Dry Whole Cloves

Product Overview

This product consists of hand-picked whole cloves, selected for their high essential-oil yield and consistent size grading. The cloves are carefully harvested to ensure quality, purity, and uniformity, making them ideal for use in culinary, pharmaceutical, and aromatic applications.

Common Varieties and Grades

Cloves are primarily derived from the dried flower buds of the Syzygium aromaticum tree, native to the Maluku Islands of Indonesia. The most common variety is the "true clove," which is distinguished by its deep red-brown color, aromatic scent, and high essential oil content.

Grading is typically based on size, shape, color, and oil content. Premium grades include:

• Grade A: Large, uniform buds with bright red-brown color and high essential oil yield
• Grade B: Medium-sized, consistent in shape, with moderate oil content
• Grade C: Smaller or irregular buds, suitable for lower-grade applications

Key Characteristics and Technical Properties

Cloves are known for their strong, warm, spicy aroma and are rich in essential oils, primarily eugenol (up to 70% in high-quality cloves), which contributes to their medicinal and flavoring properties.

Chemical Composition

Key constituents include:

• Eugenol (primary compound, responsible for flavor and antimicrobial activity)
• Chavicol
• Alpha-terpinene
• Myrcene

The essential oil content typically ranges from 10% to 15% in high-quality, hand-picked cloves, with higher yields observed in well-matured, sun-exposed buds.

Harvesting and Production Process

Cloves are harvested when the flower buds are fully formed and just before they open. The buds are hand-picked to avoid damage and ensure only the highest quality material is selected.

After harvesting, the cloves are dried naturally in well-ventilated, shaded areas to preserve essential oils. The drying process can take several days to weeks, depending on climate and humidity. Once dried, the cloves are sorted by size, color, and oil content, then graded and packaged.

Hand-picking ensures minimal contamination and maintains the integrity of the essential oils, resulting in a superior product compared to mechanically harvested alternatives.

Common Uses and Applications

Cloves are widely used in:

• Culinary applications: Used in spice blends, baking, and savory dishes such as curries, stews, and meat rubs
• Pharmaceuticals: As a natural antiseptic, analgesic, and anti-inflammatory agent
• Essential oil production: Extracted for use in aromatherapy, perfumery, and natural health products
• Flavoring in beverages and confectionery
• Traditional medicine: Used in remedies for toothaches, digestive issues, and respiratory ailments

Quality and Grading Standards

Quality is determined by several factors:

• Essential oil yield (measured via gas chromatography)
• Color and appearance (deep red-brown indicates maturity and oil content)
• Size and uniformity (consistent size ensures predictable flavor and performance)
• Free from foreign matter, mold, or insect infestation

International trade standards such as those from the International Organization for Standardization (ISO) and the Codex Alimentarius provide guidelines for clove quality, including moisture content (typically below 8%), oil content, and microbial safety.

Typical Packaging and Trade Context

Hand-picked whole cloves are commonly packaged in moisture-resistant, airtight containers such as aluminum foil-lined bags or vacuum-sealed pouches to preserve freshness and prevent oxidation.

Standard packaging sizes range from 500g to 2kg per bag, with export-grade packages often including tamper-evident seals and clear labeling of origin, grade, and essential oil content.

Cloves are traded globally, with major export regions including Indonesia, India, and the Philippines. They are commonly shipped in bulk via sea freight, with demand driven by the food, beverage, and pharmaceutical industries.
