Protein powder is one of those consumable products that has a shelf life. However, it doesn’t rot like perishable foods, but its effectiveness and safety can decrease over time. According to Dr Sarah Brewster, a nutritionist at the London Health Clinic, “To achieve its intended health benefits, protein powder should have the proper quality and nutritional value since these are paramount. For users to know its shelf life is very important.”
There are various factors that influence the shelf life of protein powder. Packaging materials, storage conditions as well as types of proteins used all matter. Dr Martin Hughes, a food scientist says that “protein powders tend to be damaged by moisture and heat too much. It must be kept in a cool dry place.”
Expired protein powder might change texture, taste or smell differently than before. Protein powders can undergo Maillard browning reactions as they get older leading to an off-flavour/staleness according to the Journal of Food Science (2012). “If the powder lumps together or smells strange then it is better to er on the side of caution by throwing it away.” Her words were echoed by Dr Brewster.
Using expired protein powders could lead to health hazards for consumers. Nonetheless, this may result in discomfort in the stomach if consumed despite not being serious food poisoning when taken inside the body system.
Dr Hughes adds, “The degradation of amino acids and potential growth of bacteria in old protein powder can upset the stomach and reduce its nutritional value.” It is known that while protein powders are not always stored properly, adverse reactions are unusual.
To extend the lifespan of protein powder, you should keep it in an airtight container away from light, heat, and moisture. After opening, ensure the container is sealed tightly,” suggests Dr Hughes. To avoid moisture exposure consider using desiccant packs as well.” Furthermore, purchasing protein powder in smaller amounts may help to ensure that it is consumed within its optimal period.
No, it is not recommended to use expired protein powder as the powder can potentially have bacteria and the nutritional value can be degraded.
Protein powder is typically good for 6 to 12 months of the opening date and you should consider the expiry date as well.
To determine if a protein powder is still good, check for changes in texture, smell, and taste. If the powder clumps, has an off-putting odour or tastes stale, it’s likely no longer good.
When protein powder expires, it becomes less effective over time. Accordingly, proper storage and handling are crucial to maintain its quality and usefulness as a supplement. Regularly checking for signs of spoilage and adhering to recommended storage practices can help mitigate health risks. By knowing all these aspects customers will be able to make better-informed decisions with regard to their protein powder usage and where to store it safely.
