Problems solved by technology

In the pretreatment process of fish roe processing, there is a process of removing the mucus from the fish roe. The traditional method is to put the fish roe into a basin, add water and talcum powder, and rub the fish roe with hands to remove the mucus on the fish roe. The problem with this method is that it is difficult to control the force when rubbing, it is easy to damage the egg membrane, and the fingernails will also scratch the fish eggs
This method introduces exogenous additives, and carotene will cause the fish roe to turn yellow, which is not conducive to subsequent processing

Abstract

The invention discloses a physical method for debonding fish roes, and belongs to the technical field of aquatic food processing. According to the method, after fish roes are pretreated, primary debonding is conducted through echelon pulse intense light, then ozone water is added into the fish roes, and secondary debonding is conducted through the coupling effect of ultrasonic waves and the ozone water. The debonding effect of the fish roes is good, breakage of the fish roes is prevented, the fish roes are full, the chewing taste is crisp and elastic, and subsequent processing and utilization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of aquatic food processing, and in particular relates to a physical method for debonding fish roe. Background technique [0002] Fish roe is a nutrient-rich food, which contains a lot of protein, calcium, phosphorus, iron, vitamins and riboflavin, and very low cholesterol content. It is a good nourisher for the human brain and bone marrow, especially for children and adolescents. It is very important for the development of human body, not only can promote the body to grow taller, the body is fit, but also can strengthen the brain and intelligence, make people think quickly, and is extremely beneficial to human health. [0003] In recent years, with the improvement of residents' consumption level, fish roe products have gradually entered the people's dining table. Because of its delicious taste and rich nutrition, consumers have paid more and more attention to the nutritional and medicinal value of fish roe, ...
