Description
Technical Field
The invention relates to the technical field of aquatic product processing, in particular to an instant flavored aquatic product processing technology and equipment.
Background
The aquatic products (such as freshwater fish and the like) are rich in nutrition and delicious in taste, are deeply favored by people, and various processing modes of the aquatic products are promoted along with the pursuit of the diversity of the tastes of the foods by people, and the instant flavored aquatic products are one of the processing methods of the aquatic products. However, the instant flavor aquatic products on the market have heavy fishy smell or heavy spice smell, and the delicate flavor of the aquatic products is covered.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a processing technology and equipment for instant flavored aquatic products.
In order to achieve the above purpose, one of the technical schemes adopted by the invention is as follows: the processing technology of the instant flavored aquatic product comprises the following steps:
step 1), raw material pretreatment: removing the head and impurities of the purchased raw materials, and removing fishy lines if the aquatic products have fishy lines; and performing primary cleaning;
step 2), deodorization treatment: smearing a layer of thin salt on the whole body of the raw material treated in the step 1), smearing 50-65 degrees white spirit on the whole body of the raw material after 3-8min, and scraping mucus on the surface of the raw material by a scraper before smearing the white spirit on the whole body of the raw material;
the conventional deodorization method is to soak the pretreated raw materials after washing and the like in the prepared deodorization liquid to remove the fishy smell, and the deodorization liquid has large differentiation of deodorization effect due to the difference of the formula and the proportion of the deodorization liquid, and the deodorization liquid can enter the next working procedure after the surface of the deodorization liquid is dried after being soaked for a long time. According to the method, after the head and fishy line removal treatment in advance, the surface mucus is scraped after the salt is smeared, and the white spirit is smeared, so that the time consumption is short, the source of fishy smell substances on raw materials is removed from the source, and the fishy smell removal effect is relatively stable and good;
step 3), fresh-locking treatment before dicing: injecting the fresh-locking liquid which is prepared in advance and has the temperature of 10-25 ℃ into different parts of the raw material obtained through the treatment in the step 2), and then sending the fresh-locking liquid to be cut into blocks to obtain blocky aquatic products;
step 4), fresh-locking treatment after dicing: spraying a prepared fresh-locking liquid with the temperature of-2 to 4 ℃ into the blocky raw material treated in the step 3), and stirring the raw material while spraying;
in the processing of aquatic products, the raw materials are generally soaked in the pre-prepared fresh-locking liquid, in practice, a long time is required for the fresh-locking liquid to permeate into the raw materials, and in the soaking process, the raw materials are likely to lose water, so that the final product has excessive firewood taste. According to the method, the fresh-locking treatment is carried out by adopting an injection mode before dicing, and then the fresh-locking treatment is carried out after dicing and uniformly mixing with the fresh liquid, so that the fresh-locking liquid can be uniformly fed into the raw materials in a short time, the raw materials hardly lose water, and the consumption of the fresh-locking liquid is relatively low;
step 5), curing and mixing treatment: cleaning the raw materials obtained in the step 4) by flowing water, then sucking up obvious water marks on the surfaces of the raw materials by cotton gauze, frying the raw materials in a conventional mode until the two surfaces of the raw materials are golden and thoroughly cooked, and directly stirring the raw materials with seasonings without cooling;
and 6) vacuum packaging.
Preferably, the fresh-locking liquid in the step 3) is prepared from the following raw materials: polydextrose, lemon juice, food grade cysteine, food grade phosphate, and water; and based on 1kg of raw material, 5-8g of polydextrose, 10-100g of lemon juice, 0.001-0.01g of food-grade cysteine, 0.1-1g of food-grade phosphate and 20-100g of water are added.
Preferably, the step 5) is to apply flour or starch to the whole body of the raw material after the moisture on the surface of the raw material is absorbed, and then to fry the raw material.
