Problems solved by technology

On the other hand, as the saying goes, the traditional freezing method takes a long time to save but requires a lot of equipment, and the persimmons will soften naturally during the cold storage method, so it is not suitable as a raw material for processing persimmon products
None of the methods can independently solve the problem that persimmons need a long shelf life and moderate softening to meet market sales

Embodiment 1

[0028] Take ripe persimmons, classify them, classify them, and clean them; then go through the alcohol method to remove the astringency, stack and spray them in layers during treatment, and keep them at room temperature for 3-5 days; then pack them into small boxes one by one, 20 small boxes per pack One box; send the box to the freezer, freeze it at -25°C for 24 hours, then transfer it to -10°C to -20°C for long-term storage, and move it into a refrigerator for sale before retailing. The temperature of the freezer is controlled at the freezing point of persimmons. -2°C.

Embodiment 2

[0030] Take a kind of persimmon, as in the method of Example 1, classify and screen, clean, use the mixed packing method to remove the astringency, mix an appropriate amount of apples in the persimmon pile, seal and stack for 10-20 days; then pack it in a small box, every 30 Put in a box; send it to the cold storage, freeze it at -25°C for 24 hours, then transfer it to -10°C ~ -20°C for long-term storage, and move it into a refrigerator for sale before retailing. The temperature range of the freezer for sale is adjusted at - 2 ℃ ~ -5 ℃, sold with a small spoon, immediately edible.

Embodiment 3

[0032] As in the method of Example 1, use lime water instead to immerse and sterilize, remove astringency, rinse, rinse, cool and dry, pack them into boxes one by one, freeze them quickly and then transfer them to frozen storage; before putting them on the market, move the frozen persimmons that have been stored for a long time into a refrigerated truck without thawing Transshipment, directly distributed to the general cold storage in various markets for storage, and then delivered to the cold storage of the distribution retail point and direct sales supply.

Abstract

A freeze storage method for persimmon when retail includes such steps as preparing raw materials, removing puckery taste, packing, quick freezing at -25 deg.C, and storing at -10- -20 deg.C for a long time. It can be directly eaten.

Description

technical field [0001] The invention relates to freezing, cooling and refrigeration. Specifically, it is a method of freezing and cold-storing fresh-keeping through the whole process in the later stage, so as to realize the cross-regional and cross-season marketing of persimmons for retail sales and direct consumption. Background technique [0002] Previously, in the persimmon storage method disclosed in Chinese Patent No. 93116514.8, a method was proposed to maintain the hard and crisp taste of persimmons, make the persimmons no longer astringent after processing, and extend the storage period to 200 days. On the other hand, as the saying goes, the traditional freezing method has a long storage time but requires a lot of equipment, and the persimmons will soften naturally during the cold storage method, so it is not suitable as a raw material for processing persimmon products. None of the methods can independently solve the problem that persim...
