How should I store this product to maintain its freshness and nutritional value?

Because this product retains some natural walnut oil and is rich in polyphenols and B-group vitamins, proper storage is essential to prevent rancidity and nutrient degradation. Keep the package in a cool, dry place, shielded from direct sunlight and heat sources. High temperatures and light can accelerate the oxidation of the remaining oils, which would negatively impact both the flavor and the antioxidant activity of the product.

After opening, ensure the container is sealed tightly to minimize exposure to air and humidity. While specific shelf-life details are not provided here, treating it like any other nut-derived product is advisable: if you notice any off-odors or changes in texture, it is best to discard it. For long-term storage, some users prefer refrigerating or freezing opened portions to extend freshness, though this is not strictly required if used within a reasonable timeframe.
