不同保鲜包装方式对菜心品质的影响

Effects of Different Packaging Methods for Preservation on the Quality of Chinese Flowering Cabbages

  • 摘要: 为了考察不同保鲜包装方式对菜心品质的影响,采用厨房纸巾包装(ZJ)、普通塑料保鲜袋(CPE)、气调保鲜袋(EFB、JG)保鲜菜心,以不做任何保鲜处理的菜心为对照(CK),分别在常温(18~23 ℃)和低温(4~6 ℃)下贮藏5和25 d,评价菜心的外观商品性、腐烂率、黄化率、失重率、叶绿素、水分、可溶性糖和维生素C含量的变化。结果表明:气调保鲜袋(EFB、JG)包装的保鲜效果优于CPE和CK,ZJ最差。较于其它包装方式,EFB和JG处理的菜心外观商品性更高,保持较高的营养品质。其中JG对菜心保鲜效果最佳,低温贮藏25 d时腐烂率为0.03%,黄化率为0.42%,失重率为1.55%,叶绿素含量降低幅度为5.01%,水分下降幅度为1.26%;低温贮藏15 d时,可溶性糖含量与第1 d无显著差异(P>0.05),维生素C含量降低幅度为11.43%,显著低于其它包装处理(P<0.05)。综上,低温配合气调保鲜袋贮藏能延长菜心保鲜期,是一种较好的菜心贮藏保鲜方法。

     

    Abstract: To investigate the effects of different packaging methods for preservation on the quality of Chinese flowering cabbages, kitchen towel (ZJ), common plastic bags (CPE), and modified atmosphere bags (EFB and JG) were used to keep them fresh, with untreated ones as the control (CK). The Chinese flowering cabbages were stored at room temperature (18~23 ℃) or low temperature (4~6 ℃) for 5 days and 25 days, respectively. Then, they were evaluated for commerciality in appearance, rotting rate, etiolation rate, weight loss, and changes in the content of chlorophyll, water, soluble sugar and vitamin C. The results showed that the fresh-keeping effect of modified atmosphere bags (EFB and JG) was better than that of CPE and CK, and ZJ exhibited the worst effect. Compared with other methods, Chinese flowering cabbages packed with EFB and JG showed higher commerciality in appearance and maintain higher nutritional quality. Among them, JG had an even better fresh-keeping effect, with a rotting rate of 0.03%, an etiolation rate of 0.42%, a weight loss of 1.55%, and a minor decrease in chlorophyll content and water content (5.01% and 1.26%, respectively) after 25 days of low temperature storage; on the other hand, when compared with day 1, there was no significant difference in the content of soluble sugar after 15 days of low temperature storage (P>0.05). In addition, the content of vitamin C only decreased by 11.43%, a value significantly lower than that of any other methods (P<0.05). To sum up, the storage under low temperature with modified atmosphere bags can prolong the freshness lifetime of Chinese flowering cabbages, which is ideal for their storage and preservation.
