The Effect on Xanthophyll Content and Color of Broiler Skin When Scald Additive Concentration Was Measured by pH ,

Three experiments were used to determine that scald water pH could be altered by changing the concentration of a commercial scald additive without affecting color of the skin. The pH of the scald water which indicated the optimum level of additive for feather removal also retained the most yellow color in the skin. The pH of the scald water must be monitored constantly to maintain an optimum concentration of additive. The temperature of the scald water did not alter the lack of influence scald water pH had on skin color.
