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Current prune composition data are outdated and require a comprehensive and comparative re-analysis.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 […]
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 […]
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 […]
Investigation of serotonin, free and protein-bound tryptophan in Turkish hazelnut varieties and effect of roasting on serotonin content.
Hazelnuts and their skins are important sources of health-promoting compounds. In this study, serotonin, a neuroactive compound, and its precursor tryptophan in 14 hazelnuts, almost all hazelnut varieties in Turkey, in two consecutive harvest years were investigated. Serotonin content of hazelnut skins and the effect of roasting on the serotonin content of hazelnuts were also revealed for the first […]
Raisin processing: physicochemical, nutritional and microbiological quality characteristics as affected by drying process.
Processing and conservation of grapes by suitable techniques has been a major challenging issue for a long time. Optimization of drying and pretreatment operations of this fruit have been extensively studied. However, in order to achieve the production of high-quality raisins and reach consumers’ acceptance, special attention for quality attributes should be taken into account. […]
Review on fresh and dried figs: Chemical analysis and occurrence of phytochemical compounds, antioxidant capacity and health effects.
Fig fruit (Ficus carica L.) is one of the most important agricultural products of the tropic and subtropics areas. In the Middle East and the Mediterranean region, the fig is included in diet since the ancient years and it is considered as the symbol of longevity. This review presents the main phytochemical compounds found in fresh and dried figs […]
Extraction Technology Can Impose Influences on Peanut Oil Functional Quality: A Study to Investigate the Lipid Metabolism by Sprague–Dawley Rat Model.
In this study, peanut oil was prepared by cold pressing (temperature under 60 °C), hot pressing (temperature above 105 °C), and enzyme-assisted aqueous extraction technology. Influences of an extraction technology on the oil fatty acid composition and the content of minor bioactive compounds, including tocopherols, polyphenols, and squalene, were investigated in detail. High-fat-diet Sprague-Dawley (SD) rat model […]
Influence of particle size and intestinal conditions on in vitro lipid and protein digestibility of walnuts and peanuts.
A static in vitro model was used to assess walnuts and peanuts macronutrient digestion of with two different particle size. Nuts were digested under different intestinal conditions of pH (6 or 7), bile concentration (1-10 mM) and pancreatic concentration (1000 to 4000 LU/g fat) the matrix degradation index (MDI), proteolysis and lipolysis were analyzed. Results showed that nuts particle […]
Biomarkers of food intake for nuts and vegetable oils: an extensive literature search.
Nuts and vegetable oils are important sources of fat and of a wide variety of micronutrients and phytochemicals. Following their intake, several of their constituents, as well as their derived metabolites, are found in blood circulation and in urine. As a consequence, these could be used to assess the compliance to a dietary intervention or […]
