In the present study, packaging of a greenhouse-grown tomato on the culture medium containing 0, 25, 50, 75 and 100% compost tea under modified atmosphere: MA (88%N2 + 8%CO2 + 4%O2) in polyethylene and nanosilicon-polyethylene bags was studied at 5°C for 30 days. Several quality parameters such as moisture content, pH, total soluble solids (TSS), titratable acidity (TA), Vitamin C content, text...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

Thyme Essential oils (EO) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. It is also used for flavoring and preservation of several foods. Nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. In this study Thymus ...

Watercress is a leafy vegetable of the family Brassicaceae that grows in and around water, it has a short shelf life (approximately seven days) and it is consumed raw or steamed. The objective of this work was to study the effect of packaging film and different storage temperature on the postharvest quality of watercress minimally processed. Treatments were: packed with plain film (PD961EZ, 31m...

 Background: Plastic and polymeric materials remain in the soil given the fact that they are derived from petroleum resources. However, such pollution has created a special challenge for human societies. The use of biodegradable packaging has received more attention. The general purpose of this study was to investigate the use of a mixture film of whey protein concentrate and reinforced hydroxy...

Polylactic acid (PLA) is a biodegradable and renewable polymer, which represents a valuable alternative to plastic packaging films, often associated with environmental problems. In this study, we tested the suitability of PLA as a biodegradable packaging film and assessed the antimicrobial activity of lemongrass oil (LO), incorporated into the PLA film in different concentrations. To obtain the...

The purpose of the present study was to evaluate carboxymethyl cellulose (CMC) coated polypropylene (PP) films containing Zataria multiflora (ZEO) essential oils (4%) as an antimicrobial packaging for chicken breast stored at 4 °C. To increase PP film hydrophilicity, it was treated by atmospheric cold plasma prior to coating by CMC. Then, different films including PP, PP/CMC, PP/CMC containing ...
