Marker-assisted backcrossing to improve seed oleic acid content in four elite and popular peanut (Arachis hypogaea L.) cultivars with high oil content.
High oleic acid composition is an important determinant of seed quality in peanut (Arachis hypogaea) in regard to its nutritional benefits for human health and prolonged shelf-life for peanut products. To improve the oleic acid content of popular peanut cultivars in China, four peanut cultivars of different market types were hybridized with high-oleic-acid donors and backcrossed […]
Determination of the protein quality of almonds (Prunus dulcis L.) as assessed by in vitro and in vivo methodologies.
Almonds (Prunus dulcis), such as all nuts, are positioned within the protein foods grouping within the current U.S. Dietary Guidelines. The ability to make claims related to the protein content of almonds, within the United States, requires substantiation via the use of the Protein Digestibility‐Corrected Amino Acid Score (PDCAAS). The present study was designed to […]
Water‐soluble vitamin content of sun‐dried Corinthian raisins (Vitis vinifera L., var. Apyrena).
BACKGROUND: Corinthian raisins are dried vine products, representing approximately 3% of the world dried vine fruit production. The majority of Corinthian raisin production is of Greek origin. Studies on the B-group vitamin content of Corinthian raisins produced in Greece as well as on the effect of region and cultivation altitude on the B-group vitamin content […]
Effect of storage temperature on lipid oxidation and changes in nutrient contents in peanuts.
Peanut, an important oil crop worldwide, is highly susceptible to oxidative damage during storage due to its high level of fats and unsaturated fatty acids which will affects its nutritional value and agricultural importance. Therefore, it is significantly important to research the physicochemical properties changes of peanuts during storage. Peanuts belong to two varieties were stored at various temperatures […]
Enzymolysis of walnut (Juglans regia L.) meal protein: Ultrasonication‐assisted alkaline pretreatment impact on kinetics and thermodynamics.
To improve the utility of walnut meal protein, influences of ultrasonication on the kinetic and thermodynamic constraints of enzyme (trypsin) hydrolysis were assessed using a multi-frequency counter current S-type ultrasound machine. Results revealed that both the ultrasonication treatment and control hydrolysis obeyed the first-order kinetics within the study constraints. After 90 min hydrolysis time, the uppermost […]
Nutrition Quality Parameters of Almonds as Affected by Deficit Irrigation Strategies.
The influence of full irrigation, double-regulated (RDI) and sustained deficit irrigation (SDI) treatments on almond quality was assessed by analyzing different parameters: sugars, organic acids, antioxidant activity, total phenolic content (TPC), and volatile compounds. Almond quality studies for plants submitted to water stress are scarce, and it is essential to understand the biochemical responses of […]
Selected nutrients and anti‐nutrients in peanut cultivars harvested in Brazil.
BACKGROUND: There are more than 30 peanut cultivars registered in Brazil. However, there is no published data about the content of nutrients and anti-nutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid compositions and contents of selected minerals […]
Nutrient, fibre, sorbitol and chlorogenic acid content of prunes (Prunus domestica): an updated analysis and comparison of different countries of origin and database values.
Current prune composition data are outdated and require a comprehensive and comparative re-analysis. This novel study aimed to: (i) analyse and compare prune composition from major countries of origin; and (ii) provide a comprehensive compositional analysis of prunes of USA origin and compare this with UK and USA database data. Prune samples were analysed for […]

BACKGROUND: Corinthian raisins are dried vine products, representing approximately 3% of the world dried vine fruit production. The majority of Corinthian raisin production is of Greek origin. Studies on the B-group vitamin content of Corinthian raisins produced in Greece as well as on the effect of region and cultivation altitude on the B-group vitamin content […]
Evaluation and exploitation of bioactive compounds of walnut, Juglans regia.
In the last few years, a great importance has been given to natural materials (such as walnuts, peanuts, chestnuts) due to their medicinal and pharmaceutical uses induced by the presence of natural agents, including polyphenols. Juglans regia is a traditional plant that has been used since ancient times in traditional medicine for the treatment of […]
