Green leaves and botanical ingredients — the foundation of clean label food products made with recognizable, natural ingredients.

Consumer demand for natural, clean-label products has transformed the food, beverage, and supplement industries. Plant extracts and natural sweeteners are at the forefront of this shift, offering manufacturers the ability to replace synthetic additives with ingredients that consumers recognize and trust.

This article provides an overview of the key plant extracts and sweeteners in the market, their applications, and guidance for bulk sourcing.

The Clean Label Trend

Clean label is not a regulated term, but it generally refers to products that:

- Use recognizable, simple ingredients
- Avoid artificial additives, preservatives, and colors
- Feature natural sources of flavor, color, and sweetness
- Provide transparent and simple ingredient lists

Plant extracts and natural sweeteners are ideal clean-label ingredients because they are derived from botanical sources and carry functional benefits beyond basic nutrition.

*Plant extracts are derived from botanical sources including leaves, roots, fruits, and seeds — each offering unique bioactive compounds for functional food applications.*

Sweetness: 200-350 times sweeter than sugar
Calories:Zero
Applications: Beverages, tabletop sweeteners, dairy, confectionery
Typical Specification: RA 80%, RA 95%, RA 99%

| Grade | RA Content | Best Use |
| Stevia 80% RA | ≥ 80% | General purpose, cost-effective |
| Stevia 95% RA | ≥ 95% | Clean taste, reduced bitterness |
| Stevia 99% RA | ≥ 99% | Premium applications, minimal aftertaste |

 2. Monk Fruit Extract (Luo Han Guo)

Source: Siraitia grosvenorii fruit
Key Compounds: Mogrosides (especially Mogroside V)
Sweetness: 150-250 times sweeter than sugar
Calories: Zero
Applications: Beverages, tabletop sweeteners, baked goods, sauces
Typical Specification: ≥ 25% Mogroside V, ≥ 50% Mogroside V

### 3. Thaumatin

**Source:** Thaumatococcus daniellii fruit
Sweetness: Approximately 2,000 times sweeter than sugar
Calories: Near zero
Applications: Flavor enhancer, sweetness potentiator, chewing gum
Typical Specification: ≥ 16% protein content

 Formulation Considerations

 Using Plant Extracts

- Solubility: Verify water or oil solubility based on your application
- Color impact: Some extracts (green tea, grape seed) may add color
- Taste profile: Botanical extracts can have bitter or astringent notes
- Dosage range: Start low and adjust; active compound concentration varies greatly by extract ratio

 Using Natural Sweeteners

| Factor | Stevia | Monk Fruit | Thaumatin |
|--------|--------|------------|-----------|
| Heat Stability | Good up to 200°C | Good | Good |
| pH Stability | 2-10 | 2-10 | 3-8 |
| Solubility | Good in water | Good in water | Soluble |
| Flavor Profile | Some licorice aftertaste (varies by grade) | Clean, fruity notes | Sweet, slight licorice |

Blending Strategy: Many manufacturers combine stevia with monk fruit or erythritol to improve taste profile and mouthfeel.

*Rigorous quality testing — including HPLC fingerprint analysis, solvent residue screening, and heavy metal testing — ensures the purity and safety of natural ingredients.*

 Sourcing Considerations

Quality Parameters for Plant Extracts

- Identification: HPLC fingerprint matching reference standard
- Assay: Active compound content per specification
