Pomegranate peel is a rich source of phenolic compounds (such as punicalagin and hydroxybenzoic acids). However, the content of such bioactive compounds in the peel extract can be affected by extraction type and condition. It was hypothesized that the optimization of a pulsed ultrasound-assisted extraction (PUAE) technique could result in the pomegranate peel extract with higher yield and antio...

Proteins isolated from sweet potatoes (Ipomoea batatas) have been shown to possess antidiabetic, antioxidant, and antiproliferative properties. The objective of this study was to chemically optimize a process for extracting proteins from sweet potato peel. The extraction procedure involved mixing peel with saline solvent to dissolve proteins and then precipitating with CaCl2. Quadratic and segm...

BACKGROUND The use of pomegranate peel is highly associated with its rich phenolic concentration. Series of drying methods are recommended since bioactive compounds are highly sensitive to thermal degradation. The study was conducted to evaluate the effects of drying on the bioactive compounds, antioxidant as well as antibacterial and antityrosinase activities of pomegranate peel. METHODS Dri...

BACKGROUND Commercial available skin prick test with fruits can be negative in sensitized or allergic patients due to a reduction in biological activity during the manufacturing process. Prick-prick tests with fresh foods are often preferred, but they are a non-standardized procedure. The usefulness of freeze-dried extracts of Canary Islands tomatoes, comparing the wheal sizes induced by prick ...

Valencia orange (Citrus sinensis) peel was employed in this work as raw material for the production of citric acid (CA) by solid-state fermentation (SSF) of Aspergillus niger CECT-2090 (ATCC 9142, NRRL 599) in Erlenmeyer flasks. To investigate the effects of the main operating variables, the inoculum concentration was varied in the range 0.5·10(3) to 0.7·10(8) spores/g dry orange peel, the bed ...

abstract in this study, the physicochemical quality and antioxidant activities of fruits peel from 6 citrus varieties which commonly consumed in the north of iran were determined. some parameters were measurement such fruit size, peel thickness, residue percentage, peel color indices, total phenolics, total flavonoid, total anthocyanins, total carotenoids, total chlorophyll, ascorbic acid conte...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

BACKGROUND The medical application of pomegranate fruits and its peel is attracted human beings. The aim of the present study was to evaluate the in vitro α-Glucosidase inhibition, antimicrobial, antioxidant property and in vivo anti-hyperglycemic activity of Punica granatum (pomegranate) fruit peel extract using Caenorhabditis elegans. METHODS Various invitro antioxidant activity of fruit pe...

A simple model for the peeling process of pressure-sensitive adhesive tape is presented. The model consists of linear springs and dashpots and can be solved analytically. Based on the modeling, the curved profile of the peeling tape is spontaneously determined in terms of viscoelastic properties of adhesives. Using this model, two experimental results are discussed: critical peel rates in the p...
