Freeze drying consumables, such as oxygen absorbers, Mylar bags, and replacement oil, play a crucial role in preserving freeze-dried products. Oxygen absorbers help prevent oxidation and spoilage by removing oxygen from the sealed environment, while Mylar bags provide a durable and airtight barrier that protects the contents from moisture, light, and air. Additionally, oil is often used to lubricate freeze-drying equipment or to protect certain food items during the process. Together, these consumables ensure that freeze-dried goods retain their freshness, nutritional value, and long shelf life.
