I've been eating hemp seeds for many years now and one thing I've noticed when buying large bulk bags, is the great nutty flavor goes away by the time I get to the bottom of the bag. I've always wondered what could be happening to all the amazing nutritional benefits when hemp foods go stale.
Hemp seeds have no artificial preservatives. It's the Omega-3 and Omega-6 essential fatty acids in hemp seeds that can quickly go rancid. The longer hemp food sits, the more likely it can grow bacteria. The vitamin and enzyme content in hemp seeds also tends to decrease overtime once a bag is opened.
Pro Tip: Don't buy hemp seeds in bulk sizes (2 lbs or larger). Hemp seeds may start to go bad before you're finished with the bag. It's best to purchase hemp seed products in smaller amounts by the case to save money and keep your superfood fresh and yummy.
For best and longest freshness, always close the bag or container you're using, and keep it in the refrigerator or freezer. Placing your favorite hemp foods into an airtight container is even better. I have a set of EVAK PREMIUM Airtight Storage Containers that I use for all my hemp seed food products and absolutely love them. You can find them online at Amazon and in retail stores.
Hope my recommendations help keep your hemp foods healthier, fresher, and better tasting.
