ObjectiveTo prepare a zein protein film. Description
ethanol solution: 90% v/v solution = 9mL ethanol, 1mL water 10% w/v zein = 0.1 g/mL, 1g zein in 10 mL 30% glycerol on zein weight basis = 0.3g glycerol 0.3g glycerol x 1 mL / 1.261g = 0.238 mL Data
NotesThe resulting film was more brittle than the others and came off in pieces rather than a large round film. The cause is mostly likely too little glycerol.
