Exploring The Impact Of Vented Packaging Configurations On Airflow Patterns And Cooling Consistency For Muskmelons In A Cold Storage Environment, Nur Wafidah Roslan, Namasivayam Navaranjan, Zohrah Sulaiman, Naseem Uddin

ASEAN Journal on Science and Technology for Development

The cooling effect of different vented packaging designs was investigated for packed muskmelons fruits in a commercial cold storage condition. Computational fluid dynamics (CFD) simulation and experiments were used. The airflow pattern, heat transfer and temperature profiles were predicted from simulation and analysed. The CFD results reveal an uneven and low efficient airflow distribution inside a commercially used vented packaging (Box A). This resulted slow cooling of the fruits in Box A. Two newly designed packaging (Box B and Box C) showed better airflow distribution around the fruits and cooled them faster than Box A. The design of Box C …

Effects Of Period And Temperature On Quality And Shelf-Life Of Cucumber And Garden-Eggs Packaged Using Cassava Starch-Zinc Nanocomposite Film, Adeshina Fadeyibi, Zinash Delebo Osunde, Mohammed Gana Yisa

Journal of Applied Packaging Research

Nanocomposite film can be used to prolong the shelf-life of fruits and vegetables. This research was undertaken to investigate the effects of packaging period and temperature on the quality and self-lives of cucumber and garden-eggs packaged using cassava starch-zinc nanocomposite film. Hundred grams each of cucumber and garden-eggs were wrapped in a 200× 350 mm size nanocomposite film and low density polyethylene (LDPE) of 2.240± 1.076 × 10^-10 gm^-1Pa^-1s^-1 water vapor and 1.568± 0.084× 10^-10 gm^-1Pa^-1s^-1 oxygen gas permeability. The products were stored at 10−27^oC temperatures …

Developments And Properties Of Plastic Mimicking Biopolymers For Food Packaging Application, Daniel I. Hefft

Journal of Applied Packaging Research

Sustainability takes an ever increasing importance in the food industry. Here not only the selection of raw materials plays a role, but also packaging materials. Nowadays there is an increasing number of biodegradable and bio-compostable packaging materials available.

However, these materials are still not able to replace mineral oil based packaging materials completely, nevertheless they are becoming increasingly important, since there must be solutions to problems such as pollution of the oceans by plastic waste, growing piles of rubbish from growing population, etc.

The following literature review shows briefly recent developments on plastic mimicking biopolymers, as these materials guarantee great …

Efficacy Of Natural Plant Extracts In Antimicrobial Packaging Systems, Kofi Jocelyn Brobbey, Jarkko J. Saarinen Adj. Prof., Hanna-Leena Alakomi Dr., Baoru Yang Prof., Martti Toivakka Prof.

Journal of Applied Packaging Research

Antimicrobial plant extracts used in food packaging provide a healthy packaging alternatives. They contain aromatic and phenolic compounds that are responsible for their antibacterial properties. In this study, we report the antibacterial effects of extracts obtained from sea buckthorn (Hippophaë rhamnoides L.) leaves, and inner bark of pine trees (Pinus silvestris) that were applied as coatings on paper suitable for packaging application. Extracts from sea buckthorn leaves exhibited antibacterial effect both as a solvent extract and as a coating on paper against Pseudomonas aeruginosa as test bacteria. However, coatings of pine bark extract did not exhibit …

Producing Food Packaging Printing Ink Via Green Emulsion Aggregation Method, Maryam Ataeefard, Shohre Rouhani

Journal of Applied Packaging Research

Digital printing will become more and more important in the packaging industry. Digital printing technology is growing because it allows the print suppliers to improve the level of service they offering to their customers, as well as, it opens new opportunities and helps them to make more money. Additives, dyestuffs, resin and other chemicals in packaging printing ink may influence safety of the food. Therefore, choosing suitable materials are very important in food packing ink. Over the last years, many printing ink manufacturers moved toward more sustainable inks. Drivers for this development, besides the resource scarcity and a higher legislative …
