Tomato juice nutritional profile
AbstractEvery juice contains a unique set of nutritive and biologically active substances, exhibiting the properties of the named fruit or vegetable. To characterize the nutritional profile of tomato juice, the literature data (including official reference books) and the results of studies of domestic industrially produced tomato juices conducted by the Russian Juice Producers Union (RSPS) and its members have been analyzed and summarized. From the point of view of providing a man with micronutrients and minor biologically active substances, tomato juice is a significant source of antioxidants - carotenoids and vitamin E, as well as several minerals and trace elements. The amount of lycopene in a glass of tomato juice (200-250 ml) completely satisfies or exceeds the recommended daily intake of this carotenoid; the level of β-carotene in the same volume of juice provides about 20% of the recommended daily intake of vitamin A; potassium and copper - 12-15%, magnesium, iron, manganese and phosphorus - about 5%. Tomato juice is a source of dietary fiber, including soluble dietary fiber (pectin). A glass of tomato juice contains about 12% of the recommended daily intake of pectins and about 8% of dietary fiber. Wherein the calorie content of tomato juice is low - an average of 19 kcal/100 ml. The article continues a series of publications on juices nutrient profiles.
