Study on filming technology for nano-SiOx/albumin complex edible film

Taking the albumin as raw material and adding nano-SiOx, plasticizer, intensifier, cross-linker, nano-composite films were achieved through casting technique and its filming technology and parameters were studied in this article.The results showed that the best filming technology and parameters of the nano-SiOx/albumin complex film as follows:8% albumin dissolved in water, adding 0.1% nano-SiOx, ultrasonic dispersed evenly, adding 0.3% plasticizer, 0.55% intensifier and 0.7% cross-linker, water bath heating and stirring, antifoaming the film liquid by adding 0.06% edible antifoaming agent, ultrasonic degassing under 90W of power, 30min, casting film on the plastic board coated with 0.05mL/100cm2 Tween 80, drying for 3 hours under the hot wind of 60℃, taking off the film and keeping in reserve.Under this condition, the properties of composite films were (3.68±0.046) MPa, 57.2%±0.361%, (4.84±0.436) g·mm/ (m2·d·kPa) .
