Retort Sterilization and Hydrocolloid Stability in RTD Bubble Tea
RTD (Ready-to-Drink) Bubble Tea requires sophisticated food engineering to maintain the texture of "Tapioca Pearls" (Boba) in a shelf-stable liquid. Standard starch-based pearls would dissolve or turn mushy over time
To solve this, engineers use Konjac-based pearls or "Cold-Setting" alginate spheres. The liquid—a blend of tea extract and milk solids—undergoes UHT (Ultra-High Temperature) processing or "Retort Sterilization" to eliminate microbial life. To prevent the tea from "Separating" or the milk proteins from "Denaturing" during heating, the formula utilizes Stabilizers like Carrageenan and Xanthan Gum. The "Mouthfeel" is maintained through high-shear homogenization, ensuring that fats are evenly distributed as microscopic droplets.
