The content of hydroxycinnamic acids per serving averages 30% of the adequate level of their daily intake. Polyphenolic compounds are mainly represented by hydroxycinnamic acids, among which synaptic acid and its derivatives and p-coumaroyl chinic acid predominate (45-80% of all hydroxycinnamic acids in total). Pineapple juice is a source of manganese - a portion contains more than 100% of the adequate level of daily consumption of this trace element. The content of vitamin B1 and folate is about 7% of daily recommended level, vitamin B 6 - about 12%. A portion of industrially produced pineapple juice on average contains 10% of the daily human requirement for potassium and magnesium, about 15% for copper, 60-70% for vitamin C. Sugars in pineapple juice are represented by glucose, fructose and sucrose in an average ratio of 1:1:1.6, organic acids are mainly citric and L-malic acids, while the content of citric acid is 2-4 times higher than that of L-malic. The nutrient profile shows the content of more than 30 nutritive and bioactive compounds in pineapple juice. Data analysis of reference books and scientific publications, conducting physic-chemical studies of industrially produced pineapple juice. Aim is to establish the nutrient profile of pineapple juice. Russian Union of Juice Producers together with research organizations is working to systematize and expand knowledge about the composition of juices, as one of the important elements in the structure of human nutrition. Knowledge about food composition is necessary both for specialists to assess the state of nutrition of the population and develop recommendations on nutrition, as well as for consumers to organize healthy individual nutrition.
