White Tea Absolute (Camellia Sinensis)

White Tea Absolute (Camellia Sinensis)

Camellia sinensis, an evergreen shrub, is highly valued for producing white tea and tea seed oil. Below is a detailed overview of its cultivation, extraction processes, and uses:

Cultivation of Camellia Sinensis

• Geography: Native to Asia, Camellia sinensis is now cultivated worldwide, especially in tropical and subtropical regions.

• Plant Characteristics: The shrub is trimmed to below 2 meters for optimal leaf harvesting. Leaves range from 4–15 cm long and 2–5 cm wide.

• Preferred Conditions:

  • Requires 127 cm or more of annual rainfall.

  • Thrives in USDA climate zones 7–9 with full or partial sunlight.

  • Grows best in acidic, well-drained soils.

• Harvesting: Young leaves with short white hairs (light green color) are preferred for tea production. These hairs give the plant a whitish appearance, hence the name "white tea."

• Varieties: Two primary varieties are cultivated:

  • Chinese variety: Smaller leaves, suited for cooler climates.

  • Assamese variety: Larger leaves, adapted to warmer climates138.

White Tea Production

White tea is the least processed form of tea and is made from young buds and leaves. The process involves:

• Hand-plucking the choicest buds and leaves.

• Withering to allow slight oxidation.

• Drying to preserve delicate flavors and aromas.

White tea is rich in antioxidants, low in caffeine, and ideal for relaxation. Popular varieties include Darjeeling White Tea and Silver Needle White Tea2710.

Tea Seed Oil Extraction

The seeds of Camellia sinensis can be pressed to produce tea seed oil, a pale green edible oil with herbal aroma. Extraction methods include:

• Cold Processing: Preserves nutrients by avoiding heat.

• Solvent Extraction: Uses chemicals to extract oil efficiently.

• Supercritical CO₂ Extraction: Produces high-purity oil by applying specific pressure and temperature conditions5.
