BOTTLING / FILLING PETplanet Insider Vol. 25 No. 09/24 www.petpla.net 25 BOTTLING / FILLING 25 Sterile water was produced by non-heat sterilisation using medium-pressure UV lamps and sterilisation filters. These were mixed in the aseptic blender and filled aseptically by filler. More than 10,000 media-filled bottles were incubated per test. After one week of incubation at 30°C, all bottles were visually inspected to ensure there were no spoilt bottles. This media fill test was carried out three times, and afterwards, all tests confirmed zero spoilage. These test results confirmed the confidence in Green Aseptic and allowed production to start, as planned, on April 1, 2024. Creating future standards The history of aseptic packaging began in the 1960s. The technology fills heat-sterilised products into sterilised packs in an aseptic environment. Products that cannot be heat sterilised are filtered and sterilised using a 0.2μm sterilisation filter. However, 0.2μm sterilisation filters have been reported to allow ultra-small and filterable bacteria to pass through. DNP tested the UV resistance of these bacteria and found UV irradiation conditions that kill UV-resistant filterable bacteria at 12Log or more. By combining medium-pressure UV lamps with 0.1μm sterilisation filters, DNP successfully produced sterile water with the same level of sterility as conventional heat sterilisation without heating. This patented technology has enabled significant decarbonisation and energy savings in liquid processing equipment for low and high-acid beverages. DNP is committed to using its long-established aseptic technology to solve today’s societal challenges and contribute to the realisation of a sustainable society. www.dnp.co.jp/eng/group/aseptic-systems MP-UV lamps and sterilisation filters Aseptic filler ?
