Potato cubes were dried by different drying methods. After the end of drying process, the experimental data were first fitted to the four well-known drying models. The results indicated that the logarithmic and page models performed better compared with the other models. Also, in this study neural networks were used in order to possibly predict dried potato moisture ratio (y), based on three input variables of drying time, drying temperature and different methods. The results revealed that, logsig function based on 10 neurons in the first hidden layer could perform as the best goodness configuration for predicting the moisture ratio. The comparison of the obtained results of ANNs and classical modeling indicated that, the neural networks have a higher... |

Abstract Agave tequilana Weber azul variety is a valuable source of fructans. In this study, a response surface methodology was employed to optimize the extraction yield of fructans from agave pines. A Box Behnken factorial design was applied to evaluate the effects of several conditions such as extraction temperature, water raw material ratio and extraction time on extraction yield. Under the optimum extraction conditions (extraction temperature of 79.1 °C, water raw material ratio of 5.13 mL/g, and extraction time of 1.48 h) fructans extraction yield was 83.12%. The chromatographic profile of the agave crude extract presented four peaks, out of which fructans were the most preponderant (~87%). The obtained results suggest that the response surface... |
