Rendimiento de manano en la corriente secundaria de obtención de b-1,3-glucano

The yield of the mannan obtained in the basic supernatant of the glucan process from Saccharomyces cerevisiae was evaluated. The basic supernatant was kept at temperatures of 5 ± 3 °C and 27 ± 3 °C during 90 days. The levels of carbohydrates and proteins were also determined. The best yields were obtained in the supernatant kept up to 45 days at temperatures from 2 to 8 °C, and for only 24 h at temperature from 24 to 30 °C. The yield and the product characteristics were significantly affected at higher times. No significant differences (p < 0,05) in the concentration assessment of the total carbohydrates and proteins were observed. Key words: glucano; mannan; prebiotic; Saccharomyces cerevisiae.
