia cake and recovery rate are 11.0% and 5.0%, respectively. Camellia cake can be further turned into protein forage by fermentation. Content of protein and ten trace elements in forage were determined. The results show that the forage contains 9.68% protein and higher amount of Mg,Ca,Fe,Mn,Zn,Cu than other elements. Saponin and residual oil can be extracted from camellia cake and recovery rate are 11.0% and 5.0%, respectively. Camellia cake can be fur...
