Food packaging films

Ebook "Packaging for food preservation (Food engineering series)" will be focused on the three most important aspects of food packaging: Modeling, Materials and Packaging Strategies. The modeling section will provide a complete overview of mass transport phenomena in polymers intended for food packaging applications. The materials section will cover the most interesting problem-solving solutions in the field of food packaging, i.e., low environmental impact active films with antimicrobial activity.

Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it has widely been used in food packaging over the last many years. To increase the suitability of PVA (C2H4O)n and render it ideal for food packaging, a diversity of studies have already been carried out. In the below-mentioned script, we, for the first time, report the use of natural product osthol in making a new composite with PVA for enhancing thermal, physicochemical, and antimicrobial properties.

This study uses sunflower hulls, a by-product from the sunflower snack industry, to recover both, valuable phenolic compounds and cellulose fibers, for the production of antioxidant reinforced starch films as potential food packaging material. The phenolic extract provided antioxidant properties to the films with EC50 values of 89 mg film/mg DPPH.

This work investigated the effect of adding low concentrations of nano-SiO2 (0.5, 1.0 and 1.5%) in the properties of films based on sodium alginate, to identify lower thresholds in the proportion of the reinforcing agent. It was found that, even in the smallest proportion, thermal stability of the nanocomposites improved significantly (with degradation onset increased by almost 15% compared with the control film).

The bioactive properties of cooked and uncooked pulp of Solanum lycopersicum (tomato) were studied. Both cooked tomato pulp (CTP) and uncooked tomato pulp (UTP) had high total phenolic and flavanoid content and antioxidant activity was ascertained by various invitro assays. Gram positive organisms were sensitive to CTP and UTP but the extracts were ineffective against Gram negative bacteria.

In Today’s scenario, various food industries use harmful packaging materials like plastics, metal, paper and combination of more than one material or composites. Approximately, 60% of plastics are being used in packaging and almost half of that is used to pack food-products, which is very dangerous for human health. Plastic is non-biodegradable and is not safe for food packaging and causes various health hazards. Plastic also reduces moisture and oxygen transfer rate of soil and deteriorates the quality of soil.

Edible coatings or films have received considerable attention in recent years. Materials used in edible packaging (polysaccharide, lipid and protein-based and their composites) have apparent advantages over synthetic films. It could contribute to the reduction of environmental pollution. The main advantage of edible films over synthetics is that these may be safely eaten as a part of the food products and are environment-friendly at the same time as they increase the shelf life of fresh products.
