PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Lao Laab is a lacto‑fermented cucumber product that uses salt and glutinous rice flour to promote heterofermentative lactic acid bacteria, rapidly acidifying the matrix while preserving crisp texture.
Origin: Lao people (Traditional / pre‑industrial) — Lao PDR, Northern Thailand (Isan)
See full technique reference →During fermentation, heterofermentative LAB convert sugars from glutinous rice flour into lactic acid, acetic acid, ethanol, and CO₂, lowering the pH to ≤4.0. The acidic environment inhibits spoilage organisms and preserves the cucumbers, while the presence of salt and limited oxygen creates a micro‑aerobic niche that favors LAB over yeasts and clostridia.
Primary Reaction
lactic acid fermentation by heterofermentative Lactobacillus plantarum
