? Shelf life usually refers to how lengthy meals retains optimum high quality after manufacturing. Complement producers should not have to incorporate an expiration date on their merchandise ( 5 ). Nevertheless, many firms voluntarily present an expiration or “best by” stamp together with a manufactured date. In these circumstances, it’s as much as the producer to assist the expiration date of their merchandise with information to exhibit it’s not deceptive ( 5 ). Utilizing an accelerated shelf-life take a look at, researchers in a single examine discovered that whey protein powder has a shelf lifetime of greater than 12 months — even as much as 19 months underneath regular storage situations, that are outlined as 70°F (21°C) and 35% humidity ( 6 ). An accelerated shelf-life take a look at is a technique of measuring and estimating the soundness of a product by storing it underneath traumatic situations, akin to excessive temperature and humidity. In one other examine, researchers concluded that whey protein has a shelf lifetime of 9 months when saved at 95°F (35°C) however a minimum of 18 months when saved at room temperature, or 70°F (21°C) with 45–65% humidity ( 7 ). Whether or not the steered shelf lifetime of whey protein applies to different sources of protein stays unknown, however it’s doubtless comparable if they’re saved underneath the identical situations. In both case, most protein powders available on the market include components that improve shelf life, akin to maltodextrin, lecithin, and salt, permitting for a shelf life round 2 years (8, 9 ). abstract Based mostly on the obtainable analysis, whey protein powder has a shelf lifetime of 9–19 months when saved underneath regular situations.

One examine confirmed that the amino acid lysine in whey protein decreased from 5.5% to 4.2% in 12 months when saved at 70°F (21°C) with 45–65% humidity ( 7 ). Nevertheless, the protein powder used on this examine didn’t include any of the components that many merchandise available on the market include to increase their shelf life. It’s additionally doable for protein powder to go dangerous earlier than the listed expiration date, particularly if it’s not saved underneath cool and dry storage situations. For instance, one examine confirmed that when whey protein was saved at 113°F (45°C) for 15 weeks, there was a big improve in oxidation, which led to the manufacturing of assorted compounds that trigger undesirable modifications in style (12). Oxidation — the response of fat with oxygen — will increase with storage time and damages the standard of protein powders. Excessive temperatures are conducive to oxidation, with analysis suggesting that oxidation will increase by 10-fold for each 50°F (10°C) improve ( 13 ). Indicators that protein powder has gone dangerous embrace a rancid odor, bitter style, modifications in coloration, or clumping ( 7 ).
