Description

Processing method of low-sodium prepared sliced meat
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a processing method of low-sodium prepared sliced meat.
Background
With the improvement of living standard, the consumption of meat products by the nation is increased year by year. The conditioning meat product is a non-instant meat product which is made by taking livestock and poultry meat as a raw material, adding seasonings and other auxiliary materials after primary processing such as cutting or trimming, processing by related processes, and storing, transporting and selling under the condition of freezing or refrigerating. The conditioning meat product is an important component of modern meat product processing, has the characteristics of convenience, small volume, nutrition and various flavors, conforms to the current diet trend, and is favored by public institutions and families of all countries in the world. Therefore, the market demand of the current conditioning meat products is vigorous, and the development potential is huge.
Sodium is an essential nutrient for human body, and a certain amount of sodium is required to be taken every day to maintain normal physiological functions. However, excessive intake of sodium salt can increase the blood pressure of human body, increase the incidence of cardiovascular diseases, and cause a series of diseases such as gastric cancer and osteoporosis, and moderate reduction of sodium intake can effectively reduce the incidence of cardiovascular diseases. Sodium chloride is an essential additive in meat product processing, can improve the taste and texture of meat products, can inhibit the growth of microorganisms, prolongs the shelf life and has important influence on the quality of meat products. The problem of excessive use of sodium salts is common in the meat product processing industry. At present, the average sodium content in livestock meat products is 1.2%, and according to the requirements of salt reduction guidelines of Chinese food industry, the salt reduction target of reducing the sodium content by 20% needs to be achieved in 2030. However, if the amount of sodium chloride used is directly and greatly reduced in the processing process of the meat product, certain adverse effects can be caused on the quality of the meat product, such as reduction of water retention, deterioration of flavor, reduction of palatability and the like. In past practice, the use of 20% -30% of sodium salt can be reduced by a direct salt reduction method on the premise of not influencing the taste perception of consumers, but the method needs the participation of the whole industry, takes years and is high in energy consumption. Therefore, on the basis of reducing the sodium content of the prepared meat product, the development of the low-sodium prepared meat product with good texture, tenderness and flavor is urgently needed by the food industry and is a necessary trend for the meat industry to follow the development of healthy life in the future.
Disclosure of Invention
The invention aims to develop a processing method of low-sodium conditioning meat slices, which reduces the sodium content in the conditioning meat by adjusting a formula of compound substitute salt and combining means such as saline injection and the like, overcomes the quality defect caused by salt reduction, and produces the low-sodium conditioning meat slices with excellent texture, excellent tenderness and good flavor.
In order to achieve the purpose, the invention adopts the following technical scheme:

