Process for clarification and enrichment of citrus oil

NOVELTY – Process for clarification and enrichment of citrus oil substantially free of impurities, comprises: introducing citrus oil in a molecular distillator; and obtaining a distillate stream enriched with volatile compounds and a residue stream enriched with non-volatile compounds. USE – The process is useful for clarification and enrichment of citrus oil, which is useful: for application in paint; and as a complement for animal food, and cosmetic industries. ADVANTAGE – The citrus oil is substantially free of impurities comprising water, solvents and/or solids in suspension. The process of clarification and enrichment of citrus oil: does not employ any solvent of any nature using molecular distillation; allows for obtaining the pure product, without the need for a step of cleaning/eliminating the solvent; and does not utilizes high temperatures, thus assuring not to occur thermal degradation or losses of the volatile compounds of interest. The process reduces the processing time to few minutes using molecular distillation with the function of clarification and enrichment of citrus oil, and enables the use of the process for the continuous obtainment of high value added citrus oil. The process is simple. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are included for: distillate stream, residue stream and the citrus oil obtained by means of the process. DESCRIPTION OF DRAWING(S) – The figure shows a centrifugal molecular distillator. Feed and exit temperature controls (20) Feed and exit flow rate control (21) Vacuum control (22) Evaporator temperature control (23) Sample feed vessel. (24)
