Optimization and Kinetic Studies of Ultrasound-Assisted Extraction on Polyphenols from Satsuma Mandarin (Citrus Unshiu Marc.) Leaves
The present article includes the Ultrasound-Assisted Extraction (UAE) of Citrus unsiu Marc. leaves rich in polyphenols. The best possible combinations of solvent, pH of the media, solvent/solid ratio, extraction time, extraction temperature and particle size were obtained for the maximum extraction of Total Phenolic Compounds (TPC) and Total Flavonoid Compounds (TFC) by us...
متن کاملBreakage of Cellular Tissue by Pulsed Electric Field: Extraction of Polyphenols from Fresh Tea Leaves
Pulsed electric field (PEF) is commonly understood as a fast, non-thermal, and highly effective method for extraction of intracellular compounds. This treatment involves discharge of high voltage electric pulses of a few microseconds into the food product which is placed or passed between two electrodes (Angersbach et al., 2000). Results of experimental investigation of the electric breakage of...
متن کاملSolvent-Free Microwave-Assisted Extraction of Polyphenols from Olive Tree Leaves: Antioxidant and Antimicrobial Properties.
Response surface methodology (RSM) and artificial neural networks (ANN) were evaluated and compared in order to decide which method was the most appropriate to predict and optimize total phenolic content (TPC) and oleuropein yields in olive tree leaf (Oleaeuropaea) extracts, obtained after solvent-free microwave-assisted extraction (SFMAE). The SFMAE processing conditions were: microwave irradi...
متن کاملDelivery of tea polyphenols to the oral cavity by green tea leaves and black tea extract.
Catechins and theaflavins, polyphenolic compounds derived from tea (Camellia sinensis, fam. Theaceae), have been reported to have a wide range of biological activities including prevention of tooth decay and oral cancer. The present study was undertaken to determine the usefulness of green tea leaves and black tea extract for the delivery of catechins and theaflavins to the oral cavity. After h...
متن کاملExtraction and Microencapsulation of Polyphenols from Orthosiphon Stamineus Leaves
This paper presents an extraction and microencapsulation study of polyphenols obtained from Orthosiphon stamineus leaves. Extraction using aqueous solvent enabled a simultaneous extraction of both hydrophilic and lipophilic phenolic compounds. Higher solid concentration leads to higher solution viscosity, bigger particle size, lower moisture content and a less dented surface, which may improve ...
