Method of Choice

Evonik is a global leader in applied supercritical carbon dioxide extraction.

Supercritical fluid extraction (SFE) using carbon dioxide (CO2) is the answer to the growing demand for pure and natural substances for applications in the food, beverage, pharmaceuticals, fragrance and cosmetic industries.

SFE is not only the gentlest extraction method for sensitive feedstocks, it also delivers a number of additional, compelling advantages:

  • 100% natural, safe, inexpensive and environmentally responsible solvent

  • Residue-free end-products

  • Selective process control

  • Improved quality and yield

  • Fully scalable process

Besides being the method of choice for applications designed to extract flavors and aromas, CO2-SFE is also gaining momentum in the high-growth sector of plant substances (nutraceuticals, botanicals, food supplements). Here, requirements for naturalness and purity are very high and conventional methods simply aren’t up to the challenge.

Supercritical fluid extraction using CO2 meets the toughest process standards and delivers results, including higher yields—considerations that make CO2-SFE an alternative well worth considering.

Evonik has been working with SFE since 1980, continuously improving on the process and the technology to either optimize existing products or develop completely new, high-quality solutions for various end markets. Here, the combination of extensive know-how and advanced technology translates into shorter turn-around times and tailored solutions—for optimum, cost-effective results that give our customers the edge.
