Minimizing Rancidity in Breakfast Cereals: A Comprehensive Review

This report provides a comprehensive overview of rancidity in cereal products, which is primarily caused by the aerial oxidation of unsaturated fats. It explores various techniques to minimize rancidity and improve the shelf-life of breakfast cereals, including the use of antioxidants (natural and synthetic) and different packaging methods (e.g., coextruded polypropylene, HDPE, and metallized polypropylene). The report discusses the synergistic effects of antioxidants and packaging, and examines the impact of processing techniques like flaking and kiln drying. It also addresses the limitations of these techniques, such as the potential loss of heat-liable vitamins and the need for further research on novel compounds and the impact of refined grains and sugar content. The study highlights the importance of cool and dry storage conditions for maintaining cereal quality and preventing rancidity. References to several studies and research papers are included.
