Abstract
This invention relates to the field of functional materials technology and discloses a method for preparing polyethylene glycol-modified soy protein isolate gel, comprising: Step 1, crushing soybeans and collecting the crushed soybeans; Step 2, extracting protein from the crushed soybeans to obtain soy protein isolate; Step 3, modifying the soy protein isolate with polyethylene glycol to obtain modified soy protein isolate; Step 4, mixing the modified soy protein isolate, basalt powder, and corn stalk powder, then granulating and crushing to obtain soy protein isolate powder; Step 5, preparing the polyethylene glycol-modified soy protein isolate gel by combining the soy protein isolate powder, theophylline, resin, and liquid paraffin. The polyethylene glycol-modified soy protein isolate gel prepared by this invention can effectively adsorb and fix heavy metal ions from water, purify water quality, and reduce the risk of heavy metal wastewater to the ecosystem and human health.
