Abstract

The invention discloses a storage and fresh-keeping comprehensive treatment method for Huangguan pears. The comprehensive treatment method comprises seven steps of harvesting in the optimum period, calcium supplementing treatment, film coating treatment, 1-methylcycloproene treatment, packaging, pre-cooling and refrigerating; and the method comprises the steps of pre-cooling in the harvesting period and after the harvesting period as well as other treatment steps, all the steps are interlocked and indispensable, and the method has a good fresh-keeping effect. The method disclosed by the invention can effectively control the phenomena that the Huangguan pears are softened, wilted and decayed, and have superficial browning spots and thinned flavors, and the like in the process of storage, thereby facilitating the original flavor and quality of fruits.

Description

technical field [0001] The invention relates to a comprehensive treatment method for storage and preservation of Huangguan pears, belonging to the technical field of postharvest storage and processing of fruits. Background technique [0002] Huangguan pear is bred from the hybridization of snow pear and Japanese new century pear. The fruit is oval. When it is bagged in a dark bag or a multi-layer bag, the ripe fruit has a yellow skin and a smooth and rust-free surface.
