with the development of beverage industry and expansion of the markets , packaging of these products has also come out of its traditional form and intelligent packaging has been applied gradually. different types of smart packaging are used in the beverage industry such as gas release packaging which by gas production causes a good texture and is used in order to create a creamy milk coffee. in...

food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they demand ...

for button mushrooms packaging, the packaging films with high permeability to oxygen and carbon dioxide are required. permeability of plastic films such as pvc lead to loss of weight (and thus economic value) and textural changes are undesirable for button mushroom. so packaging film of polyolefins (pd 941 and pd 961) can be used. also the new film, hydrophilic materials such as films made from...

Modified atmosphere packaging (MAP) has become a popular method for packaging foods as it can extend the shelf life of food with minimal quality defect. Oxygen, nitrogen and carbon dioxide are the common gases used in MAP, Oxygen and carbon dioxide inclusive as only these two gaseous have the preservative effects on the packed food product. Their effect on microbial changes of any food product ...

In response to the dynamic changes in current consumer demand and market trends, the area of Active Packaging is becoming increasingly significant. Unlike traditional packaging, which must be totally inert, active packaging is designed to interact with the contents and/or the surrounding environment. Active packaging refers to the incorporation of additives into packaging systems with the aim o...

The aim of the present work was to evaluate the effects of 2 different packaging films on chemical, physical, and microbiological variables in veal calf meat. Slices from the right half carcass were sampled from each calf: 8 were packaged with Cryovac film (25 μm thick) and 8 were packaged with Weegal film (45 μm thick). In both packaging types, the same gas mixture was used. The samples were a...

Image analysis was applied to examine banana peel browning. The banana samples were divided into 3 treatment groups: no treatment and normal packaging (Cont); CO2 gas exchange packaging (CO); normal packaging with an ethylene generator (ET). We confirmed that the browning of banana peels developed more quickly in the CO group than the other groups based on sensory test and enzyme assay. The G (...

Changes in essential oils (EOs) content and composition of lemon verbena leave at different packaging methods (packaged with air, nitrogen, or under vacuum) and during storage period (0, 2, 4, 6 and 8 months) were determined. All the samples were hydrodistilled every 2 months during storage for EO content evaluation. EO composition was determined by gas chromatography and gas chromatography-mas...
