Using fiber active variant only for the formulation in the DOE:
1. Repeat pilot using last year process 1 batch – this will be reference (this failed last week). It needs to be repeat next week
2. Using same process, do reduce lactic acid level – this is to see the impact of lactic acid whether this will help increase viscosity
3. Using same process, do use the cooling rate we saw in last year MPT to confirm the impact of cooling rate
