Embodiment 1

[0035] A preparation method of barley extract, specifically comprising the steps of:

[0036] S1. Dry the barley granules in a drying oven at a drying temperature of 60°C; use a pulverizer to pulverize the dried barley granules, and pass through a 220-mesh sieve to obtain dry barley powder; choosing a 220-mesh sieve can ensure that the barley powder The particle size of barley is between 0.06 and 0.07mm. The smaller the particle size of barley, the more effective the dissolution of active ingredients in barley can be ensured. If the particle size is too small, floating powder and leaching will occur, and dry barley will be obtained. pink;

[0037] S2. Add edible organic acid directly to the barley flour for extraction, and use acid treatment to remove the starch in the barley flour; the edible organic acid is citric acid; the acid treatment time is 30min, and the temperature is 35°C; then, in the acidification Add a degreasing agent to the final barley powder solution for deg...

Embodiment 2

[0047] A preparation method of barley extract, specifically comprising the steps of:

[0048] S1. Dry the barley granules in a drying oven at a drying temperature of 70°C; use a pulverizer to pulverize the dried barley granules, and pass through a 220-mesh sieve to obtain dry barley powder; choosing a 220-mesh sieve can ensure that the barley powder The particle size of barley is between 0.06 and 0.07mm. The smaller the particle size of barley, the more effective the dissolution of active ingredients in barley can be ensured. If the particle size is too small, floating powder and leaching will occur, and dry barley will be obtained. pink;

[0049] S2. Add edible organic acid directly to the barley powder for extraction, and use acid treatment to remove the starch in the barley powder; the edible organic acid tartaric acid; the acid treatment time is 40min, and the temperature is 45°C; then, after acidification Add a degreasing agent to the barley powder solution for degreasin...

Embodiment 3

[0059] A preparation method of barley extract, specifically comprising the steps of:

[0060] S1. Dry the barley granules in a drying oven at a drying temperature of 65°C; use a pulverizer to pulverize the dried barley granules, and pass through a 220-mesh sieve to obtain dry barley powder; choosing a 220-mesh sieve can ensure that the barley powder The particle size of barley is between 0.06 and 0.07mm. The smaller the particle size of barley, the more effective the dissolution of active ingredients in barley can be ensured. If the particle size is too small, floating powder and leaching will occur, and dry barley will be obtained. pink;

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...
