Product Overview
Inorganic food-grade pigments are used for color design in food formulations. Different varieties vary in chemical composition, hue, and dispersibility; therefore, when selecting a pigment, it is essential to specify the exact name, specifications, and intended use. One should not rely solely on the terms “food-grade” or “inorganic pigment” to determine whether a pigment is suitable for a particular type of food.
Product applications should be evaluated in consideration of the target color, formulation, and processing conditions. For specific product types, supply specifications, and application information, refer to the product label, specifications, and batch test reports.
Features
Select a Model Based on Your Needs:Select based on the specific variety’s color, particle characteristics, and formulation requirements.
Scattered Attention:For products in which coloring is achieved through particle dispersion, uniformity should be verified through mixing tests.
Process Adaptation:Verify the effectiveness of the application by considering processing temperature, acid-base conditions, and storage environment.
Data Verification:Before use, verify the product's identity, specifications, and corresponding application requirements.
App Recommendations
The following outlines the evaluation criteria for formulation development; this does not imply that all edible inorganic pigments are approved for use in these applications. The suitability of a specific pigment for the target food product should be confirmed before conducting tests.
| Application Evaluation Areas | Coloring Requirements | Test Focus Areas |
|---|---|---|
| Food Surface Coloring | Forming the desired color on the surface of approved foods | Dispersion Uniformity, Adhesion, and Color Changes After Friction |
| Internal Coloring in the Formula | Ensure that the approved food system has a uniform color | Compatibility with the formulation, granularity, and color differences after processing |
| Blended Color Scheme | Adjust the color tone by combining suitable ingredients | Suitability, Mixing Uniformity, and Storage Stability of Each Component |
Technical Specifications
Use and Storage
Before use, verify the approved scope of use, usage levels, and relevant restrictions for the specific variety in the target food product. Different varieties cannot be substituted for one another on a one-to-one basis, and the supplier’s application recommendations cannot replace the applicable standards.
Store in a sealed container, protected from light and moisture, as indicated on the product label. After opening, reseal the container promptly, and keep the dispensing tools clean and dry to prevent moisture absorption and cross-contamination. Refer to the product label and specifications for storage conditions and shelf life.
Frequently Asked Questions
Q: Can inorganic food colorings be used in all foods?
No. The specific variety must be clearly identified, and its scope of application and restrictions in the target food product must be verified; the name of the product category cannot be used as a substitute for item-by-item verification.
Q: How do I choose the right product specifications?
Based on the target shade, formulation, particle characteristics, and processing conditions, and in conjunction with product data, conduct small-scale trials to verify the coloring effect and process compatibility.
Q: Why do color spots or uneven coloring occur?
For decentralized coloring systems, check whether the powders have agglomerated, whether they are thoroughly mixed, and whether the feeding sequence and formulation are appropriate. The pre-dispersion and mixing methods can be optimized based on the supplier’s process recommendations.
Q: Can different varieties be substituted directly?
Direct substitution is not recommended. Different varieties may vary in terms of their scope of application, color tones, and formulation characteristics, so it is necessary to reconfirm their suitability and the appropriate addition ratio.
Q: How do I determine the amount to add?
First, review the usage requirements for the specific product; then, conduct small-scale trials to determine the optimal addition ratio to achieve the desired color, and verify the results after processing and storage.
Q: What information do I need to confirm before making a purchase?
We recommend verifying the specific product name, specifications, batch test reports, labels, and instructions for use, while also checking the relevant requirements for the target food product and the region where it will be sold.
