Phenolic extracts from colored-walnut pellicles: antioxidant efficiency in walnut oil preservation

Quality Evaluation of Walnut Oil through HPLC and in Vitro Antioxidant Activity

In the present study, a highly sensitive and simple high-performance liquid chromatographic method was developed and validated for simultaneous determination of three unsaturated fatty acids, αlinolenic acid, linoleic acid and oleic acid in walnut oil. Unsaturated fatty acids were quantified through HPLC using a reversephase C8 column and UV detector. Besides, the antioxidant activity of walnut...

Walnut Research in France

Walnut research in France is carried out by scientists employed by the Centre Technique Interprofessionel des Fruits et Legumes (CTIFL) and the Institute National de la Recherche Agronomique (INRA). (The Association Foret-Cellulose (AFOCEL) which has been active in research on walnut propagation is terminating their walnut project this year.) CTIFL focuses on applied research and technology tra...

Lipid analysis of Greek walnut oil (Juglans regia L.).

The walnut oil (Juglans regia L.) total lipids (TL) were extracted by the Bligh-Dyer method and the lipid classes have been isolated by chromatographic techniques and they were analyzed by high performance thin layer chromatography (HPTLC)/FID and GC-MS. The oil was found to be rich in neutral lipids (96.9% of total lipids) and low in polar lipids (3.1% of total lipids). The neutral lipid fract...

Impact of Walnut Scale Infestation on Walnut Quality and Yield

A study to mea~ure the effect of walnut scale infestation on English walnut qualityand yield has shown no differences in yield and no consistentdifferencein kernel quality between infested and non-infested trees for the four years ~f the study. Yield and quality of English walnut are not overly sensitive to walnut scale infestation and some degree of infestation can be tolerated with no measura...
