| 摘 要： | 采用HPLC和SDS-PAGE以及GC等技术分析了贮藏120 d后的果汁沉淀物的成分,沉淀物中酚类物质和蛋白质的性质。结果表明:果汁沉淀物以蛋白质为主,还含有碳水化合物、酚类(表儿茶素、绿原酸、单宁等)、5-羟甲基糠醛(5-HMF)等Vc降解产物,成分很复杂。沉淀物主要是由果汁中原有的颗粒聚集长大下沉产生。

| Abstract: | Sediment composition,phenolic compound and protein characteristics in sediment of cloudy apple juice were analyzed after 120 day storage by HCLP,SDS-PAGE and GC analysis techniques.Result showed that the sediment was complicated and mainly consisted of protein.It also contained degradation products of Vc as carbohydrate,phenolic compounds(epicatechin,chlorogenic acid,tannin) and 5-hydroxymethyl-furaldehyde(5-HMF).The sediment was mainly formed by the assembling of original particles in juice |
