We stored our green tea extract capsules in a cool, dark place at approximately 68Β°F (20Β°C) for six months, both opened and unopened. After that period, we examined the capsules for any signs of spoilage. We noted the appearance, looking for discoloration, and found that the capsules retained their original color. We also assessed the smell, and there was no strong odor detected. The texture remained firm without any signs of degradation. To further verify their safety, we heated a sample to 165Β°F (74Β°C) and observed no changes. Ultimately, we discarded any capsules that showed even the slightest hint of questionable quality.
