Ceramic fibers, when used in food storage and transportation, can have a significant impact on food quality. They are known for their excellent thermal insulation properties, which can help maintain the temperature of perishable goods, reducing spoilage and extending shelf life. Additionally, ceramic fibers can provide a barrier against moisture, which is crucial in preventing the growth of mold and bacteria, thus preserving the food's freshness and taste. They may also protect against physical damage during transportation by cushioning the food items. However, it's important to ensure that ceramic fibers used in food applications are food-grade and do not leach harmful substances into the food, as this could affect the quality and safety of the food.
