摘要: 采用厚度75.8μm的PP复合膜对番木瓜室温下气调保鲜包装的技术进行研究。结果表明:气调保鲜技术可以降低番木瓜失水率、减缓表面变黄速率、防止硬度下降、减少可溶性固形物含量、防止VC的大量损失。评定指标选用了硬度、色泽、失水率、VC含量、可溶性固形物、pH值、感官评定。结论得出:番木瓜气调保鲜包装的平衡气体浓度为O24.2%~4.9%,CO27.3%~7.9%;番木瓜气调保鲜包装内气体最佳初始浓度为3%O2、9%CO2、88%N2;测得室温下气调包装达到平衡时,番木瓜的呼吸强度为0.2~0.4ml/kg·hCO2。

Abstract: In this experiment, papayas were packed by 75.8μm PP compound film and stored at room temperature. This method can prevent loss of water, loss of VC and further loss of firmness and inhibit yellowing of papaya fruit. All detecting items for these samples were firmness, color, lose of water, VC, total soluble solids, pH and sensory assessment. The conclusions are: the balance gas concentrations of modified atmosphere packaging are O2 4.2%~4.9% and CO2 7.3%~7.9%. The optimum gas concentrations of modified atmosphere packaging are 3% O2, 9% CO2 and 88% N2. With modified atmosphere packaging , papaya’s CO2 production rate is 0.2~0.4 ml/kg·h CO2 at room temperature.
