AbstractIn this study, we developed a metal multilayer that can provide hermetic sealing after degassing the assemblies and absorbing the residual gases in the package. A package without a leak path was obtained by the direct bonding of the Au/Pt/Ti layers. After packaging, annealing at 450 °C caused thermal diffusion of the Ti underlayer atoms to the inner surface, which led to absorption of the residual gas molecules. These results indicated that a wafer coated with a Au/Pt/Ti layer can provide hermetic sealing and absorb residual gases, which can simplify vacuum packaging processes in the electronics industry.

With current meat industry efforts focused on improving environmental influencers, adopting sustainable packaging materials may be an easier transition to addressing the sustainability demands of the meat consumer. With the growing popularity of vacuum-packaged meat products, the current study evaluated instrumental surface color on fresh ground beef using vacuum packaging films, recycle-ready film (RRF), standard barrier (STB) and enhanced barrier (ENB). Ground beef packaged using ENB barrier film was lighter (L*), redder (a*) and more vivid (chroma) than all other packaging treatments during the simulated display period (p < 0.05). By day 12 of the simulated retail display, the ground beef surface color became lighter (L*), more yellow (b*), less red (a*), less vivid (chroma) and contained greater forms of calculated metmyoglobin, oxymyoglobin (p < 0.05). The current results suggest that barrier properties of vacuum packaging film for ground beef are pivotal for extending the surface color during fresh shelf-life conditions.

The use of essential oils (EOs) and/or vacuum packaging (VP) with meats could increase product shelf-life. However, no studies investigating the effect of EOs and VP on camel meat background microbiota have been conducted previously. The study aimed to analyze the antimicrobial effect of essential oils (EOs) carvacrol (CA), cinnamaldehyde (CI), and thymol (TH) at 1 or 2% plus vacuum packaging (VP) on the growth of spoilage-causing microorganisms in marinated camel meat chunks during storage at 4 and 10 °C. VP is an effective means to control spoilage in unmarinated camel meat (CM) and marinated camel meat (MCM) compared to aerobic packaging (AP). However, after EO addition to MCM, maximum decreases in spoilage-causing microorganisms were observed under AP on day 7. Increasing the temperature from 4 to 10 °C under AP increased the rate of spoilage-causing bacterial growth in CM and MCM; however, EOs were more effective at 10 °C. At 10 °C the maximum reductions in total mesophilic plate counts, yeast and molds, mesophilic lactic Acid bacteria, Enterobacteriaceae, and Pseudomonas spp. were 1.2, 1.4, 2.1, 3.1, and 4.8 log CFU/g, respectively. Incorporating EOs at 2% in MCM, held aerobically under temperature abuse conditions, delayed spoilage.

Telah dilakukan penelitian tentang pengaruh jenis material kemasan vakum dan non-vakum terhadap kualitas kadar air, dan organoleptik bakso aci pada penyimpanan suhu dingin. Tujuan Penelitian ini untuk mengetahui pengaruh kemasan bakso aci dengan penggunaan plastik Polietilen (PE) dan plastik nilon yang dikemas melalui teknik pengemasan vakum dan non-vakum pada penyimpanan suhu dingin. Serta untuk mendapatkan jenis kemasan yang tepat dalam penggunaannya terhadap kualitas bakso aci. Pengujian yang dilakukan meliputi uji kadar air dan uji organoleptik. Metode analisa statistik yang digunakan berupa Rancangan Acak Lengkap (RAL) untuk mendapatkan hasil yang lebih baik dan tidak terjadi kesalahan yang signifikan. Penelitian yang dilakukan menggunakan RAL dengan 4 perlakuan dan 2 kali pengulangan. Pengolahan data yang dilakukan dengan software SPSS (Statistical Product and Service Solutions) menggunakan metode ANOVA ( Analysis of Variance) dan uji lanjut Duncan untuk Uji kadar air dan menggunakan Kruskall Walls dan uji lanjut dengan Mann- Whitney untuk uji organoleptik terhadap kenampakan, aroma dan tekstur. Pengujian organoleptik mengikuti standar SNI untuk Bakso dengan 10 orang panelis tak terlatih. Berdasarkan penelitian yang dilakukan didapatkan hasil bahwa kadar air terendah yaitu dengan penggunaan kemasan  polietilen (PE) teknik pengemasan Vakum dengan nilai 2,35. Hasil untuk pengujian Organoleptik, yang dapat disimpulkan dari segi kenampakan, aroma dan tekstur perlakuan yang terbaik adalah dengan penggunaan jenis kemasan polietilen, dengan teknik pengemasan vakum dan jenis kemasan nilon dengan teknik pengemasan vakum yang mampu meyimpan dengan baik hingga hari ke-8. Research has been carried out on the effect of vacuum and non-vacuum packaging materials on the quality of water content and organoleptic properties of tapioca meatballs in cold storage. The purpose of this study was to determine the effect of meatball tapioca packaging with the use of polyethylene (PE) plastic and Nilon plastic packaged through vacuum and non-vacuum packaging in cold storage. As well as to get the right type of packaging in its use on the quality of tapioca meatballs. The tests carried out included water content tests and organoleptic tests. The statistical analysis method used was a completely randomized design (CRD) to get better results and there were no significant errors. The study was conducted using RAL with 4 treatments and 2 treatments. Data processing was carried out using SPSS (Statistical Product and Service Solutions) software using the ANOVA (Analysis of Variance) method and Duncan's further test for moisture content testing and using Kruskall Walls and further testing with Mann-Whitney for organoleptic tests on appearance, aroma and texture. The organoleptic followed the SNI standard for Meatballs with 10 panelists not being tested. Based on the research conducted, it was found that the lowest water content was the use of polyethylene (PE) packaging with a vacuum packaging technique with a value of 2.35. The results for organoleptic testing, which can be guaranteed in terms of appearance, smell and treatment are the best by using polyethylene packaging, with packaging techniques and Nilon packaging types with vacuum packaging techniques which are able to store well until the 8th day.
