Sufficient consumption of natural biologically active substances (BAS) – vitamins, dietary fiber, mineral compounds – reduces the risk of developing diseases associated with negative external factors. A large number of BAS are contained in the cherry plum fruits. Cherry plum is characterized by storage short term, during which quality changes are possible. Studies have been conducted on the low temperatures effect the change of BAS in cherry plum fruits. Studied objects were five cherry plum varieties grown in the Russian southern regions – Dinnaya, Zhemchuzhina, Obilnaya, Puteshestvennitsa, Neberdzhayskaya ranyaya. It was found that during storage, the physical and chemical parameters change slightly, the dry substances content decreases (within 1.3-3.2 %), sugars (5.5-7.0 %), the total acids content increases (2.8 3.3 %). The BAS content slight decrease during storage does not significantly affect the nutritional value of cherry plum fruits. The ascorbic acid reduction is 9.8-17.3 %, the anthocyanins content decreases on average from 16.9 to 19.7 %, the beta-carotene content decreases by 8.7-14.8 %, the reduction level of pectin substances is 15.75-22.2 %. Thus, the freezing method application allows to preserve valuable BAS in cherry plum fruits and use them in the future as a basis for the production of functional food products.

Radical Scavenging Properties

The main objective of the present study was to investigate the nutraceutical properties of the bioactive components from the extracts of Canthium parviflorum seeds (CPS). The anti-oxidant property of CPS extracts was carried out by estimating the total phenolic, flavonoid contents, flavonols, flavonols and radical scavenging properties. The results of these findings show that the aqueous extract of CPS rich in polyphenols (87.5 ± 0.2 mg GAE /g) and flavonoids (50.1 ± 0.2 mg QE/g) compounds than organic extracts. The effective inhibitory activity of CPS against α- amylase and α- glucosidases enzyme related to type- 2 diabetes was evaluated and compared. The aqueous extract was exhibited the maximum α-amylase and β-glucosidase inhibition of 91.1 ± 0.4 and 90.5 ± 0.1 % respectively. The seed extracts show a maximum of 25.5 % of protein and 6.4 mg/100g of zinc. The seed extract was exhibited maximum anti-oxidant property with beta carotene content of 5.4 mg/100 g of seed. The present work may be the platform to use to develop high-value nutritional compounds by unutilized plant materials. The natural anti-oxidant and polyphenols present in the extracts were showed great nutraceutical value, and it may be used to develop nutraceutical to enhance a healthy diet.

Human serum retinol and livestock milk retinol levels were assessed as part of a study on the health status of Chadian nomadic pastoralists and their livestock in close partnership between Chadian public health and livestock institutions. Of the examined women (n = 99), 43% were moderately retinol-deficient (0.35 mol/L < × < 0.7 mol/L 95% CI; 33–54%), and 17% severely retinol-deficient (< 0.35 mol/L 95% CI; 10–26 %). None of the interviewed women (n = 87) reported the consumption of fruit, and only two of fresh vegetables were reported consumed in the past 24 hours. Milk is the almost exclusive source of vitamin A for these populations. Goats (n = 6) had the highest average milk retinol level (329 ± 84 mug/kg [mean ± SEM]), followed by cattle (n = 25; 247 ± 32 mug/kg), and camels (n = 12; 120 ± 18 mug/kg). Milk retinol levels did not differ between the rainy and dry seasons. Human serum retinol depends significantly on livestock milk retinol levels (partial slope 0.23; 95% CI: 0.008–0.47). Our study supports the use of goat and cow milk as an important source of vitamin A in pastoral nomadic settings. However, the levels still require to be complemented further by promoting green leafy vegetables, fruits, and supplements.
