Sweet potato casserole, a beloved Thanksgiving staple, poses a culinary question that has puzzled generations: does it require refrigeration? To answer this enigmatic query, let’s delve into the science behind food preservation and explore the unique characteristics of this savory dish.
The Science of Food Spoilage
Food spoilage is primarily driven by the growth of microorganisms, such as bacteria and mold. These microbes thrive in warm, moist environments and can rapidly multiply, leading to the deterioration of food. Refrigeration slows down this process by reducing microbial growth, extending the shelf life of perishable items.
