A review on instant controlled pressure drop technology – a strategic tool for extraction of bioactive compounds

Abstract

Summary Bioactive compounds are the naturally derived extra‐nutritional components with diversified arrangement and functionality, which makes them a promising source for the fabrication of functional foods, nutraceuticals and food additives. Extraction of these compounds by traditional techniques is a cumbersome process, which yields product with compromised quality and poor efficiency besides huge investment in terms of energy and time. This urges an acute need to develop an improved method that ensures the nutritional and organoleptic quality of these bioactive components is better preserved. Instant controlled pressure drop is one such novel and sustainable technique that allows the raw materials to be treated at high pressure and temperature first and latterly followed by an abrupt pr
