How This Guide Works
Selecting a natural color is not a one-step decision. Each food application has its own combination of pH, processing temperature, packaging, and shelf life expectations — and the right colorant choice changes accordingly.
This guide is organized by application category. For each category, you will find:
- Typical processing context (pH range, heat profile, packaging type, shelf life)
- Recommended natural colorants for each color requirement
- Colorants to use with caution
- Colorants to avoid — and why
- Link to the relevant Binmei application page for product-specific datasheets
If your product spans multiple categories or has unusual specifications, the bottom section of this page includes a direct line to our technical team for application-specific guidance.
Natural Colors for Beverages
Beverages: Soft Drinks, Juices, Sports Drinks, Functional Beverages
Beverages are one of the most challenging applications for natural colors. Three factors compound: low pH degrades anthocyanin colors slowly over shelf life, hot-fill processing accelerates heat-sensitive colorants, and transparent packaging exposes the product to continuous light.
Color Recommendations by Target Shade
| Target Color | Recommended Colorant | Why |
|---|---|---|
| Blue / Teal | Butterfly Pea Flower Extract | 97% retention at pH 3, 80°C. Color shifts from purple toward blue as pH decreases — ideal for acidic beverages. |
| Red / Berry | Aronia Extract, Black Carrot Extract | 85% heat retention at pH 3. Anthocyanin-stable at typical beverage pH. Black Carrot Extract provides slightly cleaner red tone; Aronia Extract offers deeper berry hue. |
| Pink / Magenta | Aronia Extract (lower dosage), Black Carrot Extract (lower dosage) | Anthocyanin-stable at low pH. For anthocyanin reds in transparent packaging, consider light-protective additives. |
| Yellow / Orange | Sea Buckthorn Extract | Carotenoid pigment is pH-insensitive. Acceptable heat retention at typical beverage processing temperatures. |
| Purple | Aronia Extract, Black Carrot Extract blends | Anthocyanin reds at borderline pH can shift purple. Custom blending available for targeted purple shade. |
✓ Strongly Recommended
- Butterfly Pea Flower Extract (purple/violet at low pH; blue with pH-adjusted pre-mix)
- Aronia Extract (red, hot-fill)
- Black Carrot Extract (red, versatile)
- Sea Buckthorn Extract (yellow)
⚠ Use With Caution
× Not Recommended
- Spirulina Extract — pH collapse below 4.0
- Beet Extract — heat-sensitive

Natural Colors for Dairy & Yogurt
Dairy & Yogurt: Flavored Milk, Drinking Yogurt, Set Yogurt, Dairy Desserts
Dairy is more forgiving than beverages for natural colors. Opaque packaging eliminates the light stability concern. Pasteurization is short-duration. The main variable is the pH range: yogurt and cultured products are acidic, while plain milk and dairy beverages are near-neutral.
Color Recommendations by Dairy Type
| Dairy Product | Target Color | Recommended Colorant |
|---|---|---|
| Yogurt (pH 4.0-4.5) | Red / Pink | Beet Extract, Black Carrot Extract, Aronia Extract — all stable at this pH |
| Yogurt (pH 4.0-4.5) | Blue / Purple | Butterfly Pea Flower Extract — ideal pH match. Spirulina not recommended below pH 4.2. |
| Flavored Milk (pH 6.5-6.8) | Blue | Spirulina Extract — pH optimal at this range |
| Flavored Milk (pH 6.5-6.8) | Red / Pink | Beet Extract — betanin stable at neutral pH in low-heat dairy. Anthocyanin reds shift color at this pH. |
| Drinking Yogurt | Yellow / Orange | Sea Buckthorn Extract — pH-insensitive, stable in dairy |
| Dairy Dessert | Any | Match colorant to dessert pH. Most options viable due to opaque packaging. |
✓ Strongly Recommended
- Spirulina (blue, neutral-pH dairy)
- Beet Extract (red, all dairy)
- Sea Buckthorn Extract (yellow, all dairy)
- Butterfly Pea Flower Extract (purple/violet at yogurt pH 4.2)
⚠ Use With Caution
- Spirulina in yogurt — check pH
× Not Recommended
- None across all dairy categories — dairy is forgiving
Natural Colors for Ice Cream & Frozen Desserts
Ice Cream & Frozen Desserts: Premium Ice Cream, Sorbet, Frozen Yogurt, Gelato
Ice cream is one of the most natural-color-friendly applications. Pasteurization is short. Storage is frozen. Packaging is opaque. The main consideration is pH: traditional ice cream is near-neutral (favoring Spirulina, Beet Extract), while fruit sorbets are acidic (favoring Butterfly Pea Flower Extract, anthocyanin reds).
