Ginger is one of the commonly used spices that has been exhibited to have pharmaceutical activities. These therapeutic properties are mainly attribute to gingerols and shogaols. To extract these bioactive compounds, subcritical water extraction (SWE) was employed as a green method. The influence of adding co-solvents, temperature, retention time and particle size on extraction yield were invest...

Pressurized hot water extraction (PHWE) is a very useful technique for recovering bioactive molecules from natural materials using subcritical compressed liquid water in the temperature range of 50–150 ◦C. A novel process has been developed for making a natural sweetener from licorice (Glycyrrhiza glabra) roots involving selective chemical reaction and easy separation, for recovering mono-ammon...

The potential effects of three modern extraction technologies (cold-pressing, microwaves and subcritical fluids) on the recovery of oil from Chaenomelessinensis (Thouin) Koehne seeds have been evaluated and compared to those of conventional chemical extraction methods (Soxhlet extraction). This oil contains unsaturated fatty acids and polyphenols. Subcritical fluid extraction (SbFE) provided th...

Obesity-induced inflammation is crucial in the pathogenesis of insulin resistance and type 2 diabetes. In this study, we investigated effects Gracilaria chorda (GC) on lipid accumulation obesity-induced inflammatory changes or glucose homeostasis cell models (3T3-L1 adipocytes RAW 264.7 macrophages). Samples GC were extracted using solvents (water, methanol, ethanol) subcritical water (SW) at d...

A subcritical water degradation and extraction method was developed to remediate environmental soils contaminated by highly recalcitrant organochlorine pollutants. Hydrogen peroxide used effectively decompose pollutants under conditions. As a optimization study, the static wet oxidation of chlorophenols first performed in with without added hydrogen peroxide. Complete achieved using an oxidant,...

Abstract The extraction of bioactive compounds from malted quinoa flour using different water/ethanol mixtures under subcritical conditions was performed, and two mathematical models to describe the kinetics were compared. variables evaluated temperature, solvent mass flow rate composition, best selected a screening design. extract with highest antioxidant activity 95% inhibition DPPH, 2084 mg ...
