Physicochemical Properties and Consumer Acceptance of Hydroponic Carrots ( Daucus carota ) in an Extended Screening Process 2006-01-2068

This study compared the physicochemical properties and consumer acceptance of seven nutrient film technique (NFT) and eight microporous tube membrane nutrient delivery system (MTMS) grown hydroponic carrots. NFT-grown carrots had moisture contents range from 86.3–92.1% while the MTMS-grown carrots a range of 82.0–92.0%. β-carotene contents for the NFT-carrots ranged between 2,030–9,900 μg/100 g and for the MTMS-carrots between 2,977–10,488 μg/100 g. Royal Chantenay-NFT- and Mignon-MTMS-grown were the lightest in color, whereas, Mignon-NFT, and Little Finger-MTMS were the darkest. Paramex MTMS-grown was the most acceptable cultivar to the consumers. Paramex, Kinko and Mignon have good potential to be considered for further screening.
