In this study, the effects of coatings made of chitosan (Chi) incorporating thyme essential oil (TEO) on lipid oxidation and changing color indexes of walnut kernels were investigated. Chi: pure, in accompany with TEO at concentrations of 500 and 1000 microliter per liter, in an aqueous coating solution, with different packaging methods: Gunny sack, polypropylene and active packaging, compared ...

Late spring frost is one of the most important factors causing loss of production of the Persian walnut (Juglans regia L.). Therefore, the selection of spring frost tolerant genotypes has been among the most important priorities in the breeding programs during the recent years in Horticultural Science Research Institute, Karaj-Iran.  After the spring frost in 2010, five superior genotypes (B10,...

For at least the past decade, an unusual decline of black walnut (Juglans nigra) has been observed in several western states. Initial symptoms involve a yellowing and thinning of the upper crown, which progresses to include death of progressively larger branches (Figure 1). During the final stages large areas of foliage may rapidly wilt. Trees often are killed within three years after initial s...

AIM Identification of cyclopropyl fatty acids in walnut oil. METHOD GC/MS method was developed for the determination of eight cyclopropyl fatty acids in walnut (Juglans regia) oil. RESULTS Monocyclopropane acids: methyl 9-cyclopropyl-nonanoate, 6,7-methylene-, 8,9-methylene-, 9,10-methylene-, 11,12-methylene octadecanoates, and dicyclic acid - methyl 9,10,12,13-dimethylene octadecanoate, tr...

dehulling is an important step in walnut processing that has considerable effect on the quality, chemical and microbial properties of walnuts. improving dehulling can increase the quality of the final product. this research studied the effect of genotype and hulling method on walnut properties. one experiment was performed as a factorial in a randomized complete block design with three replicat...

In this study, walnut green husk extract, which is a valuable waste of horticultural products, was used to enhance antioxidant properties and reduce microbial load of ketchup sauce. Extraction efficiency of walnut green husk extract 22.01%, total phenolic compounds 65.40 (mg gallic acid per 100 g dry husk), flavonoids 10.06 (catechin mg per 100 g dry husk), and EC50 0.17 (mg/mL) were expressed....
