CO2 Extracted Turmeric Oil: A Supercritical Extraction Approach

Introduction

Turmeric oil, extracted from Curcuma longa, is known for its anti-inflammatory, antioxidant, and antimicrobial properties. It is widely used in pharmaceuticals, cosmetics, and food industries. Traditional extraction methods such as steam distillation and solvent extraction often result in lower purity and loss of heat-sensitive compounds.

CO2 supercritical extraction technology (CO2 SUPERCRITICAL EXTRACTION MACHINE) provides an efficient, solvent-free, and high-purity approach to extract turmeric oil while preserving its bioactive components. This article explores the extraction process, key parameters, experimental data, and industrial applications of CO2-extracted turmeric oil.

1. Principles of CO2 Supercritical Extraction

CO2 becomes a supercritical fluid when subjected to high pressure (above 7.38 MPa) and temperature (above 31.1°C). In this state, CO2 has both gas-like diffusivity and liquid-like solubility, making it an excellent extraction solvent.

The CO2 supercritical extraction process follows these steps:...
