Produção de carotenoides por rota biotecnológica empregando substrato a base de amido de batata-doce

Abstract

The consumer market's search for natural products and additives in the food industry has been increasing over the years and as part of this, referring to dye industries, which are looking to replace synthetic products with natural options. Carotenoid dyes are widely studied for their routes to obtain alternatives to synthetics, for using more sustainable raw sciences and promoting them as a current market need. Thus, the present work aims to design an industrial unit for the production of natural carotenoid dye by fermentation route. The choice of the fermentative route, using the microorganism Blaskelea trispora, as among the technological routes was due to its several advantages, such as the use of refuse sweet potato as a substrate and obtaining a natural product. The carotenoids found are commercialized in a concentration of 10% using sweet potato flour incorporated in the industrial unit as a diluent. The industrial unit processes around 925 tonnes of sweet potatoes annually, processing as products to be offered to the market 33 ton/year of 10% (w/w) dye and 200 ton/year of sweet potato flour. The expected annual revenue from the sale of this product will be R$ 25,076,700.00 and R$ 3,311,569.80, respectively, totaling a turnover of approximately R$ 28,388,269.80. With the in-depth economic analysis of the project, it was found that the project is viable and has a profit of R$ 212,988.62 in the first year of operation.
