        The purpose of this study was to analyze the current status relating to food packaging and design for status of small and medium food enterprises. A company survey was conducted from June to October, 2015 and targeted 1300 small and medium domestic food enterprises. Finally, a total of 1300 (recovery rate 100%) useable data were selected. Statistical analyses were performed on the data utilizing the SPSS PASW Statistics 18.0 for Windows, such as descriptive statistics and frequency analysis. According to the results, awareness and importance of food labeling were high, but performance of English inscription of product name was relatively low. The most important reason for food labeling was ‘providing correct information on food’ 910 (72.8%). Accordingly, a system which can provide the latest information by continuously monitoring mandatory disclosure requirements for types of foods in individual countries is needed.

        Quality changes of carrots thermally processed in a large size (5 kg) retort pouch during 52 weeks of storage were investigated under different packaging methods and package shapes. To improve the efficiency of thermal processing (121.1oC, 0.15 MPa), the carrot (i.e., solid) and the broth (i.e., liquid) of the carrot soup were separately packed and sterilized. The quality changes of carrot packed without liquid were compared with those with liquid. Two different package shapes such as rectangular parallelepiped and cube were also evaluated to figure out the efficiency of the heat penetration rate for a large-sized pouch. The TTT (F0-values = 6) were 27, 54, and 114 min from the rectangular parallelepiped, cube, and solid/liquid mixed groups, respectively. In the mixed groups, the hardness and chewiness of solids (carrot) were significantly smaller than those measured in the other groups as TTT increased. Carrots treated in the rectangular parallelepiped shape showed a significantly higher texture than the cube shape. The CV of hardness and chewiness in the rectangular parallelepiped and the cube shape were calculated as 7.56 and 47.19, and 29.16 and 65.28, respectively. This demonstrated that a more uniform quality can be obtained from the rectangular parallelepiped shape.

        Quality changes of carrots thermally processed in a large size (5 kg) retort pouch during 52 weeks of storage period were investigated upon different packaging methods and package shapes. To improve the efficiency of thermal processing (121.1°C, 0.15 MPa), the carrot (i.e., solid) and the broth (i.e., liquid) of carrot soup were separately packed and sterilized. The quality changes of carrot packed without liquid were compared with those with liquid. Two different package shapes such as rectangular parallelepiped and cube were also evaluate to figure out the efficiency of the heat penetration rate for the large size of pouch. The location of cold points and the total thermal processing time (TTT) were different upon the treatment. Fo-values, satisfying the TTT to at least 6 min, were 27, 54, and 114 min from the rectangular parallelepiped, cube and solid/liquid mixed group, respectively. In the mixed groups, the hardness and chewiness of solids (carrot) was significantly smaller than that measured in the other groups as TTT increased. Carrots treated in the rectangular parallelepiped shape showed a significantly higher texture than the cube shape for both immediately after the thermal treatment and during the storage period. Coefficient of variation (CV), which indicates the quality variation within the same treatment, of texture properties obtained from the outside and the center of the sample were compared to evaluate the quality variation within the same treatment. The CV of hardness and chewiness of the rectangular parallelepiped and the cube shape were calculated 7.56 and 47.19, and 29.16 and 65.28, respectively. This demonstrated that more uniform quality could be expected from the thermal treatment in the rectangular parallelepiped shape

        A novel nanocomposite LDPE film with UV protective properties was developed for active packaging applications. Initially, undoped and Mn-doped TiO2 nanoparticles (NPs) were synthesized by the sol-gel method and the resulting particles were characterized. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed an agglomerated nature and spherical morphology. X-ray diffraction (XRD) studies indicated that all products were crystalline and in the form of rutile. The reflectance spectrum of undoped TiO2 NPs demonstrated a characteristic sharp edge at 410 nm. Subsequently, nanocomposite (NC) LDPE samples were prepared with the NPs by solvent precipitation followed by film casting. The optical and thermal properties of the NC samples were investigated. Incremental increases in Mn concentration from 0.25 mol % to 1.00 mol % were associated with progressive decreases in light transmission in the UV region. The melting and maximum decomposition temperatures of all NCs were 107 and 442-449 °C, respectively. The UV protective LDPE-based NC films exhibited superior photostability. Absorption in the FTIR spectra at 1716 and 1734 cm-1 changed after 4-wk exposure to UV for all film samples as a consequence of photodegradation. Finally, the photooxidation of perilla oil was assessed as an example of a UV protective packaging application. After 12 days, protection with 1.00 mol% Mn-doped TiO2-LDPE was associated with a gradual increase in PV, while protection with TiO2-LDPE was associated with a significant increase and protection with the control treatment was associated with a dramatic increase in PV. Hence, a 1.00 mol% Mn-doped TiO2-LDPE NC showed promise for UV shielding packaging applications.

        Antioxidant packaging have been investigated for a very long time, since lipid oxidation may cause a lot of quality problems which are not just on lipids but also to other components of food during storage and transportation. Lipid oxidation of packaged food can be by partly excluded by adding antioxidants to the packaged food, however, in order to make sure sustain release of antioxidant in a relatively long term and avoid food safety problems concerned by consumers, controlled release antioxidant active packaging, on the basis of active packaging, has been introduced and investigated. Controlled release packaging (CRP) means that active compounds release from packaging materials in a controlled manner which offers a prolonged delivery of active compounds at predictable and reproducible release rate. This study focuses on three subject in regard to the realized methods of controlled release of antioxidants in food packaging, which include encapsulation of active compounds with a mesoporous matrix, modification of structure and composition of multilayer film, and preparation of hydrogel bio-based packaging polymers.

