Abstract Although cantaloupes are extremely popular fruits, they are prone to easy decay and present potential vehicles for foodborne disease transmission. This study examined the effects of different doses of ozone treatments on the postharvest quality of cantaloupes during storage. These results revealed that cantaloupe subjected to the appropriate dose of ozone (15.008 mg m−3) displayed lower respiration rate, ethylene production rate, and the number of microorganisms, as well as higher levels of firmness, pectin content, reducing sugar and titratable acidity of both the sarcocarp and exocarp. Next-generation sequencing results showed that this particular ozone dose inhibited most genera responsible for cantaloupe decay and human pathogenicity to a certain extent. Principal component analysis, as well as the analysis of co-occurrence network patterns further confirmed that an ozone dose of 15.008 mg m−3, improved and prolonged the postharvest quality of cantaloupe.

不同剂量臭氧处理对哈密瓜采后品质和生物多样性的影响

摘要 虽然哈密瓜是非常受欢迎的水果，但它们容易腐烂，是食源性疾病传播的潜在载体。本研究考察了不同剂量的臭氧处理对贮藏期间哈密瓜采后品质的影响。这些结果表明，经过适当剂量臭氧（15.008 mg m-3）处理的哈密瓜表现出较低的呼吸率、乙烯产生率和微生物数量，以及较高的硬度、果胶含量、还原糖和可滴定酸度肉果皮和外果皮。下一代测序结果表明，这种特殊的臭氧剂量在一定程度上抑制了大多数负责哈密瓜腐烂和人类致病性的属。主成分分析，
