Example Embodiment

[0034] Example 1

[0035] A preparation method of barley extract specifically includes the following steps:

[0036] S1. Place the barley grains in a drying box for drying at a drying temperature of 60℃; use a pulverizer to crush the dried barley grains, and pass through a 220-mesh sieve to obtain dried barley flour; choose a 220-mesh sieve to ensure the barley flour The particle size of the barley is between 0.06mm and 0.07mm. The smaller the particle size of the barley, the more effective the active ingredients in the barley can be dissolved. If the particle size is too small, the floating powder and extraction will occur, and the dried barley can be obtained. powder;

[0037] S2. The edible organic acid is directly added to the barley powder for extraction, and the starch in the barley powder is removed by acid treatment; the edible organic acid is citric acid; the acid treatment time is 30 minutes and the temperature is 35°C; A degreasing agent is added to the later barley powd...

Abstract

The invention relates to a preparation method of a coix seed extract. The method comprises the steps as follows: S1, drying and crushing coix seeds to obtain coix seed flour; S2, removing starch and fat in the coix seed flour through acid treatment and addition of a degreasing agent; S3, performing dynamic superhigh-pressure microfluidization treatment on coix seed pulp to promote dissolution extraction of polysaccharide and protein in the coix seed pulp; S4, adjusting the mass concentration of the coix seed pulp, adding an ionic strength regulator to regulate the ionic strength of the coix seed pulp, and adjusting the pH of the coix seed pulp; S5, adding an organic polymer adsorbent to the coix seed pulp to adsorb protein and polysaccharide agglomerates; S6, performing standing and filtration, collecting a filtered-out organic polymer adsorbent, and sequentially eluting polysaccharide and protein; and S7, removing starch and grease again through low-temperature settlement and centrifugal degreasing to finally prepare a coix seed emulsion containing polysaccharide and protein. The prepared coix seed emulsion is compounded into instant compound coix seed flour.

Description

technical field [0001] The invention belongs to the technical field of food processing and the field of extraction and processing of plant active substances, and in particular relates to a preparation method and application of barley extract. Background technique [0002] Job's tears, also known as Job's tears and Job's tears, are the seeds of the 1-year or perennial herb Job's tears. Barley is mostly grown in mountainous areas, and has a long history of cultivation in Fujian. Ancient people regarded barley as a treasure of nature and used it for sacrifices; modern people regard barley as a nutritious midsummer refreshing product, which can be eaten or used as medicine. Barley is rich in protein, high in carbohydrates and fat, and also rich in polysaccharides, B vitamins and various minerals. It has various effects such as lowering blood sugar, anti-cancer, and promoting immune regulation. However, at present, barley is mainly sold as raw rice, the level of development and...
