Characteristics of the existing methods for the production of carotenoids from vegetable raw materials and secondary resources of its processing

Abstract

Carotenoids, in particular, beta-carotene and lycopene, have high antioxidant properties and are used to prevent and treat various diseases associated with human aging. The search for new or intensification of the existing methods of their preparation from plant raw materials and the secondary resources of its processing is relevant due to the high demand for carotenoids in the food, cosmetic and pharmacological industries. The purpose of the research is to analyze the patent information for determining the most optimal and promising directions in the technology of obtaining carotenoids from vegetable raw materials. The main method of obtaining carotenoids from vegetable raw materials and secondary resources of its processing is their extraction using organic solvents. Domestic and foreign scientists have been conducting scientific research in the field of intensification of the process of extraction of carotenoids from vegetable raw materials and secondary resources of its processing in order to increase the environmental safety of the technological process and the quality of the product obtained. Various technical solutions have been proposed on pre-processing of the feedstock using ultrasound (US) effects and microwave radiation, as well as enzymes and enzyme preparations for carotenoids. Analysis of foreign and domestic patent information has shown that studies in the field of integrated use of physical (ultrasound and microwave radiation) and biotechnological (enzymes and enzyme preparations) of pretreatment of the initial raw materials are most promising to increase the efficiency of the extraction of carotenoids from vegetable raw materials and secondary resources of its recycling.
