Food Grade vs. Industrial Grade: Do The Differences Matter?

There’s this basic idea that industrial-grade and food-grade tanks are the same thing, and that it doesn’t matter which one you use. This is not true at all. Grade labels exist for a reason, so of course there is a reason why it would matter.

Industrial-grade is meant mostly for general use. Factories, construction sites, supermarkets, and entertainment studios use this grade for a variety of purposes (the latter of which we kinda appeal to). Food-grade is meant for exactly what it says it’s for: food (and drinks too). That’s about as simple as you can get. But it is very important that chefs and restaurants use a food-grade tank and not and industrial one.

What’s the Big Deal?

So we already focused a bit on what the basic difference between Industrial and food-grade tanks are, but what exactly makes it suitable for different industries? Simple: the impurities. They are contaminants that are inserted in the tank along with the gas itself, and they usually consist of 1% oxygen, hydrocarbons, benzene, acetaldehyde, or ethylene to name a few. The other 99% of it would be the gas you paid money for, whether its industrial-grade propane, food-grade CO2, whatever. They help add to what makes each gas tank suitable for their intended application.

Contaminants will affect how pure the gas is. Gas tanks have to have a certain level of purity in order for them to be allowed anywhere in the work field. There is a grading system that industrial gas cylinders go through that will determine its purity level. Usually, industrial gases are required to earn at least a 99% purity rating. Some require a stricter 99.9% score. Food-grade cylinders especially need this score to be deemed viable for food prep, and guess who rates its purity level? If you guessed the FDA, you’d be right.

How Dangerous is it Using the Wrong Grade?
