Summary: | When multi-effect evaporators (EME) are implemented at the process of panela —besides of technological adjustment— to maintain the quality of the product is also required. This state unveiled a technology gap,and issues such as the contribution of compositional differences in the varieties of cane on panela. To fill part of this technological gap, the objective of this work is to determine the effect of pressure evaporation and the varieties of cane on quality of honey and panela. To achieve this, the evaporation pressure and sugarcane varieties in one experimental design completely randomized with 4x3 factorial arrangement and four replications was implemented: varieties CC 85-46, RD 75-11 and PR 61-632, without flocculant, without coadjuvant and was evaporated with a heat flux of 27,778 kW/m2 and without antifoam. The results showed a similar behavior for the studied sugarcane varieties. So honeys and panelas in the pressurized system presented dark coloration, reddish tone, high turbidity, a glycoside coefficient between 60 % and 70 % and they did not solidified.Honeys and panelas in vacuum systems presented a reater turbidity, clear colorations, yellowish tones, and good solidification and coefficients glycosides under 12 %.
Al implementar el uso de evaporadores múltiple efecto (EME) al proceso panelero, además del ajuste tecnológico, se requiere mantener la calidad del producto. Esta condición develó el desconocimiento de aspectos como el aporte de las diferencias composicionales en las variedades de caña a las características de la panela. A fin de llenar parte de este vacío tecnológico, el objetivo del trabajo que aquí se presenta fue determinar el efecto de la presión de evaporación y la variedad de caña sobre la calidad de la panela. Para lograrlo, se trabajó la presión de evaporación y la variedad de caña en un diseño experimental completamente al azar con arreglo factorial de 4x3 y cuatro repeticiones, las variedades CC 85-46, RD 75-1 y PR 61-632, sin floculante, coadyuvante, ni antiespumante y una densidad de flujo calórico en evaporación de 27,778 kW/m2. Los resultados mostraron un comportamiento similar para las variedades estudiadas. Así, las mieles y panelas del sistema presurizado presentaron coloraciones oscuras, tonalidades rojizas, alta turbidez, coeficiente glucósido entre 60 % y 70 % y no solidificaron y las mieles y panelas de los sistemas al vacío presentaron la mayor turbidez, coloraciones claras, tonalidades amarillentas, buena so |
