abstract leafy vegetables such as lettuce are more susceptible to post harvest losses, thus application desirable treatments can be recommendable. generally, type of packaging, such as modified atmosphere packaging (map) and wrapping can considerably suppress post harvest loss of horticultural products. in this study, the effects of polypropylene film (thickness 30 and 40 micron) wrapping and m...

Purpose – The purpose of this paper is to review the recent trends in the development of active packaging (AP) for foods. Design/methodology/approach – The most up-to-date and pertinent studies within the literature have been included and summated in this paper. Findings – Fresh foods are widely consumed and are becoming a major component of the international food market. During the last decade...

Chitosan films incorporated with various concentrations of gallic acid were prepared and investigated for antimicrobial, mechanical, physical and structural properties. Four bacterial strains that commonly contaminate food products were chosen as target bacteria to evaluate the antimicrobial activity of the prepared gallic acid-chitosan films. The incorporation of gallic acid significantly incr...

The main directions in food packaging research are targeted toward improvements in food quality and food safety. For this purpose, food packaging providing longer product shelf-life, as well as the monitoring of safety and quality based upon international standards, is desirable. New active packaging strategies represent a key area of development in new multifunctional materials where the use o...

118 Packaging is an indispensible vehicle to deliver products to consumers. The definition of packaging says that it is a co-ordinated system of enclosing food to protect it from tampering or contamination from physical, chemical and biological sources. Now a days consumer requires food that are fresh, mildly preserved, convenient and ready to serve. Per capita consumption of packaging material...

Methodology Active packaging material was low density polyethylene (LDPE) film incorporated with Tinuvin 326(UV absorber) and iron powder in different concentrations (0-0.5% and 0-15% w/w, respectively). Eleven treatments were performed according to the central composite design (CCD) in order to evaluate changes in mechanical, physical and barrier properties of films. Moreover, the influence of...

The composition and quality of packaging materials can have a critical impact on the performance, function, and production cost of pharmaceutical medications or drugs. Improper packaging can cause the active pharmaceutical ingredients (API) in medications to degrade faster, and have shorter shelf lives. Detecting problems, impurities, or incorrect polymer compositions early in the packaging pro...
