Oolong Tea Extract Powder

Introduction

Oolong tea—a well-known semi-fermented tea originating from China—is now widely produced in Vietnam, especially in regions like Lam Dong and Bao Loc. Rich in polyphenols, catechins, theaflavins, and EGCG, oolong tea offers numerous health benefits.

Oolong tea extract powder is manufactured to concentrate these valuable bioactive compounds, making it suitable for use in the food, cosmetics, and natural pharmaceutical industries.

Oolong Tea Extract Powder Production Process

1. Raw Material Selection

• Source: Oolong tea leaves that meet VietGAP or organic standards.

• Requirements: Dried tea leaves processed using the semi-fermentation method (30–70%), retaining a bright green-yellow color.

2. Extraction

• Conditions:

  • Temperature: 75–85°C

  • Time: 3–5 minutes

  • Tea-to-solvent ratio: 1:6 or 1:8, depending on desired strength

• Note: Oolong tea contains a significant amount of EGCG and theaflavins, so it is essential to strictly control temperature to preserve its active compounds and distinctive aroma.

3. Filtration and Concentration

• Filtration: Use centrifugal separation to remove tea residues.

• Concentration: Vacuum concentration at low temperatures (50–55°C) to preserve bioactive compounds.

4. Spray Drying

• The concentrated extract is sent to a spray dryer.

• Drying Parameters:

  • Drying chamber temperature: 150–170°C (not exceeding 180°C)

  • Final powder moisture content: ≤5%

• Result: Fine, fully water-soluble oolong tea extract powder with a light lemon-yellow color and a characteristic mild aroma.

5. Packaging and Storage

• Packaging: Specialized moisture-proof and oxygen-resistant packaging.

• Storage: Keep in a cool, dry place at temperatures below 25°C.
