Native corn and potato starch as CO2 gas bubble nucleation agent for low-temperature high-pressure foaming applications

Gas bubble nucleation and its control is one of the most important parameters in industrial foaming applications defining the physical and chemical properties of the end product. It is possible to enhance this process by adding gas bubble nucleation supporting agents. In this work, the potency of na...
