A printable time temperature integrator (TTI) consisting of oxygen indicator and cover films with various oxygen permeability was developed. The printing ink contained methylene blue (oxygen indicator) which changed in color during storage. TiO2 and glycerol for UV-activation of TTI and zein and ethanol for printing performance were also contained in the printing ink. The cover film on the ink was employed to control the color change rate and temperature dependency (Arrhenius activation energy, Ea) by using the different films (PE, PET, OPP, and LLDPE). The film properties were varied by annealing. TTI was produced by silk screen printing. As a result, the color change rates were different for the cover films, being the highest in TTI with LLDPE, followed by OPP, PE, and PET. The rate decreased with increase in the cover film thickness. The Ea was the highest in TTI with LLDPE, followed by OPP, PE, and PET. The Ea did not change with the cover film thickness. The annealed PVC and PET film were lower in oxygen permeability than the unannealed ones, indicating the lower color change rate.

A novel printable time-temperature integrator (TTI) composed of a natural coloring matter, anthocyanidin, was developed. The anthocyanin was biochemically modified to change in color over week scale, compared to the original anthocyanin over month scale change. The anthocyanin extracted from strawberry was converted to its aglycone, anthocyanidin, by the treatment with β-glucosidase. The print paste was composed of the freeze-dried powder of anthocyanidin, pullulan, glycerol and distilled water, which was screen-printed. The TTI performance were examined in terms of kinetics and temperature dependency. The activation energy of anthocyanidin TTI was 86.92 kJ/mol. Compared with the activation energy of foods, the applicable food groups were found. Applicable food groups were chilled meat products and fish. The major benefits of the TTI were the printability to be practical in use and the eco-friendliness with the natural pigment.

This article delves into the current status of various packaging technologies, which are currently being applied or are under development for the shelf-life extension and quality improvement of fresh and processed meat products. Traditional packaging methods include vacuum packaging, modified atmosphere packaging, and air-permeable packaging. Recently, innovative packaging methods have been introduced that utilize technologies such as barrier-films, active packaging, nanotechnology, microperforated films, far-infrared radiations, and plasma treatment. All of these packaging methods have their own merits and drawbacks in terms of shelf-life and quality maintenance. A right choice of packaging system for fresh and processed meat products must be made in accordance with the conditions of the raw material, storage, and distribution in the market and household, and while considering the environmental sustainability and consumer’s expectations.

Paper packs, glass bottles, metal cans, and plastic materials are classified according to packaging material recycling groups that are Extended Producer Responsibility (EPR). In the case of waste paper pack, the compressed cartons are dissociated to separate polyethylene films and other foreign substance, and then these are washed, pulverized and dried to produce toilet paper. Glass bottle for recycling is provided to the bottle manufacturers after the process of collecting the waste glass bottle, removing the foreign substance, sorting by color, crushing, raw materializing process. Waste glass recycling technology of Korea is largely manual, except for removal of metal components and low specific gravity materials. Metal can is classified into iron and aluminum cans through an automatic sorting machine, compressed, and reproduced as iron and aluminum through a blast furnace. In the case of composite plastic material, the selected compressed product is crushed and then recycled through melt molding and refined products are produced through solid fuel manufacturing steps through emulsification and compression molding through pyrolysis. In the recycling process of paper packs, glass bottles, metal cans, and plastic materials, the influx of recycled materials and other substances interferes with the recycling process and increases the recycling cost and time. Therefore, the government needs to improve the legal system which is necessary to use materials and structure that are easy to recycle from the design stage of products or packaging materials.

This study sought efficiency of collaboration between manufacturers and distributors by finding a way to improve logistics efficiency in order to save distribution cost and standardize packaging together with profit generation by way of simple-display packaging in discount stores. For the study purpose, the impact of products with RRP (Retail Ready Packaging) by each discount store on the collaboration achievement such as loading efficiency was observed. From this observation, an alternative packaging system that can improve logistics efficiency between manufacturers and distributors was sought and the role of distributors in distribution standardization was explored. The purpose of this study also includes suggesting some implications on future basic direction of environment-friendly management. If this study would induce distributors to have more interest in distribution standardization and if logistics efficiency would be enhanced by the operation of packaging system considered of compatibility with pallets, this study would have academic significance and create practical values.

The effects of distribution temperature due to season all changes on quality and storability of baby leaf beet (Beta vulgaris L.) was examined in modified atmosphere (MA) packages. The beet leaf had been harvested at the 10 cm leaf length stage and packaged with an oxygen transmission rate (OTR) film of 1,300 cc·m-2·day-1·atm-1 and then held at 4 different distribution temperatures which were -2oC, 4oC, 20oC, or 30oC for 5 hrs and then stored for 18 days at 8oC. The loss of fresh weight of packged baby leaf beet was lowest at the 4oC treatment, and below 0.6% in all distribution temperature treatments. The atmosphere composition in packages did not show any significant differences among treatments. The oxygen conc. was the highest at 18.0% after the 4oC treatment, carbon dioxide conc. showed the maximum value of 4% at the 30oC and -2oC treatments, and ethylene conc. was highest at the 10oC treatment after 10 days in storage. The hardness was the highest at the 4oC treatment on the final storage day. The 4oC treatment showed the highest visual quality and the lowest off-odor and aerobic plate count. Therefore, it is necessary to establish a low-temperature distribution system which is controlled under 4oC, because the baby leaf beet’s storability and microbial growth are effected even during a short time of 5 hrs during the distribution process.
