specific Embodiment approach 1

[0037] Put 51 tons of fresh purple carrots into a drum cleaning machine lined with brushes at a feeding rate of 3 tons per hour for cleaning. The drum speed is 30 rpm and the water flow rate is 6 tons / hour. Cut the cleaned purple carrots into thin strips.

[0038] The purple carrot filaments are sent into the multifunctional extraction tank by the conveyor belt, soaked and extracted with 3 times the citric acid aqueous solution for 4 hours. The collected red pigment solution was filtered to obtain a clear purple carrot pigment solution.

[0039] The clarified purple carrot pigment liquid is filled with an adsorption column of macroporous adsorbent resin, with a column height of 3m and a diameter of 0.8m, filled with 300 kg of macroporous adsorbent resin, and the feed flow rate is 5 kg / min. Washing with pure water at a rate of 25mS / cm, then elution and separation with an aqueous solution containing 60% ethanol, and elution treatment for 16 hours, to obtain 1256 kg of concentra...

Abstract

The invention discloses the preparation method of carotene, which comprises the following steps: (1) cleaning purple carrot and slicing; (2) extracting and filtering; (3) column chromatography; (4) concentrating and ultra-filtering; (5) micro-encapsulating; (6) spray-drying; and (7) sieving and mixing. The invention also discloses a carotene product, which is purple black powder with a color value equal to or larger than 50 and no peculiar carrot smell, and the carotene product is rich in cyanidin, has resistance to light and heat, and is insensitive to the pH value. Compared with the prior art, the invention has the advantage that the carotene preparation method is provided on the premise that ensures product style and internal quality stability and meets the requirement of consumers and has simple process, mild process condition, short preparation cycle, less equipment investment, recycle use of waste water and reuse of waste as feed additives, and the method is suitable for continuous and large-scale industrial production. The carotene of purple carrot has the advantages of low cost, stable quality and high reliability.

Description

technical field [0001] The invention relates to the extraction of carotid pigment, in particular to a preparation method of carotid pigment and a carotid pigment product. Background technique [0002] The color of food is an important sensory indicator of food. In the food industry, synthetic pigments are widely used to increase color. Studies have shown that general synthetic pigments are toxic to varying degrees, and some are even carcinogenic. Therefore, the development of natural and harmless food pigments is of great significance to ensure human health. Carrot (Daucus carrot), also known as carrot or radish, is a biennial herb of the genus Carrot in the family Umbelliferae. The edible part of carrots is the plump and tender fleshy taproot, which has a special sweet taste and is rich in carotene, vitamin C and B vitamins. It has many health functions for the human body, so it is known as "little ginseng". . Native to Southwest Asia, it was introduced into China in the...
