Supersoluble Oleoresins & Citrus Oils by Short-Path Distillation

Supersoluble oleoresins are one of Lionel Hitchen (Essential Oils) Limited finest product ranges. Supersoluble oleoresins are produced using the specialist process of short-path distillation (also known as molecular distillation or thin-film distillation)
Short-path distillation involves passing the oleoresin in a very thin film over a heated surface under very high vacuum. The volatile components of the oleoresin instantly evaporate off and are then very quickly condensed on a cooled surface and collected. The name short-path distillation refers to the very small distance between the evaporating and condensing surfaces. This 'short-path' avoids any loss of the most desirable flavour components of the oleoresin. The very high vacuum removes the need to use high, damaging temperatures to produce this quality product.
Supersoluble oleoresins are produced from a range of herbs and spices. These products are for customers that require a clean, soluble and very highly concentrated material that has a fresh flavour.
