Oxidative Stability of Tree Nut Oils

The oxidative stability of selected tree nut oils was examined. The oils of almond; Brazil nut; hazelnut; pecan; pine nut; pistachio; and walnut were extracted using two solvent extraction systems; namely; hexane and chloroform/methanol. The chloroform/methanol system afforded a higher oil yield for each tree nut type examined (pine nut had the highest oil content; […]

Fatty acid profile; tocopherol; squalene and phytosterol content of brazil; pecan; pine; pistachio and cashew nuts

Nuts contain bioactive constituents that elicit cardio-protective effects including phytosterols; tocopherols and squalene. The objective of the present study was to determine the total oil content; peroxide value; fatty acid composition and levels of tocopherols; squalene and phytosterols in oil extracted from freshly ground brazil; pecan; pine; pistachio and cashew nuts. The total oil content […]

Combined use of total metal content and size fractionation of metal biomolecules to determine the provenance of pine nuts (Pinus pinea)

Four essential elements (Mn; Ni; Zn; and Cu) and their molecular-size distribution patterns have been determined; for twenty four samples of pine nuts from eight areas in Spain and Portugal (Huelva; Cádiz; Badajoz; Cataluña; Castilla; Madrid; Faro; and Coimbra); by size-exclusion liquid chromatography (SEC) coupled on-line to UV and inductively coupled plasma mass spectrometric (ICP-MS) […]
