摘要:
IN THE PREPARATION OF COLLAGEN DOUGH THE EXTRACTABILITY, WHICH IS A MEASURE OF ACID SOLUBILITY, IS DETERMINED BY EXTRACTION WITH AN ACID, CENTRIFUGATION, AND DETERMINATION OF ACID-SOLUBLE MATTER IN THE LIQUID PORTION. EXTRACTABILITY WITHIN A RANGE OF 8% TO 16%, DRY WEIGHT BASIS, A SOLIDS CONTENT WITHIN THE RANGE OF 4.5% TO 6.5% DRY WEIGHT BASIS, AND AN APPARENT VISCOSITY BETWEEN 45 TO 80 POISES ARE CHARACTERISTICS WHICH MINIMIZE VARIATIONS IN QUALITY AND PROVIDE A GREATER PROPORTION OF SATISFACTORY CASINGS FOR SAUSAGES OR THE LIKE.

A modeling composition is disclosed including mineral fillers such as clay and talc, hydrocarbon petroleum distillate oil, waxy paraffinic hydrocarbon oil, a liquid silicone compound, an astringent, a humectant, glue and water. The composition may be shaped and then permanently set.
WHEREIN X IS AN ANION OF AN ACID AN IONIZATION CONSTANT OF A LEAST 10-2, HAS BEEN FOUND TO PROVIDE A GELATIN HARDENING FUNCTION WHEN UTILIZED THEREWITH.
