Method for preparing novel shrimp seasoning

Abstract

The invention discloses a method for preparing a novel shrimp seasoning. The method mainly comprises the following steps of: performing pretreatment; performing advanced enzymolysis, namely, adding water into shrimp slurry, uniformly stirring the mixture, adjusting pH value, raising temperature to 42 to 56 DEG C, adding 200 to 300 U / g papain based on the weight of the slurry, hydrolyzing for 3 to5 hours, raising the temperature to 95 DEG C after enzymolysis is finished and killing enzyme for 10 to 15 minutes so as to obtain a hydrolysate; performing centrifugal filtering; performing condensation; performing a thermal reaction to obtain thermal reaction liquid; performing salting and fermentation, namely, fermenting shrimp or a processing byproduct thereof to obtain a fermentation product, and performing extraction and filtering to obtain filtrate; mixing a thermal reactant and the extracted filtrate, and performing homogenizing under a high pressure; and performing spray drying to obtain the shrimp seasoning. The preparation method provided by the invention combines a modern biotechnology measure and the conventional fermentation process to obtain the novel high-grade shrimp seasoning which has shrimp palatedfullness, mellowness, fullness, soft taste, fineness and extremely high nutritional value.

Description

technical field

[0001] The invention relates to the field of seasoning and food biotechnology, in particular to a preparation method of a novel shrimp seasoning. Background technique

[0002] Shrimp is one of the bulk aquatic products in my country, and it is also the largest export product in my country's agricultural aquaculture industry. The cultured species include Penaeus vannamei, Penaeus chinensis, Penaeus japonicus, and Penaeus monodon. In 2009, my country's shrimp output was more than 1.8 million tons, accounting for 40% of the world's total shrimp output, and the export volume was about 300,000 tons, with an export value of more than 1.5 billion US dollars. Prawns are delicious and nutritious. It is a good nutritional product with high protein and low fat. Every 100g shrimp meat contains 20.6g protein, 0.7g fat, 0.2g carbohydrate, 35mg calcium, 150mg phosphorus, 0.1mg iron, 0.01mg thiamine, Riboflavin 0.11mg, niacin 1.7mg, contains 90kcal of heat, and is rich in t...
