What’s the World Series without Peanuts?

Peanut Packaging Nitrogen Generators

Take Me Out to the Ball Game

On October 21st, game one of the 110th World Series kicks off. Throughout its storied history peanuts have been a favorite snack of professional baseball. Dating back to the end of the civil war soldiers from both sides brought their love for the salty legumes to their home town after the interstate scuffle. In 1908 the snack was forever entwined with America’s pastime. That’s the year Jack Norworth penned the lyrics to one of the greatest sports themed ear-worms ever written – “Take Me Out to the Ballgame.”

Most peanuts sold in Major League ballparks are grown in Georgia and North Carolina. Transporting all those peanuts around North America while keeping them fresh can be a challenge. Oxygen and moisture team up with the natural oils in the product to cause spoilage. And no one likes a spoiled legume.

Keeping the crunch – The Science Behind Peanut Packaging

One way to combat spoilage and extend the shelf life of peanuts is to replace some of the moisture and oxygen in the package with a dry, inert gas. This process of changing the atmosphere in the package is called modified atmosphere packaging, or MAP for short.

Nitrogen is the gas of choice for this process as it’s much less expensive than other options. Even so, a medium sized peanut packager can spend 10’s or 100’s of thousands of dollars each year purchasing nitrogen from a gas company, making the process cost prohibitive for some.

A Better Way

There is an option which can help make the MAP process more cost effective. Companies that use nitrogen generators to produce their gas on site pay 50% to 75% less than a delivered supply.

The term nitrogen generator is actually a little misleading. The system, whether it’s based on membrane or pressure swing adsorption technology, doesn’t actually generate anything. Instead, it accepts a supply of compressed air (which is about 78% nitrogen), strips the oxygen, and delivers clean, dry nitrogen. The gas is sent to the packaging line where each bag of peanuts is “flushed” to displace the ambient atmosphere with nitrogen.

Working with an expert

Not every peanut packaging operation is the perfect candidate for a nitrogen generator. When you work with an expert in the field, however, learning whether your situation can benefit from the technology is an easy process. Compressed Gas Technologies has been consulting food packagers for over a decade and can help you quickly determine if a generator is a good fit in your application.


Proof that baseball is nuts

Now that you’re craving the crunch of fresh roasted peanuts, here are some interesting facts to get you ready for this year’s Fall Classic.

The baseball thief

Notorious bank robber John Dillinger played professional baseball before his life of crime. He never made it to the majors but it’s assumed he would have given Ricky Henderson a run at his stolen base record.

Speaking of stolen bases

Herman “Germany” Schaefer is probably the only player to ever have stolen first base. In a 0-0 tie, bottom of the 9th, Schaefer attempted to get the catcher to throw him out as he stole second and free up a runner on third to score. When that didn’t work the shifty Schaefer, known to pull pranks like bringing a lantern on the field to incite the umps to call a game for darkness, then stole first. Eventually Herman tried to steal second back and was tagged out.

The Babe’s peanut salary

Babe Ruth’s top salary was $80,000.00. In today’s money that’s around $1.1 million. In comparison, A-Rod pulled in about 29 times that in 2013. Of his salary, compared to the $75,000 that Herbert Hoover made as President of the United States that same year, Ruth famously said “…I had a better year than he did.”
