For your tasty life with our rich & safer products

OKUNO was the first company in Japan to domestically produce baking powder in 1922.
Since then, we have expanded our products in various food additives, shelf life improvers, preservatives,
food quality improvers as well as the sanitary items related to food industries.

As dietary habits evolve, there is a constant demand for processed foods that are both convenient and delicious.
We address this demand by developing, manufacturing, and selling a wide range of products.
Our product encompasses various food categories, including confectionery, noodles, and ready meals.
Notably, we hold a significant share in shelf life improvers and preservative markets domestically, contributing to the prolonged shelf life of processed food.

In our pursuit of superior taste, we also supply many products for processed meat and seafood, frozen foods and highly functional food ingredients.
Furthermore, we provide various methods to control microorganisms such as food spoilage bacteria to support our customers in their product developments.

Additionally, we have developed unique modifying technology on wheat protein as PROFECT series. OKUNO has a wide product range about food quality improvers by the combination of wheat protein with various food materials such as polysaccharides, fats, oil, reducing sugar.
Our quality improvers contribute to keeping food colors, reducing out-of-specification and irregular food product, and increase workability.

It is said that three factors, food-side (like food taste, aroma, texture), human-side (like hungry feeling, emotions, eating habits) and environmental-side factors (like weather, culture), will affect the deliciousness of food.
