“…Algumas espécies de bactérias, fungos, algas e plantas superiores são capazes de produzir estes pigmentos. 8 Em animais, como crustáceos (camarão, lagosta, siri), aves (flamingo) e peixes (truta e salmão), 10,11 esses pigmentos são acumulados no organismo por meio da alimentação.…”

“…11 A produção de carotenoides por síntese química foi iniciada em 1954, com a produção comercial de β-caroteno pela Hoffmann-La Roche. Seguiu-se a p odução de β-apo-'-carotenal em 1960 e, em 1965, teve início a produção de cantaxantina pela mesma indústria.…”

Abstract:The increase of natural products demand has motivated the replacement of artificial colorants for natural ones, because, according to some researches, the consumption of artificial pigments can cause health damage. Carotenoids are natural lipophilic pigments, which can present the colors yellow, orange or red. They are widely distributed in nature in algae, plants, crustaceans, fishes, birds and microorganisms. These colorants can be applied in several kinds of industries, not only with the purpose of coloring, but also to enrich foods and even as food supplement components, animal feed, pharmaceuticals and cosmetics. In face of the carotenoid demand, it is estimated that the world market will move substantial amounts of money in the coming years. Considering this fact, in the Brazilian scenario, there can be an increase in imports, while the exports may remain as the last six years, with small changes, since in Brazil there are no investments on technology development for carotenoid production.Keywords: Natural colorants; carotenoids; carotenoids properties; carotenoids applications; carotenoids market. ResumoA crescente busca por produtos naturais tem motivado a substituição de corantes artificiais por naturais, pois segundo alguns estudos, o consumo de corantes artificiais pode causar danos à saúde. Os carotenoides são corantes naturais, lipofílicos, com coloração amarela, laranja ou vermelha e se encontram amplamente distribuídos na natureza em algas, plantas, crustáceos, peixes, aves e microorganismos. Esses pigmentos podem ser aplicados em diversas indústrias, não somente com a finalidade de colorir, como também para enriquecer alimentos e até mesmo compor suplementos alimentares, rações, fármacos e cosméticos. Diante do aumento da demanda por carotenoides, estima-se que o mercado mundial movimentará vultosas quantias nos próximos anos. Considerando este fato, no cenário nacional, pode haver a elevação das importações, enquanto as exportações poderão se manter como nos últimos seis anos, com valores irrisórios, uma vez que são escassos os investimentos no desenvolvimento tecnológico de produção de carotenoides no Brasil.

“…They are considered bioactive compounds due to their antioxidant capacity, since they neutralize free radicals through the reception of electrons from reactive species (Valduga et al, 2009a;Gonnet et al, 2010). Although these pigments are found in plants, animals and microorganisms, most carotenoids destined to the food industry are obtained by chemical processes (Valduga et al, 2009b), a fact that suggests growing interest in studies of carotenoid production by biotechnological processes (Valduga et al, 2009a).…”

Microencapsulation by lyophilization of carotenoids produced by Phaffia rhodozyma with soy protein as the encapsulating agent

Carotenoids are pigments that can be applied to food but they are unstable towards certain food intrinsic conditions, as well as processing ones. Microencapsulation is an alternative to increasing their stability. This study aimed to produce carotenoids by Phaffia rhodozyma crops and promote their microencapsulation by lyophilization with soy protein as the wall material, in different proportions. High process yield of 96% and encapsulation efficiency of around 65% were observed at the ratios under study. Well-defined and separate micrometer-scale particles with different shapes and sizes were formed and the protection of the compounds of interest was confirmed by differential scanning calorimetry which showed that the endothermic eventtypical of the free extract after encapsulation -did not occur.Keywords: pigments; microbial cultures; microcapsules.Practical Application: Microcapsules protecting microbial carotenoids that allow the application in food.

RESUMO: O β-caroteno é um carotenoide que faz parte do grupo das vitaminas lipossolúveis. É essencial para o ser humano e é encontrado nos alimentos de origem vegetal como pró-vitaminas ABSTRACT: β-carotene is a carotenoid that is part of the group of fat-soluble vitamins. It is essential for humans and is found in foods of plant origin as pro-vitamins A. It is a carotenoid that exhibits antioxidant action due to its conjugated double bonds, which are susceptible to oxidation under the action of light or oxygen.Macauba is a fruit rich in bioactive compounds containing about 45% of pulp. The present work aimed at the extraction of β-carotene from the macaúba pulp with different solvents such as: n-hexane, petroleum ether and acetone. The process of extraction of the total carotenoids was based on the procedure described by RODRIGUEZ-AMAYA (2001)
