Keeping Quality of Different Urea Molasses Mineral Block

Three types of urea molasses mineral blocks (B₁, B₂ and B₃) were manufactured using cold process and stored at 20, 30, 40 and 50°C at 40, 48, 56, 59, 61 and 71% relative humidities (RH) for 30 days using static method. Equilibrium moisture content (EMC) was mainly influenced by relative humidity, temperature and type of block. The mean total sugar values were 32.38, 32.18 and 32.17 per cent for B₁, B₂ and B₃ respectively. Per cent loss in total sugar was not significantly (P≤0.05) different among various chemical UMMB's during the storage period. The alcoholic acidity was significantly (P≤0.05) higher in B₁ as compared to B₂ and B₃, There was no visual fungal or mould growth in any UMMB indicating that blocks can be safely stored between 20–500C and 40- 71% relative humidities.
