Evaluation of Nutritional Properties and Consumer Acceptance of Hydroponic Carrots (Daucus carota L.) Grown Under Different Light Intensities and CO2 Concentrations 2008-01-2173
This study evaluated three groups of four hydroponic carrots grown in different lighting and CO2 levels. Moisture, β-carotene, ash, color, texture and consumer acceptance were assessed. For Group I, II and III, moisture content ranges were 81.9-92.4%, 81.9-91.2%, 85.4-89.2%, respectively. β-Carotene content ranged from 3295-10486, 3978-14664, and 5802-21360 μg/100 g for Group I, II and III, respectively. Ash ranged from 0.5 to 1.7%. Color L* value range was 53.7-62.2. Consumers moderately liked the color and slightly liked the crunchiness of the carrots tested. Carrots under low light generally had higher moisture content. However, the other measures were variable.
