Abstract:
A study has been made with an objective to prepare moist pet food with retort process technology and to evaluate the Hunter laboratory colour values such as L*, a*, b*, Hue* and Chroma* values on the moist pet foods during storage up to 6 months. Hunter Lab Colour values such as L*, a*, b*, Hue* and Chroma* angle value of the retort packaged moist pet food samples during ambient storage temperature had a significant difference (p<0.05) from one to six months. The L* and a* values of the moist pet food samples packed by retort packaging exhibited a decreasing trend from 1 to 6 months whereas the b* value showed an increasing trend. Similarly, the Hue* angle and Chroma* angle values of the moist pet food samples packed by retort packaging method had an increasing trend till 6 months at ambient temperature.
