Problems solved by technology

[0004] With the maturity of technology, there are more and more types of thermal reaction flavors, which have attracted the attention of merchants because they can provide a real taste. However, there are few reports on the development of walnut flavors by using thermal reactions. The development of walnuts through thermal reactions using soybean protein as raw material Fragrance has never been reported

Abstract

The invention discloses a walnut-flavored essence and a preparation method thereof. The preparation method comprises the following steps: taking soyabean protein, performing enzymolysis by adding water and protease, then centrifugally collecting supernatant to obtain a proteolysis solution, performing a thermal reaction by adding amino acid, less walnut oil, a solvent and the like, then adding monostearin and xanthan gum, and shearing and homogenizing to obtain the walnut-flavored essence. The walnut-flavored essence is prepared by using the soybean protein as a raw material by combining biological enzymolysis and thermal reaction is excellent in fragrance, taste and high-temperature resistance; the defects of poor fragrance and no heat resistance of a synthetic perfume are overcome.

Description

technical field [0001] The invention belongs to the field of food additives, and in particular relates to a method for preparing walnut essence by means of biological enzymolysis and thermal reaction. Background technique [0002] Currently, the walnut flavors on the market are still mainly composed of synthetic monomeric fragrance raw materials, which lack taste and have general heat resistance. [0003] my country is rich in soybean protein. Compared with raw materials such as walnut meal, its source is wider and its output is higher. It is a high-quality protein source. If it is used properly, it can develop flavor products with high added value. [0004] With the maturity of technology, there are more and more types of thermal reaction flavors, which have attracted the attention of merchants because they can provide a real taste. However, there are few reports on the development of walnut flavors by using thermal reactions. The development of walnuts through thermal reac...
