Embodiment 1

[0028] 1. First, thaw the frozen cod fish fillets, wash them, and use a grinder to crush and homogenize them into surimi;

[0029] 2. Weigh 1500g of surimi, add deionized water of equal mass, cook at 121°C for 30min, then cool to room temperature;

[0030] 3. Adjust the pH value to 7.5, add protease A and protease P according to the quality of surimi: enzyme = 8000: 1 (W / W), react at 45°C and 100rpm for 6h;

[0031] 4. After the reaction, adjust the pH value to 7.5, add protease C and protease G according to the mass of surimi: enzyme = 8000: 1 (W / W), and react at 60°C and 100rpm for 6h;

[0032] 5. After the reaction is over, treat it in a boiling water bath for 10 minutes to terminate the reaction;

Abstract

The invention discloses a delicious food flavor derived from fish bone protein and a preparation method thereof. The product obtained by the present invention has a mellow, full-bodied seafood flavor and a long-lasting fragrance, and is a new type of umami food essence; at the same time, it can be used as a freshening agent for beef, pork, and chicken flavor essences to improve the mouthfeel and aftertaste of the product, improve the The competitiveness of the product can be applied to instant noodles, condiments and seafood-flavored puffed food ingredients, etc., and has broad market prospects. The process of the invention is simple and feasible, and is easy for industrialized production.

Description

technical field [0001] The invention relates to the field of food additives, in particular to an umami food flavor derived from fish bone protein and a preparation method thereof. Background technique [0002] Salty flavors are an important component of food flavors and are widely used in instant noodles, meat products, chicken essence and compound seasonings. Its main production methods are chemical synthesis and Maillard reaction. At present, most of the salty flavors produced at home and abroad use meat or processing by-products (chicken, pork, beef) as the main raw materials. However, due to the influence of factors such as meat source, freshness, and logistics distribution, the different degrees of endogenous enzyme action lead to different degrees of protein degradation, resulting in large differences in the composition and content of amino acids and peptides in protein hydrolyzates. Differentiation leads to unstable flavor and quality of the final Maillard reaction p...
