The implementation, functional features and advantages of the objects of the present invention will be further described with reference to the accompanying drawings.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
Since the human body cannot synthesize selenium by itself, it can only be supplemented by dietary intake. The best mode for supplementing selenium is to eat natural selenium-rich food, the current selenium-rich products in China mainly comprise selenium-rich tea, selenium-rich rice, selenium-rich eggs and selenium-rich beverages, and the processing of selenium-rich meat products is rare.
In view of the above, the invention provides the selenium-rich dried pork slice, and the selenium content of the selenium-rich dried pork slice can be stably controlled.
The invention provides an embodiment of a selenium-rich dried pork slice, which comprises the following raw materials of pork, selenium-rich vegetable powder and compound salt, wherein the selenium content of the selenium-rich dried pork slice is 20-100 mu g/100 g; the compound salt comprises sodium chloride and potassium chloride, and the mass percent of the potassium chloride in the compound salt is 35-30%.
According to the technical scheme, the selenium-rich vegetable powder with high selenium content and easily controlled selenium content is used as an auxiliary material and is used as a raw material together with pork to prepare the selenium-rich dried pork slice, compared with the conventional selenium-rich pork raw material, the selenium content is more conveniently controlled, and the selenium content stability of the product is further ensured; potassium chloride with salty taste similar to that of salt is adopted to replace part of sodium chloride, so that the use amount of sodium salt in the selenium-rich dried pork slices is effectively reduced, the selenium-rich dried pork slices are healthier to eat, meanwhile, the potassium content in the selenium-rich dried pork slices is increased, and the nutritional value of the selenium-rich dried pork slices is increased.
Selenium is an important component of glutathione peroxidase in an organism, can specifically catalyze and reduce the oxidation-reduction reaction of glutathione and peroxide in the organism, and belongs to essential nutrient elements of a human body. The human body cannot synthesize selenium by itself, and can only take in and supplement selenium actively, and the selenium is usually supplemented by eating selenium-containing animals and plants. The selenium-rich animal is fed with the selenium-rich feed or the selenium-rich plants to improve the selenium content in the meat, and the selenium-containing plants gather the selenium content by absorbing selenium elements in soil, so that the selenium content of the selenium-rich plants is higher and easier to control compared with the selenium-rich meat, and the planting cost of the selenium-rich plants is lower. The selenium-rich vegetable powder is selected instead of the selenium-rich pork as the raw material, so that the requirements on the quality and the type of the pork are reduced, and the cost of the raw material is also reduced.
The invention does not limit the variety of the selenium-rich vegetable powder, and can be vegetables rich in selenium element of any variety such as broccoli, cabbage, radish, cucumber and the like. Selenium-rich broccoli powder is preferably selected in the embodiment, and the selenium content of the selenium-rich broccoli powder is 1000-2000 mg/1000 g. According to the requirement of the selenium content of the final product, the amount of the selenium-rich vegetables added is calculated, so that the product can be accurately controlled
The potassium chloride has the salty taste characteristic similar to that of the salt, and meanwhile, the potassium is one of the essential elements of the human body, can adjust the proper osmotic pressure in cells and the acid-base balance of body fluid, participates in the metabolism of sugar and protein in the cells, and the substitution of the potassium chloride for partial sodium chloride can also provide salty taste for the selenium-enriched dried pork slices, can help the human body to supplement the potassium, effectively reduces the sodium salt content in the selenium-enriched dried pork slices, and is healthier to eat. However, the amount of potassium to be incorporated is not limited to be too large, and therefore, in the present embodiment, the mass percentage of potassium chloride in the complex salt is 35% to 30%, preferably 30%. Further, sodium chloride and potassium chloride are both food grade.
In addition, the raw materials of the selenium-rich dried pork slice provided in this embodiment further include isolated soy protein, complex phosphate, starch, carrageenan, D-sodium erythorbate, and the like, and in order to obtain a better taste and flavor, in this embodiment, the raw materials of the selenium-rich dried pork slice include: every 100 parts of pork is added with 2-3 parts of complex salt, 0.01-0.07 part of selenium-rich cerulenin, 2-4 parts of soybean protein isolate, 0.2-0.3 part of complex phosphate, 2-4 parts of starch, 0.2-0.3 part of carrageenan and 0.02-0.03 part of D-sodium erythorbate.
Further, the selenium-rich dried pork slice also comprises the following seasonings in parts by weight: every 100 parts of pork is added with 4-6 parts of white granulated sugar, 2-3 parts of soy sauce, 0.4-0.6 part of cooking wine, 0.2-0.3 part of black pepper, 0.2-0.3 part of white pepper, 0.2-0.3 part of ginger powder and 0.2-0.3 part of thirteen spices, so that the flavor of the product can be enriched.
In addition, the invention also provides a preparation method of the selenium-rich dried pork slice, the preparation method is simple to operate and short in production period, and the prepared selenium-rich dried pork slice is good in taste, unique in flavor and stable in quality. Fig. 1 is an embodiment of a preparation method of selenium-rich dried pork slices provided by the invention.
