Problems solved by technology

[0003] The existing processing methods of chestnut cooking are generally steaming or frying. The chestnut shelling process obtained by steaming or frying is inconvenient and does not meet the needs of modern fast-paced life. Some businesses also take out the cooked chestnut kernels. And compressed into chestnut bricks to be eaten, but this way of compression processing will destroy the natural shape of chestnuts and affect the eating experience

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] A kind of quick-frozen chestnut processing technology, comprises the steps:

[0031] Step 1: testing fresh chestnuts, the testing items are: chlordane, deltamethrin, beta-deltamethrin, and carbendazim. The required quality scores are as follows:

[0032] Chlordane: ≤0.02mg / kg, cypermethrin ≤0.01mg / kg, carbendazim ≤0.1mg / kg.

[0033] Step 2, putting the fresh chestnuts that pass the test into the cold storage for storage.

[0034] The temperature and humidity range of the cold storage environment is set at 0°C ± 2°C, and the humidity is ≥80%. The day before the chestnut raw materials are put into storage, the temperature of the cold storage should be set to -5°C, and the temperature of the cold storage should be monitored to prevent the chestnuts from becoming moldy and deteriorating due to excessive temperature.

[0035] Step 3: Take out the fresh ...

Abstract

The invention relates to a processing technology of quick-frozen chestnut kernels. The processing technology comprises the following steps of performing scratching to obtain openings, performing stir-frying, performing quick temperature reduction, performing peeling, performing cleaning and cooling, and performing quick-freezing, which are sequentially performed, wherein the stir-frying conditionis set as follows: the temperature is 230-280 DEG C and the time is 35-45min; in the stir-frying process, a manner of mixing and stir-frying Chinese chestnuts and sand is adopted, before stir-fried, the Chinese chestnuts need to be wrapped with a layer of malt sugar, and after the Chinese chestnuts are stir-fried, the Chinese chestnuts are separated from the sand through a sieve; and the quick temperature reduction condition is set as follows: the temperature is minus 30 to minus 20 DEG C, and the time is 30-40s. Through the technical scheme, the chestnut kernels can be processed, and naturalcharacteristics of the chestnut kernels can be completely stored, so that the processing technology can be suitable for needs for modern quick-rhythm life.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a quick-frozen chestnut processing technology. Background technique [0002] Chestnuts are a common and well-loved agricultural product. [0003] The existing processing methods of chestnut cooking are generally steaming or frying. The chestnut shelling process obtained by steaming or frying is inconvenient and does not meet the needs of modern fast-paced life. Some businesses also take out the cooked chestnut kernels. And compressed into chestnut bricks to be eaten, but this compression processing method will destroy the natural shape of chestnuts and affect the eating experience. Therefore, it is an urgent problem to be solved to provide a chestnut product processing technique that does not need to be shelled and obtains chestnut kernels that are relatively complete. Contents of the invention [0004] The object of the present invention is to provide...
