[Hypercaloric poultry meat product for enteral nutrition]

Enteral nutrition is considered an important component of nutritional support in all clinical groups of patients. Poultry meat in the human diet is a source of complete protein with high digestibility, a number of minerals, vitamins, trace elements and bioactive compounds. In this regard, the development of an enteral product based on poultry meat intended for probe nutrition and/or oral consumption can be considered an urgent task, allowing to expand the range of foods for special dietary uses. The aim of the work was to develop a formulation and technology for a sterilized hypercaloric enteral formula based on poultry meat and to evaluate its quality and safety.

The object of the research was experimental samples of a sterilized enteral formula based on poultry meat, manufactured according to a formulation developed in accordance with medical and biological requirements. The theoretical calculation of the formulation was carried out using the computer program «System for designing and evaluating the quality of multicomponent food compositions». Standard conventional methods were used to evaluate protein, fat and moisture content and pH. Total amino acid composition was measured by the chromatographic method on an automatic liquid amino acid analyzer, tryptophan and L-glutamic acid level was evaluated by spectrophotometry. Fatty acid composition was assessed by gas chromatography using a column to determine the qualitative and quantitative composition of a mixture of fatty acids in the form of methyl esters. The content of vitamins В1, Е and D was determined by high-performance liquid chromatography, manganese, magnesium, calcium, zinc, iron - by atomic absorption method. Industrial sterility was evaluated in accordance with the requirements for group A canned goods. The stability of the dispersed system was determined using a laboratory centrifuge type Z 206 A (Hermle Labortechnik GmbH, Germany).

In accordance with the medical and biological requirements, a formulation of a hypercaloric enteral formula containing poultry meat and process parameters have been developed to obtain finished product with the required organoleptic characteristics. The resulting product meets the specified requirements for energy content (150 kcal/100 g) and its distribution (16-20% protein; 35% fat; 45-49% carbohydrates), the content of vitamins, minerals, trace elements and bioactive compounds; it has a balanced amino acid and fatty acid composition. According to organoleptic characteristics, the product is a fluid, homogeneous, highly dispersed mass with low viscosity, without delamination of the structure, which allows passage through a tube with an outer diameter of 4.62 mm.

After conducting clinical trials the developed product can be used as the sole or additional source of nutrition for patients with malnutrition.
