Our pistachio kernel oil refined is obtained from the unroasted and peeled pistachios. Our Caloy production unit in Modesto, California is the world's largest producer of refined pistachio kernel oil. Through vertical integration all the way to cultivation, our highly qualified employees ensure consistent quality to meet the ever-increasing demands of the market. Our team of agricultural engineers is in daily contact with the farmers in order to select only the highest quality pistachios when purchasing the raw material. In 2016 our new oil mill with three expeller presses from SKET (made in Germany) was put into operation. The expeller presses were developed and built especially for us to produce nut oils in Germany. The crude oil is obtained by gentle mechanical pressing. We work without additional pressing additives. Thus, we produce 100% high-quality pistachio kernel oil with a gentle process.

After pressing, refining takes place in our own specialty refinery, which was newly built in 2013 and expanded in 2017. Here we neutralize the crude oil with our centrifuge before it is filtered with bleaching earth and activated carbon. The oil is then deodorized at low temperature and a vacuum of about 1 mbar before it is finally cooled down to a temperature of 8° Celsius and filtered again (winterized). Only nut oils are processed in our refinery. A mixing with other products is therefore excluded.

We refine at low temperatures, thus preserving all the important vitamins and naturally contained plant substances contained in the oil.

In addition to high product quality, reliability of supply is also a top priority. Therefore, we maintain large storage capacities in the USA and in various European countries. This enables us to ensure supply anywhere, anytime and just in time. We not only promise security of supply - we can guarantee it.

Our 6-stage system ensures seamless quality control:

1. by our agricultural engineers in the fields
2. by our own Caloy laboratory on receipt of the pistachios
3. after pressing to oil
4. in-process controls at each refining stage
5. final inspection of the oil after completed refining process
6. before delivery to the customer by our Gustav Heess laboratory in Germany, officially accredited according to DIN ISO 17025
