摘要
通过L9(3)4正交试验设计,研究了不同温度、包装材料、初始O2体积分数和CO2体积分数对双孢蘑菇主动气调包装中贮藏保鲜效果的影响。分别于贮藏后的第3 d、第5 d、第7 d、第9 d和第11 d测定各个试验处理双孢蘑菇的失重率、硬度、褐变度、呼吸速率、细胞膜透性、可溶性固形物、PPO活性和POD活性。试验结果表明:温度是影响双孢蘑菇贮藏品质的最重要因素,较低的贮藏温度有利于双孢蘑菇贮藏品质的保持;贮藏过程中能保持双孢蘑菇贮藏品质的较优处理组合为贮藏温度为2℃、包装材料为PVC2、O2和CO2体积分数分别为15%和10%。
An L9（3）4 orthogonal test was carried out to evaluate the storage quality of Agaricus bisporus under active modified atmosphere packaging with different temperature,packaging material,O2 and CO2 volumetric concentrations.Weight loss,fructification firmness,degree of browning,the respiration rate,membrane permeability,soluble solid content,polyphenoloxidase（PPO） and peroxidase（POD） activity of Agaricus bisporus were determined on the 3th day,5th day,7th day, 9th day,11th day after storage,respectively.Study results suggested that,storage temperature was the most important factor affecting the storage quality of Agaricus bisporus,and a low storage temperature was essential to the preservation of Agaricus bisporus;the optimum treatment of active modified atmosphere packaging for Agaricus bisporus was that storage temperature 2℃,packaging material PVC2,15% O2 volumetric concentration,10% CO2 volumetric concentration.
