In the complex of effective measures of human organism adaptation for the
environment, as a prophylactic, and therapeutic purposes need adequate intake of bioactive
natural products that can not only provide the body with energy but also compensate the
deficit of essential nutrients correctors of the disturbed link of metabolism. The utmost
importance of products of a functional orientation with the increased interest in non-
traditional fruit crops that had enriched with indispensable bioactive balanced ingredients
with antioxidant, adaptive and detoxifying effect. Natural conditions of Ukraine cause a
strongly pronounced seasonality of consumption of fruit Morus alba L., Aronia mitschurinii
A.K. Skvortsov & Maitul, Hippophae rhamnoides L. Their taste, nutritional value, therapeutic
and prophylactic significance have identified the problem of extending their shelf life for a
year-round diet. The aim of the work was to study the biochemical features of the fruits of the
species and the assessment of the influence of low-temperature technologies on the safety of
their quality indicators.
Used in phytochemical complex conventional methods of chromatographic, spectral and
photocolorimetry, permanganometry, titrimetry, statistics, etc. Freezing fresh fruit (in
packages) – in the low-temperature cupboard: in a quick cold shock (-20°) and long (6
months) cold storage conditions (-10°). This is one of the affordable and effective ways of
preserving the products of the complex of valuable substances when the participation of
oxidative enzymes is blocked and the destructive effect of microorganisms is stopped.
Phytochemical analysis of the fruit indicates a high (8.8 A. mitschurinii, 16.8 M. alba,
10.0–17.5 H. rhamnoides) content (%) monosaccharides, with the advantage of glucose and
fructose, which determine their nutritional value, their level increases after freezing; when
stored for 6 months the smallest losses in the share of sugars were distinguished by the fruits
of M. alba (<1%); to 12.2–19.5 мг% β-carotene in H. rhamnoides and 1.62–2.70 mg% in the
fruits of A. mitschurinii; the presence of organic acids (%): 1.4 (M. alba), 3.0 (A. mitschurinii),
1.8–3.2 (H. rhamnoides) with focus on an apple acid; P-vitamin substances (mg%) is
dominated by (67.9) in the fruits of A. mitschurinii (with high levels of anthocyanins 156.7–
288.0)and significantly accumulate in the fruit superior to the fruits of H. rhamnoides (32.5–
65.0) and of M. alba (35.6–47.8). Fruit are valuable (mg%) with vitamins С: 30.8–110.4 (H.
rhamnoides),15.9–26.4 (A. mitschurinii), 12.8–22.1 (M. alba) and minerals (mg%): for A.
mitschurinii Fe 148.0; К 27.0; Сa 8.0; Na 7.8; for M. alba Ca 5.6; K 15.4; Na 3.8; Si 3.3 and for H.
rhamnoides Fe 43.2; К 21.1; Са 6.5; Mg 2.6. Accumulation (%) of pectins and tannins to A.
mitschurinii, M. alba and H. rhamnoides is 0.7 and 0.6; 0.6 and 0.1 and also 1.1 and 0.9
respectively. t˚shock provoked a reduction of these parameters and vitamin C, however,
during storage, the level of pectin was increased by 1.1 % for all species; vitamin C especially
for M. alba to 25 mg%. Low-temperature technological methods allow maximum
preservation in fruits of high content of native bioactive ingredients with their nutritional and
pharmacological value.
Keywords: Morus alba, Aronia mitschurinii, Hippophae rhamnoides, cold preservation of fruits.
