中文摘要: 论黑加仑果汁加工前后果渣中脂肪酸、原花青素、多糖、维生素 C、金属离子含量的变化,为果渣综合开发提供 理论支持。采用 GC 柱前衍生法讨论加工前后脂肪酸含量变化,国标检测其它成分。结果显示:果渣 16 种主要脂肪酸加 工前后变化较小;原花青素、多糖和维生素 C,分别为(0.50±0.13)%,(1.57±0.28)%及(62.4±6.74)mg/100 g;钾、钙迁移率 达到 40 %以上;砷、镉、铅、铬存在一定迁移风险。
Abstract:To provide theoretical su pport for the marc's comprehensive development. Fatty acids, procyani- dine, polysaccharides, vitamin C and metal ion content's were discussed. The fatty acids can be determined with pre -column derivatization by gas chromatography .Using national food sanitary standards, study on the chances of Compositions in the Marc; the results showed that: the changes of 16 main fatty acids in marc were smaller. Procyanidine was(0.50±0.13) %, polysaccharide was(1.57±0.28) %, and vitamin C was(62.4±6.74) mg/100 g. The mobilization rate of K and Ca was more than 40 %. There was a certain risk migration about As, Cd, Pb, Cr.
