Safe Tartrazine for Coloring

Product Overview

As a premier factory-direct manufacturer of synthetic colorants, we supply Safe Tartrazine (CAS No.: 1934-21-0, E Number: E102) tailored for large-scale production. This water-soluble azo dye manifests as a bright lemon-yellow crystalline powder, engineered to deliver unparalleled consistency. With a guaranteed purity level of ≥98.5% and moisture content capped at ≤ 1.5%, our coloring solutions ensure vibrant, fluorescent hues that comply strictly with global safety frameworks. We empower food, beverage, and pharmaceutical facilities with a reliable, heavy-metal-controlled (lead ≤ 0.1ppm, arsenic ≤ 0.05ppm) pigment that spans a 12-shade color spectrum from pale lemon to deep gold.

Product Benefits

Verified Fluorescent Safety: Our tartrazine undergoes rigorous photostability testing to ensure it maintains intense color saturation without emitting hazardous fluorescence. It confidently passes the stringent EU 10/2011 migration limits for food contact materials, ensuring complete safety for end-consumers.

Broad pH Adaptability: Engineered to retain absolute stability across a wide pH range of 3.0–9.0. This prevents unwanted fading or shade shifting in highly acidic beverages like lemonades, as well as in alkaline bakery environments such as cakes formulated with baking soda.

Exceptional Cost Efficiency: Formulated for maximum tinctorial strength, requiring only a minute 0.01%–0.05% addition rate to achieve the desired target shade. This high-yield concentration reduces raw material expenditure by up to 60% when compared to natural curcumin alternatives.

Superior Heat & Light Resistance: Designed to withstand aggressive processing conditions, including baking temperatures up to 180°C and extended UV exposure for up to 12 months. It resists discoloration and thermal degradation, significantly outperforming natural yellow 6 in shelf-stable applications.

Comprehensive Regulatory Compliance: Fully certified Halal (IFANCA), Kosher (OK), and 100% vegan. Our pigment aligns perfectly with FDA 21 CFR §74.705, EU Regulation (EC) No. 1333/2008, and China’s GB 4481.1-2019, making it ideal for worldwide distribution.

Usage

Beverage Formulation: Typically added at precise ratios of 0.01%–0.03% in carbonated drinks, fruit juices, and isotonic sports beverages. The fine powder dissolves rapidly to create consistent, brilliant lemon-yellow tones in iced teas and clear liquids without introducing any unwanted cloudiness or sedimentation.

Confectionery Manufacturing: Incorporated at 0.02%–0.05% in the production of hard candies, gummy bears, and extruded lollipops. The dye withstands the high-heat boiling phase of sugar syrups and blends flawlessly with Red 40 to produce vibrant, uniform orange shades for citrus-flavored treats.

Commercial Bakery Goods: Utilized at 0.03%–0.04% in dry cake mixes, cookie doughs, and laminated pastries. The pigment matrix maintains its color vibrancy and resists browning even during prolonged 20-minute baking cycles at 175°C, ensuring a visually appealing crumb structure.

Dairy Processing: Homogeneously mixed into yogurt bases and ice cream vats at 0.01%–0.02%. The colorant is highly compatible with active probiotics and complex dairy proteins, integrating smoothly without causing protein precipitation or interfering with the delicate flavor profile of the dairy matrix.

FAQ

Q: Is your tartrazine formulation compliant with international safety limits for sensitive populations?

A: Yes, our product strictly meets JECFA’s Acceptable Daily Intake (ADI) standard of 7.5mg/kg body weight. Clinical evaluations indicate that < 0.1% of individuals exhibit sensitivity, which remains well below the global average for synthetic food dyes.

Q: How should bulk quantities be stored to maximize color stability and shelf life?

A: We recommend storing the powder in our original opaque, sealed containers at controlled ambient temperatures of 15°C–25°C, maintaining relative humidity at ≤ 50%. Shielding the product from direct sunlight ensures the shelf life extends to a full 36 months without degradation.

Q: Can this dye be effectively blended with other synthetic colorants for custom shades?

A: Absolutely. Our lemon yellow powder mixes uniformly with Sunset Yellow (E110) to create rich amber tones, and with Brilliant Blue (E133) for vivid green shades. An optimal blending ratio of 1:1 is recommended as a starting point for developing secondary colors.

Q: What is the minimum procurement volume for industrial applications?

A: To support both pilot testing and full-scale commercial runs, our standard volume begins at one 20 kg drum. We also accommodate larger contract orders with staggered delivery schedules to optimize your inventory management.

Q: Do you provide comprehensive documentation for export compliance?

A: Yes, every batch is accompanied by a detailed Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and applicable Kosher/Halal certificates to ensure frictionless customs clearance and regulatory approval in your target markets.

Product Advantages

Advanced Color Exchange and Matrix Integration

Our premium lemon yellow is synthesized utilizing an optimized condensation method and an advanced heavy ammonia-coupling technique. This refined manufacturing process yields a micro-fine powder with exceptional dissolution kinetics. It serves as an essential coloring agent for beverages, hard candies, delicate pastries, clear jellies, ice creams, and pharmaceutical coatings. By instantly transforming the visual profile of the base matrix, it dramatically improves the final appearance and consumer appeal of the food product, ensuring a vibrant, appetizing hue that remains stable throughout the product’s lifecycle.

Unmatched Versatility Across Industrial Applications

Beyond its primary function in nourishing consumables, this water-soluble synthetic pigment exhibits a bright and tender yellow color that is highly sought after across multiple sectors. It is extensively deployed in the formulation of frozen desserts, flavored fermented milk, canned foods, and protective candy coatings. Furthermore, its resilient chemical structure allows it to be utilized for dyeing natural fibers like wool and silk, as well as for manufacturing high-opacity aluminum lakes.

The utility of our tartrazine extends into technical and non-food industries, proving highly effective in the production of specialized coatings, printing inks, extruded plastics, and stationery items. Whether applied as a primary dyeing agent for sensitive medicinal capsules or integrated into complex cosmetic formulations, it delivers consistent, non-bleeding coloration that elevates the perceived value of your manufactured goods.

Product Description

Our industrial-grade tartrazine presents as a remarkably fine, free-flowing crystalline powder with a vivid, luminous lemon-yellow appearance. When handled, the micro-particulates exhibit a smooth, dry texture that resists clumping, ensuring precise volumetric dosing on automated production lines. Upon introduction to aqueous solutions, the powder dissolves instantaneously, transforming clear liquids into brilliant, fluorescent yellow solutions without leaving any gritty residue or suspended particulates.

Manufactured in our highly controlled facility, each batch undergoes a rigorous multi-stage filtration process to eliminate impurities and guarantee a purity level exceeding 98.5%. This meticulous refinement results in a pigment that is completely devoid of off-odors or bitter chemical aftertastes, preserving the original flavor profile of your delicate food and beverage formulations. The exceptionally low moisture content (≤ 1.5%) further prevents microbial degradation during extended storage.

For procurement managers and formulation chemists, this synthetic colorant represents the pinnacle of cost-efficiency and performance reliability. By delivering maximum tinctorial strength at microscopic usage rates, it dramatically reduces inventory footprint and batch costs. Its superior resistance to thermal processing and oxidative stress ensures that the vibrant yellow hue remains locked into the product matrix from the factory floor to the consumer’s table.
