Natural pigments are viable to replace synthetic dyes in the food industry. In this paper, a comprehensive review of appropriate pretreatment and extraction methods for chlorophylls, carotenoids, betalains, and anthocyanins, which are major classes of plant. However due to time consumption and high volume of.
Promising extraction techniques are introduced. This review aims to investigate the extraction of carotenoids from a variety of natural sources, including marine sources like fungus, microalgae, and crustaceans, as well as widely studied. The impact of the extraction technologies on product yield and analytical profile is relevant.
They are utilized to restore or enhance the colour of processed foods. Brazil has several species of exotic fruits with a high potential source for pigments.
