Problems solved by technology

When the water activity is lower than 0.75, the concentration of reactants should be increased as much as possible, but because the flow transfer of reactants is restricted, the intensity of Maillard reaction will be greatly reduced at low water activity, which will affect the overall flavor formation and umami taste of food , strong taste and other characteristics; when the water activity is greater than 0.85, the reactants are diluted and dispersed in the medium, and the Maillard reaction is not easy to occur
The most suitable conditions for the traditional Maillard reaction are when the water activity is 0.75-0.85, and it takes about 2 hours to complete, which will easily lead to an increase in the content of acrylamide, a harmful by-product at the end of the Maillard reaction.

Abstract

The invention discloses a flavoring essence and a preparation method thereof. The flavoring essence is yellow or brown powdery solid and has flavor similar to traditional barbecue; furthermore, the flavor is stable and can be kept for 6 months or more, and the acrylamide content is lower than 5 mg / kg. The preparation method comprises the following steps: defatted cake meal zymolyte preparation, solubility improving treatment, microwave-assisted treatment, spice compound powder preparation and flavoring essence preparation. According to the preparation method disclosed by the invention, defatted cake meal zymolyte is utilized as a raw material; the defatted cake meal zymolyte is extruded and puffed to change a texture structure, so that solubility of the raw material is improved; under thelow water activity condition, microwave assistance is utilized to improve the strength of maillard reaction, so that the prepared flavoring essence has strong barbecue flavor; furthermore, the flavorcan be stably kept.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a flavor-enhancing essence and a preparation method thereof. Background technique [0002] The complex reaction between reducing sugars in food and amino compounds at a certain temperature is called the Maillard reaction. When the Maillard reaction occurs, a large number of volatile heterocyclic compounds and special volatile flavor substances are produced. It is one of the important sources of food color and aroma. [0003] Seeds of oil crops, such as linseed, peony seeds, walnuts, sunflower seeds, etc., are extracted from oil to leave defatted cake flour. As a by-product of oil extraction, defatted cake flour is often used to process animal feed, defatted cake flour protein The content is very high, using protease hydrolysis, its complex amino acid and short peptide composition can produce a large number of different Maillard products, bringing rich flavor ...
