Physicochemical changes in Mazafati date fruits incubated in hot acetic acid for accelerated ripening to prevent diseases and decay
A method was developed and optimized for the accelerated ripening of date fruits of cultivar ÂMazafati to prevent diseases and decay. The date fruits were incubated in hot acetic acid solution 0.5% at 40 + 1 °C for 72 h. During the process some physicochemical changes in the fruits were studied and were found to […]
Cultural and historical aspects of Mediterranean nuts with emphasis on their attributed healthy and nutritional properties
BACKGROUND AND AIMS: Nuts have been part of the human diet since prehistoric times. The aim of the present article is to describe the most important historical and cultural aspects of nut consumption throughout history. DATA SYNTHESIS: We discuss the following historical aspects of nuts originating in the Mediterranean: prehistory; the Egyptian civilization; their spread […]
Characteristics of some almond kernel and oils.
The proximate properties; the fatty acid and mineral contents of different almond kernel varieties were determined. The crude protein contents of kernels ranged between 12.7% (guara) and 16.3% (cristomorto). The oil yields from these kernels were established between 48.8% (cristomorto) and 55.7% (ferragnes). The acidity value of oils were found between 1.389 and 3.559%. In […]
Effect of increasing climatic water deficit on some leaf and stomatal parameters of wild and cultivated almonds under Mediterranean conditions.
The prevailing environmental conditions; temperature in particular; drive seasonal changes both in leaf development and stomatal characteristics. In order to ascertain the effect of increases in climatic water deficit on some leaf and stomatal parameters under field conditions; a study was carried out on two sets of leaves (spring and summer) on a large sample […]
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 […]
Pecans Acutely Increase Plasma Postprandial Antioxidant Capacity and Catechins and Decrease LDL Oxidation in Humans.
Bioactive constituents of pecan nuts such as -tocopherol and flavan-3-ol monomers show antioxidant properties in vitro; but bioavailability in humans is not known. We examined postprandial changes in plasma oxygen radical absorbance capacity (ORAC) and in concentrations of tocopherols; catechins; oxidized LDL; and malondialdehyde (MDA) in response to pecan test meals. Sixteen healthy men and […]
The effect of genotype and roasting on the fatty acid composition of peanuts.
The impact of two factors; genotype (G) and treatment (raw or roasted peanut) (T); on the chemical composition of peanuts was studied using a chemometric method and Tukey's test. The peanut genotypes evaluated were cultivar cavalo vermelho (CCV); cultivar cavalo rosa (CCR) and cultivar tatu (CTA); in both raw and roasted states. The total lipid […]
Nut-induced Dysgeusia: An Emerging Problem!
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 […]
Walnut (Juglans regia L.): genetic resources; chemistry; by-products
Walnut (Juglans regia L.) is the most widespread tree nut in the world. There is a great diversity of genotypes differing in forestry; productivity; physical and chemical nut traits. Some of them have been evaluated as promising and may serve as germplasm sources for breeding. The nutritional importance of the nut is related to the […]
