Prickly pear in water does not need to avoid light.
Prickly pear is the king of vitamin C in nature, every 100 grams of prickly pear contains 63 calories, including 16.9 grams of carbohydrates, 0.7 grams of protein, 0.1 grams of fat, 4.1 grams of dietary fiber, vitamin C 2585 mg, calcium 68 mg.
Prickly pear’s main calories come from carbohydrates, and its vitamin C content is the highest of any known food, so a small amount will fulfill a day’s vitamin C requirement.
Vitamin C has a spin, but vitamin C does not lose its activity under ultraviolet light, so vitamin C does not need to be stored away from light, which means that you should not drink prickly pear in water away from light.
However, because vitamin C has strong antioxidant properties, long-term exposure to the air is easy to oxidize, thus losing biological utility, so prickly pear water is recommended to drink as soon as possible, so as not to affect its nutritional value.
