Food Grade Garlic Oleoresin Solvent Extraction Liquid Extract in Bottle

Food Grade Garlic Oleoresin Solvent Extraction Liquid Extract in Bottle

Food grade garlic oleoresin solvent extraction liquid extract in bottle is a concentrated, liquid form of garlic derived from the solvent extraction of garlic oil. This product is produced by extracting natural compounds from garlic cloves using a solvent process, preserving the bioactive components such as allicin, diallyl sulfides, and other organosulfur compounds. It is widely used in the food, dietary supplement, and pharmaceutical industries due to its potent biological activity and natural origin.

Product Overview

Garlic oleoresin is a natural extract obtained from garlic bulbs through a solvent extraction process. The resulting liquid extract is typically clear to pale yellow, with a characteristic garlic aroma. It is considered food-grade and meets international safety standards for use in human consumption and food fortification.

The solvent extraction method ensures a high yield of active compounds while minimizing the presence of undesirable residues. The final product is stable, shelf-life extended through proper packaging, and suitable for use in both raw and processed food applications.

Common Varieties and Grades

Garlic oleoresin is available in various grades based on purity, concentration, and processing methods:

• Standard Food Grade: Contains 10–20% total sulfur compounds, suitable for general food and supplement use.
• High-Activity Grade: Higher concentration of allicin and organosulfur compounds, ideal for targeted health supplements.
• Organic Certified: Produced from organically grown garlic, with no synthetic pesticides or fertilizers.

Grading is typically based on the concentration of allicin, total sulfur content, and absence of contaminants such as heavy metals or microbial impurities.

Key Characteristics and Technical Properties

Chemical Composition

The primary active constituents include:

• Allicin (a volatile sulfur compound with antimicrobial and antioxidant properties)
• Diallyl sulfide (DAS) and diallyl disulfide (DADS)
• Allicin precursors (such as alliin and alliinase enzymes)
• Organosulfur compounds with vasodilatory and anti-inflammatory effects

Physical Properties

Appearance: Clear to pale yellow liquid
Odor: Strong, characteristic garlic aroma
pH: Slightly acidic (typically between 4.0 and 5.5)
Specific Gravity: 1.00–1.05
Storage Stability: Stable at room temperature when stored in dark, airtight containers

Production and Harvesting Process

Garlic oleoresin is produced through a multi-step process:

1. Garlic bulbs are harvested at peak maturity, typically in late autumn.
2. After drying and grading, the cloves are crushed to release their essential oils.
3. Extracts are obtained using a solvent such as ethanol or hexane, which dissolves the oil components.
4. The solvent is then removed through evaporation or distillation, leaving behind a concentrated liquid oleoresin.
5. The final product undergoes filtration and quality testing to ensure purity and safety.

The solvent extraction method is preferred over cold pressing due to its higher yield and consistency, while still preserving bioactive compounds.

Quality and Grading Standards

Food-grade garlic oleoresin must comply with international food safety and quality standards, including:

• USDA Food Grade Standards
• EU Regulation (EC) No 1924/2006 on food additives
• ISO 22000 for food safety management
• Good Manufacturing Practices (GMP) for food supplements

Key quality indicators include:

• Low levels of heavy metals (e.g., lead, arsenic)
• Minimal microbial contamination
• High concentration of organosulfur compounds
• Absence of synthetic additives or preservatives

Common Applications

Food grade garlic oleoresin liquid extract is used across multiple industries:

• Dietary Supplements: Added to capsules, tablets, or powders for immune support and cardiovascular health.
• Food Industry: Used as a natural flavoring agent or preservative in sauces, condiments, and processed foods.
• Pharmaceuticals: Incorporated into formulations for antimicrobial and anti-inflammatory effects.
• Functional Foods: Used in fortified beverages, spreads, and health bars.

Its natural origin and proven bioactivity make it a preferred ingredient in clean-label and functional food products.

Typical Packaging and Export Context

The product is commonly packaged in high-quality, food-grade plastic bottles (e.g., 100ml, 250ml, 500ml, or 1L) with child-resistant caps and dark-colored or opaque containers to protect against light degradation.

It is widely exported to regions with growing demand for natural and plant-based ingredients, including North America, Europe, Asia-Pacific, and the Middle East. Export compliance includes adherence to food safety regulations and labeling requirements such as ingredient lists, allergen declarations, and country of origin.
