Effects of polyphenol-rich grape seed and green tea extracts on the physicochemical properties of 3D-printed edible soy protein films
In this research, soy protein isolate (SPI) along with 0%, 1%, 3%, and 5%(w/w) of grape
seed extract (GS) and green tea extract (GT) as natural antioxidants were used to develop
edible active packaging materials using 3D printing technology. In addition, the effects of
nozzle size (0.10, 0.25, and 0.33 mm) and pressure (0.020, 0.035, 0.048, and 0.062 MPa) on
the 3D printing of the films were investigated. The printing accuracy was evaluated by
comparing the areas of the 3D-printed films from their pictures to the area of the digital …
