Problems solved by technology

This patent does not carry out the microbial control in the early stage of bacteria reduction process and processing, which may cause the number of microorganisms to exceed the standard, and the safety of the product is relatively poor
Because green onions are sometimes eaten raw or mixed with cold dishes, if the microorganisms exceed the standard, it will cause serious consequences of food poisoning
In addition, the raw material cleaning method adopted in this patent is too crude, which will inevitably leave a hygienic corner, thereby failing to meet the hygienic standard of instant food
Finally, the quick-freezing method of this patent also has certain limitations. It is to place the green onions in a -28°C freezer for 2 hours, or send them to a -35°C freezer for 1.5 hours, but there is a shortcoming, that is, the longer the freeze time Longer, the more serious the off-flavor of the onion, the greater the possibility of microbial contamination, resulting in a decline in quality and poor taste

Abstract

The invention discloses a processing method of scallion, which comprises the following steps that: prewashing; first-time dipping sterilization; fine washing; second-time dipping sterilization; segmentizing; third-time dipping sterilization; pre-cooling in ice water; and quick freeze, so a finished product is obtained. Due to adoption of the processing method, the hygiene and safety problem of the scallion can be well solved, thorough removal of impurities, thorough decontamination and thorough removal of residual sterilizing agent of raw materials can be guaranteed; and pollution of microorganisms on the scallion can be maximally reduced, and the taste of the scallion can be maximally maintained.

Description

technical field [0001] The invention relates to a processing technology of agricultural products, in particular to a processing method of green onions. Background technique [0002] Onion is a perennial herb with green onion leaves on the upper part and white onion white on the lower part. Onion is not only a common seasoning, but also a delicacy. The main nutrients of onion are protein, sugar, dietary fiber, phosphorus, iron, magnesium and other minerals. Onions are rich in allyl sulfide, vitamin C and calcium.
