Awesome . Thanks for the help ! <| sep |> No . Vacuum sealing a fluid milk does not stop it from being absorbed into the coco pops . Your milk will also spoil because the bacteria responsible for that process don ' t need oxygen . If you want to store them for a long time keep them separate and do the flowing 1 . Put the milk in a non transparent air tight container and heat the closed container to 77 degrees Celsius . 1 . Store the coco puffs in a Mylar bag and replace all the air in the bag with a gas that does not contain O 2 like CO 2 or Argon and seal it . If you want to reduce the rate of soggyfication in a coco popmilk suspension you will need to add stuff like antioxidant and acidity regulators to it . But that would most likely make it taste bad and mess with the emulsion balance inside the milk .
