Have you ever been worried about how to store flour? How to store flour has always been a difficult problem. Flour is easily disturbed by the external environment so as to its quality will be seriously affected. So how to keep the flour for a long time?
How to Tell If Flour Is Fresh?
When it comes to how to store flour, it is inevitable to mention how to judge whether flour is fresh or not. As is known to us all, flour is one of the most critical elements in making baked products. The taste of baked products will greatly depend on the quality of flour. But the bad thing is that we can’t recognize the freshness of flour with the naked eyes, only by identifying the smell of the flour. Fresh flour does not have a distinct smell. Whereas, when it will have a slightly sour and musty smell, it means that it has gone bad.
Can Flour Spoil?
Flour is easily susceptible to external environment. Flour spoilage usually occurs due to the degradation of the oils in the flour, which causes flour to go rancid. Especially when flour is exposed to moisture, heat, light or oxygen, such above elements can also lead to the spoilage of flour. Additionally, bugs infestation, such as weevils, will similarly make flour go bad. Hence, how to avoid flour deterioration, we need to start from the above aspects, one by one to break through. And then a perfect can make all this easier.
The Problem with Paper Flour Bags:
The most common and traditional flour bags are typically made of paper, which are not airtight. That means moisture, light, or oxygen can easily get into the flour. Even more unpleasantly, tiny bugs and pests can be also accessible to the flour products inside. Hence, to protect flour against above terrible factors, one of the best method is to seal flour in the mylar bags wrapped by layers of aluminum foils.
The Benefits of Storing Flour with Mylar Bags:
If you want to store flour for a long time, the best solution is to use sealed mylar bags. Mylar bags are made from food grade material, which is perfect for storing flour and keeping the quality of flour. Wrapped by layers of aluminum foils, the flour bags are impervious to moisture and oxygen, acting as strong barrier against some terrible factors. Sealing flour in mylar bag can nicely create a relative dark and dry environment for flour, thus the flour is completely safe from light, moisture and oxygen. That will reduce the risk of deterioration. Additionally, the mylar is constructed from metalized polyester, impenetrable to moisture, oxygen, light, and also those bugs and weevils.
The Drawbacks of Storing Flour in Paper Bags:
Mold: Humidity or high temperature can cause flour to absorb moisture and eventually start to get moldy. When flour get moldy, it will naturally emit a terrible sour smell.
Oxidation: oxidation occurs when oxygen interacts with nutrients in the flour, causing them to break down. That means oxidation will directly lead to the loss of nutrients in the flour. Besides, oxidation will cause the natural oils to make flour go rancid.
