Screening Natural Antioxidants in Peanut shell Using DPPH-HPLC-DAD-TOF/MS methods.
Peanutshell, a byproduct in oil production, is rich in naturalantioxidants. Here, a rapid and efficient method using DPPH-HPLC-DAD-TOF/MS was used for the first time to screen antioxidants in peanutshell. The method is based on the hypothesis that upon reaction with 1, 1-diphenyl-2-picrylhydrazyl (DPPH), the peak areas of compounds with potential antioxidant activities in the HPLC […]
Carcass performance and meat mineral content in Balouchi lamb fed pistachio by-products
This experiment investigated the effect of pistachio by-products (PB) in the feed of weaned Balouchi lambs on their daily gain, carcass traits and on the levels of Ca, Zn, Fe and Cu of Longissimus dorsi muscle. Twenty eight male lambs were divided into four groups with 7 lambs each and fed separately for 90 days. […]
Preparation of peanut hull-based activated carbon by microwave-induced phosphoric acid activation and its application in Remazol Brilliant Blue R adsorption
Peanut hull; an agricultural solid waste abundantly available in China; was utilized as a precursor for preparation of activated carbon via microwave induced phosphoric acid chemical activation. To optimize the preparation conditions; the effects of the concentration of phosphoric acid; microwave power and radiation time on the adsorption property (expressed in terms of the iodine […]
Development of a Buccal tablets for Curcumin using Anacardium occidentale Gum
The objective of the present investigation was to develop uni-directional, bilayered, buccoadhesive tablets of curcumin using a natural buccoadhesive polymer cashew nut tree gum along with ethyl cellulose as an impermeable backing layer. A batch prepared with 20% polymer concentration, 0.1% penetration enhancer, 40 mg backing layer, compressed at 2 tons/cm2 for 10 sec was […]
Optimizing the removal of fluoride from water using new carbons obtained by modification of nut shell with a calcium solution from egg shell
Carbons loaded with specific chemical moieties were prepared from pecan nut shells employing a natural modifier agent obtained from egg shell; which is rich in calcium; for the selective adsorption of fluoride from water. A L4 orthogonal array of the Taguchi method was used to optimize the synthesis conditions for obtaining these selective carbons. The […]
