We’re going to drop a little science to help explain, hope you don’t mind.
To keep your food super fresh in transit, we use special modified atmospheric packaging, which involves modifying the composition of the internal atmosphere of a package (commonly food packages) to improve the shelf life of fresh food by 200% or more compared to packaging in air.
The process lowers the amount of oxygen in order to slow down the growth of aerobic organisms and the speed of oxidation reactions. This process is safe and allows our meals to withstand 60 hours of travel and delivery time without using preservatives. Recycled denim insulation and non-toxic ice packs keep meals cool until they’re added to your fridge.
Just a note: It’s pretty common for your gel packs to arrive partially melted. As long as your meals are cool to the touch, they’re all good.
