Tomato Extract (Lycopene)

Lycopene: Production, Appearance, and Benefits

Production Process

Lycopene, a potent carotenoid pigment, is primarily extracted from tomato (Solanum lycopersicum) or other red fruits through advanced methods:

1. Source Selection:

   • Ripe tomatoes, watermelon, or guava are used, with tomato pomace (skins/seeds) being the most common industrial source.

   • High-lycopene tomato varieties (≥30mg/100g) are preferred.

2. Extraction Methods:

   • Supercritical CO₂ Extraction: Uses pressurized CO₂ (300-500 bar) for solvent-free, high-purity isolation (≥95% lycopene).

   • Ethanol/Hexane Extraction: Traditional method with subsequent purification to remove residues.

   • Fermentation: Microbial biosynthesis (e.g., Blakeslea trispora) for allergen-free lycopene.

3. Purification & Standardization:

   • Crystallization removes impurities, yielding 10-20% lycopene oleoresin or 5-10% water-dispersible powder.

   • Often standardized to 5-20% lycopene content for supplements.

Appearance & Characteristics

• Color: Deep red crystalline powder (pure form) or reddish-brown oleoresin (oil-soluble).

• Solubility: Insoluble in water; soluble in oils (e.g., olive oil) or organic solvents.

• Stability: Sensitive to light/oxygen; often microencapsulated or blended with antioxidants (e.g., vitamin E) for stabilization.

• Odor/Taste: Mildly earthy in pure form; odorless in encapsulated supplements.

Health Benefits

Lycopene’s strong antioxidant properties (100x more potent than vitamin E) offer evidence-backed benefits:

1. Cardiovascular Protection:

   • Reduces LDL oxidation by 40% and improves arterial flexibility.

   • Linked to 17% lower stroke risk (meta-analysis of 12 studies).

2. Cancer Prevention:

   • Prostate cancer: 25% risk reduction with high dietary intake (Journal of Nutrition).

   • Breast/lung cancer: Inhibits tumor growth via anti-angiogenic effects.

3. Skin Health:

   • Oral intake decreases UV-induced erythema by 50%.

   • Boosts collagen density and reduces wrinkles.

4. Eye Protection:

   • Lowers cataract risk by 30% and slows AMD progression.

5. Anti-Inflammatory Effects:

   • Reduces CRP and IL-6 levels in chronic inflammation.

Applications: Used in supplements (softgels, tablets), fortified foods (juices, dairy), and cosmetics (anti-aging serums). Recommended intake: 6–30 mg/day. Unlike beta-carotene, lycopene lacks pro-vitamin A activity but excels in quenching singlet oxygen radicals.

Note: Enhanced absorption when consumed with fats (e.g., olive oil) due to lipophilicity.
