SECTION 4: MECHANISM OF ACTION

Property Description
Sweetness Perception Activates sweet taste receptors on the tongue; Provides 70% of sucrose sweetness; Unique cooling sensation from endothermic dissolution; Enhances flavor profiles.
Zero-Calorie Metabolism Approximately 90% absorbed in the small intestine; Excreted unchanged in urine (no metabolism); Only 10% reaches the large intestine; Provides virtually zero calories (0 kcal/g).
Blood Sugar Regulation Does not raise blood glucose levels; Does not stimulate insulin secretion; Glycemic index of 0; Safe for diabetics.
Dental Health Non-fermentable by oral bacteria; Does not produce acids that cause tooth decay; Reduces plaque formation; Promotes oral health.
Digestive Tolerance Rapidly absorbed in the small intestine; Minimal exposure to gut bacteria; Does not cause gas, bloating, or laxative effects; Better tolerated than other polyols.
Cooling Effect Absorbs heat during dissolution (endothermic); Provides a refreshing, cool sensation in the mouth; Enhances mint and fruit flavors.

SECTION 5: PRODUCTION PROCESS

Industrial Production Method (Fermentation):

Process Flow:
Glucose (Corn or Wheat Starch) → Yeast Fermentation (Osmophilic yeast) → Filtration → Purification → Decolorization → Concentration → Crystallization → Centrifugation → Drying → Milling → Final Product

Step-by-Step Description:

  1. Raw Material: Glucose syrup derived from corn, wheat, or cassava starch.

  2. Fermentation: Glucose is fermented using osmophilic yeast (such as Moniliella pollinis or Trichosporonoides megachiliensis) under aerobic conditions.

  3. Filtration: The fermented broth is filtered to remove yeast cells and debris.

  4. Purification: The filtrate is purified through ion exchange and activated carbon treatment.

  5. Decolorization: The solution is decolorized to obtain a clear, colorless liquid.

  6. Concentration: The purified solution is concentrated by evaporation.

  7. Crystallization: The concentrated solution is cooled to allow erythritol crystals to form.

  8. Centrifugation: Crystals are separated from the mother liquor.

  9. Drying: Crystals are dried to achieve the desired moisture content.

  10. Milling: Dried product is milled to achieve the desired particle size.

  11. Final Product: White crystalline powder or granules (≥ 99.5% purity).

Natural Occurrence: Erythritol occurs naturally in fruits (melons, pears, grapes) and fermented foods (soy sauce, wine, beer). However, the concentration is very low, and commercial production is primarily through fermentation.
