A.
Rinsing
B.
Washing
C.
Sanitizing
D.
Sterilizing
The Answer Is:
A
This question includes an explanation.
Explanation:
The three-compartment sink is the standard for manual warewashing in a professional kitchen, and its effectiveness depends on following the correct sequence of steps. According to ServSafe and the FDA Food Code, the five-step process is: (1) Scrape/Pre-rinse, (2) Wash, (3)Rinse, (4) Sanitize, and (5) Air-dry. Thesecond compartmentis dedicated exclusively torinsing. After items are washed in the first compartment with detergent and hot water ($110^{\circ}F$), they must be moved to the second sink to remove all traces of food particles and, more importantly, detergent residue.
Rinsing is a critical "bridge" step. If detergent is not completely rinsed off, it can neutralize the chemical sanitizer in the third compartment, rendering the sanitizing step ineffective. The water in the rinse sink should be clean and changed frequently to prevent the buildup of "suds" or cloudiness. The FDA Food Code requires the rinse water to be at least $110^{\circ}F$ ($43^{\circ}C$) if used for hot-water sanitizing systems, though clean warm water is the general standard. Sterilizing (Option D) is a higher level of pathogen destruction typically used in medical settings and is not a standard kitchen procedure. By strictly separating the wash, rinse, and sanitize functions into three distinct basins, the operation ensures that each chemical and physical process can function at its maximum effectiveness, protecting the health of the customers.
