Hi Zoya. Thanks for your reply. ????

There is 20% butter in the formulation. The final product should be soft enough to be filled below 30 °C, but also thick enough to avoid run-off tubes (packaging) and oil separation.

The viscosity of larger batch is already twice as high as that of smaller batch. During cooling, the stirring speed of the 1.2 kg batch is twice as high as that of the smaller batch.

I think it is really difficult to figure out the reason or a solution. Based on my knowledge, the lipophilic interaction is hard to control. As you said, the air in the product has also an impact on the viscosity.

Maybe I should re-formulate the product so that I dont need to homogenise the product at the end. (for this formulation I have to, cause the texture is very rough/grainy)

I’d be very glad to hear your ideas. THANKS!
