Embodiment Construction
[0013] A method for preparing high-purity capsanthin from common capsanthin. The process steps are: ① put a certain amount of capsanthin into a supercritical extraction tank; Under the parameters, the capsanthin put into the supercritical extraction tank is extracted, ④ the extracted high-value capsanthin is filtered, and ⑤ the impurities are separated from the capsanthin, which is high-purity capsanthin.
[0014] The amount of capsanthin loaded into the supercritical extraction tank once produced is 6.5kg.
[0015] Described filtration is to filter with 120 mesh stainless steel filter screens.
[0016] The parameters of the supercritical extraction process are that the pressure during the extraction process is 28Mpa, the temperature is 50°C, and the extraction time is 2-3 hours.

The invention discloses a method for preparing a high-purity paprika red pigment from a common paprika red pigment, which comprises the following steps: 1, charging a given amount of paprika red pigment into a supercritical fluid extraction tank; 2, filtering in the process of tank charging; 3, extracting the paprika red pigment charged into the supercritical fluid extraction tank under a certainprocess parameters; 4, filtering the extracted paprika red pigment; and 5, separating impurities form the paprika red pigment to obtain the high-purity paprika red pigment. The method is used for preparing the high-purity paprika red pigment from the common paprika red pigment.
Description
technical field [0001] The invention relates to a preparation method of capsanthin, especially a method for preparing high-purity capsanthin from common capsanthin, which is mainly used in high-grade food, high-grade meat products, high-grade cosmetics, high-grade aquatic products, and pharmaceuticals , advanced feed, etc. Background technique [0002] At present, in the production of high-grade food, high-grade meat products, high-grade cosmetics, high-grade aquatic products, pharmaceuticals, and high-grade feed production, ordinary capsicum red pigment with many impurities, dull color and low light absorption ratio is used. The products produced have poor color, low grade and low added value, which not only affects the entry of products into the high-end market, but also causes low profits and difficulties for manufacturers to survive. Therefore, researching a method for preparing high-purity capsanthin from common capsanthin is a technical problem to be solved at present...
