Farklı Kefir Kültürlerinden ve Süt Markalarından Elde Edilen Kefirin Bazı Fiziksel ve Kimyasal Özelliklerinin Karşılaştırılması

Abstract

Abstract
 In this study, three different kefir cultures were using to ferment five different brands of milk samples. pH, the dry matter, ash amount, carbon dioxide (CO2) amount, titratable acidity, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging capacity, the reducing power, the Fe(II) ions chelating capacity, the total phenolic content (TPC), copper(II) ion reductive antioxidant capacity (CUPRAC) and mineral matter contents were investigated in kefir samples and results were evaluated statistically. 
 When kefirs’ CUPRAC, TPC, DPPH free radical scavenging capacity, Mg, Zn and Na concentrations are evaluated in terms of kefir culture, KC1, KC2, KC3, KC1, KC1, and KC1, had the highest values (p
