A study was undertaken to examine the effect of oxygen absorbers (by Atco) used in the packaging of white cheeses on their shelf life. White cheeses packed in bags made of PA/PE laminate with and without oxygen absorbents were stored at a temperature of 5±0.5oC for a period of 7, 14 and 21 days. In the time spans mentioned, the white cheeses were determined for: the number of yeast, mould, and coli group bacteria, and for titratable acidity. Oxygen content of white cheese package atmosphere was assayed as well. The application of oxygen absorbers resulted in inhibited growth of yeast and moulds, and after two weeks also the growth of coli group bacteria. The presence of oxygen absorbers was observed not to affect any increase in the titratable acidity of stored white cheeses. The oxygen absorbers were proved effective in the modification of package atmosphere, i.e. they decreased oxygen concentration in the package atmosphere below 0.5%.

The growth of pathogenic microflora was monitored in fresh white cheeses stored for 7, 14 and 21 days at a temperature of 5oC±0.5oC, packed under vacuum, modified atmosphere and air atmosphere conditions. The fresh and stored white cheeses were determined for the numbers of Listeria monocytogens, Enterococcus spp, coli group bacili, and Escherichia coli. The results obtained indicated that the method of packaging had no effect on the development of those microorganisms in white cheeses during their chilled storage.

The aim of the study was to follow up the properties of cheese mass obtained from ewes’ milk depending on the pasteurisation temperature, the kind of starter added and level of calcium chloride addition. The chemical composition, pH and texture of cheese mass produced from raw, pasteurised in 72°C for 15 s, and pasteurised in 95°C for 5 s milks were established. Similarly the cheese mass obtained from pasteurised milk without starter addition, with starter of mesophilic bacteria (Lc. lactis ssp. lactis, Lc. lactis ssp. cremoris, Lc. lacits ssp. diacetilactis) and with thermophilic starter (Str. thermophilus, Lb. delbrueckii ssp. bulgaricus). The same routine was applied to cheese mass obtained from pasteurised milk without CaCl2 addition or with 0.1 g/l, or 0.2 g/l of dehydrated CaCl2 addition.

Ewe's milk non-concentrated and concentrated by ultrafiltration to 60% of initial volume, was processed into soft cheese. The cheese were stored, in 4°C, for 14 days. The milk, retentate and fresh cheese were analyzed and also cheese after 7 and 14 days of storage were estimated. Organoleptic assessment, yield, physico-chemical properties and texture analyses were done in cheese. It was observed that cheese yield made from ultrafiltrated milk was higher than from non-concentrated milk. The fresh cheese made from concentrated milk contained more: water, total nitrogen compounds and free fatty acids and less fat. These cheese were softer and had higher cohesiveness than cheese made form non-concentrated milk. The ultrafiltration enchanced the cheese properties. All cheese were edible after 14 days of storage.
