Aqueous Extraction of Curcuminoids from Curcuma longa: Effect of Cell Disintegration Pre-treatment and Extraction Condition

چکیده
Abstract Cell structure modification techniques have the potential to improve curcuminoid recovery in Curcuma longa . In this study, different pre-treatments such as high hydrostatic pressure (HPP, processing), ultrasound (US), pulsed electric field (PEF), and ohmic heating (OH) were used on dried C. before aqueous extraction at pH 2.0, 5.0, 8.0. The released curcuminoids, cell disintegration index (Z p ), particle size distribution (PSD), color (CIE L*, a*, b*) evaluate pre-treatment impacts plant extract properties. untreated turmeric, highest amount of curcuminoids (3.89 mg/g dry matter) was obtained after for 30 min 95° phase. After pre-treatments, acidic conditions showed a considerable improvement recovery; PEF, HPP, OH improved by 3.39-, 3.13-, 1.24-fold, respectively; while US did not lead an increased release compared material. (with PEF 5.0) 6.6% w/w total curcuminoids. non-thermal less impact extract’s pH, with alkaline reducing lightness extract.

متن کاملFormic Acid and Microwave Assisted Extraction of Curcumin from Turmeric (Curcuma longa L.)
Curcumin is a natural bioactive compound originated from the rhizomes of turmeric (Curcuma longa L.). This study was performed to investigate formic acid and microwave assisted extraction of curcumin from turmeric (Curcuma longa L.). In order to enhance the curcumin extraction, different parameters such as particle size, effect of pretreatment with water, radiation intensity and type of solvent...

Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...