        Along with the rapid development of China’s economy, the consumption of China’s consumer has also been increased. This research explores whether China’s consumers concern about product’s packaging as much as product’s quality and brand influence. It also discusses whether the product packaging is marked with recyclable logo on it and whether the packaging is harmful to human health. China’s express industry is taken as an example in this research. According to the statistics by State Post Bureau, the total amount of China’s express business was 14 billion packages in 2014, and the volume was substantially increased to 20.67 billion packages. If each package was estimated as 0.2 kg, more than 4 million tons of packaging waste would come from 20 billion packages. Recyclable packaging material would reduce the amount of waste and alleviate environmental pollution. However, whether customers are willing to pay for it is a problem. Product packaging can’t only attract customers from the visual perspective, but needs to be developed through multi-dimensional sensory conveying method. The product itself can be expressed directly through simple packaging. For instance, the Apple Inc. does not only shift consumer’s thoughts on mobile phone, meanwhile, it makes a change on high-end brand mobile phone packaging for China’s consumers. Prior to the emergence of Apple mobile phone, high-end mobile phone brand was adopted luxurious and sophisticated packaging method. With the entrance of Apple into China’s market, the unique style of Apple’s simplicity is followed by other mobile phone brands. This research is elaborated on China’s consumer’s reaction on innovative ecological packaging and their cognition to food packaging security. It also gives inspiration to enterprises how to catch consumer’s eyeballs through innovative ecological packaging and further make enterprises access to benefits.

        In the food industry, freezing storage has been an important process for maintaining the properties of food materials. In order to maintain the quality of blanched Colocasia esculenta (L.), Schott stem, packaging, freezing, and thawing methods were optimized by determinations of the physicochemical properties. For the comparison of packaging method, Colocasia esculenta (L.) Schott stem packed by air containment had the lowest significant differences of properties such as hardness and drip loss compared to the control samples. Overall, the drip loss of Colocasia esculenta (L.) Schott stem had lower value at fast freezing rate (immersion freezing). Considering the result of the drip loss, high frequency thawing was more effective than other thawing methods. Therefore, it was supposed that samples treated by air-containing packaging, immersion freezing, and high frequency thawing used the optimal method to maintain the original quality of Colocasia esculenta (L.) Schott stem.

        Food freezing preservation is an important process due to its high quality and long shelf-life. In order to improve the quality of frozen sweet potato stem, the freezing rate, thawing, and packaging method was optimized by the determination of physical properties. There was no significant difference among the treatment of freezing rate. Further, the drip loss of sweet potato stem was higher at a relatively fast freezing rate (immersion freezing) than at slow freezing rate (natural convection freezing at -20 or -40oC). For the comparison of packaging methods, the aircontaining packaged sweet potato stem had the lowest significant differences from the result of color, pH, and hardness. From the result of the drip loss, the high frequency and microwave using thawing samples were more effective than room temperature and water thawing. Therefore, fast freezing and thawing rate with air-containing package were recommended to obtain the better quality of sweet potato stem.

        A simplified prerequisite program is a basic element for an effective HACCP system operating in small meat packaging plants. We analyzed current configuration of the prerequisite evaluation checklists and classified according to two categories of general hygiene management and prerequisite requirements. The general hygiene management items overlapping with non-HACCP plant evaluation items were excluded except for the high rate of non-compliances. Non-compliance rates were calculated to determine the weak points of the current prerequisite program operation, and the potential risk elements were included in the simplified prerequisite requirements. The data used for the analysis of non-compliance rates were from the HACCP accreditation evaluation inspection reports by the Korea Livestock Products HACCP Accreditation Service. Of the existing 54 evaluation items, we selected 37 core items as simplified prerequisite requirements for meat packaging plants. In addition, we recommended simple modification of the evaluation items, with one item for evaluation of one check point.

        This research was conducted to estimate the effect of packaging methods on the color and taste-related precursors in Hanwoo (Korean cattle) beef during aging. Following packaging with vacuum (VACP), low oxygen-modified atmosphere (LOMAP; 0% O2/20% CO2/80% N2) or vacuum skin+LOMAP (VSP+LOMAP), the loins and top rounds were aged at 2℃ for 14 days and lipid oxidation (TBARS content), surface color, glucose and lactate contents were measured. TBARS and glucose contents were not different by packaging methods in both loins and top rounds. The a* (redness), b* (yellowness) and C* (chroma) values were higher (p<0.05) in VACP-aged beef as compared to the other beef. Lactate content was significantly higher (p<0.05) in both LOMAP- and VSP+LOMAP-aged beef than in VACP-aged beef at day 14 of aging. These findings suggested that VACP was the most effective in maintaining color stability but LOMAP was more effective in maintenance of some taste-related precursor compared to VACP.

        The short-grain rice cultivar Choochung with a rough rice moisture content of 21% was air-dried to equilibrate themoisture content to 15, 16, and 17%. After dehulling, brown rice was packaged for storage in laminated paper orLDPE/OPP plastic-film bags (10-kg size). After storage of the packaged rice kernels in plastic and paper bags at10, 15, and 20oC, the quality characteristics of the rice were evaluated weekly for 16 weeks. Serious losses in theinternal moisture content of the kernels were observed during storage in paper bags, regardless of the moisture con-tent of the kernels or the storage temperature. The plastic-film packaging was effective in maintaining the weightof the kernels for all treatments, but severe fat oxidation problems were encountered, especially when the initialmoisture content of the kernel was 17% and/or the storage temperature of the kernels was 20oC. Before two weeks,the fat acidity value of the kernels reached 20mL KOH/100g, a marginal limit for an acceptable taste of cookedrice. Based on this study, the recommended environment for the storage of brown rice for efficient economic storageof the kernels is an initial kernel moisture content of 16%, laminated plastic-film packaging, and a sub-refrigerationtemperature of 15oC.
