Is the gas inside still "food grade," and is it safe for this application? Yes, the gas is food-grade nitrous oxide. The key distinction is the added flavoring agent, which must also be approved for food use. Reputable brands like Rotass use flavorings that are: Food-Safe: Compliant with food regulations in their target markets. Compatible: Formulated not to clog the valve or cylinder. Consistent: Designed to provide a uniform flavor profile. Important: Always ensure you are sourcing from a trusted supplier to guarantee the quality and safety of both the gas and the flavoring agents used. https://www.rotasswhip.com/640g-steel-strawberry-n2o-cylinder
