Insect‐Resistant Food Packaging Film Development Using Cinnamon Oil and Microencapsulation Technologies

Abstract

The insect-repelling effect of cinnamon oil incorporated into LDPE films was more effective with microencapsulation. The system developed in this research with LDPE film may also be extended to other food-packaging films where the same coating platform can be used. This platform is interchangeable and easy to use for the delivery of insect-repelling agents. The films can protect a wide variety of food products from invasion by the Indian meal moth.

Development of Natural Insect‐Repellent Loaded Halloysite Nanotubes and their Application to Food Packaging to Prevent Plodia interpunctella Infestation

“…From the results of (Figure and ), we hypothesized that HNTs/CO/LBL had a sustainable repellent activity against P. interpunctella larvae. According to the previous studies (Jo and others ; Kim and others ), the insecticidal effects of cinnamon oil were successfully evaluated. However, prolonged insecticidal effects and sustainable release profile were not determined in the previous studies.…”

“…A penetration test was conducted following the method of Kim and others () in order to determine the inhibitory effect of gravure‐printed LDPE films on invasion by Indian moth larvae. The test used 2 square acrylic plates (20 cm × 20 cm).…”

“…Packaging is the last defensive barrier that prevents food products from insect infestation during storage (Lange and Wyser ; Kim and others ). However, though packaging films are hermetically sealed, insects can still be attracted by strong olfactory cues and penetrate through packaging materials (Mohandass and others ), resulting in contamination.…”

Preparation, characterization, and oxygen scavenging capacity of biodegradable α‐tocopherol/PLA microparticles for active food packaging applications

“…A viable solution could get considering the great chances that microencapsulation techniques of sensitive compounds bring in several technological fields, e.g., pharmaceutical, food, agro‐chemical, etc. . However, at now only few papers report on the development of microparticulated oxygen scavenger systems based on natural compounds for food packaging applications .…”

Cinnamaldehyde and related phenylpropanoids, natural repellents, and insecticides against Sitophilus zeamais (Motsch.). A chemical structure‐bioactivity relationship

“…Although the use of chemicals with stronger repellent properties might reduce the development of resistance among storage‐insect pests, the large diversity of storage‐insect pests could result in variations in the responses to the same chemical. Taking this into account, a large number of different essential oils and their components were tested for repellence against storage‐insect pests . In previous reports, anethol, estragole, and eugenol have been shown to have repellent action against S. zeamais, although anethole also showed some attractive activity at low concentrations .…”
