The present invention discloses a substance composed by organic materials, a process for the preparation and uses thereof. The components of this invention are plant extracts. Due to its constituent components, the formula may be a substitute of preservatives or the refrigeration process of milk and the derivatives thereof such as those made from chemical molecules and natural-occurring compounds such as those derived from citrus fruit and the like, which are currently used for maintaining the natural properties of milk and its derivatives that are usually toxic for humans and represent environmental pollutants. The object of the present invention is to provide a substitute for conventional products and eliminate the use of chemical molecules having toxic elements that are currently on the market because, thanks to their naturally-occurring components, said substitute is fully harmless to humans in addition to fulfilling the highest effectiveness characteristics as compared to those c urrently available on the market, but without their harmful effects and at a low production cost. In addition to the above-described benefits, the requirement for cooling the milk after the milking process and transportation thereof to be pasteurized would be eliminated.Esta invención se refiere a una substancia compuesta por materiales orgánicos, su proceso de elaboración y sus usos.
