Problems solved by technology

However, due to the high water content of surimi, the water loss is serious during the extrusion cooking process, and the raw materials often spray at the discharge port or reflux at the feed port, so it is usually necessary to gel first and then extrude. The gel properties of surimi remolded products deteriorate seriously and the taste decreases due to the process
This problem is a big problem in the extrusion processing of this fish meat product

Abstract

The invention relates to instant dietary fiber fish strips and a preparation method thereof. Minced fish meat is taken from fish pieces, rinsed with water, placed in a vacuum chopping mixer to be chopped, and then mixed with a psyllium seed gum and table salt to obtain a paste; the paste is added to a twin-screw extruder, formed through a mold at the exit, and divided into a predetermined size through a cuter to obtain the instant dietary fiber fish strips. According to the instant dietary fiber fish strips and the preparation method thereof, the water activity of the chopped fish meat is reduced by adding a certain amount of the psyllium seed gum to the raw materials of the chopped fish meat, and the evaporation of water in the chopped fish meat during the extrusion process is suppressed,and the problem of spraying in the extrusion process is solved. In addition, a certain improvement of the nutritional quality of the fish strips is achieved, and the fish strips have the health carefunctions of moisturizing the intestines, relaxing the bowels, lowering blood sugar and regulating blood lipids and the like.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to instant dietary fiber fish sticks and a preparation method thereof. Background technique [0002] my country is a large fishery country, and has been focusing on the development of frozen products for many years, while ignoring the development of new technologies, new processes and new products for deep processing of low-value fish to a certain extent. Extrusion, puffing and cooking technology is a high-tech in food processing in the world today. Applying this technology to develop textured fish products, making low-value natural fish protein raw materials has good chewiness and storage resistance, convenience, nutrition, hygiene, and flavor. It is a new type of ready-to-eat fish meat strips. The food is crispy and elastic, convenient to eat, easy to digest, and has high added value and nutritional characteristics such as high protein content, low fat, and no ...
