Megjegyzések:	In the present study, ultrasound assisted extraction (UAE) of phytochemicals from persimmon fruit peel (PFP) was modeled using an artificial neural network (ANN) and optimized byintegrating with genetic algorithm (GA). The range of process parameters selected for conducting the experiments was ultrasonication power (XU) 150 - 350 W, extraction temperatures (XT) 30 - 70°C, solid to solvent ratio (XS) 1:15 - 1:35 g/ml, and ethanol concentration (XC) 40 - 80%. The range of responses total phenolic content (YP), antioxidant activity (YA), total beta carotenoid (Y?) and total flavonoid content (YF) at various independent variables combinations were found to be 7.72 - 24.62 mg GAE/g d.w., 51.44 - 85.58 %DPPH inhibition, 24.78 - 56.56 ?g/g d.w. and 0.29 - 1.97 mg QE/g d.w. respectively. The modelling utilised an ANN architecture with a configuration of 4-12-4. The training process employed the Levenberg?Marquardt method, whereas the activation function chosen for the layers was the log sigmoid. The optimum condition predicted by the hybrid ANN-GA model for the independent variables, XU, XT, XS and XC was found to be 230.18 W, 50.66 ?C, 28.27 g/ml, and 62.75% respectively. The extraction process was carried out for 25 minutes, with 5-minut intervals, at various temperatures between 30 and 60 ?C, to investigate the kinetic and thermodynamic characteristics of the process, under the optimal conditions of XU, XS and XC. The UAE of phytochemicals from persimmon peel followed pseudo second order kinetic modeland the extraction process was endothermic in nature.

Cím:	Ultrasound assisted phytochemical extraction of red cabbage by using deep eutectic solvent: Modelling using ANFIS and optimization by genetic algorithms / Pusty, Kasturi; Kumar Dash, Kshirod; Raj, Souvik Giri Bhagya; Raj, G.V.S. Bhagya; Tiwari, Ajita; Shaikh, Ayaz Mukarram; Béla, Kovács

Megjegyzések:	The present investigation studied the effect of process parameters on the extraction of phytochemicals from red cabbage by the application of ultrasonication and temperature. The solvent selected for the study was deep eutectic solvent (DES) prepared by choline chloride and citric acid. The ultrasound assisted extraction process was modeled using adaptive neuro-fuzzy inference system (ANFIS) algorithm and integrated with the genetic algorithm for optimization purposes. The independent variables that influenced the responses (total phenolic content, antioxidant activity, total anthocyanin activity, and total flavonoid content) were ultrasonication power, temperature, molar ratio of DES, and water content of DES. Each ANFIS model was formed by the training of three Gaussian-type membership functions (MF) for each input, trained by a hybrid algorithm with 500 epochs and linear type MF for output MF. The ANFIS model predicted each response close to the experimental data which is evident by the statistical parameters (and RMSE <1.165). The integrated hybrid ANFIS-GA algorithm predicted the optimized condition for the process parameters of ultrasound assisted extraction of phytochemicals from red cabbage was found to be 252.114?W for ultrasonication power, 52.715??C of temperature, 2.0677:1 of molar ratio of DES and 25.947?% of water content in DES solvent with maximum extraction content of responses, with fitness value 3.352. The relative deviation between the experimental and ANFIS predicted values for total phenolic content, antioxidant activity, total anthocyanin activity, and total flavonoid content was found to be 1.849?%, 3.495?%, 2.801?%, and 4.661?% respectively.
