Problems solved by technology

[0003] Cabbage has a unique odor, and the details of the production process of each enterprise are different. Some enterprises do not inactivate enzymes when producing cabbage red pigment, or inactivate enzymes insufficiently, and remove impurities during the production process. Due to the above reasons, the produced cabbage Red pigments often have a relatively strong odor and give customers a poor first sensory impression, which severely limits their sales, promotion and application

Embodiment 1

[0008] Example 1: Take 20.0L of liquid cabbage red pigment with peculiar smell as raw material, add 40L of butane solvent, add 0.1L of ether, keep stirring at 80rpm for 30min, mix well, raise the temperature to 35°C and keep it, let it stand for extraction for 1 hour . Under airtight conditions, the temperature was kept at 40°C to recover the solvent and remove the solvent residue to obtain 19.83L of liquid cabbage red pigment with no peculiar smell and good water solubility. After the product is sterilized, it can be spray-dried to obtain powdered cabbage red pigment, and the product has no peculiar smell.

Embodiment 2

[0009] Example 2: Use 20.0L of liquid cabbage red pigment with peculiar smell as raw material, add 60L of butane solvent, add 0.05L of ether, keep stirring at 80rpm for 40min, mix well, raise the temperature to 35°C and keep it, let stand for extraction for 1 hour . Under airtight conditions, the temperature was kept at 40°C to recover the solvent and remove the solvent residue to obtain 19.66L of liquid cabbage red pigment with no peculiar smell and good water solubility. After the product is sterilized, it can be spray-dried to obtain powdered cabbage red pigment, and the product has no peculiar smell.

Abstract

The invention relates to a method for removing peculiar smell of red cabbage through solvent treatment. The liquid red cabbage can be used for preparing powder products with no peculiar smell through spray drying, belonging to the technical field of natural pigment refining. The method comprises the following steps: (1) mixing: adding liquid red cabbage with peculiar smell into a retort; adding extracting solvent butane and refining assisting agent ethyl ether with low boiling point and strong volatility, fully stirring and mixing evenly; (2) extracting: heating the mixture to 20-40 DEG C, standing, extracting for 0.5-2 hours; (3) concentrating, removing smell, preserving the temperature of 20-45 DEG C under closed condition, recovering extracting solvent and refining assisting agent, fully removing extraction solvent residue to obtain liquid red cabbage with the peculiar smell being removed; and (4) pulverizing: carrying out spray drying on the liquid red cabbage to obtain the powderred cabbage with the peculiar smell being removed. Liquid and power red cabbage obtained by the method has no peculiar smell, good water solubility and low process cost.

Description

technical field [0001] The invention relates to a method for removing peculiar smell in liquid cabbage red pigment by solvent treatment. The liquid cabbage red pigment can be spray-dried to prepare a powder product without peculiar smell, and belongs to the technical field of natural pigment refining. Background technique [0002] Cabbage red is a natural pigment with natural color and moderate tone. It has a variety of nutritional and functional components. It is a widely used edible natural pigment. The traditional preparation method is to use the leaves of the cruciferous plant purple cabbage, extract with weakly acidic water, remove impurities and concentrate to obtain liquid cabbage red pigment, and then undergo sterilization and spray drying to obtain a powder product. [0003] Cabbage has a unique odor, and the details of the production process of each enterprise are different. Some enterprises do not inactivate enzymes when producing cabbage red pigment, or inactivat...
