Dense-Phase Carbon Dioxide Technology

Dense-phase carbon dioxide (DPCD) technology has emerged as a trial blazing technique that is an alternative to conventional food processing methods. Supercritical or dense-phase carbon dioxide (DPCD) is used in this novel technology as a flexible and eco-friendly solvent for a range of food applications. In contrast to traditional methods, DPCD operates under specific pressure and temperature conditions, allowing carbon dioxide (CO 2 ) to exhibit both gas and liquid properties, making it an ideal medium for food processing. DPCD technology has diverse applications in food preservation, extraction, and modification processes. The unique properties of DPCD facilitate efficient and selective extraction of bioactive compounds from raw materials, resulting in enhanced product quality and nutritional value. Additionally, the method serves as a potent antimicrobial agent, contributing to extended shelf life and improved safety of food products. Furthermore, DPCD technology offers a sustainable alternative to traditional solvent-based extraction methods by minimising the use of organic solvents and reducing environmental impact. The ability to operate at lower temperatures also preserves the sensory and nutritional attributes of heat-sensitive food components, positioning DPCD as an attractive option for the food industry. The chapter will delve into case studies and recent developments showcasing the successful implementation of DPCD technology in various food sectors, emphasising its potential to revolutionise food processing practices. As the demand for sustainable and innovative solutions in the food industry continues to rise, DPCD stands out as a promising technology that addresses both environmental concerns and the pursuit of high-quality, minimally processed food products.
