Curcumin Extraction, Isolation, Quantification and Its Application in Functional Foods: A Review With a Focus on Immune Enhancement Activities and COVID-19

Abstract: An entirely unknown species of coronavirus (COVID-19) outbreak occurred in December 2019. COVID-19 has already affected more than 180 million people causing ~3.91 million deaths globally till the end of June 2021. During this emergency, the food nutraceuticals can be a potential therapeutic candidate. Curcumin is the natural and safe bioactive compound of the turmeric (Curcuma longa L.) plant and is known to possess potent anti-microbial and immuno-modulatory properties. This review paper covers the various ex… Show more

“…The traditional extraction method takes a long time and has a low extraction rate due to the degradation of CUR caused by high temperature. The commonly used modern method is ultrasonic-assisted extraction (UAE) [ 37 ]. Firstly, the turmeric rhizomes of the plants were cleaned, dried and were then ground into fine powder and passed through a sieve (20 mesh) [ 38 ].…”

“…Curcuminoids (curcumin, demethoxycurcumin and bis-demethoxycurcumin) are most responsible for the biological activity of turmeric [ 29 ]. The isolation of curcuminoids from turmeric rhizomes is achieved by applying conventional and modern extraction methods [ 30 ]. Soxhlet extraction [ 31 ] and maceration [ 32 ] are classic extraction methods.…”
