Abstract:
1. A process of reducing the agricultural residue (AR) content of a cold-pressed citrus oil, comprising: (a) vacuum batch-distilling an AR-containing cold-pressed citrus oil to give a low-AR distillate and a high-AR residue, wherein the terms “low-AR” and “high-AR” are relative with respect to the proportion of ARs present in untreated cold-pressed citrus oil; (b) subjecting the high-AR residue from (a) to single-stage vacuum distillation, to give a high-AR distillate and a low-AR residue; (c) subjecting the high-AR distillate from (b) to a further batch distillation to give a redistilled low-AR distillate and a waste high-AR redistilled residue; and (d) combining the low-AR distillate of (a), the low-AR residue of (b) and the redistilled low-AR distillate of (c) to give a reconstituted low-AR citrus oil containing citrus elements excluded by conventional distillation.
