Inductively coupled plasma-mass spectrometry (ICP-MS) and -optical emission spectroscopy (ICP–OES) for determination of essential minerals in closed acid digestates of peanuts (Arachis hypogaea L.).
Validated methods to measure the essential mineral composition of food matrices are needed to satisfy the analytical requirements of product development, quality control, and food regulatory authorities. We investigated the use of inductively coupled plasma–optical emission spectroscopy (ICP–OES) and -mass spectrometry (ICP-MS), with and without the use of a dynamic reaction cell (DRC), to analyse […]
Evaluation of the total phenolics and quercetin content of foliage in mycorrhizal grape (Vitis vinifera L.) varieties and effect of postharvest drying on quercetin yield
Chemical and Structural Characterisation of Almond Oil Bodies and Bovine Milk Fat Globules
Lipids in almonds are present as oil bodies in the nut. These oil bodies are surrounded by a membrane of proteins and phospholipids and are a delivery vehicle of energy in the form of triglycerides; similarly to the more studied bovine milk fat globule membrane. Chemical; physical and microscopic analyses revealed major differences in the […]
Changes in the phenolic and lipophilic composition; in the enzyme inhibition and antiproliferative activity of Ficus carica L. cultivar Dottato fruits during maturation
Fruits of Ficus carica cultivar Dottato from Italy were examined to assess how the stage of ripeness influences their chemical composition; antioxidant activity; pancreatic lipase inhibition and antiproliferative properties on C32 melanoma cells. First harvested fruits (June) showed a major content in furanocoumarins and pyranocoumarins whereas the fruits collected in September showed the highest polyphenolic […]
Profiling of bioactive compounds in cultivars of Runner and Valencia peanut market-types using liquid chromatography/APCI mass spectrometry
Peanuts are classified into four market-types (Runners; Spanish; Virginia and Valencia) Studies on their phytochemical composition have focused mainly on market-types other than Valencia. The objectives of this study are to evaluate the phytochemical composition of cultivars of Valencia and Runner market-types. Extracts of twenty-five peanut cultivars of Runner and Valencia market-types were analyzed using […]
Tree nut phytochemicals: composition; antioxidant capacity; bioactivity; impact factors. A systematic review of almonds; Brazils; cashews; hazelnuts; macadamias; pecans; pine nuts; pistachios and walnuts
Tree nuts contain an array of phytochemicals including carotenoids; phenolic acids; phytosterols and polyphenolic compounds such as flavonoids; proanthocyanidins (PAC) and stilbenes; all of which are included in nutrient databases; as well as phytates; sphingolipids; alkylphenols and lignans; which are not. The phytochemical content of tree nuts can vary considerably by nut type; genotype; pre- […]
Postprandial effects of almond consumption on human osteoclast precursors-an ex vivo study
Consumption of almonds has been associated with increased bone mineral density; but the direct effects of almonds on bone cells are not known. We determined whether serum obtained following the consumption of a meal containing 60 g of almonds affects human osteoclast formation; function; and gene expression in vitro. Human osteoclast precursors were cultured in […]
A review of composition studies of cultivated almonds: Macronutrients and micronutrients
Prunus dulcis; the cultivated sweet almond; has long been recognized as a source of nutrients in many traditional diets; and is increasingly promoted as a healthy snack and ingredient. This paper reviews the global research over the past 50 years that has contributed to knowledge on the composition and characterization of almond macronutrients and micronutrients; […]
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 […]
Nutritional quality of 18 date fruit varieties
The aim of the present study was to analyze and compare the chemical and physical properties of 18 varieties of the date fruits from date palm (Phoenix dactylifera); which are regarded as popular fruit commodities among the populace of the Middle Eastern peninsula. Dietary fiber; proximate analysis; micronutrients (micro-elements and macro-elements) and physical properties (weight; […]
