During the penetrometric study, the efficiency of the method for determining the strain of displacement in rennet gel obtained by chymosin of microbial and camel origin was studied. Using the standard measuring time of 60 s, the monitoring of penetration in the gel for the time of 30 s was also investigated. This approach is applied in defining the strain of displacement from the 10 to 90 min during the formation of the gel. The results obtained by the penetrometric study of the rennet gel are the basis for modification of the method of determination of the strain of displacement. The serum released from the gel during the penetrometric study affects measurement accuracy. The results obtained for 30 s indicate better stability of the experimenal data, which shortening the time for its implementation. The information obtained by the conducted study suggests new modification of the method related to the time of penetration from the 60 to the 30 s.
