Vacuum microwave hydrodiffusion and gravity (VMHG), a modified form of solvent free microwave hydrodiffusion and gravity (MHG) technique, was used for extraction of onion by-products. A detailed study concerning about optimisation of different parameters like irradiation power, degree of vacuum and extraction time was performed.
Solvent Free Microwave-Assisted Extraction of Antioxidants
Extracts obtained by solvent-free microwave hydrodiffusion and gravity (MHG) technique and conventional solvent extraction (CSE) method were analysed with HPLC for quantification of flavonoids along with evaluating their phenolic contents by Folin-Ciocalteu method and reducing power by the reduction of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical.

DOCTORAL THESIS UPB
Microwave hydrodiffusion and gravity (MHG) is a new technique for the extraction of bioactive compounds from plants developed by Chemat et al. (Vian et al. 2008). This extraction method combines microwave heating with gravity at atmospheric pressure. Based on a simple principle, this technique does not involve the addition of water or other
