Fluid shear is the mechanical force exerted by the movement of fluids over cell surfaces and has been found to play an important role in cellular differentiation, development and function.
The foam stability of draft beer was decreased by lowering temperature quickly and the mechanical shear power which yeast cell could be damaged.
降温速度过快、离心泵及薄板换热器的机械剪切力会破坏酵母细胞，降低纯生啤酒泡沫稳定性。
