ОПТИМИЗАЦИЯ МИКРОЭЛЕМЕНТНОГО СОСТАВА ПОЛИКОМПОНЕНТНЫХ РЫБОРАСТИТЕЛЬНЫХ ПРОДУКТОВ ПИТАНИЯ

Abstract

The article analyzes the possibility of increasing food value of fish and vegetable products due to application of non-traditional fish and vegetable raw material and optimization of its microelement composition. For the purpose of efficient modelling formulations there has been considered microelement composition of a number of fish species and vegetables widely used in formulation compositions of polycomponent food products, as well as human need (different age groups) in minerals. Choosing components, that best meet the requirements of modelling, was carried out using the data base comprising over 100 components. As a modelling criterion there was taken a complex generalized criterion of optimality, which accommodated simultaneous accounting parameters of all factors making the formulation model - a multiplicative qualimetric model. A system of requirements for microelement composition of a finished product has been developed using a complex optimality criterion, which depends on a physiological need of the organism in microelements. Optimization of microelement composition was carried out by modeling the formulation of a mixture of minced meat of 7 fish species: pondfish (silvercarp (Hypophthalmichthys), grass carp (Ctenopharyngodon idella), carp (Cyprinus carpio)), freshwater fish (pike perch ( Sander ), pike ( Esox lucius )), sea fish (cod ( Gadus morhua ), Alaska Pollack ( Theragra chalcogramma )) and the addition of vegetable components (carrot, onions, girasol, beetroot, sweet pepper, rice, maze grits, chick-pea). As a result of modelling, there were prepared three receipts of fish and vegetable pâtés most corresponding to the prescribed requirements of optimizing microelement composition of polycomponent fish and vegetable products complying with the human needs. Most balanced microelement composition was registered in the formulation including minced meat of silver carp, cod, pike-perch and vegetable components, such as carrot, onions, rice and maze grits. To obtain a balanced food product it is recommended to combine minced meat of fresh water and sea fish, as well as to use chickpea and maze grits containing selenium that is necessary for the normal functioning of immune system.
