The most disappointing feeling, that comes in mind, as we tear a bag of Chips or any other snacks to find empty air, with as much as low amount of substance in it.
Well, that extra space in the package is there for a reason. “Slack fill” as it is named, is an intentional choice of snack makers, as to protect these damageable products, from rough handling or from the cramming as placed in the back of a delivery truck. Slack fill helps to act as a cushion that prevents snacks becoming crumbs.
Well, we have many times heard that, the air filled in the packets is not the ordinary gas. Yes, it’s true. It is not the ordinary oxygen gas, it is Nitrogen. The reason of not using the Oxygen gas, as it can lead to potatoes to spoil or the oil to go smelly, and if the air have humidity, it makes the chips go soggy. So, packages are filled with nitrogen gas to help the snacks stay fresh, which a trained panel of tasters confirmed in a 1994 food science study.
Nitrogen isn’t harmful in anyway, as about 78 percent of the air we breathe is composed of nitrogen. Though, this doesn’t excuse the proportion of space that gas occupies in a bag that’s supposed to have food.
Although, all the countries have the Acts, which eventually asks the manufacturers to mention the correct net weigh of the food in the package. But, where companies play with the psychology of the Humans is Humans are terrible at accurately perceiving size, and even the most discerning shoppers will automatically assume that larger packaging means more product if they don’t look too closely at the label. So while some extra space in a bag can help keep potato chips fresh and intact, any more than necessary might be the company trying to pull a fast one over us.
