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 […]
Synthesis of a new thiophosphorylated compound derived from cashew nut shell liquid and study of its antioxidant activity
This work describes the synthesis and study of the antioxidant activity in mineral oils of new thiophosphorylated compound derived from cashew nut shell liquid (CNSL); a by-product of the process of improvement of cashew nuts. This study was conducted through the thermal analysis observing the Tonset variations and the accelerated oxidation experiments observing the induction […]
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 […]
In vivo Antigenotoxic and Anticlastogenic Effects of Fresh and Processed Cashew (Anacardium occidentale) Apple Juices
Cashew apple juice and cajuina (processed juice) are drinks widely consumed in northeast Brazil. In vitro studies have shown that both juices have antimutagenic activity as well as antioxidant effects. These juices contain vitamins; carotenoids; and phenolic compounds. This in vivo study assessed the antigenotoxic and anticlastogenic effects of both drinks against genotoxicity and mutagenicity […]
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 […]
Effect of roasting on phenolic content and antioxidant activities of whole cashew nuts; kernels; and testa
The effect of roasting on the content of phenolic compounds and antioxidant properties of cashew nuts and testa was studied. Whole cashew nuts; subjected to low-temperature (LT) and high-temperature (HT) treatments; were used to determine the antioxidant activity of products. Antioxidant activities of cashew nut; kernel; and testa phenolics extracted increased as the roasting temperature […]
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 […]
Chromatographic techniques for the determination of alkyl-phenols; tocopherols and other minor polar compounds in raw and roasted cold pressed cashew nut oils
Anacardium occidentale belongs to the family Anacardiaceae and is principally grown in tropical America (Mexico; Peru; Brazil; etc.) and India. Cashew nuts contain low amounts of hydroxy alkyl phenols that come from an oily liquid present in their shell and that is known as cashew-nut shell liquid. This paper reports the alkyl phenols composition of […]
Gasification of cashew nut shells for thermal application in local food processing factory.
Cashew nut shells are high energy content residues from cashew nut processing. It can potentially replace fuelwood for thermal application in a factory. However; direct combustion of cashew nut shells was troublesome due to low efficiency and high smoke emission. Alternative thermal conversion of cashew nut shells should be used instead. In this work; a […]
Cytotoxicity of cashew flavonoids towards malignant cell lines.
The leaves of the Cashew plant (Anacardium occidentale L.) are used by the folk medicine in South America and West Africa. This plant is rich in flavonoids; which are polyphenolic compounds widespread in plants; and that have diverse physiological effects. In a sub-acute toxicity assay it was found that an ethanolic extract of Cashew leaves […]
