Keeping Food At Its Best - Sub-Zero PRO 48 Use & Care Manual

Keeping Food At Its Best

Keeping Food Fresh
Your Sub-Zero unit features our unique dual compressor
refrigeration system to keep food fresher longer. However,
the quality and safety of your food also depends on how
you handle it.
The information in this section gives you the most up-to-
date handling and storage recommendations to help you
keep food at its best. If you have specific questions that
are not addressed here, contact a university, county
extension service or your local utility company.
Most food inevitably deteriorates over time. From the very
beginning until it is consumed, food undergoes changes.
Microorganisms get into food, multiply and cause spoiling.
Enzymes that occur naturally in food continue the ripening
process even after the food is harvested. Improper
temperatures cause food to deteriorate faster. Changes
in humidity cause wilting and shriveling that can lead to
spoiling.
Sub-Zero's dual refrigeration system is specifically
designed to combat these changes and keep your food
fresh longer. The individual refrigerator and freezer
systems have been designed to maintain accurate,
consistent temperatures and proper humidity levels for
longer food life expectancy. Dual refrigeration eliminates
transfer of fresh food odors to frozen food or ice and does
not freeze the moisture out of the air in the fresh food
section.
In addition, good handling practices can minimize the rate
of changes in food.
HANDLING RECOMMENDATIONS
• Follow the recommended storage times and tempera-
tures in this guide. Your Sub-Zero unit helps to slow
the ripening process by tailoring temperatures to each
section as needed.
• Use specially designed compartments for dairy foods,
deli foods and fresh produce. These compartments
maintain temperature and humidity levels that keep
specific food groups fresh.
• Rotate food in refrigeration units, using a first-in,
first-out system.
• When food does spoil, it's usually obvious. It becomes
moldy, has an off-odor and looks rotten. But there are
times when spoiling may not be so apparent. If you
think a food has been stored too long, discard it. Do
not taste it to check if it's okay.
