Introduction of the preservative polylysine / fermented polyamino acids that contribute to food poisoning prevention.

Polylysine is a polyamino acid used as a food preservative. It contributes to the prevention of foodborne illnesses, which have become a problem in recent years.

ε-Polylysine (hereinafter referred to as Polylysine) is a homopolymer consisting of 25 to 35 units formed by the amine group at the ε-position and the carboxyl group at the α-position of the amino acid L-lysine, linked by amide bonds. It has over 30 years of manufacturing experience and is widely used as a food preservative derived from amino acids. 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 appear to be fresh can experience rapid microbial growth if the conditions are right, so caution is necessary. Even if the appearance is good, contamination by bacteria can progress, posing a risk of food poisoning. In addition to hygiene management during the manufacturing process and proper storage at appropriate temperatures, the effective use of the preservative Polylysine can help ensure food safety more effectively. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a positive image as a natural fermentation product ■ Listed in the existing additive registry as a food preservative ■ A safe domestic product

A natural amino acid polycation polymer that can be used in food preservatives, hygiene materials, and daily necessities. It is a safe material as it is a fermentation product produced by natural microorganisms.

E-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 amino group at the ε position and the carboxyl group at the α position of the essential amino acid L-lysine. Since 1989, it has over 30 years of manufacturing history and is widely used as a food preservative amino acid. As a product of natural microbial fermentation, it can reduce the use of synthetic food preservatives derived from chemical substances. Polylysine is a cationic polymer with a positive charge. It electrically binds to negatively charged microbial cell membranes, inhibiting microbial growth. Polylysine is listed in the existing additive inventory of the Ministry of Health, Labour and Welfare (No. 397). Example of labeling: Preservative (Polylysine). **Features** - Safe natural microbial fermentation product (not derived from genetically modified organisms) - Provides a good image as a natural fermentation product - Listed in the existing additive inventory as a food preservative - Usable in various foods such as bento, side dishes, various processed foods, bakery products, and confectionery - A safe domestic food product *For more details, please download the PDF or feel free to contact us.*

ε-Polylysine (hereafter referred to as Polylysine) is a homopolymer consisting of 25 to 35 linked ε-amino groups of L-lysine, an essential amino acid for humans, and α-carboxyl groups through amide bonds. With over 30 years of manufacturing experience, it is an amino acid-derived preservative widely used as a food preservative, making it applicable in sanitary materials and more. For example, it is expected to reduce synthetic polymers in everyday items closely related to daily life, such as wet wipes, toothpaste, shampoo, and scalp care products. Even in the presence of chelating agents used as antioxidants in cosmetics, various detergents, chemicals, and pharmaceuticals, it exhibits excellent antibacterial properties. Additionally, it is utilized in preventing bacterial contamination during the manufacturing process of food raw materials, removing anionic substances by leveraging the characteristics of cationic polymers, and in applications for electronic materials and semiconductor manufacturing. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a positive image as a natural fermentation product ■ Listed in the existing additive inventory as a food preservative ■ Can be used as an additive in cosmetics, sanitary materials, and daily necessities ■ A safe domestic product ■ A natural cationic polymer

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

A "non-contact switch" that allows you to open and close doors simply by waving your hand, without directly touching the doorknob or switch! By adopting microwave technology, the risk of malfunction due to condensation in environments with temperature differences, such as cold storage warehouses, is significantly reduced. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, hospitals, nursing facilities, and restaurant kitchens. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ Waterproof and dustproof (IP55 design), allowing the main unit to be washed with water (note: the wall surface (back side) is not applicable) ○ LED display and response sound allow for easy confirmation of detection status ○ Two pattern settings for one-shot and latch output are possible ○ The thinnest in the industry! Only 22mm thick! ◎ For more details, please download the catalog or contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
