Which factor does NOT affect how well a chemical sanitizer works?
a.The temperature of the water in use
b.The color of the sink basin
c.The sanitizer concentration
d.Contact time and soil on the surface
Giải thích
Chemical sanitizers work based on concentration, water temperature, contact time, water hardness and pH, and how clean the surface is; soil on the surface can neutralize the sanitizer. The color of the sink basin has no effect on sanitizing — the other three options are all real variables the Food Code makes managers control. Managers must control those real variables, especially concentration, temperature, and time, to sanitize effectively.
