- Abstract
The purpose of this study was to investigate the impact of processing conditions on carotenoid contents of the domestic pumpkin. Total carotenoid contents in pumpkin (Cucurbita moschata) were analyzed by HPLC, including all-trans beta-carotene, lutein, and zeaxanthin, with the amount of 166.98-292.76 μg/g (dry weight). After high-speed homogenization (10,000 rpm, 5 to 15 min), the amount of total carotenoids increased from 292.76 μg/g (dry weight) to 339.45, 389.04 and 371.08 μg/g (dry weight) with increased time of treatment. The extraction rate can be increased by 15.9 to 32.9%. After treated with a high-pressure homogenizer (300 and 500 bar), the amount of total carotenoids increased to 335.48 and 366.18 μg/g, representing 14.6 to 25.1% increase compared to the untreated samples. Compared to the samples obtained from the traditional drum drying after a steaming method, samples obtained from the process of blanching, micronization and drum drying retained 30-40% more all-trans carotenoids.
