摘要
为研究运输方式对生菜采后生理及保鲜效果的影响,以‘橡生2号’生菜为研究对象,选择3种常见的运输方式:保温箱包装常温运输(A)、保温箱加制冷剂包装在常温下运输(B)、PE包装袋加纸箱包装在0℃下运输(C)进行试验。结果表明,采用C方式在0℃冷藏条件下运输的生菜,其失重率和呼吸强度均低于另外2组,VC含量和感官评价高于另外2组。因此在运输时间在12 h内可以采用A方式运输,在24 h内可以采用B方式运输,如超过24 h则最好使用C方式运输来保证生菜的货架期及品质。
To study the effects of transportation modes on physiology and preservation of postharvest lettuce,‘Xiangsheng No.2＇was selected as the research object. The transportation experiments were carried out using three transportation modes： warm box packaging and transporting at room temperature（A）, warm box addingrefrigerant packaging and transporting at room temperature（B）, PE bag and carton packaging and transportingat 0℃（C）. Results showed that weight loss ratio and respiratory intensity of mode C were lower than that of theother two groups, and VC content and sensory evaluation value were higher than that of the other 2 groups. Somode A, B, C was more suitable when transportation time was within 12 h, 12- 24 h and more than 24 h,respectively.
