Biodiesel from Siberian apricot (Prunus sibirica L.) seed kernel oil
In this paper, Siberian apricot (Prunus sibirica L.) seed kernel oil was investigated for the first time as a promising non-conventional feedstock for preparation of biodiesel. Siberian apricot seed kernel has high oil content (50.18±3.92%), and the oil has low acid value (0.46mg g-1) and low water content (0.17%). The fatty acid composition of the […]
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 […]
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 […]
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 […]
Defatted cashew nut shell starch as renewable polymeric material: Isolation and characterization
Starch attracts public attention as a replacement of fossil fuel in polymer industries because it is renewable; biodegradable and nontoxic. In this study; the isolation of starch from defatted cashew nut shell (CNS) using wet milling was reported. A product that contains 85.01 wt.% starch was recovered from the defatted CNS. Various analyses were performed […]
Use of date (Phoenix dactylifera L.) blanching water for reconstituting milk powder: yogurt manufacture
The processing of dates yields high volumes of blanching water. The use of such blanching water for reconstituting skim milk powder to produce low fat yogurt was studied. Physicochemical properties and antioxidant activity of two date cultivars (Medjoul and Confitera) blanching water were determined. Quality characteristics of yogurts (control; Medjoul and Confitera) were evaluated during […]
Antioxidant Potential of Chestnut (Castanea sativa L.) and Almond (Prunus dulcis L.) By-products
The antioxidant properties of almond green husks (Cvs. Duro Italiano; Ferraduel; Ferranhês; Ferrastar and Orelha de Mula); chestnut skins and chestnut leaves (Cvs. Aveleira; Boa Ventura; Judia and Longal) were evaluated through several chemical and biochemical assays in order to provide a novel strategy to stimulate the application of waste products as new suppliers of […]
Effect of drying methods on physico-chemical and antioxidant properties of date fibre concentrates
Effects of different drying methods (freeze-; oven- and sun-drying) on physico-chemical properties of date fibre concentrates (DFC) from three potential Tunisian cultivars were investigated. DFC had high contents of dietary fibre (71.01Â93.46% dry matter); with high proportions of insoluble dietary fibre. Freeze dried DFC had the highest values of swelling; water holding and oil holding […]
Walnut (Juglans regia L.): genetic resources; chemistry; by-products
Walnut (Juglans regia L.) is the most widespread tree nut in the world. There is a great diversity of genotypes differing in forestry; productivity; physical and chemical nut traits. Some of them have been evaluated as promising and may serve as germplasm sources for breeding. The nutritional importance of the nut is related to the […]
Antiradical activity of extracts of almond and its by-products
Antioxidant activities of ethanolic extracts of whole almond seed, brown skin, and green shell cover were evaluated using different free radical trapping assays. Trolox equivalent antioxidant capacity assay revealed that the total antioxidant capacities of brown skin and green shell cover extracts were 13 and 10 times greater than that of the whole seed extract […]
