Optimum Extraction

The present study aimed to determine the optimum extraction conditions of conventional solvent extraction (CSE) and microwave-assisted extraction (MAE) techniques to obtain maximum total phenolic (TPC), total flavonoid (TFC), total anthocyanin (TAC) and antioxidant capacity (AA). Response surface methodology (RSM) and central composite design (CCD) were used to determine optimum points of CSE and MAE. Both two extraction methods, all parameters significantly affected TPC, AA, TFC and TAC (p<0.05). MAE showed higher bioactive compounds yield than that of CSE.  Optimum point for CSE and MAE was found to be 60°C and 30 min and 591.83 W and 2.98 min respectively. TPC, AA, TFC and TAC were obtained as 33.81mg/g, 160.27 mg/g, 11.89 mg/g and 331.01 mg/kg for CSE and 62.99 mg/g, 214.62 mg/g, 21.80 mg/g and 3462.93 mg/kg for MAE respectively. This study recommended that the MAE should be used for the extraction of PBL to increase phenolic extraction yield.

Conventional Extraction

In this study, ultrasound-assisted extraction (UAE) was compared with conventional extraction methods, including conventional solvent extraction without agitation (CSE), conventional solvent extraction with agitation at 50 rpm (CSE50) and 150 rpm (CSE150), for the extraction of phenolic compounds from coconut (Cocos nucifera L.) husk. The extraction yield, total phenolic content (TPC) and total flavonoid content (TFC) were examined. The antioxidant capacity of C. nucifera extracts was determined by using 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. Experimental results showed that UAE gave the highest extraction yield, TPC, TFC and antioxidant capacities (ABTS and DPPH), followed by CSE150, CSE50 and CSE, respectively. UAE was found to be more effective than conventional extraction methods. Conventional solvent extraction with higher agitation speed exhibited higher extraction efficiency than those with lower agitation speed and without agitation.

Conventional Solvent Extraction

Agro-industrial waste is a largely untapped natural resource of bioactive compounds including carotenoids and pectin. However, conventional solvent extraction involves the excessive use of organic solvents, costly equipment, and tedious operation. These limitations of conventional extraction methods could be prospectively overcome by the carotenoid–pectin hydrocolloidal complexation. The complexation of lycopene and pectin was efficiently promoted in an aqueous environment, resulting in the colloidal complexes that can be subsequently recovered by sedimentation or centrifugation. In this study, the potential of carotenoid–pectin complexation on tomato pomace containing carotenoids and pectin was evaluated. Tomato pomace is a rich source of lycopene, β-carotene as well as pectin, making it suitable as the raw material for the carotenoid extraction. The extraction of carotenoid and pectin from tomato pomace was optimized using response surface methodology. The maximum recovery was 9.43 mg carotenoid fractions/100 g tomato pomace, while the purity of carotenoid-rich fractions was 92%. The antioxidant capacity of carotenoids extracted from the complexation method was found to be higher than that from the solvent extraction method. Moreover, extraction yield and antioxidant capacity of carotenoid obtained from the carotenoid–pectin complexation were comparable to that from solvent extraction. The carotenoid–pectin complexation is a promising green approach to valorize agro by-products for the extraction of valuable carotenoids.
