Embodiment 1

[0016] A preparation method of seafood essence, all the percentages and ratios involved are mass ratios, specifically as follows:

[0017] 1) Treatment of whitebait: Because of the characteristics of whitebait, it must be processed within 3 hours, fresh whitebait is taken, and then quick-frozen and brought back for use. Carry out microwave radiation heat treatment to it, microwave power 800W, time 5 minutes, then cool down again. Add 20% water and stir well, microwave power is 400w, time is 10 minutes. Obtain whitebait treatment mixture.

[0018] 2) Enzymolysis of whitebait treatment mixture with immobilized compound enzyme: Enzymolysis of whitebait treatment mixture under microwave and ultrasonic conditions: flavor protease + compound flavor protease (1:1) enzymolysis conditions are: The concentration of whitebait treatment mixture is 8%, the initial pH of enzymolysis is 7, the amount of enzyme added is 1.5%, the microwave power is 450w, the ultrasonic power is 550W, the en...

Embodiment 2

[0022] Another preparation method of seafood essence is as follows:

[0023] (1) The processing of whitebait: fresh whitebait is brought back to use through speed, it is carried out microwave radiation heat treatment, microwave power 800W, time 5 minutes, then cools down again. Add 15% water and stir evenly, microwave power is 400w, and the time is 5 minutes. Obtain whitebait treatment mixture.

[0024] (2) Enzymolysis of whitebait treatment mixture with immobilized compound enzyme: under microwave and ultrasonic conditions, enzymolysis of whitebait treatment mixture: flavor protease + compound flavor protease (1:1) enzymolysis conditions are : Whitebait treatment mixture concentration 15%, initial enzymolysis pH 7, enzyme addition 3.2%, microwave power 500w, ultrasonic power 500W, enzymolysis temperature 75°C, enzymolysis time 25 minutes. After enzymatic hydrolysis, filter and centrifuge. An enzymatic hydrolyzate of whitebait is obtained.

[0025] (3) Carry out Maillard r...

Abstract

The invention discloses a preparation method of a seafood flavor. The preparation method includes subjecting quickly-frozen whitebait to microwave radiation thermal treatment, cooling the whitebait, and mashing the whitebait; allowing enzymolysis with a compound flavourzyme and a flavourzyme, after enzymolysis, performing filtering and centrifuging to obtain an enzymatic hydrolysate subjected to Maillard reaction to obtain a flavor enhancer, and adding the flavor enhancer to a flavor. By subjecting the whitebait to microwave/ultrasonic and immobilized enzyme combination, the flavor and fresh of the whitebait can be well reserved; ultrasonic enables efficient reaction, with low cost and no pollution, and operating is convenient; the seafood flavor has unique flavor and fresh and has a promising market prospect in flavor application.

Description

technical field [0001] The invention belongs to the field of food additives, in particular to a preparation method of seafood essence. Background technique [0002] Whitebait is known as a delicacy in China. Whitebait is a very calcium-rich, high-protein, low-fat fish. The protein content in whitebait is 72.1%, and the amino acid content is also quite rich. The nutritional value is extremely high. Lung and other functions, it is a top-notch nourishing tonic, and its function of health and longevity has been confirmed by the international nutritional circles. [0003] However, whitebait is easy to die after being caught, so it should be processed within three hours, otherwise it will affect nutrition. This poses a problem in its handling. And how to substitute its deliciousness and flavor into the essence is the object of research now. Contents of the invention [0004] In order to overcome the problems in the prior art, the purpose of the present invention is to provid...
