Effects of pre-treatments of white mushrooms prior to modified atmosphere packaging on their physico-chemical and microbiological properties were studied during 12 days of storage at 4 °C. Physico-chemical and microbiological properties of differently treated mushrooms stored at 4 °C were significantly different (P < 0.05) from untreated ones. Washed samples exhibited the smallest respiration rate compared to all other samples. Hydrogen peroxide washing was effective in retaining mushrooms colour change. Furthermore, the diminishments in weight of ultrasound treated samples during storage were significantly (P < 0.05) low in comparison with the other four treatments. The weight loss for ultrasound treated samples were 3.52 %, 4.07 % and 4.59 % for Uca, UH2O2 and UH2O respectively. The lowest PPO activity was observed in Uca, UH2O2 followed by Wca, WH2O2, UH2O and WH2O treatments respectfully. Combined treatments showed lower polyphenol oxidase activity, retained antioxidants, delayed pseudomonas growth and did not cause any decline in tissue firmness during storage time implying that it could extend shelf life of white mushrooms up to 12 days at 4 °C.
研究了气调包装前白蘑菇预处理对其在4℃储存12天期间理化和微生物特性的影响。4℃储存的不同处理蘑菇的理化和微生物特性与未处理的蘑菇有显著差异（P<0.05）。与所有其他样品相比，水洗样品的呼吸速率最小。过氧化氢洗涤有效地抑制了蘑菇颜色的变化。此外，与其他四种处理相比，超声处理样品在储存期间的重量减少显著（P<0.05）较低。超声处理的Uca、UH2O2和UH2O样品的重量损失分别为3.52%、4.07%和4.59%。分别在Uca、UH2O2处理中观察到最低的多酚氧化酶活性，其次是Wca、WH2O2、UH2O和WH2O处理。联合处理显示多酚氧化酶活性较低，保留了抗氧化剂，延迟了假单胞菌的生长，并且在储存期间没有导致组织硬度下降，这意味着它可以将白蘑菇在4℃下的货架期延长至12天。
