摘要:

研究不同厚度塑膜贮藏果蔗的质构特性和生理特性变化,为甘蔗贮藏保鲜提供一定理论基础。本研究以‘拔地拉’为试材,分别采用室温、室温+0.02 mm塑膜和室温+0.10 mm塑膜3种方式贮藏,测定果蔗在贮藏过程中硬度、可溶性固形物(TSS)、可滴定酸、维生素C、失重率等的变化以及蔗茎开裂、果肉褐变与霉变情况。结果表明,在贮藏前6周,室温+0.02 mm塑膜和室温+0.10 mm塑膜处理果蔗的硬度、可溶性固形物、Vc、失重率等下降缓慢,可滴定酸含量上升较缓,贮藏品质较好,但贮藏6周后,这2种处理的果蔗品质下降较快;在整个贮藏期内塑膜处理的果肉褐变速度较缓;至贮藏12周时,3种处理开裂率分别为12.86%、5.71%和4.29%,但均未发现霉变和芽点萌动现象。综上,在较低的室温条件下,塑膜贮藏能够延缓果蔗衰老进程,但塑膜厚度对贮藏综合品质影响不大。

Abstract:

The changes of texture and physiological characteristics of sugarcane stored in plastic film with different thickness were studied to provide certain references for fresh-keeping of sugarcane. ‘Badila’ was used as the test material, the hardness, soluble solids (TSS), titratable acid, vitamin C, weight loss rate, stem cracking, pulp browning and mildew of sugarcane were determined in 3 storage ways, including room temperature, room temperature+ 0.02 mm plastic film and room temperature+ 0.10 mm plastic film. The results showed that the hardness, soluble solids, Vc and weight loss of sugarcane treated with room temperature+ 0.02 mm plastic film and 0.10 mm plastic film decreased slowly, titratable acid content increased slowly and the storage quality was relatively good in the first 6 weeks, then, the quality of sugarcane treated with these two ways declined rapidly; during the whole storage period, the pulp browning rate of the two treatments with plastic film was slow; and the cracking rate of the three treatments was 12.86%, 5.71% and 4.29%, respectively, at 12 weeks’ storage, but no mildew and bud germination were found. In conclusion, plastic film storage can delay the aging process of sugarcane at lower room temperature, but the thickness of the plastic film has little effect on the comprehensive quality of storage.

Key words: fruit sugarcane, storage, weightlessness rate, mildew, comprehensive quality
