A comparative study on the antifungal effect of potassium sorbate, chitosan, and nano-chitosan against and in skim milk acid-coagulated (Karish) cheese.

Background And Aim: Yeasts are common contaminants in the cheese industry, which frequently arise from raw milk, the surrounding environment, and equipment, resulting in economic losses in addition to health hazards. This study aimed to compare the antifungal effect of chitosan and nano-chitosan as natural preservatives with a commonly used chemical preservative (potassium sorbate) against and .

Materials And Methods: Laboratory Karish cheese was manufactured with the addition of potassium sorbate, chitosan, nano-chitosan, and their combinations at different concentrations.
