| Summary: | Natural pigments are one of the most widely used in the food industry. Carotenoids, anthocyanins and betacyanins are among naturally occurring pigments that have always been incorporated into dietary requirements to make them colourful and attractive. The interest in these bioactive constituent pigments lies in the health enhancement effects of the diet. Carotenoids are an excellent source of colouring agent that is acknowledged for their bioactive compounds ability and pro-vitamin A and antioxidant properties. Carotenoids can be produced through various extraction methods, such as chemical extraction, alkaline method, soxhlet, ultrasound, oil extraction, or to more advanced technology such as supercritical fluid extraction. However, the applicability of the extraction methods used is a monumental factor in ensuring product quality. In this study, attention is given to carotenoids, with emphasis on chemical extraction, High-Pressure Processing Unit (HPP) and Supercritical Fluid Extraction (SFE) technologies. Thus, in this review, the advantages and limitations of these natural pigment extraction technology were presented in relation to their physicochemical properties, reactivity and bioactivity. |
