Embodiment 1

[0031] The raw materials and formula of a kind of fish ball added with compound antifreeze agent are as follows: fish meat: 1kg, potato starch: 50g, salt: 20g, monosodium glutamate: 4g, ginger juice: 4g, pepper powder: 2g, antifreeze polypeptide: 50g , manganese sulfate monohydrate 2mg, anhydrous calcium chloride 4g, sodium lactate 2g, polydextrose 50g, maltodextrin 65g.

[0032] The production steps are as follows:

[0033] (1) Preparation of antifreeze polypeptide: take food-source pigskin collagen as raw material, soak collagen and distilled water for 3 hours at a ratio of 1:100 to make the collagen fully absorb water, add enzyme and substrate at a ratio of 1:50 Alkaline protease, adjust the pH of the enzymatic hydrolysis environment to pH9.0, heat and hydrolyze the collagen in a water bath shaker at 37°C, and the enzymatic hydrolysis time is 3h. After enzymatic hydrolysis, put it in a boiling water bath for 10 minutes to completely inactivate the protease. After cooling t...

Abstract

The present invention discloses an antifreeze polypeptid composite antifreeze agent and application, belonging to the food processing field. The antifreeze agent comprises the following components in parts by weight: 2-8 parts of antifreeze polypeptid, 1.3x10e4-5.2x10e4 parts of manganese sulfate monohydrate, 0.1-0.4 parts of anhydrous calcium chloride, 0.05-0.2 parts of an sodium lactate, 2.5-15 parts of polydextrose and 6-8 parts of maltodextrins. According to the present invention, an antifreeze polypeptide acts as a main protective agent, and is combined with inorganic salts and dietary fibers to obtain an efficient low temperature protection formula for the surimi products. The product stability of surimi products can be favorably maintained during low-temperature storage of the surimi products, and the gel strength and water retention capability of the surimi products are improved, providing protection during low-temperature refrigeration and transportation of the surimi products. The antifreeze peptides manufacturing process is mature and simple, low in production cost, and suitable for industrial production. In addition, dietary fibers and inorganic salts can improve the environment inside the human body, prevent constipation and reduce fat accumulation.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to the application of an antifreeze polypeptide compound antifreeze agent in low-temperature refrigeration of surimi products. Background technique [0002] With the development of domestic fishery and the enrichment and quality of aquatic products, solving the uneven supply of aquatic products in low and peak seasons, balancing the time to market of aquatic products, and increasing the added value of aquatic products are the core issues in the field of food processing. Fish meat is delicious and tender. It is an important source of nutrients such as protein, amino acid, fat, vitamins and minerals needed by human beings, and is an important part of people's diet. Wash low-value fish such as silver carp and carp, remove bones, skin, scales and viscera by hand, and make surimi, and then add cryoprotectant and other raw materials to make a variety of simulated foods, such as ...
