Animal and plant double-protein small crisp meat base material prepared by high-humidity extrusion process and processing method thereof
Technical Field
The invention discloses an animal and plant double-protein small crisp meat base material prepared by a high-humidity extrusion process and a processing method thereof, and relates to the technical field of food processing.
Background
The small crisp meat is a traditional dish in Shaanxi province, Henan province, Shanxi province and the like, and is deeply loved by people in all parts of China. The traditional crisp pork is prepared by selecting fresh pork (or chicken) as a raw material, cutting into strips, pickling, coating slurry, frying, dipping with spiced salt or cumin, and eating, and the taste is crisp, tender and smooth, and oily but not greasy.
The traditional method for processing the small crisp meat is a manual workshop method, the processing process is time-consuming and labor-consuming, and the product quality is good and uneven. At present, the research direction of related crisp meat is to optimize the processing technology and the preparation method: a novel preparation method of small crispy meat is disclosed in Chengxiang (publication No. CN 106578970), which optimizes the process of small crispy meat to make it suitable for industrialized production; wanyayun (publication No. CN 111000149 a) discloses a method of how to slow down the problem of too rapid quality deterioration of frozen stored small crisp meats during the freezing storage process.
The main materials of the traditional small crisp meat are livestock meat, and no report related to the small crisp meat with vegetable protein sources is found so far. The development of vegetarian meat products based on high moisture extrusion technology is the focus of research currently and for some time in the future. The high-humidity extrusion technology is a technology for producing textured vegetable protein by using soybean protein isolate and the like as raw materials, has high product texturing degree and less nutrient loss, and does not need rehydration. Jiangtianzhou (publication No. CN 111838401A) discloses a method for preparing artificial diced chicken by high-humidity extrusion, which takes soybean protein concentrate and wheat gluten as raw materials, and the product has the flavor similar to chicken; queen bee milk (publication No. CN 112167426A) discloses a method for preparing vegetarian beef base material by high-humidity extrusion technology, which uses isolated soy protein and wheat gluten as main protein raw materials, and the vegetable protein product obtained by extrusion has a beef-like taste.
However, the eating habit of the vegetarian meat product which is only eaten with animal meat or vegetable protein does not meet the requirement of balanced nutrition of food, the risk of obesity and cardiovascular diseases can be increased when the meat is excessively eaten, and the problems of malnutrition and the like can be caused when the vegetarian meat product is purely eaten. The animal protein/plant protein dual protein system caters to the current trend of nutritionally balanced diets to some extent. Due to the addition of the vegetable protein, the protein biological value of the product is superior to that of pure animal protein, the product completely meets the requirement of dietary guidelines, and the nutritional health of the product is superior to that of the traditional crisp meat; meanwhile, due to the addition of animal protein, the meat is obviously superior to the meat analogue in the aspects of functional gel property and the like.
The core difficulty of the development of the double-protein product lies in breaking the gap between heterologous proteins, enabling the two to be mutually cross-linked and fused, and building a new gel network system. Currently, a great deal of research shows that the addition of vegetable proteins to meat products in small amounts can improve the quality of meat products, such as: good elasticity, water retention, slicing property, improved gel structure, etc. However, the addition of vegetable proteins in large quantities to meat products brings with it many new problems, such as: the crosslinking degree of the two components is poor, the gel performance is poor, the double-protein taste is rough, the beany flavor is heavy, and the like. Therefore, the addition amount of the vegetable protein in the meat products is controlled to be 3-10 percent at present.
According to the method, after the characteristics of animal protein and plant protein are analyzed systematically, myofibrillar protein is extracted from edible livestock meat, soybean protein isolate is extracted from soybean, the myofibrillar protein and the soybean protein isolate are fused by means of a high-humidity extrusion process, and auxiliary reagents such as biological enzyme, polyphenol and polysaccharide are added to synergistically strengthen cross-linking between the myofibrillar protein and the soybean protein, so that the addition amount of the plant protein can be adjusted by more than 50%.
The invention provides a new way for the novel protein feeding with nutrition, delicacy and industrialized production.
The invention relates to a new application field of high-humidity extrusion technology. In practice, the application of new technologies to traditional technologies is constantly expanding, being the sheng mission of my generation food people.
