摘要: 选用6种天然、无毒的试剂半胱氨酸(L-Cys)、食盐、柠檬酸(CA)、抗坏血酸(VC)、壳聚糖、植酸作为单一保鲜剂进行实验,在此基础上选取保鲜效果较好的4种试剂进行L9(34)正交优化试验,筛选出的复合保鲜剂配方为:L-半胱氨酸2.5g/L、柠檬酸8.0g/L、抗坏血酸0.5g/L、食盐6%。经此复合保鲜剂处理的香菇在10℃可保存15~16d,其效果好于单一保鲜剂和蒸馏水对照。贮藏期间气味、颜色正常,褐变度、失重率、细胞膜透性、呼吸强度等指标明显低于单一试剂和蒸馏水对照。

Abstract: Four preservatives with better preservation effects on Lentinus edodes were chosen from six natural and safe preservatives,namely L-cysteine,NaCl,citric acid(CA),vitamin C(VC),chitosan and phytic acid by single-factor test. Their optimal proportions are L-Cys 2.5 g/L,CA 8.0 g/L,VC 0.5 g/L and NaCl 6% by L9(34) orthogonal test. The complex preservative can extend the shelf life of L. edodes for 15 to 16 d at 10 ℃. This treatment can efficiently decrease the respiration rate,weight lose rate and cell membrane permeability of Lentinus edodes. Compared with the treatment of single-factor preservative or distilled water,the complex preservative has the best preservation effect on Lentinus edodes.
