title: Biofortification of milk and cheese with microelements by dietary feed bio-preparations.
abstract: The present work reports studies on biofortification of milk and cheese with microelements. The diet of goats was supplemented with soya-based preparations with Cu(II), Fe(II), Zn(II) and Mn(II), produced by biosorption, instead of mineral salts. In innovative preparations, soya was the biological carrier of microelements. The utilitarian properties of the new preparations were tested in two groups (8 goats in each): experimental and control. The concentration of supplemented microelements was monitored in milk during the experiment. The collected milk was then used to produce cheese by enzymatic and acidic coagulation method. The effect of milk and cheese biofortification in microelements was confirmed. In milk, the level of the following microelements was higher than in the control: Cu(II) - 8.2 %, Mn(II) - 29.2 %, Zn(II) - 14.6 %. In cheese the content of Zn(II) obtained in enzymatic (19.8 %) and in acidic (120 %) coagulation was higher when compared to the control group. By using bio-preparations with microelements it was possible to produce new generation of functional food biofortified with microelements, by agronomic, and thus sustainable and ethically acceptable way. Biofortified milk and cheese can be used as designer milk to prevent from micronutrient deficiencies. Graphical Abstractᅟ.
