Wheat Germ Spoilage: How to Store and Identify Rancidity

Wheat germ is the inner part of the wheat kernel, minus the outer bran. As a concentrated source of minerals, vitamins and protein, wheat germ is very good for the body. However, because it contains oil, it can become rancid and spoil easily.

Storage

• Wheat germ is sold raw and toasted, and you also can buy wheat germ oil. Once opened, store these products in a sealed container in the refrigerator, as heat, light and oxygen hasten rancidity. Keep no longer than three months, says "Better Homes &Gardens."

Identification

• Use your nose to help you identify spoilage. The aroma and flavor of rancidness can be described as acrid-sharp, bitter and stinging.

Consumption

• Never eat spoiled wheat germ because it can make you very ill. Also, rancid foods destroy the body's own supply of vitamins B and E, two of the key nutrients wheat germ supplies your body with when fresh, says "The New York Times."
