In meat products, why the hydrocolloids formed gel become weakening and purge in acidic environments?

Core Issue: Acid Stability. Most gums are stable between pH 4-7.

Highly Stable: Xanthan gum (stable from pH 1-13), Gellan gum.

Unstable: Carrageenan undergoes hydrolytic degradation at pH < 4.0 under heat, losing gelling power. Konjac gum viscosity drops sharply when heated under strong acidic conditions.

Solution:

Choose the Right Gum: For acidic products, prioritize xanthan gum and gellan gum.
Process Adjustment: Acidify after stuffing/cooking and sterilization, avoiding prolonged heating of gums under acidic conditions.
Use Buffering Salts: Such as sodium citrate, to stabilize the system pH within the gum's tolerance range.
