Use of calcium amino acid chelate in the production of acid-curd goat cheese

Abstract

Amino acid chelates are a new group of compounds approved for food enrichment, however there is no previous research using calcium amino acid chelate to enrich goat s milk products. The purpose of this research was to evaluate the possibility of using calcium amino acid chelate to produce goat s acid-curd cheese. In this study, four types of acid-curd cheeses from goat s milk subjected to 85 °C/5 min treatment were produced: control cheeses made from milk without calcium addition and cheeses from milk enriched with 30, 35 and 40 mg of Ca (in 100 g of milk) in the form of calcium amino acid chelate. Goat cheese with calcium amino acid chelate had a higher moisture content, and a lower fat content. More fat was separated with the whey. In cheeses made from the milk with calcium amino acid chelate there was no goaty taste. Enrichment with 35 mg of Ca in 100 g of goat milk increased the calcium content in cheese by 60.5% in comparison to the control sample. However, the enrichment of goat milk with 40 mg Ca (in 100 g of processed milk) increased the calcium content in cheese by only 63.29%.
