Embodiment Construction

[0011] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0012] A kind of fresh red jujube fresh-keeping process of the present invention, it comprises the following steps:

[0013] 1. Picking requirements: The fresh jujubes that are to be stored for a long time must be manually picked. After picking, it is best to put them directly into the picking turnover box. The fresh jujubes that are picked and boxed should be full of fruits, bright in color, and the maturity should be controlled at 80% %-90% green-headed or half-red and half-green are the best, avoid packing rotten fruit, damaged fruit, moth-eaten fruit, deformed fruit, and fallen fruit. The fresh jujubes that are picked and put into the box should be stored in a shaded and ventilated field temporarily to avoid su...

Abstract

The present invention discloses a fresh-keeping technology for fresh-eating red jujubes. The fresh-keeping technology comprises the following steps: (1) carrying out artificial hand picking of fresh red jujubes, then directly loading the fresh red jujubes into picking containers, and the picked and cased fresh red jujubes have characteristics of being completely filled and bright in color, and having a mature degree controlled at 80%-90% and green or red-and-green heads; (2) reducing the temperature of a storage room to 1 DEG C before pre-cooling the fresh red jujubes and keeping the temperature of the storage room in pre-cooling at 1 DEG C, carrying out disinfection and sterilization on the fresh red jujubes after the pre-cooling storage room is fully filled; (3) pouring the sterilized fresh red jujubes into long-term storage plastic boxes, and keeping the weight of each plastic box at 5kg-10kg; pushing the plastic boxes loaded with the fresh red jujube boxes into a constant temperature cold storage and carrying out standard stacking; setting the temperature of the constant temperature cold storage at 0 DEG C after the cold storage is fully filled; spraying an aqueous solution of potassium permanganate on ground; reducing the temperature of the constant temperature cold storage by 0.2 DEG C every other day; and spraying the aqueous solution of potassium permanganate on the ground every one week, and carrying out fumigation and disinfection by a fresh red jujube fresh-keeping aerosol in the constant temperature cold storage every 10 days. The fresh red jujube fresh-keeping technology can extend the effective shelf life of the fresh red jujubes to 4-6 months.
