“…C. tropicalis CCTCC M2012462 was able to produce xylitol with yields of 0.72 g/g of consumed xylose; however, this was only after 60 hr of fermentation and in a medium containing corn straw biomass hydrolysate with only 3.93 g/L acetic acid (Wang, Ling, & Zhao, ). The xylitol concentration values obtained are higher than those found by Jia et al (), who obtained 0.77 g/g of consumed xylose and productivity of 2.45 g·L·h after 40 hr of fermentation, using corncob hydrolysate as substrate. They are also higher than the value found by Vallejos et al (), who achieved a maximum xylitol production of 0.57 g/g, after 120 hr, produced by C. tropicalis in liquor obtained from sugarcane bagasse with 1.39 g/L acetic acid.…”

Xylitol is a building block for a variety of chemical commodities, besides being widely used as a sugar substitute in the food and pharmaceutical industries. The aim of this work was to develop a microbial process for xylitol production using sugarcane bagasse hydrolysate as substrate. In this context, 218 non-Saccharomyces yeast strains were screened by growth on steam-exploded sugarcane bagasse hydrolysate containing a high concentration of acetic acid (8.0 g/L). Seven new Candida tropicalis strains were selected and identified, and their ability to produce xylitol on hydrolysate at low pH (4.6) under aerobic conditions was evaluated.The most efficient strain, designated C. tropicalis JA2, was capable of producing xylitol with a yield of 0.47 g/g of consumed xylose. To improve xylitol production by C. tropicalis JA2, a series of experimental procedures were employed to optimize pH and temperature conditions, as well as nutrient source, and initial xylose and inoculum concentrations. C. tropicalis JA2 was able to produce 109.5 g/L of xylitol with a yield of 0.86 g/g of consumed xylose, and with a productivity of 2.81 g·L·h, on sugarcane bagasse hydrolysate containing 8.0 g/L acetic acid and177 g/L xylose, supplemented with 2.0 g/L yeast nitrogen base and 4.0 g/L urea. Thus, it was possible to identify a new C. tropicalis strain and to optimize the xylitol production process using sugarcane bagasse hydrolysate as a substrate. The xylitol yield on biomass hydrolysate containing a high concentration of acetic acidobtained in here is among the best reported in the literature.

“…Chemical methods for xylitol production can be carried out through several stages, including hemicellulose extraction, hydrolysis of hemicellulose to xylose, and hydrogenation of xylose to xylitol [2]. The extraction of hemicellulose components can be conducted using Tetrabutylammonium hydroxide (TBAH) [20]. Hemicellulose-rich material mixed with TBAH then agitated at 50-70 °C for 60-120 minutes, then centrifuged.…”

Xylitol is a type of alcohol sugar that is often used in various pharmaceutical and food industries. Xylitol can be produced from raw materials that contain lots of hemicelluloses. Hemicellulose is commonly found in various agricultural wastes such as bagasse, corncobs, oil palm bunches, and others. This review discusses various methods for xylitol production. In general, the production of xylitol uses chemical and biotechnological processes. Chemical production is generally carried out by hydrolysis using chemical catalysts or metals, while the biotechnological production is carried out by enzymatic and fermentation utilizing the role of microorganisms. Xylitol production in biotechnological methods has been developing rapidly to replace chemical production because xylitol yields are high and are environmentally friendly.

“…Entre os edulcorantes, o xilitol é um poliol de cinco carbonos, que é produzido por meio da hidrogenação química da xilose a nível comercial (Pal et al, 2016), que pode ser empregado em alimentos e bebidas na quantidade necessária para se atingir o sabor esperado (BRASIL, 2017). É um adoçante de baixo valor energético, e tem sido popularmente utilizado na preparação de vários produtos alimentícios e de confeitaria, como goma de mascar sem açúcar e produtos de panificação (Jia et al, 2016). O mercado consumidor tem se interessado por produtos reduzidos em sacarose, diversificados e elaborados com diferentes matérias-primas, tornando necessário a pesquisa por novos produtos.…”

Geleia é o produto elaborado utilizando frutas com adição de açúcar (sacarose), pectina e ácido, além de outros ingredientes. É de interesse a diversificação dos sabores deste produto, bem como o aproveitamento de subprodutos agroindustriais. O objetivo deste trabalho foi elaborar e caracterizar geleias mistas de uva e maracujá nas formulações tradicional, light e diet. As amostras obtidas foram caracterizadas quanto aos parâmetros físico-químicos, potencial antioxidante, estabilidade durante 45 dias de estocagem, e aceitabilidade sensorial. Para as formulações tradicional, light e diet os teores de sólidos solúveis foram de 69,67; 45,03 e 32,10 °Brix, os valores de pH variaram de 3,64 a 3,66 e os teores de umidade foram de 27,99; 55,08 e 65,63%, respectivamente. A formulação tradicional apresentou maior teor de compostos fenólicos totais (33,38 ± 0,75 mg 100g-1), seguida da formulação light (15,32 ± 0,17 mg 100g-1) e diet (9,79 ± 3,14 mg 100g-1). As formulações tradicional e light apresentaram maior aceitação sensorial. Durante o período de armazenamento não houve alteração nos valores de acidez, porém ocorreu aumento no teor de umidade e modificações na cor para todas as formulações. Os resultados mostraram o uso promissor da mistura das frutas uva e maracujá para elaboração de geleias com redução de açúcar.
