The main objective of this study was to identify compounds that contribute the bitter taste attributes American hazelnuts (C. americana) and derived hybrids. Sensory-guided Prep-LC fractionation analysis selected four as were further identified by MS NMR carpinontriol B, 2-(3-hydroxy-2-oxoindolin-3-yl)acetic acid 3-O-6′-galactopyranosyl-2″-(2″oxoindolin-3″yl) acetate, giffonin-2-O-[(α-d-glucopy...

This study focuses on the detectable metabolome of high-quality raw hazelnuts (Corylus avellana L.) and its changes after dry-roasting. Informative fingerprinting was obtained by comprehensive two-dimensional gas chromatography with fast-scanning quadrupole mass spectrometry (GC×GC-qMS) combined dedicated data processing. In particular, untargeted targeted (UT) fingerprinting, based pattern rec...

Abstract Certain species of acorn- and nut-feeding weevils, Curculio spp. (Coleoptera: Curculionidae), have become significant insect pests cultivated hazelnuts (Corylus spp.) (Fagales: Betulaceae) worldwide. The significance weevils that feed on injure is increasing as countries such the United States China continue to develop hybrids hazel plants increase their hazelnut production. This revie...

The aim of this study is to apply the Nutrient Analysis Critical Control Point (NACCP) process to ensure that the highest nutrient levels in food can determine a beneficial effect on the health of the consumer. The NACCP process involves a sequence of analysis and controls that depart from raw material production to the evaluation of the effect of nutrition on health. It is articulated through ...

Observational studies suggest nut consumption is inversely associated with the incidence of cardiovascular disease and cancer. In addition to being rich in several vitamins and minerals, unsaturated fatty acids, and fiber, tree nuts and peanuts contain numerous phytochemicals that may contribute to promoting health and reducing the risk of chronic disease. While many of these bioactive constitu...

Nano packaging is currently one of the most important topics in food packaging technologies. The aim of the application of this technology in food packaging is increasing shelf life of foods by preventing internal and external corruption and microbial contaminations. Use of silver nanoparticles in food packaging has recently attracted much attention. The aim of this study was to investigate the...

Acrylamide is a carcinogenic and neurotoxic compound defined as heat treatment process contaminant. Due to its health concern, acrylamide formation needed be minimized. The objective of this study examine how much contained in dried almonds (Prunus dulcis), hazelnuts (Corylus avellana), pistachios (Pistacia vera), peanuts (Arachishypogaea), sunflower seeds (Helianthus annuus) well pumpkin (Cucu...
