Nutritional value of carbohydrate-protein product for athletes
Keywords:
carbohydrate-protein product, nutritional value, digestible indispensable amino acid score (DIAAS), mineralsAbstract
Background. The targed cosumer group of the developed carbohydrate-protein food product "Nanoline. Power" [2] is athletes of strength and speed-strength kinds of sport. To improve efficiency of trainings of athletes diet must satisfy energy, macro- and micronutrients requirments, and maintain water-salt balance. The aim of this work is research of nutritional and biological value of the developed product.
Material and methods. Objects of the research are carbohydrate-protein food products for athletes "Nanoline. Power" and control sample of home manufacture "Vansiton. KREAMAS" (DelMas LTD).
The total content of proteins was determined by the Kjeldahl method [3]; mass fraction of fat in the dry matter by the extraction-gravimetric method [4]; total sugar content by the iodometric method [5]; mineral composition by the atomic emission spectroscopy with inductively coupled plasma (AES-ICP) on the Optima 2100DV of Perkin-Elmer (USA) [DSTU ISO 11885:1996]; amino acid composition by ion-exchange chromatography on an automatic amino acid analyzer T 339 ("Mikrotehna", Czech Republic) [6]. The Digestible Indispensable Amino Acid Score (DIAAS) and the Amino Acid Score Difference Coefficient [9] was calculated.
Results. The recommended amount of product satisfies 50–85 % of the daily requirement of protein, 3–6 % of fat, 15–30 % of carbohydrates, depending on the intensity of the training process, physiological needs and individual characteristics of an athlete. Caloric value of the developed carbohydrate-protein product satisfies 20–40 % of daily energy expenditure of an athlete.
Developed carbohydrate-protein product contains 1.6 times more essential amino acids than the control sample.
By enrichment of the "Nanoline. Power" with minerals the high level conformity of the mineral content of the product with daily requirements of athletes is reached. Ratio Р : Са : Mg is 1 : 1.04 : 0.53 and close to the optimal.
Conclusion. The high nutritional and biological value of the developed product "Nanoline. Power" is determined. Using whey protein concentrate enabled to balance the amino acid composition of the protein component of carbohydrate-protein product. By additional introduction of minerals conformity of the mineral content of the product with daily requirements of athletes is reached.
