Entry title

Objective

Form a zein protein film using zein, ethanol, and glycerol.

Description

Zein protein film formation with BSA conjugated NPs was carried out as follows. First of all, a clear solution of zein (10% w/v) in aqueous ethanol (90% v/v) along with glycerol (30% on zein weight basis) as plasticizer was prepared. Five grams of this filmogenic solution was placed in a 9 cm diameter plastic Petri dish and gently swirled to coat the bottom of the dish. It was placed without a lid on a level surface (checked with a spirit level) in an oven at 40°C for 24 h.

Notes

  • 1 gram of zein was measured with 237 microliters of glycerol and a solution of 9mL ethanol and 1 mL water was added to the mixture to reach 10 mL.
  • After mixing 5 grams was weighed out in a petri dish and put in an oven which was then set to 40C.
  • Density of glycerol 1.261 g/cm3
