MonkVee® Pure Stevia Leaf Extract - Lab Analysis

-

Key Identification

-

  • Product Name: Stevia Extract
  • Latin Name: Stevia rebaudiana
  • Plant Part Used: Leaf
  • Extraction Solvent: Water
  • Active Ingredient: Stevioside (general category of steviol glycosides)
  • Batch Size: 1000kg (large-scale industrial batch)
  • Country of Origin: China

👉 This confirms it’s leaf-extracted, not fermentation.

-

Active Ingredients

-

  • Assay: RA 97%
  • “RA” = Rebaudioside A (Reb A).
  • 97.32% purity (by HPLC testing) → meaning almost the entire powder is Reb A.

This is NOT Reb M and is high-purity Reb A extracted from the stevia leaf.

-

Physical Control

-

  • Appearance: Fine white powder → confirms the crystalline, talc-like texture.
  • Odor: “Characteristic” → standard stevia aroma.
  • Taste: Sweet → expected.
  • Sieve Analysis: 97% passes through an 80-mesh sieve → shows it’s finely milled.
  • Burned Residue % (Ash): 0.07% (very low → high purity).
  • Loss on Drying %: 1.81% → little water content (dry, shelf-stable).
  • Absorbency %: 0.007 → almost no UV absorption (clean compound).
  • pH: 5.11 → mildly acidic, normal for stevia extract.

-

Solvent Residue

-

  • Ethanol: 855 ppm (well below 5000 ppm limit).
  • Methanol: 50 ppm (well below 200 ppm limit).

Both safe. These are common in herbal extractions; levels are minimal.
-

Chemical Control

-

  • Arsenic <1 ppm, Lead <1 ppm, Heavy Metals <10 ppm → all within safe global food limits.
  • Pesticide Residues: ND (Not Detected).

👉 Clean and food-grade safe.
-

Microbiological Control

-

  • Total Plate Count: <1000 CFU/g (well under limits).
  • Yeast & Mold: <100 CFU/g.
  • Coliforms: <30 MPN/100g.
  • E. coli, Salmonella, Staph aureus: All Negative.

👉 Microbiologically safe and compliant with food standards.
-

Packing and Storage

-

  • Packing: 20 kg/carton, double-bagged inside paper drums → typical bulk raw material format.
  • Storage: Cool, dry place, no sunlight.
  • Shelf Life: 2 years.

Overall Meaning

  • This COA confirms the ingredient is:
  • Rebaudioside A (Reb A) 97% purity
  • Extracted from stevia leaf using water extraction
  • Finished as a fine white crystalline powder
  • Free of dangerous contaminants, solvents, pesticides, or microbes.
  • Not Reb M (which would only be present in trace amounts in real leaf, and when sold commercially is almost always fermentation-derived).

MonkVee® Golden Monk Fruit Sweetener - Lab Analysis

-

Key Identification

-

  • Product Name: Monk Fruit Erythritol Granules
  • Quantity: 20,000 kg
  • Country of Origin: China

-

Active Ingredients

-

  • Assay (Sweetness): “1 time as sugar” → meaning it is intended to be a 1:1 sugar replacement in sweetness intensity.

    Erythritol is ~70% as sweet as sugar, and monk fruit extract (extremely sweet) is blended in small amounts to bring it up to exact sugar equivalence.

-

Physical Control

-

  • Appearance: Golden yellow granule (slightly off-white/yellow, due to monk fruit extract mixed with erythritol).
  • Odor: Characteristic (no unusual smells).
  • Taste: Sweet (sugar-like).
  • Moisture Content: 0.03% (well below the 5.0% limit, which means it’s dry and shelf-stable).

-

Chemical Control

-

  • Arsenic (As): <0.1 ppm (limit 0.5 ppm).
  • Cadmium (Cd): <0.01 ppm (limit 0.5 ppm).
  • Lead (Pb): <0.1 ppm (limit 1 ppm).
  • Mercury (Hg): <0.01 ppm (limit 0.1 ppm).
  • Heavy Metals: <10 ppm (limit 10 ppm).

👉 All heavy metals are well below food-safety thresholds.

-

Microbiological Control

-

  • Total Plate Count: 30 CFU/g (limit 1000) → very clean.
  • Yeast & Mold: 10 CFU/g (limit 100) → excellent.
  • Coliforms: <10 MPN/100g (limit 30).
  • E. coli: Negative (conforms).
  • Salmonella: Negative (conforms).
  • Staphylococcus aureus: Negative (conforms).

👉 Microbiologically safe — extremely low microbial load.

-

Packing and Storage

-

  • Packing: 20 kg or 25 kg per bag, in kraft bags with inner plastic lining.
  • Storage: Store in a cool, dry place with no direct sunlight.
  • Shelf Life: 2 years.

Overall Meaning

  • This COA confirms the product is:
  • A Monk Fruit + Erythritol blend in granular form
  • Calibrated to be 1:1 sweetness with sugar
  • Clean and food-safe, with extremely low levels of contaminants, heavy metals, and microbes
  • Dry, stable, and suitable for long-term storage (2 years shelf life)
