Description

Pickling liquid, preparation method and application thereof
Technical Field
The invention relates to the field of food, and relates to a pickling liquid, a preparation method and application thereof.
Background
A large amount of salt (sodium chloride) can be added in the process of pickling traditional salted and cured meat products, so that the salt forms extremely high osmotic pressure on the surfaces of the salted and cured meat products, and the method is very key to pickling of the meat products: on one hand, the osmotic pressure difference between the surface and the inside of the cured meat product can promote sodium chloride to permeate into the meat product to react with protein and fat, so that the adhesiveness of the meat is enhanced, the texture is improved, and the meat product forms unique flavor; on the other hand, the high osmotic pressure difference can cause the rupture of microbial cell membranes on the surface of the meat product, thereby inhibiting the growth of harmful microorganisms and prolonging the shelf life of food.
However, it has been shown that sodium ions in common salt (sodium chloride) are closely related to cardiovascular diseases such as hypertension, and that excessive intake of sodium ions increases the risk of the disease. However, a large amount of salt is often added in the process of pickling cured meat products, which is contrary to the low-salt and health concept advocated at present. Based on this, technologists make a series of attempts to reduce the use amount of salt, and an effective method is to replace or partially replace sodium chloride with other salt substances to achieve the purpose of reducing the content of sodium ions. The salts commonly used at present are: potassium chloride, magnesium chloride, calcium chloride, potassium lactate, calcium glutamate, and the like, wherein potassium chloride is considered to be the most effective substitute because the molecular weight is not much different from that of sodium chloride, which is favorable for the permeation of molecules, and the intake amount of potassium chloride has no loss of functionality to the human body.
However, the amount of potassium chloride used instead of sodium chloride should not be too large. It was found that a substitution amount exceeding 30% of sodium chloride resulted in a bitter taste, and that a bitter taste exceeding 40% was clearly unacceptable. In the case where the amount of potassium chloride added cannot exceed 30%, its substitution effect for sodium chloride is limited, and in this case, the amount of total salt can only be reduced in order to reduce the content of sodium ions. However, after the amount of salt is reduced, the osmotic pressure difference formed on the surface of the meat product is reduced, so that in the process of pickling the meat product, on one hand, the inward permeation speed of salt ions is reduced, the flavor substances are slowly formed, and on the other hand, the osmotic pressure difference is not strong enough to kill microorganisms on the surface of the meat product, so that the meat product is easy to deteriorate.

Comparative example 1
The pressed salted duck was prepared in the same manner as in example 3 except that the solvent in the pickling solution was clear water.
Comparative example 2
Pressed salted duck was prepared in the same manner as in example 3 except that the solute contained in the pickling solution did not contain calcium ascorbate.

Test example 1 Permeability measurement
The stronger the permeability is, the more salt ions enter the pressed salted duck, so the strength of the permeability of the pickling liquid can be analyzed by measuring the content of the salt ions in the pressed salted duck.
The determination method comprises the following steps: the breast meat of the salted pressed salted duck is removed, water is added for crushing, and the content of chloride ions in the pressed salted duck prepared in example 3 and comparative example 2 is measured according to GB 5009.42-2016 standard salt index for food safety.
The results are shown in Table 1.
Table 1 results of salt content test
Figure RE-725499DEST_PATH_IMAGE001
And (4) analyzing results: from the experimental results, it can be seen that, compared with comparative example 3, example 3 shows that ascorbic acid can significantly increase the amount of salt ions permeating into the meat product, and thus plays a role in increasing permeability.
Test example 2 texture evaluation
In the preparation of the pressed salted duck, the curing method influences the texture of the pressed salted duck, so the application evaluates the influence of different curing methods on the pressed salted duck by performing texture tests on the pressed salted duck in determination example 3 and comparative examples 3 and 4.
The determination method comprises the following steps: measuring the texture of the pressed salted duck by using a texture analyzer, pretreating duck breast meat, placing on an object stage, aligning a P/0.5 probe to the center of a sample, and measuring the bean curd TPA. The measurement parameters are: pre-measurement speed 1mm/sec, mid-measurement speed 1mm/sec, post-measurement speed 1mm/sec, strain 30%, time 5s, trigger type: auto, trigger force: 5g, samples were tested for hardness, elasticity and chewiness, with triplicates per sample.
And (3) testing results: the test results are shown in table 2.
TABLE 2 texture measurement results
Figure RE-651867DEST_PATH_IMAGE002
And (4) analyzing results: according to experimental results, in the process of applying the pickling liquid to the preparation of the pickled and preserved meat products, the hardness of the pressed salted ducks pickled by different methods is not greatly different, but the three-stage pickling is obviously better than the other two methods in terms of elasticity and chewiness, so that the three-stage pickling of the pressed salted ducks can promote salt ions to uniformly enter meat products and bring better texture.
Test example 3 sensory evaluation
The sensory evaluation can be used for evaluating the smell, taste, color and the like of the pressed salted duck, so that the influence of adding liquiritigenin, directly using clear water as a solvent to prepare a pickling solution and three-stage pickling on the pressed salted duck is compared.
Evaluation criteria: the sensory evaluation criteria are designed according to the criteria on sensory requirements in GB 2730-2015 national food safety standard pickled preserved meat product, and are shown in Table 3.
TABLE 3 sensory evaluation criteria
Figure RE-184349DEST_PATH_IMAGE003
The experimental results are as follows: the results are shown in Table 4.
TABLE 4 sensory Scoring results
Figure RE-537969DEST_PATH_IMAGE004
And (4) analyzing results: the experimental results show that in comparison with example 4, in terms of taste, although the scores of example 3 are in the scoring range of 'uniform taste, moderate saltiness and no peculiar smell', the overall score of example 4 is higher than that of example 3, which indicates that the overall flavor of the pressed salted duck added with glycyrrhizin is slightly higher than that of the pressed salted duck without glycyrrhizin; in example 3 and comparative example 1, the overall taste is low in color, state and taste mainly because the clear water is lack of nutrients capable of enriching microorganisms and cannot be blended with the taste characteristics of the product at the beginning, and in example 3 and comparative example 2, the main difference is the taste score mainly because the salt ion permeability is reduced after calcium ascorbate is not added; example 3 compared with comparative example 3.4, the main difference is the scores of the state and the taste, which shows that the whole state and the taste of the skin of the pressed salted duck which is not cured in three stages are lower than those of the pressed salted duck which adopts the process.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, those skilled in the art will appreciate that; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
