From ‘green’ technologies to ‘red’ antioxidant compounds extraction of purple corn: a combined ultrasound–ultrafiltration–purification approach

Abstract

From the results obtained in the present study, it can be concluded that the proposed extraction-separation-filtration-purification method applied under the optimal conditions could be scaled-up to recover anthocyanins and zein simultaneously. Moreover, under the selected conditions, no significant degradation of anthocyanins was observed. © 2018 Society of Chemical Industry.

Enhancing the Potentiality of Trichoderma harzianum against Pythium Pathogen of Beans Using Chamomile (Matricaria chamomilla, L.) Flower Extract

“…The extraction strategies for phytonutrients of chamomile could be subjected to several techniques, of which several employ the use of environmentally safe and nontoxic solvents [30]. In general, the extraction of various phytochemicals, specifically polyphenolic compounds is effectively done by solvents such as methanol, ethanol, glycerol and water [31].…”

Effect of Different Green Extraction Methods and Solvents on Bioactive Components of Chamomile (Matricaria chamomilla L.) Flowers

“…In the production of extracts from natural sources various isolation techniques are combined while more and more attention is gained to the techniques focused to the principles of "green chemistry", which among other things assumes using environmentally safe and nontoxic solvents [8][9][10][11]. For the extraction of various phytochemicals, specifically polyphenolic compounds the efficient solvents are usually ethanol, methanol, glycerol and their water solutions [12][13][14][15].…”

Review of ultrasound combinations with hybrid and innovative techniques for extraction and processing of food and natural products

“…This technique has been increasingly used in the alimentary field including processing (crystallization, drying, filtration, cutting, etc. ), preservation (inactivation of microorganisms and enzymes) and extraction processes [10] , [11] , [12] . These applications have already been listed in many reviews and scientific articles.…”
