摘  要：
采用不同剂型及包装形式、不同扎眼工艺、放置高分子吸水纸垫及其组合,形成6种保鲜处理方式,在-1~0℃条件下对无核白葡萄进行贮藏,研究贮藏期间不同保鲜剂组合对袋内SO2积累量及无核白葡萄保鲜品质的影响,比较不同剂型保鲜剂及其组合对果肉SO2残留量、果柄耐拉力、果实汁液p H值、可溶性固形物含量以及果实腐烂率、漂白率、落粒率的影响。结果表明:3.5 kg包装的无核白葡萄,放入CT2号保鲜剂5小包+免扎眼保鲜剂1小包效果最好,在贮藏50 d后,果柄耐拉力为2.44 N,果实汁液p H值为3.43,可溶性固形物含量为17.16%,在贮藏105 d后,果肉SO2残留量为10.21 mg/kg,残留量明显低于其他处理,且腐烂率、漂白率、落粒率均较低。

摘  要：
The effects of six different combinations of preservatives on SO2 accumulation in packaging bags and quality preservation of Thompson seedless grape during-1–0 ℃ storage were compared by determining their SO2 residue, stem attachment, juice p H,soluble solid content, decay rate, bleaching rate and expulsion rate. The results indicated that 3.5 kg of Thompson seedless grape packaged with five bags of CT2 preservative and one unpierced bag of preservative(food-grade sodium metabisulfite and filler) had the best storage quality. After 50 days of storage, the attachment of stem, p H and soluble solid content were 2.44 N, 3.43 and 17.16%, respectively. The SO2 residue after 105 days of storage was 10.21 mg/kg, which exhibited a prominent decrease when compared with all other treatment groups. Moreover, the decay rate, bleaching rate and expulsion rate were also lower.
