[Data] Thermal Stability of Polylysine
Natural amino acid 'Polylysine' as an additive in food preservatives, hygiene materials, and daily necessities. Introducing the thermal stability of polylysine.
ε-Polylysine (hereinafter referred to as Polylysine) is a substance officially known as ε-Poly-L-lysine. It is a homopolymer consisting of 25 to 35 units linked by amide bonds, formed from the ε-amino group of the essential amino acid L-lysine and the α-carboxyl group. Since 1989, it has over 30 years of manufacturing history and is widely used as a preservative in food. We will introduce the effects of heat treatment on the antibacterial effect of Polylysine. The antibacterial effect of Polylysine does not change even after heating at 120°C for 2 hours. Since food is often subjected to heating during processing, Polylysine, which has excellent thermal stability, can be suitably used in heat-requiring foods. *For more details, please download the PDF or feel free to contact us.
basic information
**Characteristics of Polylysine** - Exhibits excellent antibacterial effects against various microorganisms in small amounts. - Shows antibacterial effects over a wide pH range. - Has excellent thermal stability. - Demonstrates synergistic effects when used in combination with chelating agents. - Has a rich track record of use as an additive in cosmetics, hygiene materials, and daily necessities. - Possesses excellent properties as a preservative with high safety. - Highly soluble in water, making it easy to use in food. - Exhibits excellent growth inhibition effects against a wide range of microorganisms, including Gram-positive bacteria (such as Bacillus cereus), Gram-negative bacteria (such as Escherichia coli), and yeasts, particularly those causing food poisoning. - Also shows excellent growth inhibition effects against heat-resistant bacteria, including Bacillus subtilis. - Exhibits strong inhibitory effects against lactic acid bacteria, which significantly affect food spoilage. - High safety has been confirmed through acute toxicity, subacute toxicity, chronic toxicity, mutagenicity, and pharmacokinetic tests in accordance with the guidelines of the Ministry of Health, Labour and Welfare. *For more details, please download the PDF or feel free to contact us.*

Detailed information
-
◎Suitable for mass production - The large crystal discharge outlet after mass filtration processing eliminates concerns about adhesion, accumulation, and clogging of the processed material.
-
◎Improved Crystal Recovery Rate By attaching a nozzle to the scraping device, it is possible to detach residual crystals from the filter cloth using high-pressure air or N2 gas, allowing for the highest efficiency in crystal recovery. Additionally, it facilitates the removal of liquid during reuse. Furthermore, when processing different products, the use of high-pressure water for cleaning the filter cloth enhances efficiency.
-
◎Increase in crystal recovery rate - By making the residual crystal scraping device (patented by our company) a multi-blade structure, it is possible to recover crystals at the highest efficiency up to the limit of the filter cloth.
-
◎Prevention of foreign matter contamination through electric opening and closing The casing opening and closing device can be operated electrically. Unlike hydraulic systems, there is no concern about oil leaks, allowing for manufacturing in a clean environment.
-
By applying a Teflon coating on stainless steel material, it is possible to handle corrosive agents and chemicals.
