Kinetics of water absorption of cassava tissues macerated with a microbial polygalacturonase

The objective of the present work was to determine the predictive ability of Pilosof and exponential models to describe water absorption kinetics of cassava tissues macerated with the enzymatic extract of Wickerhamomycesanomalus. Cassava tissues were macerated in Erlenmeyers flasks at 45 ºC, on a ro...

Polygalacturonase Maceration Cassava Water absorption Kinetic Poligalacturonasa Maceración Mandioca Absorción de agua Cinética The objective of the present work was to determine the predictive ability of Pilosof and exponential models to describe water absorption kinetics of cassava tissues macerated with the enzymatic extract of Wickerhamomycesanomalus. Cassava tissues were macerated in Erlenmeyers flasks at 45 ºC, on a rotator shaker (190 rpm), during 1,2 and 4 h, with different extract enzymatic dilutions. Macerated cassava tissues were filtered and dried. A good fit of the experimental data to water absorption models evaluated was obtained. The highest value of C(#) (water concentration at equilibrium) was reached at 1 h of maceration, using undiluted enzymatic extract, with a lower cell damage respect to longer treatments. At higher enzymatic treatment times, water absorption rate constant (K) increased, but C(#) decreased. El objetivo del presente trabajo fue determinar la capacidad predictiva de los modelos de Pilosof y Exponencial, para describir la cinética de absorción de agua de tejidos de mandioca macerados con el extracto enzimático de Wickerhamomycesanomalus. Los tejidos de mandioca fueron macerados en frascos erlenmeyers, a 45 ºC, en agitador rotatorio (190 rpm), durante 1, 2 y 4 h, utilizando diferentes diluciones del extracto enzimático. El tejido macerado fuefiltrado y secado.Se obtuvo un buen ajuste de los datos experimentales a los modelos de absorción de agua evaluados. El mayor valor de C(#) (concentración de agua en el equilibrio) se obtuvo a tiempos de maceración de 1 h, utilizando extracto enzimático sin diluir, con un menor daño celular respecto a los tratamientos efectuados a mayores tiempos. Al aumentar el tiempo del tratamiento enzimático, la constante de velocidad de absorción de agua (K) fue mayor, pero C(#) disminuyó.
