How Do You Know That Almond Flour Has Gone Bad?

Below are the obvious signs of almond flour gone bad. Let us review them one by one and check for the signs to see if it has gone bad.
1. Change In Aroma
Fresh almonds usually have a nutty smell, which persists even when it is grounded into a powder. A packet of almond flour would emanate this odor. It is a sure-shot sign that it has gone bad if it has lost this smell.
2. Altered Color
Almond flour is not usually ivory or white. They have a light brown or a faded yellow color which is very visible. Almond flour which has been preserved for a long time, should maintain this color. If there is any change in the color, it is better to discard it immediately.
3. Clumps
Almond flour is very vulnerable and prone to getting stuck with moisture. It has to be locked away from external air so that moisture does not intrude. The clumps formed in the flour are indicative of spoiled almond flour. The mold will then start to grow to spoil the whole flour instantly.
4. Grayish Spots
When mold starts growing on the flour, the surface of the flour will develop green or grayish spots. This is an indication that it has become moist and spoiled.
Sometimes it might be developed on the external surface, leaving the inner layers to be free from any damage. In this case, the outer surface can be scraped off or removed, and the rest of the flour can still be used.
5. Insects
Moist flour attracts insect-like bacteria, and that is quite a visible sign to discard it immediately. The insects will feed on the flour and breed on the whole package rendering it completely useless.
How Do You Store Almond Flour?

Storing the almond flour correctly saves it from any eventual damage or breeding of bacteria and insects. Below are some tips which might be useful for you to extend its shelf life.
1. Select A Cool Place
A slightly moderate temperature place without any eventual lighting or heat should be an apt place to store almonds. This will shield the flour from oxidizing, preventing it from becoming rancid and smelly.
2. Keep The Flour In A Sealed Container
The flour has to be preserved in a closed container that is properly sealed without any gaps.
If you have opened it once and cannot completely package it back the same way, you can shift it to another packet and seal it completely. Sometimes a ziplock bag or a plastic bag that is sealed tight could be the way to go.
3. Refrigerate
This is the best way to store almond flour, which can be refrigerated for years together without any issues. You still have to package it in a sealed bag, and there should be no leaks.
This will definitely shield the flour from attracting insects and will also eventually lock out any bacteria that could potentially affect the flour.
