Granola does not go bad quickly. Even under worst conditions – when it has been stored in open jars in a humid and temperate climate – granola will remain good to eat for many days. Some manufacturers sell granola with a shelf life of six months. If their granola can stay fit to consume for six months, it is safe to assume that homemade granola kept under good conditions too can stay edible for this long. So the answer to how long can granola be stored is – it depends. It depends on conditions like humidity, insects, atmospheric impurities, and the ingredients used to make granola. If granola can be protected from all the above mentioned conditions and if the ingredients used to make granola are not easily oxidized, you can store it safely for months.

Commercial methods to store granola

There are several methods to increase the shelf life of granola. Many granola makers trust stand up pouches for this job.

Stand up pouch bags have a multiple layered structure. These layers are chiefly made from plastic. Manufacturers may use layers of aluminum and other metals for additional protection. Together these layers form an effective barrier against all kinds of environmental hazards that can spoil granola. Moisture cannot penetrate the layers of standup pouches, and dust cannot get in. Stand up pouches are flexible yet strong. They are puncture resistant. Therefore they provide sufficient protection against insects trying to bore their way into the mix.

In addition to that, stand up pouches can be made airtight. This feature is especially useful in preventing granola from oxidation. Oxygen is an enemy of food. It reacts with it and makes it rancid. Manufacturers sometimes use oxygen absorbents to make sure that oxygen doesn’t get in contact with food. Other times, they just go for vacuum packaging.

Domestic methods to store granola

Most people who make small quantities of granola at home opt for expensive glass jars and plastic jars to store it. Manufacturers do not use these jars because in addition to being exorbitantly expensive, it is cumbersome to transport and store them. Cost is not a prohibitive factor for people who need to package only small amounts of granola for domestic use. So glass and plastic jars have been ruling this field. But even here, stand up pouches are becoming famous because of their ease of use.

Stand up pouches are travel friendly as they can fit inside the empty spaces in the luggage. They can be hung on walls. They are resealable. And they cost only a fraction of glass and plastic jars. You can't go wrong packaging granola in stand bags!
