3. The vacuum seal packing removes up to 90% of the air from the package. It's ap-
proximately 21% oxygen in the air, so 90% air removal leaves a 2% to 3% residual
oxygen level in vacuum-sealed foods. When the oxygen level is at or below 5%, as
you know, most microorganisms are inhibited from growth.
4. In general, there have three categories microorganisms: mold, yeast and bacte-
ria, they are present everywhere, but only under certain conditions they can cause
problems.
5. In a low oxygen environment or in the absence of moisture, mold can't grow; In
moisture, Sugar and a moderate temperature circumstance, yeast can grow with or
without air. Refrigeration will slow the growth of yeast and freezing stops it com-
pletely; Bacteria can grow with or without air.
6.
Some dried foods, such as flour and cereals may contain insect larvae, if do not
vacuum-sealed, larvae may hatch during storage and contaminate the foods. To
prevent weevils and other insects from hatching, store these foods in vacuum seal
package is necessary.
7. Avoid spoilage: foods should be stored at low temperatures, for few of the mi-
croorganisms could growth without air.
8. If Temperatures in the refrigerator greater than 40˚F (4˚C) (especially for exten-
ded periods of time), it will support the growth of harmful microorganisms, so we
should keep the temperature at 40˚F (4˚C) or below.
9.
When the temperature for the freezer is 0˚F (-17˚C) or lower, it's suitable for store
foods, although freezing does not kill microorganisms, it retards their growth.
10.
The vacuum-sealed storage temperature will affect dried foods: for their shelf life is
extended 3-4 times for every 18˚F (10˚C) drop in temperature.
