The carotenoid extraction yield and the antioxidant capacity extraction yield were 271 mg/100 g DW and 737 μm TE/100 g DW, respectively. Thus, the extraction using ethyl acetate with the ratio of 80:1 (mL solvent per g Gac peel) for 150 min at 40.7°C is suggested for recovering carotenoids and antioxidant capacity from Gac peel.]]> Wed 04 Sep 2019 09:54:30 AEST ]]> Effects of four different drying methods on the carotenoid composition and antioxidant capacity of dried Gac peel https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33074 Momordica cochinchinensis Spreng.) is a rich source of carotenoids for the manufacture of powder, oil and capsules for food, cosmetic and pharmaceutical uses. Currently, only the aril of the Gac fruit is processed and the peel, similar to the other components, is discarded, although it contains high level of carotenoids, which could be extracted for commercial use. In the present study, four different drying methods (hot‐air, vacuum, heat pump and freeze drying), different temperatures and drying times were investigated for producing dried Gac peel suitable for carotenoid extraction. Results: The drying methods and drying temperatures significantly affected the drying time, carotenoid content and antioxidant capacity of the dried Gac peel. Among the investigated drying methods, hot‐air drying at 80°C and vacuum drying at 50°C produced dried Gac peel that exhibited the highest retention of carotenoids and the strongest antioxidant capacity. Conclusion: Hot‐air drying at 80°C and vacuum drying at 50°C are recommended for the drying of Gac peel.]]> Tue 03 Sep 2019 18:30:56 AEST ]]> Encapsulation of carotenoid-rich oil from Gac peel: optimisation of the encapsulating process using a spray drier and the storage stability of encapsulated powder https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35145 Thu 17 Jun 2021 14:49:11 AEST ]]> Yield of carotenoids, phenolic compounds and antioxidant capacity of extracts from Gac peel as affected by different solvents and extraction conditions https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33079 Fri 24 Aug 2018 15:01:54 AEST ]]>
