不同包装处理对胡萝卜贮藏期间品质的影响

研究不同包装方式下的胡萝卜 (Daucus carota)在贮藏期间的品质变化,筛选出最佳的包装方式以有效延长胡萝卜的贮藏时间.结果表明,塑料箱加微孔膜与塑料箱加0.04 mm薄膜包装可有效减缓胡萝卜的失重率、糠心指数、颜色指数、游离氨基酸质量分数、粗纤维质量分数、总酚物质质量分数的升高,减缓可溶性蛋白质质量分数的降低,适合应用于胡萝卜的贮藏；塑料箱、纸箱、编织袋包装的胡萝卜品质下降明显,不适合用于胡萝卜的长期贮藏.

The Effect of Different Packings on Quality of Carrot during Storage

Effects of different packing methods on post-harvest storage quality and nutrient component of carrot were studied.The results showed that plastic box with microporous membrane and plastic box with 0.04 mm film packing could effectively relieve the increase of weightlessness rate,bran cardiac index,color index,free amino acids,crude fiber content,total phenolic content,while slowdown the decrease of soluble protein,thus they were suitable for carrots storage application.The qualities of carrot stored in plastic box,paper carton,plastic woven sack were significantly decreased,and these packings were not suitable for long-term storage of carrot.
