1、Powder dissolution through new eyesPowderPowder dissolution through new eyesWhat properties should a powder have to dissolve quickly and efficiently in a liquid and how can the process be predicted?These are issues of great importance to tens of thousands of food producers around the globe,for whom

2、more efficient processes can bring biggains in product quality,energy saving and investment cost.A research project funded by Tetra Pak has provided new knowledge and changed an old truth about what determines how a powder dissolves.2Dissolving spray-dried powder in a liquid is among the most common

3、 industrial processes,and one applied in a wide range of industries.Ineffective dissolution causes a deterioration in final product quality a colour with a divergent nuance,a drug with the wrong concentration,or a liquid food with unappetizing lumps.It can also mean increased energy costs and higher

4、 waste.In the food industry,various types of spray-dried powders are used in a diverse range of processes.They can be added as thickeners,stabilizers or emulsifiers in powder form to give liquids desired properties,or to recombine an original product.The advantages of using powder in the food indust

5、ry include reduced weight and transportation costs and a prolonged storage time due to low water activity.Dissolution needs to be fast and efficient,whether in large-scale industrial processes or in the home.It is vital to avoid the powder forming gelled lumps,known as“fisheyes”,instead of dissolvin

6、g.Regardless of the scale,this seemingly simple In a well-designed mixing process,the powder dissolves effectively in the fluid.Less effective dissolution will lead to the formation of lumps so-called fisheyes that are hard to dissolve.process is far more complicated than it may seem,and established
