Abstract:
The value of L*, a*, b* and darkness factor of fresh carrot puree as well as dried carrot puree were recorded through hunter colorimeter and other chromatic properties i.e. change in brightness (ΔL) value, change in redness (Δa) and change in yellowness (Δb) were calculated. The mean values of L*, a*, b* and darkness factor of fresh carrots puree were found 52.23, 26.12, 42.87 and 1.64 respectively. The significant observation of L* values of dried carrot puree products were found between 43.11 and 55.51. The significantly maximum L* value 55.51 was observed for treatment T7 and significantly minimum L* value 43.11 was observed for treatment T19. The significant observation of a* values were found between 20.22 and 28.69. This means all dried samples indicates red in colour. The significantly maximum a* value 28.69 was observed for treatment T7 and the significantly minimum a* value 20.22 was observed for treatment T19. The significant observation of b* values were found between 36.03 and 44.21. The significantly maximum b* value 44.21 was observed for treatment T7. This means all dried samples indicates yellow in colour. The significantly minimum b* value 36.03 was observed for treatment T19. The significant observation of ΔL values were found between 9.12 and 3.28. The significantly maximum ΔL value 3.28 was observed for treatment T7 and the significantly minimum ΔL value 9.12 was observed for treatment T19. The significant observation of Δa values were found between -5.90 and 2.57. The significantly maximum Δa value 2.57 was observed for treatment T7 and the significantly minimum Δa value -5.90 was observed for treatment T19. The significant observation of Δb values were found between -6.84 and 1.34. The significantly maximum Δb value 1.34 was observed for treatment T7 and the significantly minimum Δb value -6.84 was observed for treatment T19.
