| dc.description.abstractEn | Inactivation of a concentrated threesome of microorganisms (E. coli, S. cerevisiae, L. innocua) in a dietary supplement was investigated using compressed CO2 in batch stirred reactor. Among the operating factors and their range studied through experimental design (20-55 degrees C, 30-170 bar, duration 30-140 min, depressurization rate 30-120 bar/min), temperature had a dominant effect and increased the inactivation as did pressure but in a lesser extent; duration intervened in combination with pressure and depressurization rate had no effect. The influence of the contamination level showed that the treatment was more effective as the microbial load decreased so its duration can be shortened. Total inactivation was achieved for loads up to 10(6) CFU/mL at 100 bar, 38 degrees C, 75 min. The dynamic aspect of CO2 dissolution, theoretically described via gas-liquid mass transfer, showed that dissolution was not a limiting step. Regarding ingredients, polyphenols were fully preserved whereas vitamin C was preserved at similar to 90%. | |
