臭氧水清洗结合气调包装对鲜切杭白菜保鲜效果的研究

以1.8mg/L臭氧水清洗的鲜切杭白菜为试验材料,研究不同气体组分的气调包装(CK为空气;A为5%O_2+5%CO_2+90%N_2;B为5%O_2+10%CO_2+85%N_2;C为10%O_2+5%CO_2+85%N_2;D为10%O_2+10%CO_2+80%N_2)对鲜切杭白菜保鲜效果的影响。结果表明:B组低氧高二氧化碳的包装能有效地抑制鲜切杭白菜上微生物的生长,保持其较好的感官品质,同时延缓VC、叶绿素及可溶性固形物含量的降低,防止杭白菜过快失水,有效地保证鲜切杭白菜的货架期在15d以上。

Effect of ozone water combined with modified atmosphere packaging on preservation of fresh-cut Hang cabbage

Fresh-cut hang cabbage cleaned by 1.8 mg/L ozone water was selected as the experimental material, the effect of keeping fresh on fresh-cut Hang cabbage was studied by different gas composition modified atmosphere packages, such as CK for air, A for 5% O₂+ 5% CO₂ +90% N₂, B for 5% O₂+10% CO₂+85% N₂, C for 10% O₂+5% CO₂+85% N₂, D for 10% O₂+10% CO₂+80% N₂. It showed that the 5% O₂+10% CO₂+85% N₂, low oxygen and high carbon dioxide packaging could effectively inhibit the growth of microorganisms, keep good sensory quality, and delayed the decreasing of vitamin C, chlorophyll and soluble solids content, prevented the cabbage excessive water loss, which effectively guaranteed the shelf life of fresh-cut Hang cabbage to more than 15 d.
