Abstract
The present invention describes a gelatin having a high molecular weight fraction (>250,000 Daltons) of from 0 to 25 wt %, a beta fraction (150,000-250,000 Daltons) of from 0 to 20 wt % and an alpha fraction (50,000-150,000 Daltons) of from 15 to 55 wt %. The gelatin has a gel strength of from 200 to 400, an absorbance a 420 nm of from 0 to 0.068 and a concentration of protease of greater than 10 ppb.
