5-Hydroxymethylfurfural (HMF) formation during subcritical water extraction [PDF]

Food Science and Biotechnology, 2018
The aim of this study was to investigate the effect of material type (artichoke leave, lemon peel, flaxseed meal), extraction temperature (50, 100, 120, 140, 160, 180, 200 °C) and static extraction time (5, 15, 30, 45 min) on 5-hydroxymethylfurfural (5-HMF) formation during subcritical water extraction.

Biological soil crusts cause subcritical water repellency in a sand dune ecosystem located along a rainfall gradient in the NW Negev desert, Israel

Journal of Hydrology and Hydromechanics, 2016
The biological soil crusts (BSCs) in the NW Negev cause local water redistribution by increasing surface runoff. The effects of pore clogging and swelling of organic and inorganic crust components were intensively investigated in earlier studies. However,

Green Extraction Technique: Subcritical Water Extraction

World Journal of Environmental Research, 2016
An environmental kindly technique, subcritical water extraction (SWE) are based on using water as extraction solvent at temperatures between 100 °C and 374 °C.  Increasing the temperature at moderate pressure also reduces the surface tension and viscosity of water causes the polarity of subcritical water is comparable to organic solvents. ...

Achievement for Fundamental Study of Subcritical Crack Growth in Rock and Its Ability of Future Development

Journal of MMIJ
To ensure the long-term integrity of a rock mass, understanding the time-dependent fracturing is essential. For this reason, the study of subcritical crack growth in rock has been conducted by various researchers. It has been clarified that the influence
