Paneer was prepared and cut into cubes of three sizes i.e. 1.5, 2.5 and 3.5 cm. Their surfaces were treated with two concentrations (0.8 and 1.2 % w/w basis) of dry common salt. They were packed in LDPE (50-55 micron) packages and stored at 3 different temperatures i.e. 20±20C, 5±20C and -15±20C. The paneer cubes of 2.5 cm size served as control. It was revealed that the paneer cube of 1.5 cm cube size with 1.2 % salt application had the longest shelf life as evidenced by the sensory scores; supported by lower TBA, FFA and NPN values. Paneer cubes of 1.5 cm size had a score above “like slightly†even on the tenth day of storage at 50C. All the samples stored at -150C were acceptable on 60th day; however, paneer cubes of 1.5 cm size and 1.2% salt scored high on the sensory scale.
