Canned Products Based on Animal Hearts as Collagen and Ferrum Sources

Abstract

To activate the elastic tissues regeneration, a man needs to receive at least 5 g of such amino acids as proline and oxyproline, which are involved in the process of the body’s own collagen production, with food every day. The source of collagen can be products made from the hearts of farm animals. High temperature influence destroys collagen, and there is an accumulation of low-molecular peptides that are available to the human body. The article presents the results on the development of new types of canned food based on the farm animal hearts and plant raw materials. The animal hearts are high-protein raw materials in terms of protein content. The fat content does not exceed 3.7 ± 0.5 %, which results in a lower energy value compared to muscle tissue. Proteins in animal hearts are balanced in terms of amino acid composition; the content of collagen in them is 4.8–4.5 %, which is significantly higher than its amount in muscle tissue proteins. The researchers developed technology and recipes of canned food based on animal hearts and vegetable raw materials. The mass fraction of hearts in canned food recipes is 60.0–65.0 %. The additional components were beans and vegetables. Developed canned food made on the basis of animal hearts and vegetable raw materials had high organoleptic characteristics: protein content was 10.7–12.6 %; fat – 7.6–9.1 %. 100 g of canned food contains 0.85 ± ± 0.5 g of collagen-forming amino acids, which allows the human body to provide 16.5 ± ± 0.5 % of the daily need for them. Canned food is an additional source of iron (the content of which is 2.9 ± 0.3 g/100 g). A man recommends canned foods based on animal hearts and vegetable raw materials as specialized products for dietary and preventive nutrition of people of older age groups and persons with reduced processes of elastic tissue regeneration.
