Abstract:

Color of a food substance is important to indicate its freshness and safety that are also indices of good aesthetic and sensorial values. In the recent years, coloring of food with pigments produced from natural sources is of worldwide interest and is gaining importance. Naturally derived pigments are represented by carotenoids, flavonoids and some tetrapyrroles. Lately, interest in synthetically derived pigments has decreased due to their toxic, carcinogenic and teratogenic properties and attention towards microbial sources has increased as a safe alternative. Several species of algae, fungi and bacteria have been exploited commercially for the production of natural pigments. In this Carotenoids represent one of the most widely distributed and structurally diverse classes of natural pigments. Carotenoids are ubiquitous pigments synthesized by plants, fungi, algae and bacteria. Microorganisms can serve as sources of carotenoids, the most widespread group of naturally occurring pigments. The carotenoid production through chemical synthesis or extraction from plants is limited by low yields that results in high production costs. This leads to research of microbial production of carotenoids as an alternative that has shown better yields than other aforementioned. In addition, the microbial production of carotenoids could be a better option about costs, looking for alternatives like the use of low-cost substrates as agro-industrials wastes. Agro-industrial wastes provide carbon and nitrogen source necessary and others elements to carry out the microbial metabolism diminishing the production costs and avoiding pollution from these agro-industrial wastes to the environment. Industrially, carotenoids are used in pharmaceuticals, neutraceuticals and animal feed additives as well as colorants in cosmetics and foods. Scientific interest in dietary carotenoids has increased in recent years because of their beneficial effects on human health such as lowering the risk of cancer and enhancement of immune system function which are attributed to their antioxidant potential and also to the growth of certain areas such as agriculture, especially aquaculture and poultry industry.
