Abstract
Nham colour development can be measured by instrument which is alternatively better than used of consumer testing. For this study therefore chroma meter CR-310 was used for Nham colour measurement. Sodium nitrate and/or sodium nitrite were used together with/without nitrate reducing bacteria as experiment units for investigation of Nham color development. It was found that the used of 500 ppm of sodium nitrate and 200 ppm of sodium nitrite with L. plantarum (103 cfu/g), P. cerevisiae (106 cfu/g) and M. varians (103 cfu/3) in the formulation caused significantly the bright red pink colour development with higher rate and better than other samples significantly (P<0.05). The bright red pink colour was that hue a* (12.6549±0.3900 to 15.1042±0.2725) chroma b* (9.2959 ±0.4190 to 9.8717±0.2768) and value L* (53.9161±0.9858 to 56.0426±0.3142).
