The invention belongs to the technical field of
new materials and packaging, and discloses a hydrophobic BA-coated SiO2
nanoparticle and high-
viscosity liquid food anti-sticking
coating and a preparation method and application thereof.The preparation method comprises the following steps that zein and
genipin are taken and added into an
ethanol solution, oscillation is conducted till the zein and the
genipin are completely dissolved, and a Zein-
ethanol solution is obtained; adding the hydrophobic BA-coated SiO2 nanoparticles into absolute ethyl
alcohol, carrying out ultrasonic treatment until the particles are uniformly distributed, then adding a Zein-
ethanol solution, and uniformly mixing to obtain an anti-sticking
coating system; and uniformly spraying the anti-sticking
coating system onto a clean
glass slide by using a handheld spray gun, and
drying at
room temperature for 5 minutes to obtain the anti-sticking coating. The high-
viscosity liquid food anti-sticking coating is prepared through a spraying method, operation is easy, consumed time is short, and the high-
viscosity liquid food anti-sticking coating can be simply and conveniently applied to the inner walls of existing
food packaging bottles in various shapes. The anti-sticking
coating system is sprayed to the surface of a base material through a spray gun, and the high-viscosity liquid food anti-sticking coating can be obtained after room-temperature
drying.
