摘 要: 以银杏种子为研究对象,以50℃热水为处理介质,研究了不同热激处理时间(0 5、1、1 5、2、2 5h)对常温贮藏期间银杏种子霉变的影响.对贮藏期间霉变率、多聚半乳醛酸酶(Polysalacturonase,PC)和果胶甲酯酶(Pectinesterase,PE)活性等指标进行了测定.结果表明,热激处理能有效地抑制银杏霉变,且在本实验处理时间范围内,抑制程度随热激处理时间延长而增加. The ginkgo ( Ginkgo biloba L.) seeds were treated with hot water (50℃) for different time (0.5, 1, 1.5, 2 and 2.5 h) and then stored at ambient temperature to study the influence of heat shock treatment on mildew. Mildew percentage, polysalacturonase(PG) and pectinesterase(PE) activities were measured during storage. The experiments showed that heat shock treatment refrained mildew, and the degree of refraining increased with the time of heat shock treatment.
