KINKAN (Fortunella Swingle) GROWING IN THE LANKARAN ECONOMIC REGION AND ITS MINERAL COMPOSITION

The paper shows the main characteristics of Fortunella Swingle, growing in the Lankaran
economic region of the Republic of Azerbaijan and its mineral composition. The mass fraction of
ash, depending on the species of kinkan, ranges from 0.52 ± 0.19% (Fortunella margarita) to
0.61 ± 0.09% (Fortunella japonica). The content of individual elements in kinkan fruits,
depending on the type of berries, is, in mg per 100g-1 : Fe - from 1.79±0.08 to 2.18±0.02; Mn -from 0.47 ± 0.01 to 0.65 ± 0.09; Cu- from 0.28 ± 0.01 to 0.46 ± 0.03; Mg - from 35.70 ± 1.43 to
59.23 ± 1.39; K - from 128.74 ± 3.28 to 156.34 ± 4.18; Ca- from 164.23 ± 3.15 to 193.87 ± 3.14;
Р- from 17.75 ± 0.36 to 24.48 ± 0.22. These data show that kinkan fruits are rich in calcium
(Fortunella margarita) and potassium (Fortunella japonica), which is confirmed by the studies of
other authors. The research results indicate that the main indicators of the chemical composition
of the kinkan berry, including the mineral composition, depend on the type of raw material. The
biological and nutritional value of various types of kinkan berries allows us to consider them as an additional source of raw materials for the production of various food products based on them,
including juices, drinks, compotes, jams, etc
