Supercritical Fluid Extraction for the Food and Natural Products Industry

Event Date: 15 Oct 2019

Supercritical fluid extraction is a technology that is well suited to preparation of a range of natural product ingredients and is seeing an increase in industrial utilisation in the food, health, and cosmetic sectors. It is a process that enables ‘solvent free’ separation of many oils, resins, flavour, fragrance, and pigments, without exposure to heat or oxygen during processing.

This workshop will provide an introduction to the use of supercritical fluid extraction technology, what applications it is suited to, and what to expect if investing in extraction equipment or supercritical fluid extracted ingredients. The presentations will include examples of successful New Zealand applications of the technology, as well as emerging and potential opportunities.

Callaghan Innovation has a pilot extraction plant installed at The Food Bowl to enable trial products to be developed and the workshop will include a brief tour of the pilot plant and The Food Bowl facilities.
