Problems solved by technology

At present, the key technology of blueberry juice processing has not been completely overcome, which has affected the promotion of blueberry juice in the market

Blueberry fruit is soft and rich in viscous substances such as pectin. During the crushing process, pectin substances dissolve into the juice, which will increase the viscosity of the juice and the adhesion between the juice and the fruit tissue, thereby reducing the permeability and stability of the fruit cake. Capillary liquid penetration, resulting in poor pressing performance, low utilization rate of raw materials, high production cost, more processing waste, and low juice yield
