采用海藻酸钠和壳聚糖涂膜处理并结合氩气气调,对鲜切香菇进行包装,检测了鲜切香菇在贮藏中的呼吸强度、失重率、硬度、白度、PPO 活性以及感官评定等指标,研究了不同配比复合液对鲜切香菇贮藏保鲜效果的影响。 结果表明,0. 5% 壳聚糖+1. 5% 海藻酸钠处理组,能有效地抑制鲜切香菇的呼吸速率和失重率,并维持最高的硬度值,且在贮藏后期,其白度值明显高于其他处理组,更易让消费者接受。

Fresh-cut lentinus edodes were coated with mixed solutions containing different concentrations of sodium alginate and chitosan, and then packaged with argon MAP. The effects of sodium alginate and chitosan concentration on the qualities of fresh-cut lentinus edodes were studied by measuring the respiration rate, weight loss rate, hardness, whiteness, PPO, and sensory evaluation. Results indicated that the 0. 5% chitosan +1. 5% sodium alginate can inhibit effectively the respiration rate and weight loss rate of fresh-cut lentinus edodes; it can also maintain the highest hardness value; and in the later storage period, the whiteness value is significantly higher than other treatment groups, so it is more acceptable for consumer.
