Modern supercritical fluid technology for food applications

Area of Science:

• Food Science and Technology
• Chemical Engineering
• Sustainable Processing

Background:

• Supercritical fluid (SCF) technology is increasingly applied to food-based materials.
• Traditional methods often lack efficiency and sustainability.
• There is a need for optimized processing conditions and rationalization of results.

Purpose of the Study:

• To review and update the applications of SCF technology in food processing.
• To advocate for the use of solubility parameter theory (SPT) in optimizing SCF processes.
• To highlight the environmental and biorefinery benefits of SCF technology.

Main Methods:

• Review of existing literature on SCF applications in food science.
• Application of solubility parameter theory (SPT) for process rationalization.
• Comparison of total extraction and fractionation techniques using SCFs.
• Illustration with examples of commercial products and unit processes.

Main Results:

• SCF technology, particularly with carbon dioxide, offers environmentally benign and sustainable processing.
• SPT effectively rationalizes SCF extraction and fractionation of food materials.
• Multiple SCFs and unit processes can be employed for targeted food product development.
• Commercial products demonstrate the viability of SCF media.

Conclusions:

• SCF technology is a key platform for sustainable food processing and biorefineries.
• Further research is needed to expand SCF applications in food science.
• Integration of SCF technology into biorefinery concepts is a significant trend.
