Problems solved by technology

Since the main components of grain aroma are divided into water-soluble and alcohol-soluble, polar and non-polar, simple water extraction is difficult to restore the aroma of the grain itself, resulting in a thin and uncoordinated aroma.
Although the content of certain aroma components is small, its threshold value is low, which has a very important impact on the senses

Abstract

The invention discloses a preparation method for a grain extracting solution. The preparation method comprises the steps of baking grains as raw materials, quickly cooling and grinding, and further comprises the steps as follows: a), mixing the ground grains with an organic water solution, extracting in a nitrogen environment, and recovering a condensed solution; and b), carrying out vacuum concentration on the condensed solution to obtain the grain extracting solution. Compared with the prior art, the aroma constituents of the grains are extracted by the organic water solution, and the extraction process is proceeded in the nitrogen environment, so that the effective constituents are effectively prevented from being oxidized and destroyed to guarantee the completeness of the aroma constituents so as to enable the extracting solution to be able to recover full aroma of the grains.

Description

[0001] technical field [0002] The invention relates to the technical field of food processing, in particular to a method for preparing a grain extract. [0003] Background technique [0004] The National Industrial Structure Adjustment Guidance Catalog regards cereal beverage products as one of the guiding directions for product reform. In beverage production, the extraction of baked grain raw materials is consistent with the extraction method of tea beverage raw materials. At present, the method of spraying at about 85°C is mostly used. Since the main aroma components of grains are divided into water-soluble and alcohol-soluble, polar and non-polar, simple water extraction is difficult to restore the aroma of the grain itself, resulting in a weak and uncoordinated aroma. Although the content of certain aroma components is small, its threshold is low, which has a very important impact on the senses. In order to highlight the concept of green, natural and healthy, cereal...
