Abstract: Colour is a visual perception which helps in judging the subjective quality of product. Chlorophyll is a green photosynthetic pigment which helps plants to get energy from light. In present investigation, the effect of traditional (shade and sun) and cabinet drying on chlorophyll content and colour values of fresh lemongrass leaves and its powder were estimated. The fresh lemongrass had 1.7258 mg/g, while shade, sun and cabinet dried lemongrass powder had 0.1994, 0.1567 and 0.1338 mg/g total chlorophyll content. The chlorophyll a was found to be 0.6514 mg/g which was higher than shade (0.1269 mg/g), sun (0.1156 mg/g) and cabinet (0.1006 mg/g) dried lemongrass powder. The chlorophyll b content of fresh leaves, shade, sun and cabinet dried lemongrass powder were 1.0744, 0.0725, 0.0411 and 0.03322 respectively. The carotene content of shade, sun and cabinet dried lemongrass powder were 0.6243, 1.2307 and 1.9366 mg/g which were less compared with fresh leaves (0.7366 mg/g). The colour parameters for L* values were higher for sun drying (54.81) than shade (52.40) and cabinet (52.33) drying. It was found highest a* was observed for cabinet (-5.10) followed by sun (-4.49) and shade (-3.45) drying. The highest b* value was obtained for cabinet (27.82) as compared to sun (26.11) and shade (26.85) dried powder.
