Food Ingredients: Safety of Flavors, Colors and Leavening Agents
AI Summary: Ingredients such as food flavors, colors, leavening agents and thickeners should be food-grade, with labels, applicable scope, dosage and testing verified. Natural colors may fade under light and heat, and synthetic colors must also be on the permitted list. Formula development should confirm regulations first, then conduct stability testing.
Procurement Checklist
| Review Item | Selection Point |
|---|---|
| Food-grade marking | Name, batch number and license clear |
| Applicable scope | Permitted food categories differ by ingredient |
| Dosage limits | Follow standards and formula, not intuition |
| Stability | Colors and flavors are affected by processing conditions |
| Storage and shelf life | Sealed, light-protected and moisture-proof |
Procurement, installation and use points
1. Flavors are volatile
They should be sealed and avoid prolonged exposure to high temperatures.
2. Natural does not mean unlimited
It still must comply with standards.
3. Make small samples for color
Color may change after processing and storage.
4. Allergens and sources
Some ingredients require labeling.
FAQ Quick Answers
Are natural colors safer?
Compliant colors can all be used; natural colors may have poorer stability.
Is it better to add more flavor?
Excessive flavor becomes pungent instead.
Do leavening agents lose effectiveness?
Effectiveness decreases after moisture absorption.
How are thickeners used?
According to the formula and dispersion process.
Practical Case
A beverage used natural colors without light exposure testing and faded within a short time. After adjusting the formula and using light-protective packaging, the color became stable.
Questions to Ask the Supplier
- Is the ingredient food-grade?
- Applicable scope and limits?
- Heat and light resistance?
- COA and batch number?
