摘要
以黑果枸杞发酵后的皮渣为材料,采用酶解法,研究了其花色苷的最佳提取工艺条件。结果表明,黑果枸杞酒渣中所提花色苷在可见光范围内的最大吸收波长为525nm,最适酶为果胶酶,最佳提取条件为以pH1.0的蒸馏水为浸提剂,按料水比1:40(g:mL),加酶量0.8%,在50℃下,酶解提取60min,在此条件下,色价为7.903。
The anthocyanin extraction conditions from leather pomace of Lycium ruthenicum Murr.rosacea.after fermentation were optimized by using enzyme solution.The results showed that the maximum absorption wavelength of the anthocyanin was 525 nm,the optimal enzyme was pectic enzyme,the optimum conditions of the extraction were as follows：pH1.0 of distilled water to soak mention agent,the ratio of dry pomace to extracting solution 1：40（g：mL）,enzyme quantity 0.8%,extracting 60 min,below 50 ℃,in these conditions,produce was 7.903.
