Description

Method for preparing functional seafood seasoning base stock
Technical Field
The invention belongs to the field of deep processing of aquatic products, and particularly relates to a method for preparing a functional seafood seasoning base stock.
Background
The annual yield of seasonings in China is about 1500 million tons, the annual sales amount is about 4000 hundred million RMB, the industry scale is huge, but the market competition is fierce, products with high advantages in the industry are rare, the product differentiation is small, the homogenization phenomenon is obvious, and the competitiveness is lacked.
Under normal physiological environment, the organism can generate a small amount of Reactive Oxygen Species (ROS), and an antioxidant system (including antioxidant enzyme and non-enzyme antioxidant) in the organism can rapidly eliminate excessive free radicals so as to maintain the physiologically proper concentration of the free radicals. However, when the body is damaged by oxidation, the body may suffer from oxidative stress due to excessive accumulation of free radicals. The occurrence of many chronic diseases in human body such as rheumatism, atherosclerosis and the like has a great relationship with the oxidative damage of free radicals of the body. Therefore, the proper intake of the antioxidant by the human body is beneficial to maintaining the balance of free radicals in the body, can effectively prevent the oxidative stress of the body and promote the health of the body.
The oyster (Ostrea gigas tnunb) is rich in nutrition, is rich in high-quality protein and various amino acids necessary for human bodies, is called 'milk in the sea', and is also a processing raw material of the traditional seasoning oyster sauce in China. The oyster resources are rich in China, but the processed product is mainly dried oyster, and the cooking liquor in the processing process of the dried oyster is processed into oyster sauce, so that a high-quality deep-processed product is lacked. Therefore, the invention mainly utilizes the high-quality protein in the oysters to prepare the functional seafood seasoning base stock with good flavor and antioxidant activity, develops high-quality seasoning products and is beneficial to promoting the development and utilization of oyster resources.
Disclosure of Invention
The invention aims to provide a method for preparing a functional seafood seasoning base stock, which has good flavor, small fishy smell and easy digestion and absorption by human bodies.
The invention is realized by the following technical scheme;
the invention relates to a method for preparing a functional seafood seasoning base stock, which comprises the following steps:
(1) ultrasonic treatment and freezing of raw materials: taking fresh oyster meat as a raw material, rinsing with saline water to remove impurities, carrying out ultrasonic treatment for 10-60min, and freezing the oyster meat at the temperature of-3 ℃ to-80 ℃;
(2) frying: frying the frozen oyster meat in edible oil for 1-10 min, and performing deodorization treatment to prepare fried oyster meat;
(3) enzymolysis: adding purified water with the mass 2-5 times that of the raw materials into the fried oyster meat, shearing and grinding the mixture into pulp, preparing fried oyster meat pulp, adjusting the pH to 6.0-8.0, adding compound protease into the fried oyster meat pulp according to 100-500U/g of the raw materials, and performing heat preservation and enzymolysis for 1-6 hours at the temperature of 45-55 ℃ to prepare enzymolysis liquid;
(4) maillard reaction: and adding maltose syrup and L-methionine into the enzymolysis liquid, and reacting for 60-180 min at 95-100 ℃ to prepare the functional seafood seasoning base stock with good flavor.
In the step (1), the saline water is 2-4% (w/v) of sodium chloride aqueous solution.
In the step (1), the ultrasonic frequency range is 20 kHz-100 kHz.
In the step (2), the frying temperature is 100-125 ℃.
In the step (3), the compound protease is composed of neutral protease, papain and trypsin; the enzyme activity ratio is as follows: neutral protease: papain: trypsin is (1-2), (2-4) and (2-4).
In the step (4), the addition amount of the malt syrup is 15-20% of the raw material amount.
Further:
in the step (4), the amount of the L-methionine added is 1.0-6.0% of the amount of the raw material.
After the scheme is adopted, the invention has the following advantages:
1. the fishy smell is one of the key factors restricting the development of the marine products, and the components of the fishy smell in the fresh marine products mainly comprise volatile micromolecular aldehyde and ketone compounds. The oyster fishy smell removing method has the advantages that raw materials are deodorized by jointly applying ultrasonic treatment, freezing and frying processes, oyster cells, subcellular organelles and other tissue structures are moderately damaged by ultrasonic treatment and freezing treatment, ice crystal water molecules are rapidly vaporized under the condition of frying at the low temperature of 100-125 ℃, volatilization of fishy smell components in the oyster is accelerated, and the content of the fishy smell components is greatly reduced.
2. The oyster protein is subjected to combined enzymolysis by using neutral protease from microorganisms, papain from plants and trypsin from animals, the obtained proteolytic peptide is mainly small-molecular antioxidant peptide which is easy to digest and absorb by human bodies and has the molecular weight of less than 1000Da, and the content of free amino acids, particularly flavor amino acids, is increased.
3. The invention utilizes malt syrup with relatively weak reducibility to carry out Maillard reaction with oyster protein hydrolysate, and adds L-methionine, so that the reaction is relatively mild, the generation of dark brown melanoidin substances harmful to human bodies in the later stage of the Maillard reaction is reduced while flavor components such as furan, pyrazine compounds and the like are generated, and the soluble solid solution in the product is light yellow to amber when the reaction is finished. These maillard products both further enhance the antioxidant activity of the product and contribute to improving the flavor of the product.

And (5) analyzing the fishy smell removing effect of the oysters.
FIG. 1 is a GC-MS spectrum of the volatile components of fresh oyster meat/fried oyster meat of example 1.
Table 1 is a table of volatile components of fresh oyster meat in example 1.
Table 2 shows the volatile components of the fried oyster meat in example 1.
As can be seen from fig. 1, table 1 and table 2, the fresh oyster meat is treated by ultrasonic wave, freezing and frying, the types and contents of volatile components are significantly reduced, and particularly, typical fishy smell components, namely 1-octen-3-ol, (E) -2-octen-1-ol, (Z, Z) -3, 6-nonadienal, nonanal, (E, Z) -2, 6-nonadienal, (E, Z) -3, 6-nonadien-1-ol and (E) -2-nonenal, are significantly changed, and only 1-octen-3-ol and nonanal are detected in the fried sample, and the concentration is significantly reduced, and the fishy smell removal effect is significant.
And (5) analyzing the hydrolysis effect of the oyster protein.
Table 3 is a table of the degree of hydrolysis, DPPH clearance and hydrolyzed peptide molecular weight distribution of oyster hydrolysate.
Table 4 shows the free amino acid content in the feed solution before and after the enzymatic hydrolysis in example 1.
As can be seen from Table 3, the oyster protein hydrolysis capacity of the neutral protease is significantly stronger than that of papain and trypsin, but the DPPH and free radical removal activity of the hydrolysate is significantly weaker than that of the papain and trypsin, and the hydrolysate enzymatic hydrolysis with the three enzymes can achieve a better hydrolysis effect and obtain a hydrolysate enzymatic hydrolysate with stronger antioxidant activity. As can be seen from Table 4, the content of free amino acids in the material can be significantly increased by enzymolysis, and the total amount of flavor amino acids, i.e., umami amino acid and sweet amino acid, reaches more than 3000 mug/ml.
And (5) analyzing the aroma enhancement effect of the Maillard reaction.
FIG. 2 is a GC-MS spectrum of the volatile components of the product of example 1.
Table 5 is a table of volatile ingredients for the product of example 1.
As is clear from fig. 2 and table 5, the product of example 1 contains a large amount of flavor compounds such as furan and pyrazine, and no fishy components such as 1-octen-3-ol and nonanal were detected, and the maillard reaction flavor-enhancing effect was significant.