Color Recommendations by Product Type
| Product Type | pH Range | Recommended for Blue | Recommended for Red | Recommended for Yellow |
|---|---|---|---|---|
| Premium Ice Cream | 6.0-7.0 | Spirulina Extract | Beet Extract, Black Carrot Extract | Sea Buckthorn Extract |
| Fruit Sorbet | 3.0-4.0 | Butterfly Pea Flower Extract | Aronia Extract, Black Carrot Extract | Sea Buckthorn Extract |
| Frozen Yogurt | 4.0-4.5 | Butterfly Pea Flower Extract | Beet Extract, Black Carrot Extract, Aronia Extract | Sea Buckthorn Extract |
| Gelato | 6.0-6.8 | Spirulina Extract | Beet Extract, Black Carrot Extract | Sea Buckthorn Extract |
Why Spirulina Excels in Ice Cream
Spirulina Extract is frequently the first choice for blue ice cream. Three reasons: ice cream pH (6-7) is in Spirulina's optimal range; pasteurization heat exposure is short (typically minutes, not hours); and frozen storage eliminates the temperature degradation pathway. The result is a vivid blue that holds color through standard shelf life.
Natural Colors for Bakery
Bakery: Cakes, Cookies, Frosting, Macarons, Bread, Pastry
Bakery is the most demanding application for natural colors. High baking temperatures destroy heat-sensitive colorants. Near-neutral dough pH causes anthocyanin reds to shift color. For frosting and finishes added after baking, the constraints are reduced significantly.
Bakery Sub-Category Recommendations
| Bakery Product | Heat Exposure | Color Recommendations |
|---|---|---|
| Frosting / Buttercream |
None (cold) | All colorants viable. Match to frosting pH. Butterfly Pea Flower Extract for blue, Beet Extract for red/pink, Sea Buckthorn Extract for yellow. |
| Cake Batter |
Heat-sensitive | Butterfly Pea Flower Extract for blue/purple (heat-stable). Aronia Extract, Black Carrot Extract for red if dough pH adjusted below 5.0. Avoid Spirulina, Beet Extract. |
| Macarons |
Heat-moderate | Butterfly Pea Flower Extract for blue. Aronia Extract, Black Carrot Extract for red. Beet Extract possible if baking time minimized. |
| Cookies |
Heat-sensitive | Butterfly Pea Flower Extract for blue. Black Carrot Extract for red (better heat tolerance than Aronia Extract). Sea Buckthorn Extract for yellow. |
| Bread |
Highly heat-stressing | Limited natural color options. Butterfly Pea Flower Extract is most reliable for blue. For red, color loss should be expected; consider post-baking application. |
✓ Strongly Recommended
- Butterfly Pea Flower Extract (blue, all bakery)
- Aronia Extract, Black Carrot Extract (red, at low dough pH)
- Sea Buckthorn Extract (yellow, all bakery)
⚠ Use With Caution
× Not Recommended
- Spirulina (heat-sensitive)
- Beet Extract (heat-sensitive)
Natural Colors for Candy & Confectionery
Candy & Confectionery: Hard Candy, Gummies, Marshmallows, Chocolate, Coated Confections
Confectionery is naturally aligned with anthocyanin colors due to acidic pH. The main challenge is the combination of high cook temperatures (especially hard candy) and long shelf life under transparent packaging. Selection trades off heat tolerance against light stability.
Confectionery Sub-Category Recommendations
| Confectionery Product | Cook Temp | Color Recommendations |
|---|---|---|
| Gummies |
70-90°C | Butterfly Pea Flower Extract for purple/violet (blue requires pH-adjusted color pre-mix). Aronia Extract, Black Carrot Extract for red. All anthocyanin colors are highly stable in this pH range. |
| Hard Candy |
140-170°C | Butterfly Pea Flower Extract for purple/violet at ambient pH; blue only with pH-adjusted color pre-mix. Black Carrot Extract for red (best heat tolerance among anthocyanins). |
| Marshmallows |
110-130°C | Butterfly Pea Flower Extract for blue (pH range delivers true blue). Beet Extract if cooled rapidly. Anthocyanin reds may shift color at this pH. |
| Coated Confections |
Cold | All colorants viable in coatings. Match to coating pH. |
Natural Colors for Dietary Supplements & Nutraceuticals
Dietary Supplements: Gummies, Tablets, Capsules, Functional Powders, Protein Drinks
Supplements are versatile applications because processing conditions are typically gentle and packaging is usually opaque. The main differentiator is the form factor: gummies behave like confectionery (acidic pH, sugar-based matrix), while tablets and capsules behave like dry powder applications.
Supplement Form Factor Recommendations
| Supplement Form | Application Context | Recommended Colorants |
|---|---|---|
| Gummies / Soft Chews | pH 3.0-3.5, low-heat cook | Butterfly Pea Flower Extract (blue), Aronia Extract, Black Carrot Extract (red). Same as confectionery gummies. |
| Tablets / Caplets | Dry compression, no heat | All colorants suitable. Spirulina, Beet Extract, Sea Buckthorn Extract commonly used. Anthocyanin powders also work. |
| Capsules | Filled dry powder, no heat | All colorants suitable for capsule fill or shell coloring. |
| Functional Powders | Reconstituted in water/milk by consumer | Match to expected end-use pH. Spirulina popular for blue/teal smoothie powders; Beet Extract for red protein powders; Sea Buckthorn Extract for orange. |
| Protein Drinks / RTD | pH 6.5-7.0, neutral; heat-treated | Spirulina (blue), Beet Extract (red), Sea Buckthorn Extract (yellow). Anthocyanin reds not recommended at this pH. |
