In meat products process, What are the core processing points for using konjac gum?

The core is solving its dissolution challenge. You must follow the "Golden Two-Step Method": High-Shear Cold Dispersion + Heat Activation.

Wrong Practice: Pouring directly into hot water → Instantaneous gelatinization and clumping, forming insoluble "konjac lumps" that cause gritty defects in the final product.

Correct Process Flow:

1. Pre-mixing (Key Preparation):

   • Thoroughly and uniformly dry-mix the konjac gum powder with 5-10 times its weight of dry ingredients like sugar, salt, or starch. This step effectively prevents subsequent clumping upon contact with water.

2. High-Shear Cold Dispersion (Step 1):

   • Add ice water (temperature < 10°C) to the mixing vessel.

   • Start the high-speed mixer (≥1500 rpm) to create a strong vortex.

   • Slowly and evenly sprinkle the pre-mix into the center of the vortex. The high shear force will instantly disperse it, forming a preliminary suspension.

3. Heat Activation (Step 2):

   • While continuing to stir, slowly heat the suspension to 80-85°C.

   • Maintain stirring at this temperature for 5-10 minutes. During this time, the konjac glucomannan molecules will fully hydrate and expand, transforming the solution into a homogeneous, transparent, viscous gum solution.

4. Blending and Mixing:

   • Thoroughly mix the fully dissolved konjac gum solution with the previously prepared and fully dissolved carrageenan solution (which also typically requires heating) at 60-70°C. This yields the blended gum solution ready for subsequent injection or tumbling.
