HTST cooker is a machine using high pressure to sterilize in a short time. We use this machine for various products made in our factory.

Using the know-how that we have acquired in our business with a major CVS chain, we are pursuing safety of all of the our products. In our group company, we can do the chemical test of pesticide, a test of microbe, and a test of radioactivity.

We can analyze soil, chemicals, nutrient, water, radioactivity, and more by using variety analysis machines which are owned by our group company, too.

“Dalat vegetables” are known as good quality vegetables not only in Vietnam but also in Japan.
