Soft fresh cheeses, cottage and quarg, are gaining popularity due to the concern for freshness, healthy food and weight control. Unfortunately, these are perishable products with a shelf life of less than 3 weeks, the major factor of product spoilage being surface fungi. This study examined the effect of surface-infrared pasteurization of fresh cottage cheese packed in plastic containers on its microbiological and physicochemical condition during storage. The experimental results show that the surface-pasteurization (5 min, 71 °C) reduced the number of contaminating yeast and molds in a surface layer of ca. 1 cm deep by at least 1 order of magnitude, and may improves the shelf-life at a storage temperature of 4 °C, to approximately 3-4 weeks.
