The company directly verifies the reliability of its suppliers by permanently performing audit checks. Furthermore, it applies the necessary protections to safeguard the company itself and to offer its customers a healthy and genuine product that complies with the most restrictive European standards concerning extra virgin and vegetable oils. Raw materials are purchased only from the certified suppliers that hold a long-term business relationship with Santagata. In order to be approved by the company, each and every lot of oil is first tested by the internal Panel for a sensory analysis. Furthermore a certain amount of oil is sent to the laboratory of the Consortium the Santagata company is part of for further tests, and only when the resulting chemical and physical parameters meet the required standards the oil is finally unloaded from the tanker truck.

For each oil sample tested, there are tens of chemical and physical parameters that are taken into account and analysed, and they fall into two main categories, the quality and the purity parameters. The meticulous research that is carried out aims at revealing potential frauds or sophistications of the product that could not be revealed only through tasting.
