The revolutionary development of green technology has significantly influenced the recovery of natural compounds for the food industry, with novel extraction methods and the use of green solvents. While green extraction techniques are environmentally friendly and consider health and safety aspects, challenges such as capital investment and running costs are major barriers to their implementation.
The revolutionary development of green technology has markedly influenced the recovery of natural compounds intended for the food industry. Innovation in extraction techniques has been fueled by green chemistry, as well as, the growing public interest for chemical free compounds. Such novel extraction methods include supercritical fluid extraction, pressurized liquid extraction, microwave assisted extraction, ultrasound assisted extraction, cold atmospheric plasma extraction, amongst others. Green technology coupled with the use of green solvents, such as, deep eutectic solvents, and ionic solvents, is regarded as a viable alternative for the recovery natural compound and also prevents the formation of toxic effluents. Apart from the environmentally friendly dimensions of green extraction techniques, the health and safety components are also taken into consideration. Novel extraction techniques are not without their own limitations. As such, the capital investment and running cost associated to these cutting technologies might be major challenges to their implementation and application.
