Nutritional Value and Safety of Beef for Baby Food

Abstract

AbstractComparative studies of the quality and safety of beef from bulls of the Aberdeen Angus, Kalmyk and Charolais breeds fed up to 18 months under conditions of ecologically safe pasture keeping in the raw zone of beef suppliers for baby and diet food have been carried out. The yield of lean beef from the carcasses of bulls of three breeds was more than 80% with the advantage of the Charolais breed (82.0%). The muscle tissue of the bulls contained more protein (21.7%) and less fat (7.6%). The high protein quality parameter of the longest muscle of Charolais bulls (6.5) indicates a higher (by 2.4 and 1.2%) nutritional value of beef compared to the Aberdeen Angus and Kalmyk breeds. The content of essential amino acids (parameter of biological value) of meat from the carcasses of Charolais bulls was 49.5%, which is significantly higher than that of Aberdeen Angus and Kalmyk bulls, by 1.3 and 2.7%, respectively. Beef from pasture-fed bulls of three beef breeds is ecologically safe and meets the requirements for raw meat for baby food.KeywordsBeef bullsBeefQuality and safety of meat raw materials
