A response surface method was used to optimize the microwave-assisted extraction parameters such as extraction time (t) (min), solvent (methanol) concentration (S) (v/v) and microwave power level (MP) for extraction of antioxidants from potato peels. Max. total phenolics content of 3.94 mg g⁻¹ dry weight (dw) was obtained at S of 67.33%, t of 15 min and a MP of 14.67%. For ascorbic acid (1.44 m...

Carvol and carvone are oxidation products from the natural product limonene. They important raw materials for flavours fragrances industry also act as pharmaceutical active ingredients. Orange waste peels possibly represent an attractive source limonene, but studies on valorizing orange peel wastes rare. In this study, we report a new enzymatic cascade system in-situ conversion of limonene into...

India is sitting on a gold mine of well-recorded and traditionally well practiced knowledge of herbal medicine. General phytochemical screening of Citrus sinensis (Orange) belonging Rutaceae family revealed the presence of flavones glycoside. The aim of this study is to identify and characterize the bioactive principle compound (Hesperidin) from the dried peel of C. sinensis fruit. It has wide ...

Peels are major byproducts of the juice processing industry. Citrus peels composed two tissues, namely flavedo (outer layer) and albedo (inner layer). Here, were obtained from peel grapefruit cv. ‘Star ruby’, lemon ‘Akragas’, sweet orange cvs. ‘Tarocco’, ‘Sanguinello’ ‘Moro’. Freeze dried investigated for their functional properties, subjected to enzyme-assisted extraction with pectinase cellul...

Fruits and vegetables include high levels of bioactive compounds with health-promoting effects. Especially, peels, which are one the generaly inedible fractions fruit or vegetable, have higher amount polyphenolic than their pulps seeds, since they accumulate in peels. Purple turnip (Brassica rapa L.) is important members Brassicaceae family due to its nutritional composition. In this context, a...
