Embodiment 1

[0016] (1) Grass carp muscle pretreatment: Fresh grass carp is peeled, boned and visceral, the resulting fish muscle is crushed with a blender, and 4 times the volume (W / V) of 0.02mol / L pH7.5 phosphate buffer solution is added to the minced fish , stir the homogenate with a mixer for 60s, centrifuge the muscle homogenate at 4°C, 2000×g for 15min, remove the water-soluble protein, and obtain a precipitate, wash three times with the above-mentioned phosphate buffer solution (4 times the volume) under the same stirring and centrifuging conditions Above, the obtained precipitate was washed three times with 4 times the volume of 0.1mol / L NaCl solution under the same conditions as above, and after the last stirring and homogenization, it was filtered with gauze to remove the connective tissue in the muscle homogenate. Obtain grass carp muscle homogenate (the main component is salt-soluble protein);

[0017] (2) Ultrasonic treatment: Dilute the homogenate obtained in step (1) to 40mg...

Abstract

A method for improving gel properties of Ctenopharyngodon idellus surimi and improving mouthfeel thereof, comprising: using ctenopharyngodon idellus as a raw material to perform pretreatment, meat extraction, low-concentration saline solution based rinsing, ultrasonic treatment, cutting and stirring, two-stage heating, packaging and frozen storage. According to the method, the prepared surimi is good in gel properties, fine and smooth in mouthfeel, better in quality and longer in shelf-life. Rinsing is performed by using a low-concentration saline solution, so that the obtained surimi is high in saline soluble protein content, and high in purity. The ultrasonic technique enables the surimi to be more uniform, fine and smooth in texture, improves the gel strength and whiteness of the surimi, and the sterilization effect of the ultrasonic technique improves the quality of surimi products and prolongs the shelf-life of the surimi products. The two-stage heating method allows the surimi to pass a 50-70 DEG C gel deterioration temperature region quickly, so as to avoid surimi gel deterioration. The method is simple and convenient to operate, is low in cost, high in efficiency, and suitable for industrialized production, provides a novel idea for high-quality fresh water surimi production, and provides a novel method for fresh water surimi modification and industrialized production.

Description

technical field [0001] The invention relates to a method for enhancing the gel properties of grass carp surimi and improving its mouthfeel by ultrasonic treatment. Background technique [0002] Grass carp is one of the famous "Four Major Fishes". Its meat is tender, delicious, nutritious and high in protein content, up to 26%. It is a high-quality raw material for the production of freshwater surimi with high economic value. The surimi-like product made from raw fish after meat picking, rinsing, fine filtration, dehydration, stirring and freezing is called surimi, which has excellent properties such as gelatinity, water holding capacity, emulsification, etc. The ingredients are widely used in the food industry. Grass carp muscle protein mainly contains salt-soluble protein, water-soluble protein and insoluble protein protein. Myofibrillar protein is the functional component of surimi products and the main factor to maintain the texture and water holding capacity of surimi...
