Abstract: The present invention relates to a process for making low-moisture mozzarella cheese using recent developments in the technical knowledge about the interactions between cultures, coagulants and cheese technology to increase cheese yields and maintain the cheese quality and functionalities. An optimization may lead to a higher pH and higher dry matter of the curd at the whey off step i.e. pH higher than 6.3 and ideally higher than 6.4 and solid non-fact content higher than 18%, without any modification of the curd composition at the stretching step, i.e. pH between 5.0 and 5.3 and more precisely between without any modification of the curd composition at the stretching step, i.e. pH between 5.0 and 5.3 and more precisely between 5.05 and 5.25, Ca/SNF between 1.7% and 2.4% and more precisely between 1.7 and 2.2%, dry matter between 53% and 55% and more precisely between 53.5% and 54.5%. The coagulant has a C/P ratio of at least 25.

Abstract: The invention relates to a method for continuously, semi-continuously or discontinuously treating a substrate (24) consisting in placing said substrate in a bioreactor receiver (1) and in exposing it to the action of a living cell culture (C1) which makes it possible to carry out a reaction (R1) on the substrate (24) and to which a medium is periodically inoculated with the aid of living cells (C2) improving said reaction. Said living cells (C2) are obtainable by selection from a population of dynamic living cells carried out by an automatic selection device (2) which is supplied by the same substrate (24) as the bioreactor receiver (1) and is originally inoculated with the living cells (C1) contained in the bioreactor receiver (1) tank and an operating device.
