third-party evaluation

According to analysis of food ingredients at the Japan Food Analysis Center, Inc.
We received very good results for flavor components and health maintenance functions.

The results were well below the standard values for "nitrate nitrogen*, which has been the subject of strong interest in Europe in recent years.
This result confirms that many of the vegetables produced by Ohira Yasai are foods that support the maintenance of good health.

*Nitrate nitrogen is an oxidized form of ammonium contained in fertilizers and rainwater, and is considered a first class carcinogen.
