Apple jam is not just delicious, but also a healthy product. Apple jam promotes the activation of the digestive process. Regarding its vitamin and mineral composition, it should be said that after prolonged exposure to temperature, only 30 percent of useful substances remain. That is, the B vitamins contained in apples, ascorbic acid (vitamin C) and nicotinic acid are strongly destroyed. At the same time, fiber, pectins and beta-carotene are preserved almost completely.
