Problems solved by technology

Due to the low moisture content of this kind of persimmon, it does not need to be refrigerated and can be stored for several months at room temperature; With the improvement of requirements, the white persimmon frost attached to the surface of persimmons is easily regarded as a dirty substance. Before eating persimmons, peo

Embodiment 1

[0026] 1) Processing of persimmons: select 7-point mature fresh persimmons that are free of diseases and insect pests, no rot, and no scars, clean them, peel them, and place them in a persimmon sieve. Dry them at 32°C for 7 days. Manually knead 3 times, and then use 50g / m 3 Perform sulfur fumigation for 10 minutes with the same amount of sulfur and perform 2 sterilizations;

[0027] 2) Quick freezing: Quickly freeze the processed dried persimmons in an environment of -35°C and a wind speed of 3m / s, so that the dried persimmons can pass through the -1~-5°C ice crystal formation zone within 20 minutes;

[0028] 3) Storage: Transfer the quick-frozen dried persimmons to a cold storage at -12°C for storage;

[0029] 4) Transportation: Use a refrigerated and insulated truck that can maintain -18°C to transport persimmons, and the loading and unloading time of persimmons is controlled within 1 hour;

[0030] 5) Sales: Sell dried persimmons at a temperature of -22°C.

Embodiment 2

[0032] 1) Processing of persimmons: select 8 mature fresh persimmons that are free of diseases and insect pests, no rot, and no scars, clean them and put them into the deaeration tank, fill with carbon dioxide gas to make the carbon dioxide content in the deaeration tank reach 95% , Seal the astringent tank and remove the astringency for 25 hours; take out the astringent persimmons, wash them, peel them, and bake them in an environment of 58℃ for 12 hours. Bake in the environment for 10 hours, repeat 3 times; then use 50g / m 3Sulfur fumigation for 5 minutes for sterilization, and the number of sterilization is 2 times; the sterilized persimmons are packed into 500g / bag with a packaging bag made of antifreeze composite plastic;

[0033] 2) Quick freezing: Quickly freeze the processed dried persimmons in an environment of -30°C and a wind speed of 5m / s, so that the dried persimmons can pass through the -1~-5°C ice crystal formation zone within 30 minutes;

[0034] 3) Storage: Transfe...

Embodiment 3

[0038] 1) Processing of persimmons: select 8 mature fresh persimmons that are free from pests and diseases, no rot, and no scars, clean them and put them in a solution of 10:1 water and quicklime, soak for 3 days, take out the water for the persimmons After washing and peeling, they are placed in a sieve for dried persimmons and dried at 10°C for 25 days. During the drying, the persimmons are manually kneaded once every two days, and then the weight is 50g / m. 3 Sulphur fumigation for 10 minutes;

[0039] 2) Quick freezing: Quickly freeze the processed dried persimmons in an environment of -32°C and a wind speed of 4m / s, so that the dried persimmons can pass through the -1~-5°C ice crystal formation zone within 10 minutes;

[0040] 3) Storage: Transfer the quick-frozen dried persimmons to a cold storage at -18°C for storage;

[0041] 4) Transportation: Use a refrigerated and insulated truck that can maintain -18°C to transport persimmons, and the loading and unloading time of persi...

Abstract

The invention discloses a dried persimmon and a cold chain treatment method for making the dried persimmon. The procedures are that: 1. processing of the dried persimmon: persimmons are processed into the dried persimmon of which water content is 28 to 43 percent; 2. quickly freeze: the processed dried persimmon is quickly frozen at the environment of temperature 30 to 35 DEG C below zero and wind speed 3 to 5 m/s; 3. storage: the quickly frozen dried persimmon is stored under the environment temperature of 12 to 22 DEG C below zero; 4. transport: the dried persimmon is transported under the environment temperature of 18 to 15 DEG C below zero; 5. sale: the dried persimmon is sold under the environment temperature of 12 to 22 DEG C below zero. The water content of the dried persimmon made according to the cold chain treatment method is kept between 28 to 43 percent, as a result of which the dried persimmon has a beautiful shape, does not have or only have little evenly distributed powder on the surface and has soft texture, the dried persimmon fresh is delicious and has a special taste and acerbity back rate is extremely low; in addition, under the freezing condition of temperature 18 to 22 DEG C below zero and humidity 85 to 95percent, the dried persimmon containing high water content has more than one-year guarantee period.

Description

(1) Technical field: [0001] The invention relates to a kind of food, in particular to dried persimmons. The invention also relates to a cold chain processing method of dried persimmons. (2) Background technology: [0002] Persimmon is a special product of our country, and its output accounts for 70 to 80% of the world's. Except for our country, only a few countries such as Japan and South Korea grow it. As a kind of high-quality and nutritious fruit, persimmon is deeply loved by people. However, the persimmon itself is easy to become soft, perishable, difficult to store, long-distance transportation, and short-lived, which restricts the sales and development of persimmons. In order to solve this problem, many producing areas implement deep processing of persimmons. For example, the application number is: 200510096238.x, and the Chinese invention patent named "A method for preparing persimmon freeze-dried superfine powder" uses vacuum freeze-drying and dehydration technology.
