The duration for which gel ice packs can keep food cold can vary depending on a few factors such as the size and quality of the ice pack, the temperature and insulation of the surrounding environment, and the type and amount of food being stored.
In general, gel ice packs for food can keep food cold for anywhere between 4 à 24 hours.For shorter durations (4 à 8 heures), gel ice packs are often sufficient for keeping perishable items like sandwiches, salads, or drinks cold. Cependant, for longer durations (12 à 24 heures), it is recommended to use a combination of gel ice packs and insulated coolers or containers to ensure the food stays cold.It is important to note that gel ice packs are not as effective as regular ice or ice blocks at maintaining lower temperatures for a prolonged period.
Donc, if you need to keep food cold for more than 24 heures, it is advisable to consider using a different cooling method such as dry ice or frozen water bottles.
Food use gel ice packs are typically made using a mixture of water and a polymer substance, which results in a gel-like consistency. The gel is then sealed in a leak-proof plastic bag. The materials used in gel ice packs are commonly considered safe for contact with food, but it’s crucial to ensure they are specifically labeled as food safe.
Food safety regulations vary across different regions, but manufacturers typically follow guidelines set by authorities such as the FDA (Food and Drug Administration) in the United States. These guidelines govern the materials used in the production of gel ice packs to minimize any potential health risks when used with food.
When purchasing gel ice packs, it’s crucial to look for labels indicating that they are FDA-approved or deemed food safe by relevant authorities in your country. These labels ensure that the gel inside the pack meets specific safety standards and is suitable for use near food products. Always check for proper certification and avoid using gel ice packs that lack such labeling.
