Abstract

The invention discloses a high-concentration fermented milky flavor base, and a preparation method and application thereof. The preparation method comprises the following steps of: (1), dissolving full-fat milk powder, dried skim milk powder or mixture of both, and anhydrous cream in water, to obtain high-concentration reconstituted milk; (2), homogenizing the obtained reconstituted milk, hydrating, sterilizing and cooling; (3), adding a lactic acid bacteria starter and enzyme preparation in the reconstituted milk obtained in the step (2), then fermenting and carrying out enzymolysis, to obtain high-concentration fermented milk base; and (4), milling the obtained fermented milk base by a colloid mill, homogenizing, sterilizing while stirring and finally cooling to normal temperature, so as to obtain the high-concentration fermented milky flavor base. In the flavor base, the protein content is between 5% w / w and 10% w / w, the titration acidity is between 250 degrees T and 450 degrees T, and the amino acid nitrogen content is 0.11g / 100mL at least; and the high-concentration fermented milky flavor base has the advantages of relatively high acidity, rich aroma and natural, mild and abundant fermented flavor, and can be used for aroma enhancement of baked foods.

Description

technical field [0001] The invention belongs to the field of food fragrance bases, and in particular relates to a high-concentration fermented mastic base, a preparation method thereof and an application in increasing the flavor of baked food. Background technique [0002] Milk flavor base is one of the most widely used flavor bases in baked goods. At present, the methods for preparing milk flavor base mainly include chemical method and biological method. Among them, the biological method refers to the natural milk-flavored fragrance base made by using relevant microorganisms, enzyme hydrolyzed butter and other biological technologies and then modified and formulated, which has the characteristics of natural and soft aroma. This is incomparable to similar milk flavor bases formulated from single spices. At the same time, as people put forward higher requirements for the aroma and safety of milk-flavored bases, the development of natural milk-flavored base series products h...
