Each of our extracts is produced from medicinal plants collected in the balsamic period.
The specific part of the plant, or itself in full, are used according to
the traditionally recognized health claim on a bibliographical basis and by the Ministry of Health.

In order to guarantee and maintain a high quality standard, all raw materials entering the OTI production departments come from validated suppliers: these are suppliers for whom, through adequate internal organizational and analytical procedures, the reliability in providing to the continuous and timely finding of high quality vegetable specialties has been tested.

The quality parameters of incoming raw materials and outgoing finished products are constantly monitored by the OTI Quality Control Service Laboratories equipped with all the appropriate analytical tools (HPLC, Gas Mass, Atomic Absorption. Spectrophotometer, IR etc…) and all equipment for microbiological controls.

The strength of the production process is the use of the latest generation automatic extractors that allow extraction to be carried out at room temperature (or even lower), thus avoiding the risk of deterioration of thermolabile molecules. This result is obtained thanks to the possibility that our extractors have to work with overpressure and decompression cycles: in fact, while remaining at room temperature, due to the mechanical effect, the molecules are transported from the vegetable matrix to the liquid phase.

The method is standardized, and therefore guarantees the perfect reproducibility of the production process in its completeness. All the plant extracts thus obtained are subjected to adequate analytical checks, carried out by our Quality Control Laboratory. The controls, which are carried out both during the production process and on the finished product, guarantee, in addition to the certainty of the specific characteristics such as the quantity of each extract, the absence of contaminants and pathogenic microorganisms in the product.
