Abstract

The invention discloses a beef-flavor yeast extract and a preparation method thereof. The method comprises the following steps: adding water into beef to prepare beef pulp, homogenizing through a colloid mill, deactivating enzyme and cooling; and carrying out two-stage enzymolysis on the beef pulp by using alkaline protease and flavourzyme, and carrying out enzyme deactivation treatment after thetwo-stage enzymolysis is finished; Heating to melt the beef tallow, introducing quantitative air, and stirring to react for 3-4 hours to prepare oxidized beef tallow; adding the yeast extract, the beef enzymatic hydrolysate, the oxidized beef tallow and the like into a thermal reaction device, heating to react, cooling to room temperature, and concentrating in vacuum, thereby obtaining the product. According to the process disclosed by the invention, various flavor substances and thermal reaction flavor precursor substances such as micromolecular alcohols, aldehydes, ketones and esters in theraw materials can be effectively stimulated, and a product interacting with the Maillard reaction can have strong beef flavor aroma, so that a foundation is laid for providing beef characteristic flavor for the beef-flavor yeast extract; and after the beef pulp is decomposed by alkaline protease and flavourzyme, the finally prepared extract beef is rich in flavor, sufficient in delicate flavor andwide in application field.

Description

technical field [0001] The invention relates to the field of food, in particular to a method for preparing beef-flavored yeast extract and the beef-flavored yeast extract prepared by the method. Background technique [0002] As a food ingredient, yeast extract has been widely used in instant noodles, meat products, seasonings and other industries. Yeast extract has a bouillon aroma, but the characteristic flavor is not obvious. The United States, Japan, Germany and other countries have carried out thermal reaction research on meat-flavored flavorings, but there are no research reports on yeast extract-related products with obvious characteristic flavors. Since the early 1960s, many researchers have reported that the non-volatile precursors of the aroma of cooked meat are water-soluble components extracted from raw muscle. Body substances include amino acids, peptides, reducing sugars (especially glucose, fructose, and ribose) and nucleotides (especially disodium 5′-inosina...
