Gamma Irradiation for Fresh Produce

Effect of Chemical Treatments on the Quality of Fresh-Cut Globe Artichoke (Cynara Scolymus,L.) During Cold Storage

Globe artichoke (Cynara scolymus L.) is a perennial rosette plant grown throughout the world for its large, fleshy heads [1-3]. Most of its culture (about 90%) is concentrated in the countries around the Mediterranean Basin mainly in Italy (50 000 ha), Spain (17000 ha) and France (10 000 ha) [4]. Egypt has the potential to develop an excellent export industry in artichoke. The production areas ...

Hot air treatment delays senescence and maintains quality of fresh-cut broccoli florets during refrigerated storage

A postharvest treatment with hot air (48 C during 3 h) was applied to fresh-cut broccoli to investigate its effect on quality and senescence during storage at 0 C. The treatment delayed yellowing as evidenced by lower decrease of Hue values during storage. After 21 days of storage, treated broccoli had chlorophyll content approximately 40% higher than controls. The treatment did not affect eith...

Quality changes during storage of fresh-cut or intact Swiss chard leafy vegetables

Fresh-cut leafy vegetables have been gaining importance in the human diet both for their nutraceutical proprieties and low calories content. The preparation procedures for fresh-cut production and the storage system may lead to severe leaf damages that may affect leaf colour and induce shortened shelf life. The aim of this work was to study the leaf pigment changes in cut and whole Swiss chard ...

Effect of Gamma irradiation and frozen storage on microbial quality of Rainbow trout (Oncorhynchus mykiss) fillet

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...
