Sports nutrition, like any other product, has a specific shelf life.
After this period, it is not recommended to take the supplement. After all, we are dealing with biologically active substances that lose their properties after a certain period.
Today, we will tell you the shelf life of the protein and the rules for its storage is.
Normal shelf life
The shelf life of sealed (in the original packaging) protein powder varies widely.
Depending on the country of the manufacturer and the legislation existing in it, the product lasts from six months to three years.
Most European firms have a maximum shelf life of two years; American firms have three.
There is also a liquid form sold in ready-made form. It must be consumed no later than one month after the date of manufacture.
Rules of storage at home
Inexperienced “users” often do not realize how much protein can be inconsistent in storage, even if the packaging is not printed.
After all, the protein is sensitive to several physical influences. And they, in turn, can adversely affect the properties of the product.
The protein is afraid of high temperatures.
When the protein is heated to 70 ° C, its denaturation occurs – the destruction of the molecular structure. Then the additive loses its biological properties.
Therefore, diluting protein powder with a hot liquid (water or milk) is strictly forbidden.
As for storage at home, the sealed pack is placed in a cool, dry place, away from household heat sources – a battery or a kitchen stove.
It is also not recommended to store protein on the windowsill to avoid direct sunlight.
After opening the package, in addition to observing the temperature regime, several factors are added:
- Close the package tightly
So you will minimize the penetration into the air. Reacting with it, the powder is gradually oxidized.
- Avoid moisture
Protein does not like high humidity and direct water ingress since in a humid environment, bacteria that lead to spoilage of the product quickly multiply.
The shelf life of The protein of European production after opening is 2-3 weeks, American – 3-4 weeks.
The additive should be stored in a dry, dark and cool place. Be sure to be tightly closed. The optimal temperature is from +5 to +25 ° C.
How much is the finished protein shake saved?
Another pressing question is how much-diluted protein can be stored.
At room temperature, the cocktail is stored for 2-3 hours. In summer, in hot weather – no more than an hour, the refrigerator – up to 5 hours.
If a protein shake is “overstayed”, it begins to lose its nutritional properties. And that’s the minimum. And as a maximum – you can get food poisoning.
To prevent this from happening, there are two options for resolving the issue:
- Carry protein powder, shaker and liquid (water, milk)
When it’s time to make a shake, the protein is kneaded in a shaker.
- An option for the lazy is a ready-made liquid protein in bottles.
It is designed for a single portion. True, for convenience and comfort, you have to pay a higher price.
Taking expired protein
It is believed that protein that has expired and is in its original unopened packaging can be taken for another 6-12 months.
There are many ads for the sale of expired protein on the network, with a pleasant price for such a product.
That’s just a guarantee that the supplement has preserved all the nutrients no one will give. Therefore, to accept it or not is up to you.
Indicators that the additive is spoiled
If the protein is completely spoiled, you will immediately understand it. Such a product has an unpleasant smell and taste. And no one will even think to drink this “rattling cocktail”.
Another thing is when the process of damage has just begun. In this case, it is challenging to catch deviations in the typical smell and taste. After all, due to various flavours and flavour fillers, the signs of spoiled protein are drowned out.
The consequence of taking such a cocktail may be symptoms of food poisoning:
- nausea and vomiting
- abdominal pain
Therefore, if you have doubts about protein quality or shelf life, it is better not to risk and refuse to use it.
Knowing how much protein is stored, in what conditions, and what are the first signs of its spoilage, you will save yourself from wasting money and negative consequences from taking an unsuitable product.
