A study of the extraction of oak wood compounds with subcritical water-ethanol mixtures as extractant, with an ethanol content between 0-60%, is reported. Identification and characterisation of the extracted compounds have been made by spectrophotometry and gas chromatography with either flame ionisation or mass detectors. Extraction was performed statically manner by use of a single cycle or r...

In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.80 min, and particle size of 0.26 mm. No significant differences were found between the experimental and p...

The aim of the present study was determine optimum processing conditions and nanoemulsion formulation for preparation gingerol shogaol from ginger extract-based subcritical water. For this purpose, nanoemulsions were prepared with rotor-stator homogenizer varied surfactant cosurfactant concentrations (24%, 26% 28% v/v), stirring speed (22,000 rpm, 24,000 rpm). time is adjusted to 30 minutes. de...
