Effect of enzyme preparations on food flavor

Food flavor is the embodiment of the distinctive characteristics of one food that distinguishes it from another, mainly in terms of taste, aroma, mouthfeel, texture, etc. The taste and aroma of food are determined by the compounds in the food. For example, sweet substances are usually some sugar compounds, such as glucose and fructose; sour substances are usually some organic acids, such as citric acid and malic acid; aroma substances are composed of a variety of volatile compounds, such as alcohols, aldehydes, ketones and esters. It is because of the unique flavor of food that we can distinguish different foods and enjoy the different feelings brought by various delicacies.
There are three major conditions for the formation of food flavor:
1. Precursor substances that form flavor substances, such as amino acids and protein content, sugars, phenols, fats and other compounds. Different types of precursor substances will react differently during the cooking process to generate different flavor substances.
2. Enzymes play a very important role in the formation of food flavor. By adding appropriate enzymes during food processing, the bound flavor precursors can be hydrolyzed and flavor substances can be released through understanding and control of enzymes, so as to achieve the purpose of enhancing and improving food flavor and improving food flavor and quality.
3. Cooking methods and the use of spices and seasonings: Different cooking methods can bring different tastes and smells. Secondly, different spices and seasonings can bring different tastes and smells to food. Mastering the use of appropriate spices and seasonings can make food more colorful.
The role of enzyme preparations in food flavor
1. In the production process of fish sauce, fermented bean curd, soy sauce, and vinegar, due to the high proportion of protein raw materials and insufficient endogenous enzymes produced by bacteria, the appropriate addition of exogenous enzymes acid proteases can promote the decomposition of proteins in raw materials in an acidic environment, promote the formation of aroma and flavor substances, and shorten the brewing time of soy sauce and vinegar, and improve production efficiency.
2. In the production of meat seasonings with pork, beef, and chicken as raw materials, the addition of papain and flavor enzymes can decompose the protein in meat into small molecular peptides and amino acids. These small molecule peptides and amino acids have a strong flavor and are an important component of many meat seasonings. After the later Maillard reaction, they are nutritionally harmless and have a pure, realistic and full meat flavor with a strong and attractive aroma. This produces specific flavor substances and improves the quality and taste of meat seasonings.
