Abstract

The invention discloses a lucuma nervosa fruit fresh-keeping agent and a fresh-keeping method thereof, and belongs to the technical field of fruit and vegetable fresh keeping. The fresh-keeping agentcomprises an aqueous solution of sodium carboxymethyl cellulose and an additive, wherein the additive comprises the following raw materials in percentage by weight: based on 100% of the aqueous solution of sodium carboxymethyl cellulose, 2.0-4.0% of a galangal extract, 0.08-0.12% of marine organism lysozyme, 0.2-0.6% of thellungiella salina leaf total flavonoids and 0.05-0.20% of gallic acid. Thefresh-keeping time of lucuma nervosa fruits treated by the method is remarkably prolonged, and the lucuma nervosa fruits can be stored for 20 days or more at room temperature. According to the fresh-keeping method for prolonging the storage time of the fresh lucuma nervosa fruits, economic losses are greatly reduced, the fresh fruits are continuously provided for the market, the requirements of consumers can be met, the industrialization development of the lucuma nervosa fruits in China can be promoted, and besides, a reference method is provided for fresh keeping of other fruit products.

Description
