Product Description

Tartrazine (CAS No.: 1934-21-0, E Number: E102) is a highly reliable water-soluble azo dye, presenting as a bright lemon-yellow crystalline powder. Formulated specifically for the commercial food and beverage industry, it delivers vivid, consistent hues that meet stringent global safety standards. With an exceptional purity level of ≥98.5% and a strictly controlled moisture content of ≤ 1.5%, this food-grade colorant ensures rapid dissolution and uniform dispersion in various formulations. It offers a versatile 12-shade color spectrum, ranging from pale lemon to deep gold, allowing manufacturers to achieve precise visual profiles.

Certified under FDA 21 CFR §74.705, EU Regulation (EC) No. 1333/2008, and China’s GB 4481.1-2019, our tartrazine guarantees exceptional safety by maintaining heavy metal traces well below regulatory limits (lead ≤ 0.1ppm, arsenic ≤ 0.05ppm). This strict compliance significantly reduces formulation risks and ensures smooth market entry for international buyers.

Safe Tartrazine for Coloring

Product Benefits

  • Fluorescent Safety: Undergoes rigorous photostability testing to maintain intense color saturation without hazardous fluorescence emission. It successfully passes EU 10/2011 migration limits for food contact materials, ensuring overall end-product safety.
  • Broad pH Adaptability: Formulated to retain structural stability across a wide pH range of 3.0–9.0. This prevents unwanted fading or color shifting in highly acidic beverages (such as lemonade) as well as alkaline bakery goods (like cakes containing baking soda), ensuring visual consistency throughout the product's shelf life.
  • Cost-Effective Coloring: Thanks to its high tinting strength, it requires only a minimal 0.01%–0.05% addition rate to achieve the target shade. This efficiency can reduce raw material coloring costs by up to 60% when compared to natural alternatives like curcumin, optimizing overall production budgets.
  • Heat & Light Resistance: Engineered for demanding industrial processing, it withstands baking temperatures up to 180°C and resists UV exposure for up to 12 months without noticeable discoloration. This thermal and photostability outperforms natural yellow 6, minimizing product return risks due to visual degradation.
  • Regulatory Compliance: Fully certified Halal (IFANCA), Kosher (OK), and vegan-friendly. This comprehensive certification profile makes it suitable for both conventional and specialized food production worldwide, helping brands expand into diverse consumer markets.

Usage & Applications

  • Beverages: Typically added at 0.01%–0.03% in carbonated drinks, fruit juices, and sports hydration formulas. It creates consistent, bright lemon-yellow tones in iced teas and clear beverages without causing precipitation or cloudiness.
  • Confectionery: Incorporated at 0.02%–0.05% in hard candies, gummy bears, and lollipops. It also blends seamlessly with Red 40 to produce vibrant orange shades ideal for citrus-flavored treats.
  • Bakery Goods: Used at 0.03%–0.04% in cake mixes, cookies, and pastries. The colorant maintains its vibrancy and prevents browning or dullness even during a standard 20-minute baking cycle at 175°C.
  • Dairy Products: Mixed into yogurt, puddings, and ice cream at 0.01%–0.02%. It remains highly compatible with active probiotics and complex dairy proteins, delivering visual appeal without any flavor interference.

Tartrazine Food Applications

FAQ

Q: Is tartrazine safe for children and sensitive populations?

A: Yes. Our product strictly meets the JECFA’s Acceptable Daily Intake (ADI) standard of 7.5mg/kg body weight. Clinical studies indicate that < 0.1% of individuals exhibit sensitivity, which remains well below the global average for commercial food dyes, making it a reliable choice for mass-market consumption.

Q: How to store tartrazine to preserve color stability?

A: For optimal preservation, store the powder in opaque, sealed containers at a controlled temperature of 15°C–25°C with relative humidity ≤ 50%. Avoid direct sunlight exposure. Under these proper storage conditions, the shelf life extends up to 36 months, reducing inventory waste.

Q: Can it be blended with other food colorants?

A: Absolutely. It mixes seamlessly with Sunset Yellow (E110) for rich amber tones and Brilliant Blue (E133) for vivid green shades. The optimal blending ratio is typically 1:1 for achieving stable secondary colors in complex food and beverage formulations.

Advantage

When sourcing coloring agents for diverse manufacturing requirements, consistency, safety, and performance stability are primary concerns for procurement professionals. Our Safe Tartrazine is engineered to meet these exact standards across multiple industries, backed by a highly controlled manufacturing foundation.

The reliability of our tartrazine stems from strictly regulated preparation techniques. It is primarily synthesized through the condensation method and the diazo coupling process (heavy ammonia-coupling method). These established chemical processes allow for precise control over the molecular structure, resulting in a standardized water-soluble synthetic pigment with a bright, tender yellow hue. For formulation engineers and buyers, this ensures every batch delivers consistent tinting strength and stability, significantly reducing the risk of color variation in final products. The meticulous production environment guarantees the pigment remains free from unwanted impurities, aligning with the safety standards required for sensitive applications.

Cross-Industry Versatility & Application Value

While widely recognized in the food sector for enhancing the visual appeal of frozen desserts, jellies, flavored fermented milk, beverages, canned goods, and candy coatings, the true procurement advantage of this tartrazine lies in its broad cross-industry adaptability.

  • Pharmaceuticals and Cosmetics: The pigment is highly suitable for coloring medicinal capsules, syrups, and cosmetic formulations. Its reliable water solubility ensures even distribution, providing clear product identification and enhanced aesthetic appeal without compromising formulation safety.
  • Industrial Manufacturing: Beyond consumables, tartrazine serves as a critical dyeing agent in coatings, inks, plastics, and stationery. In these industrial applications, the pigment offers strong color retention and uniform dispersion. These properties are essential for maintaining the visual integrity of manufactured goods under varying environmental conditions and prolonged storage.
  • Textiles and Lake Manufacturing: It is also effectively utilized for dyeing natural fibers such as wool and silk, as well as in the production of color lakes, demonstrating its strong binding properties and vibrant finish.

Comprehensive Corporate Strength & Supply Chain Reliability

Choosing the right pigment requires a manufacturing partner capable of delivering consistent scale, quality assurance, and logistical support. Our comprehensive corporate infrastructure is designed to provide buyers with complete peace of mind and long-term value.
