Modeling of fatty acid composition of poultry meat minced half-finished products with modified fats application

Abstract

Meat products are one of basic fat sources in human nutrition. Biological value of fat is determine by PUFA/SFA ratio and omega-6 to omega-3 fatty acids ratio. Biological value of meat half-finished products is low in cause of high polyunsaturated fatty acids intake . With the object to solution of this problem is modified fat application perceptively. Main object of this work was to investigate the ability of using mixed fat examples for production of protein –fat emulsion and following producing of half-finished meat products (especially cutlets). For investigation was taken a two kinds of mixed fats – one(A) including the palm oil (7%) , palm oleine (30%) and rape oil (63%); and second (B) including the palm oil (70%), corn oil (25%) and flax oil (5%).Testing examples was distributed to the depend protein – fat emulsion content (20, 22,5 and 25 %). Protein – fat emulsion includes the dry milk whey, pork skin protein, water and far in ratio as – 1:4:15:5. Formulation of cutlets consist of emulsion, poultry meat, pork fat and hydrated dietary fiber. Using the mathematical modeling method and analysis of stuff fatty acid composition it was estimated the theoretical fatty acid composition of modeling recipes. Calculated biological value of modeling recipes was higher than value of control example. The PUFA/ SFA ratio was in gap of 0,34- 0,49 for modeling recipes and 0,84 for control example, that shows the efficiency of modified, poultry and pork fat combination in formulas of minced half-finished meat products
