in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

In recent years, the use of edible coatings as a carrier of food additives and antimicrobial compounds in fishery products has been considered. This study was carried out to evaluate the effects of 2% chitosan coating singly or combined with 0.1% grape seed extract (GSE) on microbial (mesophilic and psychrophilic count), chemical (TBA, pH and PV) and sensorial properties of rainbow trout fillet...

application of edible coating as a way of prolonging the shelf-life of perishable fruits and vegetables is promising. two plum cultivars (stanley and giant) were treated with 1% chitosan and then stored at 0-1oc and relative humidity of 90±5% for 40 days. changes in weight loss, respiration rate, fruit firmness, soluble solid content, titrable acidity, ph, ascorbic acid as well as decay rate we...

The objective of present study was to evaluate the effects of the application of chitosan and chitosan/whey protein on the chemical, microbial and organoleptic properties of Göbek Kashar cheese during ripening time (on 3(rd), 30(th), 60(th) and 90(th) d). Difference in microbiological and chemical changes between samples was found to be significant (p<0.05) during ripening period. Cheese sample...

Abstract Sapodilla fruit ( Manilkara zapota ) is one of the annual tropical plants that have a shelf life only 3-4 days at room temperature. One way to extend by coating. Chitosan has an excellent potential be applied as edible The addition essential oils, namely Vanilla and Betel, expected improve characteristics coating act antimicrobial antioxidant. This research was conducted using Chitosan...

Antimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservati...

application of edible coatings to enhance storage life of fresh fruit has recently been under considerable attention. this experiment was conducted in order to explore the effect of chitosan coating and storage temperature on the postharvest life of pomegranate (punica granatum l.) fruit. therefore, pomegranate fruits ‘rabbab-e-neyriz’ were dipped in 0, 1 and 2% aqueous chitosan solutions, air ...

introduction: in iran, the main problem in greenhouse cucumber production and post-harvest shelf life is short due to the application of traditional packaging and storage methods. this research was carried out in order to investigate on the effects of packaging type and chitosan edible coating on the physicochemical and sensory characteristics of royal greenhouse cucumber during storage conditi...

Nanochitosan is a nanoparticle of chitosan with size between 100-400 nm. has higher antibacterial ability than ordinary chitosan. The manufacture into nanochitosan can be done by ionic gelation method, namely the complexation polyelectrolyte positively charged and negatively sodium tripolyphosphate. morphology in form whole sphere typical functional groups such as amine, hydroxyl carboxyl group...
