苹果采收后在贮藏过程中,常因病菌感染而造成腐烂。在普通土窖贮藏5～6个月后的苹果,有些品种烂果率可高达20～40％,经济损失极大。为了减少贮藏苹果因自然腐烂而造成损失,我们选用了化工部天津化工研究院研制的新型杀菌剂过碳酸钠(2Na_2CO_3·3H_2O_2)。过碳酸钠是一种无臭的白色粉末,为碱性的强氧化剂。遇水水解成碳酸盐和过氧化氢(双氧水)。过氧化氢在碱性条件下,进一步分解成水,并释放出活性氧。 Apple harvest in the storage process, often due to infection caused by bacteria decay. Apples stored in ordinary silos 5 to 6 months, some varieties of rotten fruit rate as high as 20 to 40%, great economic loss. In order to reduce the loss of stored apple due to natural decay, we selected 2Na_2CO_3 · 3H_2O_2, a new bactericide, developed by Tianjin Chemical Research Institute of Ministry of Chemical Industry. Sodium percarbonate is an odorless, white powder that is a basic, strong oxidizer. Water hydrolysis into carbonates and hydrogen peroxide (hydrogen peroxide). Hydrogen peroxide in alkaline conditions, further decomposition into water, and release of reactive oxygen species.
