Background:
Extracts from agro-products like spices, herbs, aromatic plants, and medicinal plants are used for various end use applications such as cosmetics, flavours, medicines, perfumes, etc. Presently used extraction methods like Solvent Extraction have number of disadvantages like lower efficiency, lower yield, lower purity of product, longer processing time, etc. In order to overcome these limitations the Super-Critical Fluid Extraction (SCFE) technology has been developed. This development is a joint effort of a team of professionals from different department such as the Department/ Center for Rural Development & Technology, Department of Chemical Engineering and the Department of Mechanical Engineering all from Indian Institute of Technology, New Delhi.

Special Features
Product is superior in quality; Higher Yield; Extracts with delicacy and freshness close to natural; No residual solvent; High potency of active components; Free of biological contaminants Longer shelf life; Ability to fractionate extract in single step; Flexibility to extract multiple products by changing operating conditions; Carbon-di-Oxide as solvent: safe for natural products.

Prospective Users:
Manufacturers of Spice oils and oleoresins; Essential oils: flavors and fragrances; Herbal medicines; Food colours and preservatives Vitamin E (tocopherols); Cholesterol free food products; Decaffeinated coffee and tea; Natural pesticides.
