Research on the application of various plant proteins in plant-based meat



Plant-based meat is based on vegetable protein, and a biomimetic meat product with animal meat fiber structure, texture, color, flavor, taste and appearance is prepared by certain technical means. The composition, type of ingredients and moisture content of the plant-based meat matrix can have a significant impact on the texture and mouthfeel of the final product.

The effects of material properties and composition on the texturing properties of extruded products are significant and complex. The formulation of commercially available textured protein-based vegetable meat mainly includes 6 ingredients (Table 1): water, protein, flavoring agent, fat, binding agent and coloring agent. Among them, water accounts for 50% to 80% of the total composition, which has the effect of plasticizing and providing juiciness in the processing of vegetable meat products. Since food colloids such as proteins and polysaccharides play a crucial role in product identification and differentiation, and fatty substances are key factors in improving flavor, texture, mouthfeel, and nutrition, this article focuses on the role of protein in plant-based meats progress in applied research.

Plant proteins are mainly composed of globular proteins, and the forces that maintain their higher-order spatial structures are mainly weak interactions such as non-covalent bonds or secondary bonds. Almost all plant proteins can be used as raw materials for the preparation of plant-based artificial meat, such as soy protein, cereal protein and potato protein are the bulk raw materials for the production of plant meat.

1. Soy Protein

Based on a comprehensive analysis of raw material yield, price, and functional properties, soy protein isolate (ISP), soy protein concentrate (SPC) and pea protein isolate (PPI) have better emulsifying, gelling, and water-holding properties due to their lower prices. and fat-binding properties, so it is commonly used in commercial plant-based meat products. Although high protein purity has no positive correlation with the texture and appearance of vegetable meat, ISP is most commonly used for high-moisture extruded vegetable protein meat due to its protein content of more than 90%, weak beany flavor and lighter color. Research. ISP can form a fibrous structure visible to the naked eye when the water content is 50% and the extrusion cooking temperature is 124, and the X-ray scanning results confirm the formation of anisotropic structure.

Pea protein is the main component in the by-product of the processing of pea starch into pea vermicelli. Pea protein is a major plant source of branched-chain amino acids (BCAAs) with a content of up to 18.1%. Branched-chain amino acids constitute about one-third of skeletal muscle protein. Supplementing branched-chain amino acids can inhibit the degradation of skeletal muscle protein, relieve delayed muscle soreness after strenuous exercise, and promote muscle recovery. Pea protein has low allergenicity, high nutritional value, strong emulsification and foam stability, and has become the mainstream vegetable meat protein raw material. However, the pea protein has a weaker gelling ability, and the prepared vegetable meat has a softer taste and poorer elasticity. In order to improve the gel properties of pea protein, different kinds of salts (NaSCN, NazSO4, CHCOONa, NaCl) are often added to the system to improve the gel strength by promoting the formation of more hydrogen bonds between pea protein molecules.