Further, the low-sodium salt water injection in the step (2) is to inject the sliced meat in a full-automatic saline injection machine, and the injection rate is 15-20%; the low-sodium salt water is prepared by completely dissolving 2-3 parts by weight of low-sodium compound salt, 0.1-0.2 part by weight of D-sodium erythorbate, 0.1-0.2 part by weight of compound phosphate, 0.5-0.6 part by weight of white granulated sugar, 0.2-0.3 part by weight of oyster sauce, 0.7-0.8 part by weight of ginger powder, 0.5-0.6 part by weight of garlic powder and 0.2-0.3 part by weight of monosodium glutamate in 40-45 parts by weight of water, and refrigerating at 4 ℃ for later use.
Wherein, the low-sodium compound salt is prepared by mixing 1.2 to 1.8 parts of sodium chloride, 0.4 to 0.6 part of potassium lactate, 0.2 to 0.3 part of calcium ascorbate and 0.2 to 0.3 part of magnesium chloride according to parts by weight; the composite phosphate is prepared by mixing sodium tripolyphosphate, sodium pyrophosphate and sodium hexametaphosphate according to the weight ratio of 2:2: 1.
The potassium lactate has a certain antibacterial effect, and can improve the water binding capacity of the product and improve the taste and flavor. The calcium ascorbate is used as an antioxidant and a preservative for processing the meat products, has a remarkable influence on the redox capability of the meat products, and is also beneficial to the formation of stable color for curing the meat products. The magnesium chloride can promote myofibril dissolution, improve protein emulsification effect, and reduce juice loss.
Further, the vacuum tumbling is adopted in the step (2) for pickling, specifically, intermittent pickling is carried out in a manner of tumbling for 20min and stopping pickling for 10min, and the total treatment time is 4-5 h; wherein the parameter conditions during rolling and kneading are as follows: the vacuum degree is 0.08-0.09MPa, the rotating speed is 4-6r/min, and the temperature is 0-4 ℃.
During the processing of the conditioning meat product, the connective tissue between myofibroblasts and muscles can be cut and broken through rejuvenation treatment of the blade, myofibrillar protein is released, the normal tissue structure of the meat is destroyed, the surface area of the meat is increased, and the adhesiveness and the water holding capacity of the meat are improved by combining injection and rolling mechanical treatment, thereby achieving the purpose of improving the quality of the meat product.
Further, the packaging and storing in the step (3) are vacuum packaging in an environment of 10-15 ℃, and quick-freezing and storing within 30 min.
The low-sodium conditioning sliced meat prepared by the method has the advantages of regular appearance, bright color, soft texture after the product is cooked, moderate salty taste, and similar mouthfeel and flavor to the conditioning meat product without salt reduction.
The invention has the beneficial effects that:
(1) the low-sodium composite salt uses potassium lactate, calcium ascorbate and magnesium chloride to partially replace salt, can improve the content of calcium and magnesium elements while reducing the sodium content of the conditioned meat product, makes up the defect of low content of calcium and magnesium in the meat product, and is favorable for meeting the requirement of the daily calcium and magnesium intake of a human body.
(2) According to the invention, low-sodium compound salt, compound phosphate, D-sodium erythorbate, white granulated sugar and the like are prepared into low-sodium saline water according to a certain proportion, and injection pickling is carried out by a modern injection technology, so that the uniform distribution of a pickling liquid in meat can be promoted, the pickling efficiency is improved, the dissolution of myofibrillar protein in muscle is promoted, the texture, color, flavor and the like of the conditioned meat slices are improved, and more consumers can enjoy the meat slices.

Table 1 shows a comparison of the quality index of the prepared slices prepared by different methods. As can be seen from table 1, in the comparative example, by adjusting the formulation of the complex salt in the pickling solution, i.e., replacing part of sodium chloride with potassium lactate, calcium ascorbate and magnesium chloride, the sodium content in the conditioned meat pieces was significantly reduced (from 201mg/100g to 155mg/100g, by 22.9%) in comparison with comparative example 1, and under the action of the complex salt, the solubility of myofibrillar proteins was increased, the shear force value was reduced, and the color was improved, but there was a sensory defect, and the overall acceptability score was slightly lower. In example 1, compared with comparative example 2, the sodium salt amount of the prepared sliced meat can be reduced by using low-sodium saline for injection treatment, the damage degree of the muscle tissue structure in the beef is further increased, the solubility of myofibrillar protein is improved, the tenderness and the texture of myofibrillar protein are greatly improved, the overall acceptability of the myofibrillar protein in sense is close to that of comparative example 1, namely the mouthfeel of the common prepared sliced meat is achieved, and the quality defect problem caused by salt reduction is solved. Therefore, the low-sodium salt water is combined with the injection treatment, so that the low-sodium salt water can be uniformly distributed in the meat slices, the pickling effect is improved, and the quality of the low-sodium conditioning meat slices is improved.
FIG. 1 is a radar comparison graph of sensor response values of conditioned meat slices prepared by different methods. As can be seen from the figure, the radar chart of the conditioned beef sample obtained in example 1 is similar to that of the conditioned beef sample obtained in the comparative example, but the response values of the conditioned beef sample of example 1 in sensors R2 (nitrogen oxide), R6 (short-chain alkane), R7 (sulfide) and R9 (aroma and organic sulfide) are higher than those of the comparative example, which shows that the low-sodium saline water combined with the injection treatment can promote the generation of flavor substances in the conditioned meat slices and enrich the flavor of the low-sodium conditioned meat slices.
