Note: Means with different letters in the same column show significant (p < .05) differences between treatments and storage period. R₀ = Control (Rasmalai) treatment (without addition of any preservative); R₁ = Rasmalai prepared using 500 ppm potassium sorbate; R₂ = Rasmalai prepared by using 1000 ppm potassium sorbate; R₃ = Rasmalai prepared by using 500 ppm calcium propionate; R₄ = Rasmalai prepared by using 1000 ppm calcium propionate; R₅ = Rasmalai prepared using combination of both potassium sorbate and calcium propionate in equal quantity, i.e., 500 ppm each.
