For this purpose, osmotic dehydration was carried out using two ternary solutions: stevia-salt-water (S1) and glucose-salt-water (S2) at different concentrations (20%, 30% and 40% w/w), and processing times of 40 min, 80 min, 120 min, and 160 min. Also, the diffusion coefficient was determined and the analysis of variance with orthogonal polynomials was performed to find the best treatment for dehydration of auyama samples (p≤0.05). The results suggest that the solution constituted by stevia-salt-water, allows greater reduction of weight and gain of solids when a concentration of 40% is used at a time of 78.12min until reaching a humidity percentage of 60.06%. Similarly, the values of the diffusion coefficient for this solution ratify that the increase in concentration generates less resistance to mass transfer. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49662418014 https://www.redalyc.org/journal/496/49662418014/ https://www.redalyc.org/journal/496/49662418014/html/ https://www.redalyc.org/journal/496/49662418014/49662418014.epub https://www.redalyc.org/journal/496/49662418014/movil 10.15446/dyna.v86n209.72895 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.209 Vol.86 |
