Walnut (Juglans regia L.) is the oldest fruit grown in world and grows spontaneously almost throughout Romania. In this study, physical properties chemical composition of twenty types walnuts from three different locations Romania were studied. The analyzes that performed were: walnut dimensions shape (nut diameter, nut length, size), (walnut weight, kernel weight percentage kernel) external ex...

Walnuts are an economically important forest tree used for timber and nut production, the of fruits is rich in various nutrients, becoming one four nuts world. have deep roots, which can be colonized by either ectomycorrhizal fungi or arbuscular mycorrhizal soil. These form beneficial symbioses roots walnut. A large number been identified, whilst Boletus edulis, Calvatia uiacina, Cantharelles c...

Abstract Liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) was used for the rapid quantification of multiple mycotoxins, specifically aflatoxins B 1 , 2 G and (AFB AFB AFG ), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), in walnuts, pistachios, peanuts, coffee beans, rice, chickpeas from various countries. Total counts fungi, Aspergillus flavus, parasiticus were also asse...

Near-infrared spectroscopic data, used for non-destructive product identification, are traditionally processed using multivariate data analysis techniques. However, these methods often cover only a limited variability. We target the development of novel machine learning based algorithm enabling identification foreign objects, in combination with food safety and quality evaluation stream, by com...

What is thousand cankers disease of walnut? Thousand caners disease (TCD) is a newly recognized disease (2008) of certain walnut species (Juglans) caused by a fungus (Geosmithia morbida) that is vectored by a bark beetle (Pityophthorus juglandis, the “walnut twig beetle”).
