The properties of kashar cheese produced with added rennet casein

Abstract

Aim: It was aimed to investigate the changes in the chemical, microbiological and sensory properties of kashar cheese produced by adding different rates of rennet casein during ripening. Materials and Methods: Bovine milk (3,0% fat) was heated (37˚C), enzyme was added. After clotting, pressure and fermantation, emulsifying salts (0,1%), salt (1,5%) and rennet casein (%0-control, 0,5, 1,0, 1,5, 2,0) was added. Produced cheese at melting tank (65˚C, 5 min) was packaged and was ripened (8˚C, 90 days). In samples, dry matter was conducted with gravimetric, fat with Gerber, salt with Mohr and titration acidity with % lactic acidity. Total mesophilic aerobic bacteria, lactic acid bacteria, S.aureus, coliform bacteria, yeast-mould contents of the samples were examined. Sensory evaluation was performed by 7 panelists. One-way Anova test and Kruskal-Wallis H test was used for istatistically analysis. Results: Cheeses were ripened at 8˚C and were analyzed during the ripening period (90 days). pH value was found between 5,62-5,76, acidity 0,55-0,83L.a., drymatter 54,93-58,04%, salt 1,22-1,37%, salt in drymatter 2,21-2,45%, fat 23,67-25,33% and fat in drymatter 41,20-45,46%. Mean values were determined to TAMB 5,17-5,75 logcfu/g, LAB 5,49-6,98 logcfu/g, mould- yeast 3,66-4,88 logcfu/g. There was a significant difference (p 0,05) was found on other criteria. Total scores were between 20,62-22,19 point at sensory evaluation. In the sensory analysis, 3rd group cheese in terms of external appearance and 2nd group cheese in terms of internal appearance statistically have significant difference (p Conclusion: In the production of kashar cheese, it can be stated that production can be made and ripening can be achieved by adding rennet casein.
