Abstract:
Abstract Background Mucor hiemalis is a dimorphic fungus that efficiently produces ethanol from different sugars; however, the yield of ethanol production highly depends on the fermentation conditions. Objective The conditions for obtaining a high ethanol production yield were optimized in this study. Materials and methods A response surface methodology was used to optimize pH, temperature, and time of ethanolic fermentation by M. hiemalis. Additionally, wheat flour was enzymatically hydrolyzed and the hydrolysate solution with high glucose concentration was fermented by the fungus. Results Th

Abstract:
Secondary plant metabolites, in particular phenolic compounds, are characterized by great diversity in the plant kingdom and are widely used in the medical and industrial fields. The extraction of these compounds represents a critical step, and the differences in extraction conditions strongly affect the yields and the total concentrations of polyphenols in the extracts. In this way, the objective of the present study was to optimize the extraction parameters of the polyphenols from Lavandula stoechas using the extraction technique assisted by ultrasound.

Abstract:
Mango seed kernel oil (MSKO) contains a high concentration of polyphenol and potential as raw materials of food products oil-based and as a natural antioxidant of functional food. Ethanol was used to the extraction of MSKO by response surface methodology (RSM) as a tool to study the optimum extraction conditions of the oil yield and total polyphenol content (TPC). Three-factor-three-level Central Composite Design (CCD) was employed to optimize extraction time (X1), the ethanol concentration (X2), and the ethanol volume (X3) to obtain a high oil yield and TPC.

Abstract:
Isoliquiritigenin (ILG) of licorice is a potential cancer chemopreventive agent. In this paper, response surface methodology (RSM) integrating with Box-Behnken design (BBD) was firstly employed to optimize the ILG extraction, which based on the single-factor experiments. According to analysis, the effect of extraction time and ethanol concentration on yields was significantly. The optimum values were the ethanol concentration of 73.25%, extraction time of 27.82 min and liquid-solid ratio of 19.10: 1. Under these conditions, the highest yield of ILG from licorice was 0.26 mg/g.

The aim of this study is to determine the levels of yield extract of mangosteen pericarp extracted using Response Surface Methodology (RSM) Central Composite Design (CCD) with various concentrations of ethanol (in the range of 45 to 96 %) and duration of microwave heating (in the range 5.8 to 34.1 o C) or Microwave Assisted Extraction (MAE). The yield extract was calculated as percentage to the weight of origin. The results showed that optimum extraction conditions for yield extract were at ethanol concentration of 70% and heating time of 31.5 minutes which resulted in yield extract of 19.45%.
