The Type of Dietary Fat in an Isocaloric Breakfast Meal Does Not Modify Postprandial Metabolism in Overweight/Obese Pregnant Women.
Abstract: Almonds provide a satiating, healthy source of fat and fiber. The postprandial metabolic and satiety response to 2 ounces of nuts or dairy was assessed in 18 overweight/obese women during late pregnancy. Serum glucose, triglycerides, insulin, c-peptide, leptin, ghrelin, and lipoprotein particles were measured prior to and during a 5-h postprandial period following the […]
Use of a modified QuEChERS method for the determination of mycotoxin residues in edible nuts by nano flow liquid chromatography high resolution mass spectrometry.
A nanoflow liquid chromatography high resolution mass spectrometry method for the quantification of mycotoxins in nuts has been developed. Two strategies based on QuEChERS methodology were evaluated. Thus, EMR-lipid was compared with a conventional mixture of PSA and C18 dispersive solid phase extraction sorbents which have been commonly used in this type of matrices as […]
HR‐LC‐ESI‐Orbitrap‐MS based metabolite profiling of Prunus dulcis Mill. (Italian cultivars Toritto and Avola) husks and evaluation of antioxidant activity.
INTRODUCTION: Prunus dulcis Mill. is a plant cultivated for the production of its edible seeds, known as sweet almonds. In the last decades almond demand has highly increased due to their wide use in the industrial manufacturing of almond-based foods; this has led to a huge production of waste materials, mainly corresponding to shells and […]
A review of the sensory and chemical characteristics of almond flavor.
Understanding almond flavor, both in terms of sensory aspects and chemistry, is essential for processors to maintain almond quality and to correctly identify acceptable or unacceptable product. This overview of the sensory and chemical characteristics of almond flavor discusses raw and heat-processed almonds, the volatile compounds generated upon heating, the aroma qualities associated with various volatiles, […]
Effect of roasting conditions on color and volatile profile including HMF level in sweet almonds (Prunus dulcis).
Microwave, oven, and oil roasting of almonds were used to promote almond flavor and color formation. Raw pasteurized almonds were roasted in a microwave for 1 to 3 min, in an oven at 177 °C for 5, 10, 15, and 20 min; and at 135 and 163 °C for 20 min, and in oil at […]
Optimization of a headspace SPME GC–MS methodology for the analysis of processed almond beverages.
Optimization of a headspace–solid phase microextraction (HS-SPME) technique for analyzing the volatile profile of almond beverages was performed. An ultra-high temperature (UHT)-treated almond beverage prepared at the pilot plant was used as a model for this kind of vegetable beverage. For the analysis a 2-mL almond beverage, aliquot was used in the presence of salt […]
Survival and Thermal Resistance of Salmonella Enteritidis PT 30 on Almonds after Long-Term Storage.
Salmonella survival and thermal resistance on the surface of almond kernels were evaluated after periods of storage. Almond kernels were inoculated with Salmonella enteritidis PT 30 and equilibrated to 0.45 water activity. Samples were separated into two groups (I and II) and stored in sealed metal cans at room temperature. Group I samples (stored 7, […]
The Effects of Nut Consumption on Vascular Function.
Vascular stiffness can be measured using numerous techniques including assessments of central haemodynamics, aortic arterial stiffness, and indices of aortic wave reflection and endothelial dilatation. Impaired vascular function is associated with increased risk of cardiovascular disease (CVD). Epidemiological studies indicate that regular nut consumption reduces CVD risk, with one of the proposed mechanisms being via […]
Comparison of amygdalin and benzaldehyde levels in California almond (Prunus dulcis) varietals.
Almonds (Prunus dulcis), are characterized into three flavor phenotypes: bitter, semi-bitter and sweet. Amygdalin is a cyanogenic diglucoside responsible for bitterness in almonds. Studies have shown that amygdalin can hydrolyze to release benzaldehyde, which is the key component of almond aroma. In this study, the amygdalin and benzaldehyde content of fourteen sweet cultivars of almonds […]
Identification of almond (Prunus dulcis) vicilin as a food allergen.
Almond is one of the tree nuts listed by US FDA as a food allergen source. A food allergen identified with patient sera has been debated to be the 2S albumin or the 7S vicilin. However, neither of these proteins has been defined as a food allergen. The purpose of this study was to clone, […]
