Abstract

The invention discloses a butter fat enzymolysis product and a preparation method and application thereof. The preparation method comprises the following steps: (1) sterilizing single cream, adding lipase into the sterilized single cream to be evenly mixed to form a mixture, performing enzymolysis under the stirring or oscillating condition, or adding an emulsifying agent into the single cream to perform emulsification and then perform sterilization, adding the lipase into the mixture to be evenly mixed, and performing the enzymolysis under the standing condition or under the stirring or oscillating condition, and (2) heating the enzymolysis product obtained by means of the step (1) to kill the lipase. The invention further provides the application of the butter fat enzymolysis product in food preparation, and the butter fat enzymolysis product can be applied to foods including milk-flavored food, cream-flavored food, cured food and dairy products with related flavor and the like. The butter fat enzymolysis product can have the effects of enhancing product characteristic aromas and sensory characteristics of different production batches of standardized products under the condition that any food additive is not added.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to a method for preparing a milk fat enzymatic hydrolysis product, the milk fat enzymatic hydrolysis product obtained by the preparation method and its application. Background technique [0002] The sensory quality of food promotes food consumption. However, as food health is getting more and more attention today, consumers are pursuing more and more senses, but reject the addition of unnatural substances. Therefore, it is an inevitable trend to utilize methods such as biotechnology to obtain natural flavor substances. It is still difficult for chemically synthesized milk flavors to simulate the creamy aroma in detail, while natural milk flavors are much superior in aroma, especially in the field of baking. The milk-flavored flavor prepared by using relevant microorganisms, enzyme hydrolyzed cream and other biotechnological means has a natural and soft aroma. However, in addition t...
