1. Hydrocolloid Selection: Pectin vs. Gelatin Matrix Mechanics
Gelatin Systems: Gelatin provides a elastic, bouncy chew with a lower melting threshold (~37°C). However, gelatin is animal-derived, prone to cross-linking over time (resulting in hardened, unpalatable product), and highly susceptible to heat degradation during international shipping container transit.
Pectin Systems (HM vs. LM): High-Methoxyl (HM) Citrus Pectin creates a clean, quick-bite texture with superior heat tolerance (up to 60°C). Gelation requires precise parameters: soluble solids between 62%–68% Brix and strict pH control ($3.2 - 3.5$). Low-Methoxyl (LM) Pectin relies on divalent cation cross-linking (such as Calcium $Ca^{2+}$), enabling keto-friendly and zero-sugar recipe development without high sugar solids.
