Thermal stability of liquid antioxidative extracts from pomegranate peel

Journal of the Science of Food and Agriculture, 2013
AbstractBACKGROUNDLiquid extracts from pomegranate peel have the potential for use as natural antioxidant products. This study investigates the quality changes of liquid extracts before and after thermal treatment during sterilization and storage. Liquid pomegranate peel extracts were prepared, sterilized under ultra‐high temperature (UHT) at 121 °C ...

Evaluation of antioxidant properties of pomegranate peel extract in comparison with pomegranate pulp extract

Food Chemistry, 2006
Pomegranate is an important source of bioactive compounds and has been used for folk medicine for many centuries. Pomegranate juice has been demonstrated to be high in antioxidant activity and is effective in the prevention of atherosclerosis. In a previous study, we found that pomegranate peel had the highest antioxidant activity among the peel, pulp ...

Pressurised water extraction of polyphenols from pomegranate peels

Food Chemistry, 2010
Abstract Pomegranate peels are one of the most valuable by-products of the food industry in terms of polyphenols which are conventionally extracted from plant materials by organic solvents, especially with methanol. Pressurised water extraction was investigated for the extraction of polyphenols from pomegranate peels.

Antioxidant and antimutagenic activities of pomegranate peel extracts

Food Chemistry, 2003
Abstract Dried pomegranate peels were powdered and extracted in a Soxhlet extractor with ethyl acetate (EtOAc), acetone, methanol and water for 4 h each. The dried extracts were used to determine their antioxidant capacity by the formation of phosphomolybdenum complex and antimutagenicity against the mutagenicity of sodium azide by the Ames test. All

Antimicrobial activity of pomegranate peel extracts as affected by cultivar

Journal of the Science of Food and Agriculture, 2016
AbstractBACKGROUNDSome studies have reported that different parts of the pomegranate fruit, especially the peel, may act as potential antimicrobial agents and thus might be proposed as a safe natural alternative to synthetic antimicrobial agents. The high tannin content, especially punicalagin, found in pomegranate extracts, has been reported as the ...

Green Synthesis of Silver Nanoparticles Using Pomegranate Peel Extract

Advanced Materials Research, 2015
Silver nanoparticle (AgNP) is extensively used in the consumer products and in the medical applications due to its antibacterial property. In this study, AgNPs were synthesized by a simple green chemistry procedure using three difference pH values of pomegranate peel extract as reducing and stabilizing agent and silver nitrate (AgNO3) as a precursor ...
