Problems solved by technology

The content of PAHs in capsicum red products produced by traditional technology reaches more than 100ppb, and the single item of benzopyrene reaches more than 30ppb, which is far from meeting the requirements of PHAs<50ppb and benzopyrene<10ppb
If the content of polycyclic aromatic hydrocarbons is not effectively controlled, it will inevitably affect the development of the industrialization of capsicum red in the future
At present, there are no relevant literature reports on the control of polycyclic aromatic hydrocarbons in capsanthin, and it is impossible to achieve the purpose of effectively separating polycyclic aromatic hydrocarbons under the premise of ensuring the yield of capsanthin

Abstract

The invention discloses a production method of low polycyclic aromatic hydrocarbon capsanthin. The method comprises the following steps: drying capsicum, pulverizing, granulating, leaching, and filtering to obtain a capsanthin leachate; carrying out dynamic liquid-liquid extraction pungency removal on the pigment leachate , and adsorbing with a low-pressure chromatographic column to obtain a low-benzopyrene pigment solution; and concentrating the low-benzopyrene pigment solution to obtain the low-benzopyrene capsanthin product. A low-pressure chromatographic column process is adopted for the first time to remove benzopyrene from a capsanthin leaching pungency-removing solution in a dynamic adsorption mode in the extraction process, so that the purpose of removing benzopyrene is achieved, and meanwhile, based on the fact that the adsorption rate of capsanthin by a chromatographic column used in a solvent is extremely low, the yield of capsanthin is not remarkably influenced. A physicaladsorption mode is adopted, so that the change of the properties of the product caused by introduction or chemical treatment of exogenous substances is avoided; and meanwhile, the process flow is simplified, the operation is simple, the cost is low, industrial production is facilitated, and reference is provided for control of natural pigment safety indexes.

Description

technical field [0001] The invention belongs to the technical field of refining food additives, and in particular relates to a production method of capsanthin with low polycyclic aromatic hydrocarbons. Background technique [0002] Paprika red pigment is a natural red pigment extracted from the peel of ripe red peppers, and its main components are capsanthin, capsorubin, β-carotene and Zeaxanthin, etc., whose color intensity is 10 times that of other pigments, is widely used in food, beverage, cosmetics and pharmaceutical industries, and is internationally recognized as the best class A red pigment. Capsanthin is the bright red part of red peppers. [0003] The main preparation process of traditional capsanthin: dry and pulverize capsicum, use solvent extraction method to obtain the crude extract of capsanthin, then use lye or ethanol and other solvents to extract and remove spicy substances, and distill out the Solvent to obtain refined capsanthin. [0004] With the cont...
