Effects of Different Drying Treatments on the Color of Hemerocallis citrina
Hemerocallis citrina was sued as the research object with four drying methods,including freeze-drying,drying,sun dry-ing,and oven drying.The color,browning degree,chlorophyll a,chlorophyll b,and carotenoids of the products with different drying methods were measured and compared.The results showed that the Hemerocallis citrina treated with freeze-drying had the best color and quality,with the highest L*value and b*value 82.01 and 36.59 respectively.The minimum value of a*was 4.80.The browning degree is the lowest,at 0.16 AU/g.The highest content of chlorophyll a was 62.80 mg/g.The highest content of chlorophyll b was 111.65 mg/g.This study provides reference and data for the future drying of Hemerocallis citrina.
