![]() Raspberry has diuretic, choleretic, anti-anemic effect, helps strengthen the walls of blood vessels and promotes intestinal health. Ripe raspberry (Rubus іdaeus L.) contains free organic acids (citric, malic, salicylic), minerals (Co, Cu, K, Na, Fe, Ca, Mg, P), vitamins (B-group, PP, C, provitamin A), tanning substances. Strawberry is rich in phenolic compounds which have antioxidant, anti-inflammatory, and anticancer action. Strawberry (Fragaria x ananassa, D.) is known as a berry with high content of organic acids (citric, malic, quinic, salicylic, as well as succinic and traces of shikimic and glycolic upon ripening), vitamins C, PP, E, B 1, B 2, B 6, B 9, K, carotene, pectin and other substances. So, to level the seasonal nature of consumption, increase the shelf life of the finished product and reduce the transportation and storage costs, they are often processed and dried. However, these are seasonal, perishable products. Adulteration of agricultural raw materials should be regarded as one of the most dangerous types of fraudulent practices, because it creates favorable conditions for unfair competition, leading to stagnation, loss of export potential of domestic food producers and, consequently, to the decrease in the investment appeal of the industry.įresh juicy berries and fruits are natural sources of biologically active substances. In recent years, the spread of adulterated goods there has reached such a level that it threatens Russia’s national security. The modern consumer market of edible raw materials and foods is extremely important strategic part of the modern economy of the Russian Federation. Currently, there are practically no studies aimed at determining quality and chemical composition of fruit and berry powders in order to identify adulteration, though this type of survey would be great practical interest both for producers and consumers. The results obtained allowed to conclude about misinformation and qualitative adulteration of the materials. The “obligatory” amount of K, Fe, Ca, Co, Cu, Mg, Mn were absent in the melon powder, which did not correspond to the fundamental laws of the plant physiology. The raspberry powder was devoid of detectable amount of Co and K, and B, Ca, Cu, Mg, Mn, Si important for plant life were present in residual amounts. The strawberry powder above the detection limit did not contain such essential macro- and microelements as Ca, Mg, B, Co, the amount of Si, Fe, K was at trace level. Thus, the strawberry powder lacked oxalic and tartaric acids, the raspberry raw material lacked malic acid, and the melon material – citric acid. The amount and ratio of organic acids did not correspond to the profile of natural raw materials. This high level of sucrose content indicated the addition of 40.4-52.3% white sugar. In all powder samples the sugars were represented by sucrose in 80-97%. The actual protein and lipids levels did not correspond to the ones declared by the manufacturer in the labeling, and were uncharacteristic of the processed raw materials. It was found that the color and flavor ranges of the studied materials were uncharacteristic of the initial raw materials. We studied organoleptic, physical, chemical parameters, and nutrient composition of strawberry, raspberry, and melon powders and identified their profile of organic acids and mineral composition produced by a Russian company. Adulteration, fruit and berry raw materials, chemical composition of fruits, organic acids profile, mineral elements.
