Vitamin-mineral isotonic drinks with spirulina in sports nutrition

Aim. The paper is aimed at developing isotonic vitamin and mineral drinks with spirulina, fruits and Siberian berries. Materials and Methods. Spirulina microalgae (Royal Forest, TU 03.21.49-009-29903295-2017) was purchased at the Healthy Food Products specialized store. The physicochemical parameters of spirulina powder were determined in accordance with GOST 31412-2010. The mineral composition of spirulina was studied by atomic emission spectroscopy (AES) using the Thermo Scientific iCaP-6500 DUO spectrometer and the iTEVA software package. The determination of vitamin content was carried out in accordance with GOST and pharmacopoeial standards. Directions for creating isotonic vitamin and mineral drinks with spirulina, fruits and berries were determined based on organoleptic criteria. Results. The mineral composition of spirulina (Royal Forest) was determined, and the content of macro- and microelements in spirulina was correlated with physiological norms for satisfying daily demand of an adult. It is shown that microalgae are a source of iron and copper as the content of these minerals in 100 g of the product reaches 27.9 and 66.3 % of recommended daily intake, respectively. When studying the content of vitamins, it was found that thiamine and riboflavin showed the best indicators of ensuring daily demand of vitamins - 18.5 and 26.3 %, respectively. Based on the assessment of organoleptic properties, the recipes for isotonic vitamin and mineral drinks made of spirulina, fruits and berries are presented. Conclusion. It is shown that isotonic vitamin and mineral fruit and berry drinks with spirulina contain a vitamin-mineral complex and are characterized by increased nutritional and biological value. Such drinks can be recommended for extreme conditions and sports nutrition, including faster and better recovery after heavy physical exertion.
