In addition to its other qualities as a flavoring, cinnamon kills microbes. Researchers have taken advantage of that property to develop an anti-mold wrapper.
Even with bread already tainted with mold, wax paper made with 6 percent cinnamon oil inhibited mold growth by 96 percent, prolonging freshness by up to 10 days. Plain wax paper did not slow the mold at all.
The environmentally friendly wrapper may also be effective in keeping fruits, vegetables and meats fresh.
