Rescuing native technology The old Peruvians, our predecessors, belonging to advanced pre-Colombian cultures, really knew the tinctorial utility of their own natural colorants, particularly the cochineal and annatto. |
Our own cochineal source plantations
Ingenious preparations and tinctorial mixtures from these two raw materials were found on frames and old recipients of a hundred of years of antiquity, which confirms the excellent native technology these old Incas were depending on. Thus, Pronex aim is to rescue this millenary knowledge and to combine it with the present technology, using the most advanced facilities, resulting in our state of the art "Pronex-Tech", so appreciated in the world. Pronex -Tech means Producing the purest carmine lake (up to 90%) commercially available Producing the purest carminic acid (99.9%) commercially available Producing the purest norbixin (up to 75%) commercially available Producing stable Bixin oilsuspension with more than 10% of pigment Producing the purest carminic acid stable (up to 50%) commercially available Pronex-Tech allows us to produce all the above products and, if the customer wishes, with less than 0.2% protein content, avoiding non desired reactions in the final application. Research and Development In a changing world, what is good today is not surely good tomorrow, the food industry and the colorants used for it cannot be an exception. The adaptability of our products to changing needs is therefore an imperative. This decisive innovative mission is largely executed by a highly-specialised staff, in touch with the most recent trends.
Quality Control Rigorous analysis for controlling microbiology contamination, heavy metals, solvent residual, etc., are always done in every batch. For this purpose our laboratory is equipped with modern instruments like: |
Gas Chromatography Double beam UV-Vis spectrometer HPLC chromatography Color Quality Control A sophisticate reflectance colorimeter, able to measure colour space, is used to monitor the shade of our colorants, identifying any slight difference, which could be observed by the human eye. A professional team with more than 15 years of experience assures that the shade of our colour products is consistent. Technology
