Technical Aspects of Wheat Bran
Wheat bran, derived during the milling process of wheat kernels, provides significant amounts of dietary fiber and various nutrients. Its technical aspects are crucial when considering its shelf life and quality in food products.
Anatomical Composition of Bran
Wheat bran constitutes the outer layer of the wheat kernel, made up of the aleurone, the pericarp, and other several layers that encase the endosperm and germ. This byproduct is particularly rich in dietary fiber, both soluble and insoluble, which contributes to its health benefits. It contains B-vitamins such as niacin, as well as essential minerals like iron, magnesium, and calcium. The composition is also characterized by a higher level of fat compared to other parts of the grain, which can influence the bran's shelf life and the potential for it to become rancid over time.
Chemical Changes in Bran Over Time
Over time, wheat bran's nutritional quality may degrade. Factors include exposure to air, moisture, and elevated temperatures, all of which can lead to the fats within the bran turning rancid, often identifiable by an off-flavor. The degradation rate is influenced by storage conditions; stable, cool, and dry environments can slow the process considerably. Additionally, the expiration date is a guideline for optimal food safety and flavor quality, but wheat bran may be safe to consume past this date if it has been stored correctly and shows no signs of spoilage.
Food Handling and Regulations
When dealing with wheat bran, understanding both food handling regulations and the proper guidelines for use is essential. These standards are designed to promote food safety and prevent health risks due to mishandling or contamination.
