摘要
The use of antimicrobial active compounds (chitosan, lemon and sage extract) in Fior di latte cheesemaking was assessed. The three agents were added at different concentrations during processing cow's milk. Control cheese was also made without active compounds. All cheese samples were kept at 4 degrees C for 7 days and investigated for sensory and microbiological properties. Results clearly showed that the addition of lemon extract and chitosan increased cheese shelf life. In particular, the highest increase (129%) was recorded by adding 1000 mg/kg of lemon. In contrast, the addition of sage extract negatively affected the sensory properties, thus making the cheese unacceptable.
