Almond oil: A comprehensive review of chemical composition, extraction methods, preservation conditions, potential health benefits, and safety.
Almond oil, a rich source of macronutrients and micronutrients, is extracted for food flavorings and the cosmetics industry. In recent years, the need for high-quality and high-quantity production of almond oil for human consumption has been increased. The present review examines the chemical composition of almond oil, storage conditions, and clinical evidence supporting the health […]
Post-harvest industrial processes of almond (Prunus dulcis L. Mill) in Sicily influence the nutraceutical properties of by-products at harvest and during storage.
Almond cultivation in Sicily is experiencing a phase of great interest which is mainly concentrated in the development of specialized orchards, with irrigation and by adopting cultivars with high qualitative and quantitative performances. These are mostly Mediterranean genotypes with high fat content and hard or semi-hard shell, extremely different from the varieties of Californian diffusion. […]
Contamination by Aflatoxins B/G in Food and Commodities Imported in Southern Italy from 2017 to 2020: A Risk-Based Evaluation.
This study reports the results of aflatoxins B/G monitoring in food of vegetal origin, imported in Southern Italy from extra-European Union countries. From 2017 to 2020, we analyzed 1675 samples using an accredited HPLC method with fluorescence detection. We found out 295 samples (17.6%) were contaminated by aflatoxin B1, 204 by aflatoxins B/G (12.2%), while […]
Fraud Detection in Batches of Sweet Almonds by Portable Near-Infrared Spectral Devices.
One of the key challenges for the almond industry is how to detect the presence of bitter almonds in commercial batches of sweet almonds. The main aim of this research is to assess the potential of near-infrared spectroscopy (NIRS) by means of using portable instruments in the industry to detect batches of sweet almonds which […]
Minimal changes in telomere length after a 12-week dietary intervention with almonds in mid-age to older, overweight, and obese Australians: Results of a randomised clinical trial.
Diet is a modifiable risk factor for chronic disease and a potential modulator of telomere length (TL). The study aim was to investigate associations between diet quality and TL in Australian adults after a 12-week dietary intervention with an almond-enriched diet (AED). Participants (overweight/obese, 50–80 years) were randomised to an AED (n 62) or isoenergetic nut-free […]
Almond consumption decreases android fat mass percentage in adults with high android subcutaneous adiposity but does not change HbA1c in a randomized controlled trial
The purpose of this study was to determine if the mixed evidence of almond consumption on HbA1c stems from testing people with different body fat distributions (BFD) associated with different risks of glucose intolerance. A 6-month RCT in 134 adults was conducted. Participants were randomly assigned to the almond (A) or control (C) group based […]
A Comprehensive Review of Almond Clinical Trials on Weight Measures, Metabolic Health Biomarkers and Outcomes, and the Gut Microbiota.
This comprehensive narrative review of 64 randomized controlled trials (RCTs) and 14 systematic reviews and/or meta-analyses provides an in-depth analysis of the effect of almonds on weight measures, metabolic health biomarkers and outcomes, and the colonic microbiota, with extensive use of figures and tables. Almonds are a higher energy-dense (ED) food that acts like a […]
Feeding high amounts of almond hulls to lactating cows.
California is the leading state for the production of almonds, with more than 400,000 bearing hectares of orchards that produced approximately 1 billion kg of shelled nuts in 2017. Almond hulls (AH) are a regional by-product feedstuff fed predominately to dairy cattle in California. A 2012 study surveyed 40 dairy farms in California and found […]
Acid hydrolysis of almond shells in a biphasic reaction system: obtaining of purified hemicellulosic monosaccharides in a single step.
The aim of this work is to comprehend the biphasic reaction systems through another perspective; the simultaneous purification and production of carbohydrates during the pretreatment of biomass. A dilute acid hydrolysis of almond shells in a 2-Methyltetrahydrofuran/H2O system was optimised to maximise the obtaining of hemicellulose-derived monosaccharides with the minimum formation of degradation products. The […]
A comprehensive review on different classes of polyphenolic compounds present in edible oils.
Edible oils are used as a frying medium and in the preparation of several food products. They are mainly constituting triacylglycerols as major components, while other compounds are classified as minor constituents, which include polyphenols. This class of compounds plays an important role in the thermal stability and quality attributes of the finished industrial food […]
