We have developed these services for olive growers and olive oil mills based on our
experience supporting the needs of our customers during the growing and harvest
seasons.
What services do we provide?
For olive growers we provide olive fruit testing to adjust time of harvest and
agronomic practices:
- Olive fruit testing evaluates oil and water content and polyphenols in the
fruit prior to harvest.
For olive oil millers we provide:
- Olive fruit testing: evaluates oil and water content, acidity and
polyphenols in the fruit prior to oil extraction.
- Extraction yield measures the ratio in oil content between olive fruit and
pomace.
- Olive Pomace testing measures oil and moisture content for
downstream uses such as composting or pomace oil extraction.
For millers and producers, to assist in the periodic calibration of near-infrared
(NIR) and other instruments
- Calibration verification provides reference measurements to adjust or
correct instruments reading oil and water content in fruit, and olive oil
quality parameters such as free acidity, peroxide, ultraviolet absorbency
and polyphenols.

How should samples be collected?
- Olive fruit samples should be collected in large zip-loc bags and kept in a cool
container or a refrigerator. About 1 lb of fruit is sufficient. Contact us to discuss a
suitable sampling strategy. .
- Olive pomace (also known as “mash”) samples should be collected in large
zip-loc bags. Use double bags for safety, since water content tends to be high.
About 1 lb is sufficient.
- NIR Instrument calibration samples may consist of olive oil and/or ground olive
fruit paste. It is recommended to submit several samples spanning a range of
result values (high and low), and read all samples on your instrument prior to
shipping for analysis.
- For ground olive fruit, follow the same recommendations above for olive
fruit samples.
- For olive oil samples, submit (at least) 50 ml in a glass container.
