Physical Properties of Direct Acidified Mozzarella Cheese from Ultrafiltered Whole Milk Retentates

Abstract

Retentates from ultrafiltration of pasteurized whole milk at three volume concentration ratios, 1.4:1, 1.7:1 and 2:1. were made into Mozzarella cheese by direct acidification with 10% glacial acetic acid. Excellent melting Mozzarella cheese was attained and increases in cheese yield were related directly to retentate concentration. Yield efficiency, based on casein recovery, was higher in retentate cheese than in controls. Cheese from ultrafiltered whole milk using low concentrated retentates generally showed improved physical properties over that of nonretentate control whole milks. Composition of direct acidified cheese from whole milk retentates when compared with federal standards of identity fitted those of low moisture Mozzarella rather than Mozzarella. © 1986, American Dairy Science Association.
