Comparative study of two extraction techniques to obtain representative aroma extracts for being analysed by gas chromatography-olfactometry: Application to roasted pistachio aroma.

This research paper presents a comparative study of two different extraction and concentration techniques to obtain representative pistachio aroma extracts: the traditional direct solvent extraction (DSE) followed by high-vacuum transfer (HVT) and the headspace solid-phase microextraction (HS-SPME). The results showed that; although both techniques provide accurate information about the aromatic composition that will be perceived […]

Report: prunes and liver function: a clinical trial.

Prunes are used by folks as a remedy of various diseases including hepatitis. A clinical trial was designed to see the effects of prunes (Prunus domestica) on liver function. 166 healthy volunteers were divided into three groups randomly. Either three (about 11.43g) or six (23g approx.) prunes were soaked in a glass of water (250ml) […]

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 (71.01–93.46% dry matter); with high proportions of insoluble dietary fibre. Freeze dried DFC had the highest values of swelling; water holding and oil holding […]

Modelling spatial and temporal variability in a zero-inflated variable: The case of stone pine (Pinus pinea L.) cone production

Modelling masting habit; i.e. the spatial synchronized annual variability in fruit production; is a huge task due to two main circumstances: (1) the identification of main ecological factors controlling fruiting processes; and (2) the common departure of fruit data series from the main basic statistical assumptions of normality and independence. Stone pine (Pinus pinea L.) […]

Reduction in the Incidence of Type 2-Diabetes with the Mediterranean Diet: Results of the PREDIMED-Reus Nutrition Intervention Randomized Trial

Objective: To test the effects of two Mediterranean-diet interventions versus a low-fat diet on incidence of diabetes. Research Design and Methods: Three-arm randomized trial in 418 nondiabetic subjects aged 55-80 years recruited in one center (PREDIMED-Reus; North-Eastern Spain) of the PREDIMED study; a large nutrition-intervention trial for primary cardiovascular prevention in persons at high cardiovascular […]

Prenatal Omega-3 Fatty Acids: Review and Recommendations

The influence of dietary omega-3 fatty acids on health outcomes is widely recognized. The adequate intake of omega-3 fatty acids docasahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in particular can increase gestation length and improve infant cognitive and visual performance. Adequate levels of omega-3 fatty acids have also been shown to reduce the incidence of […]

Evaluation of energy and dietary intake estimates from a food frequency questionnaire using independent energy expenditure measurement and weighed food records

BACKGROUND: We have developed a food frequency questionnaire (FFQ) for the assessment of habitual diet; with special focus on the intake of fruit; vegetables and other antioxidant-rich food and beverages. The aim of the present study was to evaluate the relative validity of the intakes of energy; food and nutrients from the FFQ. METHODS: Energy […]
