Problems solved by technology

[0003] The disadvantage of this extraction process is: when stirring intermittently, the beet pigment is in contact with light for a long time, which is easy to oxidize, thereby reducing the color value of the pigment; the traditional extraction with water has a long extraction time, a large amount of water, and a high temperature, so , the process time is long, the production cycle is long and the color value of the pigment is seriously lost

Embodiment Construction

[0013] The present invention will be described below in conjunction with the embodiments.

[0014] The beet pigment extraction process of the present invention of the present invention, its production process is: clean beet, remove other foreign matter; Put into grinder and beat, add 0.3% citric acid water to beat together, beet and citric acid water The ratio is 1:1; through the plate filter, filter directly into the storage tank; on the resin column, the ratio of resin quantity to raw beet is 1:16; wash with water to remove some impurities adsorbed on the surface of the resin; use 60% alcohol for analysis After analyzing the concentrated solution, add 0.04% antioxidant to protect it; use an external circulation concentrator to recover alcohol and concentrate it; put it into a spray drying tower to spray it into a powder product.

[0015] Compared with the prior art, the beet does not need to be stirred and is directly beaten, thus avoiding long-term contact of the sugar beet...

Abstract

The invention discloses an extraction process of a beet pigment. The extraction process comprises the following steps of: adding water and pulping a cleaned beet raw material; filtering with a plate frame; performing column chromatography on filtered liquor; and finally resolving with edible alcohol, recovering, concentrating, and spraying by using a spray drying tower to finally obtain a product. According to the extraction process, by adding a small amount of water, pulping and directly filtering, the extraction process has the advantages of short process time, less color value loss and the like, and is particularly suitable for extraction of the beet pigment.

Description

technical field [0001] The invention relates to a pigment extraction process, in particular to a beet pigment extraction process. Background technique [0002] Beet red is an edible red pigment extracted from the roots, stems and leaves of red beets. It is one of the most widely used natural pigments in the world. To extract beet red pigment from red beet, usually first trim and wash the red beet, add water according to a certain proportion, stir intermittently, put the extract into a juicer to squeeze the juice and filter, and the filtrate is absorbed by the adsorption column, Alcohol analysis to obtain beet red concentrated liquid; then, add a certain amount of antioxidants to the beet red concentrated liquid, then concentrate through ultrafiltration membrane, after reaching a certain concentration, add a certain amount of antioxidants to carry out vacuum decompression Concentrate and then spray dry to get the finished pigment. [0003] The disadvantage of this extractio...
