Antioxidative potential of cashew phenolics in food and biological model systems as affected by roasting
The effect of different roasting conditions on antioxidant capacity of phenolics of cashew nuts and their testa was evaluated using several food and biological model systems. Total phenolic content (TPC) of cashew extracts were determined and accelerated oxidative stability of stripped corn oil in the presence of cashew extracts evaluated. In addition; the antioxidant activity […]
Catechin and epicatechin in testa and their association with bioactive compounds in kernels of cashew nut (Anacardium occidentale L.)
Catechins in testa and bioactive compounds in testa-free and testa-containing kernels of cashew nuts were analyzed. The cashew nut testa contained (+)-catechin and (-)-epicatechin with concentrations of 5.70 and 4.46 g per kg DM; respectively. Testa-containing kernels revealed significantly higher levels of Ã-carotene (218 vs. 89.6 µg/kg DM); lutein (525 vs. 292 µg/kg DM); and […]
Chemical and aroma volatile compositions of date palm (Phoenix dactylifera L.) fruits at three maturation stages
Abstract: The effect of maturity stage on the physicochemical composition and volatile components of date palm fruits (Phoenix dactylifera L.) was investigated at three different stages. Total sugars; pH; proteins and ash increased up to the full-ripe stage of all date types. On the contrary; weight; moisture and total lipids decreased across the same period. […]
Enzymatic Treatment of Peanut Kernels to Reduce Allergen Levels.
Abstract: This study investigated the use of enzymatic treatment to reduce peanut allergens in peanut kernels as affect by processing conditions. Two major peanut allergens; Ara h 1 and Ara h 2; were used as indicators of process effectiveness. Enzymatic treatment effectively reduced Ara h 1 and Ara h 2 in roasted peanut kernels by […]
Pinolenic acid inhibits human breast cancer MDA-MB-231 cell metastasis in vitro
Pinolenic acid (PNA); a naturally-occurring polyunsaturated fatty acid (PUFA); is found mainly in pine seeds. Although many studies have demonstrated beneficial effects of pine seed oil; there are no reports of the biological effects of PNA on cancer metastasis. The objective of this study was to investigate the effect of PNA on human breast cancer […]
Antioxidant properties and chemical composition of technical Cashew Nut Shell Liquid (tCNSL).
The present study analyzed the antioxidant activity of the technical Cashew Nut Shell Liquid (tCNSL) using the 2;2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay and the xanthine oxidase assay; as well as in vivo evaluation by Saccharomyces cerevisiae assay. Also; the chemical composition of tCNSL was determined by gas chromatography-mass spectrometry (GCÂMS); revealing the presence of cardanols (40.26%); […]
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 […]
Hepatoprotective effects of almond oil against carbon tetrachloride induced liver injury in rats
This research aimed at evaluating the protective effects of almond oil against acute hepatic injury induced by carbon tetrachloride in rats. The study results showed that animals received almond oil prior to the administration of CCl4 significantly decreased serum alanine aminotransferase (ALT); aspartate aminotransferase (AST); alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activities; and total […]
Investigation of the roasting conditions with minimal acrylamide generation in tropical almond (Terminalia catappa) nuts by response surface methodology
Considering the importance of acrylamide in heated foods; a study was conducted to find optimum conditions for roasting that will produce minimal acrylamide concentration in tropical almond nuts. The data obtained were analysed using response surface methodology. The results revealed that the most significant (P < 0.05) roasting conditions that affect the acrylamide concentration were […]
Cell proliferation inhibitory and apoptosis inducing properties of anacardic acid and lunasin in human breast cancer MDA-MB-231 cells
The combination of two or more chemopreventive agents is currently being used to inhibitory effects on breast cancer cells. Anacardic acid and lunasin are two plant-derived compounds that have been associated with anti-carcinogenic properties. These compounds show inhibitory effects on cell proliferation and inducing properties of apoptosis in human breast cancer MDA-MB-231 cell line. Both […]
