| 目的 以微环境气调箱为载体，将蓄冷剂应用于葡萄模拟物流中，研究其作用效果。方法 以“阳光玫瑰”葡萄为实验材料，于冷库中气调保存，分别在预冷24 h(记为0 d)和30 d时取出放入蓄冷剂，记为微环境气调箱(Microenvironment modified atmosphere packaging，mMAP)+蓄冷剂组，不加入蓄冷剂的记为mMAP组作为对照，研究在3 d常温((25±1)℃)模拟物流过程中蓄冷剂的加入对微环境气调箱内温度及葡萄果实感官品质、营养品质、色泽、硬度的影响，采用主成分得分分析对2组葡萄状态进行打分，再以生理指标和酶活性的变化规律分析蓄冷剂的加入对模拟物流过程中葡萄的影响。 结果 mMAP+蓄冷剂组箱内温度可低于mMAP组1~2 ℃，且mMAP+蓄冷剂组果实感官品质更佳，腐烂率、脱粒率及果梗褐变率更低，好果率更高，(30+3)d时可高于mMAP组12.61%，可溶性固形物、可滴定酸、VC、叶绿素等营养物质流失速度更慢，色泽变化更小，硬度较高，主成分得分分析结果为mMAP+蓄冷剂组＞mMAP组，且加入蓄冷剂后物流的果实相对电导率更低，呼吸作用及乙烯释放速率更弱，过氧化物酶活性更高，多酚氧化酶活性更低。结论 蓄冷剂的加入可有效维持葡萄模拟物流过程中的品质，并可使0 d常温采后物流时长延至3 d，30 d常温采后物流时长延至2 d。 |

| This paper aims to study the effect of cool-storage agent applied to grape simulated logistics using the micro-environment modified atmosphere packagings as the carrier. Taking the Shine-Muscat grape as the test material, it was stored in a cold storage and taken out at precooled for 24 h (0 d) and refrigerated for 30 d, respectively. Packagings with cool-storage agent were recorded as Microenvironment modified atmosphere packaging (mMAP) + cool-storage agent group, and those without cool-storage agent were recorded as mMAP group as control. The effect of the addition of cold-storage agents on the temperature and the sensory quality, nutritional quality, color and hardness of the grapes in the microenvironmental air conditioning chamber during the simulated logistics process at room temperature (25±1)℃ for 3 d. The grape state under different logistics conditions was scored by principal component score analysis, and then the effects of cold-storage agent on grape during simulated logistics were analyzed through physiological indexes and enzyme activities. The results showed that the temperature in the packagings of mMAP+cool-storage agent group was 1-2 ℃ lower than which of mMAP group. The sensory quality of grape of mMAP+cool-storage agent group was better, the decay rate, threshing rate and browning rate of fruit stalk were lower, and the rate of good fruit was higher, which could be 12.61% higher than that of mMAP group on (30+3)d. The nutrient quality such as soluble solids, titratable acid, VC, and chlorophyll were lost more slowly, the color change was smaller, the hardness was higher, and the principal component score analysis result was mMAP+cool-storage agent group > mMAP group. And after adding cool-storage agent, the relative conductivity was lower, the respiration and ethylene release rate were weaker, the peroxidase activity was higher, and the polyphenol oxidase activity was lower. Therefore, the quality of grape during simulated logistics process can be effectively maintained by adding cold-storage agent, the logistics time after harvest can be extended 3 d at normal temperature and the logistics time after storge 30 d could be extended 2 d at normal temperature. |
