Introduction of the preservative polylysine / fermented polyamino acids that contribute to food poisoning prevention.
We provide easy-to-understand materials explaining the natural preservative polylysine, which prevents food poisoning. ε-Polylysine (hereafter referred to as polylysine) is an amino acid-derived preservative widely used as a food preservative. By adding polylysine, the growth of microorganisms that cause food poisoning can be prevented. Every year, food poisoning caused by microorganisms is a significant issue and is frequently reported in the news. Even foods that do not appear to be spoiled can rapidly proliferate microorganisms if the growth environment is suitable, so caution is necessary. Even if something looks clean, contamination by bacteria can progress, posing a risk of food poisoning. By ensuring hygiene management during the manufacturing process, proper storage at appropriate temperatures, and the appropriate use of the preservative polylysine, food safety can be more effectively protected. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a good image as a natural fermented product ■ Listed in the existing additive registry as a food preservative ■ A safe domestic product *Please feel free to contact us.

Achieving long-distance wireless Ethernet transmission of up to 1 km using the sub-gigahertz band. New release of Ethernet wireless converters "RP-WAH-SR12/RP-WAH-SR22".
Contec has developed the Ethernet wireless converters "RP-WAH-SR12" and "RP-WAH-SR22," which utilize 920MHz sub-gigahertz wireless (IEEE 802.11ah) to enable Ethernet communication wirelessly even at distances of up to 1 km. Sales began on August 21, 2025. The new products are compact IEEE 802.11ah compliant wireless LAN converters that can be installed in various locations. The new Wi-Fi standard "IEEE 802.11ah," which utilizes sub-gigahertz wireless communication, became available in Japan in September 2022. It operates in the 920MHz band without the need for a license and can be used outdoors. Compared to conventional 920MHz wireless communication, it enables high-speed communication and the establishment of long-distance networks, making it expected to be utilized in large factories, plants, and farms. The new Ethernet wireless converters are designed to be lightweight and compact, allowing for installation in various locations such as walls and DIN rails with the included mounting brackets. Additionally, they support external antennas, enabling the construction of flexible wireless LAN systems.
