In order to reveal the mechanism of microwave puffing berry snack, a center combination experiment method was employed to explore the puffing process of blueberry snacks. Blueberry as the raw material, the microwave power, initial moisture content, puffing time and mass were employed as experimental factors. The pressure, temperature, amount of water vapor and puffing properties in terms of the volume, hardness and brittleness were employed as target parameters. The higher microwave intensity and initial moisture content resulted in the more amount of water vapor in the snacks and more holes in the appropriate puffing time. The shape and structure of the snacks tended to be stable with the removal of moisture.
