“…Joon Choi et al 13 prepared a clay‐supported catalyst by directly inserting catalyst into the clay interlayers through the metathesis reaction of sodium cations with chlorotitanium catalyst, then PET/clay‐supported catalyst nanocomposites were prepared by melt polycondensation, which showed excellent oxygen barrier properties. As food and beverage safety issues have been paid closer attention, active barrier of packaging has gradually become the focus of researches 14,15 . For example, the oxidation of unsaturated hydrocarbons in polymer matrix can play a role of oxygen scavengers 16,17 .…”

Hydroxy-terminated polybutadiene (HTPB) was grafted onto nanosilica via two steps, and then melt extruded with PET and transition metal catalyst. Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) results showed that HTPB successfully bridged to the surface of nanosilica through toluene-2,4-diisocyanate (TDI), and the grafting amount of HTPB accounted for about 11.2% of the total mass of nanosilica. The PET composite samples were also uniaxially stretched into films. Tensile results showed that the tensile strength of composite films was generally higher than that of composite sheets, especially the tensile strength of PET/SiO 2-HTPB composite film reached 139.8 MPa. After uniaxial stretching, the crystallinity of all films were significantly improved, and fillers accelerated the crystallization rate of PET, which greatly improved the crystallinity of composite materials, thereby contributing to the improvement of the oxygen barrier performance of composite materials. After adding the catalyst, the PET/SiO 2-HTPB/ Co composite film has the lowest oxygen permeability coefficient of 1.05 × 10 −15 (cm 3 Ácm/cm 2 ÁsÁpa), which was 87.6% lower than that of pure PET sheet. SEM showed that the compatibility between filler and matrix was improved. This study demonstrated that nanosilica grafted with HTPB played a synergistic role in improving the crystallinity of materials and exerting the active oxygen scavenging of HTPB, and uniaxial stretching was helpful for improving the comprehensive properties of composites.

“…Bandeng presto mengalami penurunan warna dari kuning keemasan yang ditunjukkan dengan nilai organoleptik 7-8 pada hari ke nol menjadi agak kusam. Hal ini dikarenakan keberadaan oksigen di dalam kemasan dapat menyebabkan penurunan warna akibat reaksi oksidasi (Gaikwad et al, 2018). Berdasarkan atribut kenampakan, bandeng presto baik yang dikemas vakum maupun non vakum masih dapat diterima panelis sampai penyimpanan hari ke 3.…”

Softbone milkfish is a fishery product that easily damaged during storage. One of the efforts to inhibit the damage of softbone milkfish was using vacuum packaging. The purpose of this study was to determine the changes quality of softbone milkfish which were vacuum packed during storage at room temperature. Fresh milkfish was heating with high pressure by using a pressure cooker. Softbone milkfish was then stored at room temperature for six days. Analysis was carried out every three days for the parameters of free fatty acids, TVBN, and organoleptics. The results showed that the number of free fatty acids and TVBN increased during storage. Free fatty acids and TVBN of softbone milkfish with vacuum packaging after sixth days of storage were 2.95% and 15.95 mgN/100g, respectively. This value was lower than the non-vacuum softbone milkfish. Based on organoleptic analysis, softbone milkfish with vacuum packaging was still suitable for consumption until the third day of storage. This showed that vacuum packaging can extend the shelf life of softbone milkfish.

“…CAT catalyzes hydrogen peroxide disproportionation to release water and molecular oxygen as innocuous products . Such a catalytic reaction makes this enzyme industrially relevant for the development of biosensors, preventing food oxidation, removing hydrogen peroxide from residual water, and the intensification of oxidase‐driven biotransformations . In a pioneering attempt to expand the applications of CAT, our group has recently exploited CAT in solution to produce bubbles upon H 2 O 2 disproportionation as a source of mechanical energy, which is then harvested by coupling to piezoelectric materials to generate electricity .…”

There is a current need to fabricate new biobased functional materials. Bottom‐up approaches to assemble simple molecular units have shown promise for biomaterial fabrication due to their tunability and versatility for the incorporation of functionalities. Herein, the fabrication of catalytic protein thin films by the entrapment of catalase into protein films composed of a scaffolding protein is demonstrated. Extensive structural and functional characterization of the films provide evidence of the structural integrity, order, stability, catalytic activity, and reusability of the biocatalytic materials. Finally, these functional biomaterials are coupled with piezoelectric disks to fabricate a second generation of bio‐inorganic generators. These devices are capable of producing electricity from renewable fuels through catalase‐driven gas production that mechanically stimulates the piezoelectric material.
