Quick Answer: Hydrocolloid Usage Chart
Hydrocolloid Comparison Table
| Ingredient | Typical Use % | Hydration / Activation | Sets? | Texture Profile | pH Stability | Freeze-Thaw |
|---|---|---|---|---|---|---|
| Xanthan Gum | 0.10–0.50% | Cold soluble (high shear helps) | No gel | Smooth, shear-thinning viscosity | 2–12 | Excellent |
| Guar Gum | 0.20–0.80% | Cold soluble (disperse to avoid clumps) | No gel | Soft thickness / body | 4–10 | Moderate |
| Locust Bean Gum | 0.20–1.00% | Heat to ~85°C+ to fully hydrate | No gel alone | Creamy body; synergistic in gels | 4–10 | Good |
| Sodium Alginate | 0.50–1.00% | Cold soluble; gels with calcium ions | With calcium | Elastic gel / encapsulation | 4–10 | Moderate |
| Agar Agar | 0.50–2.00% | Dissolve near boil (~90°C) | Sets cold | Firm, brittle gel (thermo-reversible) | 4–10 | Poor |
| Kappa Carrageenan | 0.30–1.00% | Heat 70–80°C; potassium helps firm gels | Sets hot | Firm / sliceable gel | 4–9 | Moderate |
| Iota Carrageenan | 0.30–1.00% | Heat 70–80°C; calcium helps elastic gels | Sets hot | Elastic / flexible gel | 4–9 | Good |
| High Methoxyl Pectin | 0.50–1.50% | Heat 80–90°C; needs sugar + acid to gel | Sugar + acid | Classic jam / jelly gel | 2.8–3.5 ideal | Good |
| Low Methoxyl Pectin | 0.50–1.50% | Heat 80–90°C; gels with calcium (low sugar OK) | With calcium | Flexible gel / clean bite | 2–6 | Excellent |
| Konjac Gum | 0.20–1.00% | Heat 85°C+; strong synergy with carrageenan | Synergistic | Strong elastic gel | 4–10 | Good |
| Sunflower Lecithin | 0.20–1.00% | Cold soluble (blend to disperse) | No gel | Emulsifier / foam support | 2–10 | N/A |
How to Use This Chart in 60 Seconds
1) Pick the job
- Thicken a sauce or drink → xanthan / guar
- Set a gel → agar / carrageenan / pectin / alginate
- Stabilize emulsion/foam → lecithin + gum
2) Match your conditions
- Acidic? choose xanthan; HM pectin needs acid (2.8–3.5 ideal)
- Low sugar? LM pectin (with calcium) beats HM pectin
- Freeze/thaw? xanthan + LM pectin tend to hold best
3) Avoid the #1 failure mode: clumping
Disperse powders before hydrating. Easy methods: blend into sugar/salt first, whisk into oil first, or use high shear (immersion blender).
Best Picks by Goal
For sauces, dressings, beverages (no heat)
Start here: Xanthan Gum
- Works cold
- Wide pH stability
- Excellent suspension
For ice cream / dairy body and scoopability
Start here: Guar Gum + Locust Bean Gum
- Creamier body
- Helps reduce iciness
- Great with heat processing
For firm, clean-cut gels (vegan + thermo-reversible)
Start here: Agar Agar
- Boil to dissolve (~90°C)
- Sets on cooling
- Firm, brittle bite
For elastic gels + dairy systems
Start here: Iota Carrageenan (elastic) or Kappa Carrageenan (firm)
- Hydrate ~70–80°C
- Iota = flexible; Kappa = sliceable
- Ion-dependent performance
Need “which one should I use?” fast?
Use the interactive selector to narrow by goal (thickening vs gelling), processing temperature, sugar, and pH.
Synergy Matrix
| Combination | Result |
|---|---|
| Xanthan + Guar | Increased viscosity / improved mouthfeel |
| Locust Bean + Carrageenan | Elastic gel / stronger structure |
| Alginate + Calcium | Instant gel / encapsulation |
| Konjac + Carrageenan | Strong thermo-reversible gel |
Hydrocolloid Usage Chart FAQs
Are the percentages listed based on total recipe weight?
Yes. The ranges on this page are percent of total formula weight, not percent of the water phase.
How much xanthan gum should I use per cup of liquid?
Typical usage is 0.1–0.3% by total weight. For 1 cup of liquid (~240g), that’s roughly 0.25–0.7g. Start low and increase gradually.
Why did my xanthan gum clump?
Xanthan can “fish-eye” when added directly to water. Disperse it first in oil or dry ingredients, then blend with strong shear.
What percentage of agar agar is needed to make a firm gel?
Agar typically sets firm around 0.8–1.5%. For a softer gel, try 0.5–0.8%. It must dissolve near boiling to set cleanly.
Why isn’t my carrageenan setting?
Carrageenan needs proper heat hydration (70–80°C) and the right ions: potassium supports kappa (firm) and calcium supports iota (elastic).
How do I choose between high-methoxyl and low-methoxyl pectin?
High-methoxyl pectin gels with high sugar + acid. Low-methoxyl pectin gels with calcium and can work in low-sugar systems.
