The present study is to evaluate and compare the prediction and simulating efficiencies of response surface methodology (RSM) and artificial neural network (ANN) based models on fatty acid methyl esters (FAME) yield achieved from muskmelon oil (MMO) under ultrasonication by two step in situ process. In first in situ process, free fatty acid content of MMO(More)
Ultrasound assisted extraction of pectin from waste pomegranate peel was investigated and optimized using Box-Behnken response surface design coupled with numerical optimization technique. The individual and interactive effect of process variables (solid-liquid ratio, pH, extraction time and temperature) on the pectin yield was studied. The experimental(More)
Supercritical carbon dioxide extraction (SC-CO2) of total anthocyanin and phenolic compounds from jamun fruits was investigated using three factors at three levels Box-Behnken response surface design. Experiments were conducted to evaluate the effects of three independent variables (pressure, temperature and co-solvent flow rate) on the maximum extraction(More)
The objectives of this present study was to investigate and optimize the aqueous extraction conditions such as solid-liquid (SL) ratio (1:5-1:15 g/ml), pH (2-3), extraction time (20-60 min) and extraction temperature (75-95 °C) on maximum extraction of pectin from durian rinds using four factors, three levels Box-Behnken response design. The experimental(More)
In this study, ultrasound-assisted extraction technology was employed to investigate and optimize the crude polysaccharide extraction from Nephelium lappaceum L. fruit peel using three levels, four factors (LS ratio, ultrasonic power, extraction temperature and extraction time) Box-Behnken response surface design. The results showed that highest(More)
The film forming solutions composed of tapioca (cassava) starch (1-3 g), glycerol (0.5-1.0 ml), agar (0.5-1.0 g) and span 80 (0.1-0.5 ml) were prepared according to a three-level, four-factor Box-Behnken response surface experimental design. The films were obtained by casting method and they are homogenous and transparent. The influence of film composition(More)
In this study, an efficient ultrasound-assisted extraction (UAE) of pectin from sisal waste was investigated and optimized. Response surface methodology (RSM) based on a three-level four-factor Box-Behnken response surface design (BBD) was employed to optimize the extraction conditions (ultrasonic power, extraction temperature, extraction time and(More)
Degradation of cassava (tapioca) starch based composite films during indoor soil burial experiments was analyzed using five factors, three levels Box-Behnken response surface design. From the results, it was observed that, increased water sorption promotes the entry of soil microorganism and it utilizes the starch films as a source of energy for their(More)
This present study investigates the extraction characteristics and optimal parameters of the microwave-assisted extraction of pectin from waste mango peel (WMP). Microwave power, pH, time and solid-liquid ratio were selected as the extraction parameters and was studied by using Box-Behnken response surface design. The experimental data was analyzed by least(More)
We present a numerical study of stimulated Brillouin scattering in optical fibers based on a full modal analysis of the acoustic and optical properties. The computation of each acoustic mode supported by the fiber structure allows us a deep and detailed investigation of the characteristics of the Brillouin gain spectrum. We focus our attention on optical(More)
