The Camembert-type cheese was produced from milk in which complex between casein and whey protein is formed by heating at 87°C during 10 min. After cooling to 40°C, 0.35% yogurt culture, 400 mg/l CaCl₂, suspension of Penicillium candidum culture and rennet were added to milk. Cheese ripening occurred during 20 days in ripening room at 10°C and humidity of 90-95%. The yield of cheese increased because of great total nitrogen matter utilisation due to the formation of co-aggregates, namely nitrogen matter content of whey was 0.0651%, which is significantly less related to traditional manufacturing. The deepest changes during ripening were observed in milk proteins, as indicated by high value of ripening coefficient (maturity index). At the end of 20 days' ripening, the soluble nitrogen content was 83.97%, i.e. it was 8.76-fold greater than at the beginning of ripening. The pH of cheese showed permanent increase, it arose from 4.02 to 5.82 during investigated ripening period. Titratable acidity decreased during the first ripening stage (1-10 days), from 237.73T to 146.18°T, due to protein breakdown induced by proteolytic system of Penicillium candidum and lactic acid neutralization. At the second stage of ripening, titratable acidy increased to 190.13°T at the end of ripening period. The sensory characteristics of cheese (aroma, flavour and texture) were characteristic of this cheese type.
