Problems solved by technology

[0004] The purpose of the present invention is to provide a pretreatment method for frozen aquatic products to solve the problem of simple cleaning in the early stage of freezing without corresponding sterilization treatment, resulting in insufficient fresh-keeping time and aquatic products being easily spoiled. Bacterial corrosion eventually leads to the problem of spoilage of aquatic products

Embodiment 1

[0026] see figure 1 , the present invention provides a technical solution: a pretreatment method for frozen aquatic products, specifically comprising the following steps:

[0027] S101. Raw material preparation and treatment, prepare 12% sodium chloride solution, ethanol, and some chitin raw materials, and then select the aquatic products that have just been salvaged to ensure the freshness of the aquatic products, and then remove the viscera and scales of the selected aquatic products Wait for the inedible parts, and soak in clean water at room temperature for 1 minute to remove most of the blood stains and residual impurities, and the raw materials are common in the market;

[0028] S102. Preliminary cleaning and pre-cooling. Take out the soaked aquatic products, and then place them in cold running water at 0 degrees Celsius to rinse for 3 minutes. Use cold water to further clean the aquatic products so that the aquatic products are completely cleaned. At the same time, use ...

Abstract

The invention discloses a pretreatment method for freezing and fresh-keeping of aquatic products. The pretreatment method specifically comprises the following steps of S101, preparing and treating raw materials: preparing a plurality of raw materials including a sodium chloride solution with the concentration of 12%, ethanol and chitin, then selecting the aquatic products which are just fished ashore to ensure the freshness of the aquatic products, then removing inedible parts such as viscera and scales from the selected aquatic products, and soaking the aquatic products in clean water at normal temperature for 1-3 minutes to remove most of bloodstains and residual impurities, wherein the raw materials are common in the market; and S102, performing preliminary cleaning and pre-cooling: taking out the soaked aquatic products, then placing the aquatic products in flowing cold water at the temperature of 0-3 DEG C to be flushed for 3-5 min, and further cleaning the aquatic products through the cold water, so that the aquatic products are completely cleaned. According to the method, a soaking solution is prevented from being polluted by using a sterile environment, so that the sterilization effect of the subsequent soaking solution on the aquatic products is improved; and the preservation time of the aquatic products is greatly prolonged through the cooperation of sterilization and later rapid freezing and vacuum packaging.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pretreatment method for frozen aquatic products. Background technique [0002] Cold storage generally refers to facilities that use various equipment to refrigerate, artificially control and maintain a stable low temperature; its basic components are: refrigeration system; electronic control device; warehouse with certain heat insulation performance; auxiliary buildings, etc.; aquatic product cold storage , by freezing or refrigerating for a long time to preserve the freshness of aquatic products. [0003] Generally, aquatic products only rely on cold storage for fresh-keeping treatment. In the early stage of freezing, only simple cleaning treatment is carried out, and there is no corresponding sterilization treatment, resulting in insufficient fresh-keeping time. Aquatic products are easily corroded by bacteria and eventually cause aquatic products to rot. method to solve the...
