Problems solved by technology

This process requires the use of organic solvents, resulting in a large loss of color value during concentration and high processing costs
In the patent with the publication number CN102675911B, the mixed solution of capsanthin plus phosphoric acid and ammonia water is hydrated and then centrifuged multiple times. The process is relatively complicated, and a large amount of high-salt wastewater that is difficult to treat will be generated.

Abstract

The invention discloses an industrialized method for improving capsanthin quality by continuous centrifugal treatment. The industrialized method comprises the following steps: (1) performing heating treatment on capsanthin in a blending tank, and then storing in a refrigeration house to separate out a precipitate; (2) sucking the capsanthin which is stored at a low temperature into the blending tank, and stirring uniformly; (3) performing centrifugal treatment on the capsanthin which is stirred uniformly through a clarifying-type disc centrifugal machine, wherein light phase liquid which is subjected to the centrifugal treatment is high-quality capsanthin. The industrialized method is easy to operate, low in chroma loss, and suitable for large-scale industrial production; a chemical reagent is not used; the treated high-quality capsanthin is high in fluidity; the precipitate is less than or equal to 0.8 percent; an acetone insoluble matter is less than or equal to 0.5 percent.

Description

technical field [0001] The invention relates to an industrialized method for refining capsanthin, in particular to an industrialized method for continuously centrifuging to improve the quality of capsanthin. Background technique [0002] Capsanthin has bright color, strong coloring ability, good stability, high safety, and certain nutritional and health functions. It is an excellent natural oil-soluble pigment and is widely used in food, medicine, feed and other fields. [0003] As a natural extract, capsanthin will be mixed with impurities such as phospholipids, polysaccharides, and proteins during the extraction process. At present, the capsanthin produced by the conventional process often has high sediment and acetone insoluble matter, which affects the use of customers. [0004] Centrifugation is a conventional means to remove impurities in materials. However, due to the particularity of capsanthin, when the temperature is high, most of the impurities will dissolve int...
