Hydrocolloids are among the most powerful tools in modern food formulation. They control viscosity, stabilize emulsions, create gels, suspend particles, and improve freeze-thaw stability. Yet one of the most common questions in both professional kitchens and R&D labs is simple:
“How much should I use?”
This reference guide provides practical usage percentages, hydration temperatures, gelling behavior, pH stability, and freeze-thaw performance for the most widely used hydrocolloids in food systems.
All percentages listed are based on total formula weight. Actual performance depends on shear, ionic environment, sugar content, and desired texture.

Ingredient Functional Breakdown
Xanthan Gum
Usage: 0.1–0.5%
Hydration: Fully cold soluble
Function: Thickener and stabilizer
Xanthan gum provides smooth, shear-thinning viscosity. It remains stable across a wide pH range (2–12), making it ideal for acidic sauces, beverages, and dressings. It does not form a true gel but creates stable suspensions and prevents phase separation.
Best for: Salad dressings, sauces, beverage stabilization, gluten-free baking.
Guar Gum
Usage: 0.2–0.8%
Hydration: Cold soluble
Guar produces a soft, rounded viscosity. It hydrates rapidly but is less acid-stable than xanthan. Often used in ice cream systems and baked goods.
Best for: Ice cream, bakery, dairy systems.
Locust Bean Gum (Carob Bean Gum)
Usage: 0.2–1.0%
Hydration: Requires heating above 85°C
Alone, it thickens but does not gel. In combination with carrageenan, it forms strong elastic gels.
Best for: Dairy gels, elastic texture systems.
Sodium Alginate
Usage: 0.5–1.0%
Hydration: Cold soluble
Forms gels when exposed to calcium ions. Used in spherification and restructured foods.
Best for: Molecular gastronomy, encapsulation, controlled release systems.
Agar Agar
Usage: 0.5–2.0%
Hydration: Must dissolve at ~90°C
Sets upon cooling and forms firm, brittle gels. Thermo-reversible.
Best for: Vegan gels, layered desserts, firm applications.
Kappa Carrageenan
Usage: 0.3–1.0%
Hydration: 70–80°C
Forms firm, sliceable gels in the presence of potassium ions.
Best for: Dairy gels, processed cheese systems.
Iota Carrageenan
Usage: 0.3–1.0%
Hydration: 70–80°C
Forms elastic, flexible gels with calcium ions.
Best for: Soft gel desserts, dairy systems.
High Methoxyl Pectin
Usage: 0.5–1.5%
Requires high sugar and acid to gel.
Classic jam and jelly structure.
Low Methoxyl Pectin
Usage: 0.5–1.5%
Calcium activated.
Allows low-sugar formulations.
Konjac Gum
Usage: 0.2–1.0%
Strong synergy with carrageenan.
Produces elastic gels.
Synergy Matrix
| Combination | Result |
|---|---|
| Xanthan + Guar | Increased viscosity |
| Locust Bean + Carrageenan | Elastic gel |
| Alginate + Calcium | Instant gel |
| Konjac + Carrageenan | Strong thermo-reversible gel |

Hydrocolloid Usage Chart FAQs
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 (about 240g), that’s roughly 0.25–0.7g. Start low and increase gradually to avoid “snotty” texture.
What percentage of agar agar is needed to make a firm gel?
Agar typically sets into a firm gel around 0.8–1.5%. For a softer gel, try 0.5–0.8%. Agar must be brought close to a boil to fully dissolve before it will set cleanly.
Why isn’t my carrageenan setting?
Carrageenan needs proper heat hydration (about 70–80°C) and the right ions: potassium supports kappa for firm gels and calcium supports iota for elastic gels. Under-heating, low solids, or insufficient ions can prevent a strong set.
Which hydrocolloid makes the strongest gel?
For firm, sliceable gels, agar and kappa carrageenan are among the strongest at comparable use levels. “Strongest” depends on whether you mean firmness, elasticity, or heat reversibility.
What’s the difference between iota and kappa carrageenan?
Kappa forms firmer, more brittle gels (especially with potassium). Iota forms softer, more elastic gels (especially with calcium) and tends to have better freeze-thaw performance.
Do xanthan and guar gum work well together?
Yes. Xanthan + guar often gives a fuller, more stable viscosity than either alone. It’s a common pairing for sauces, dressings, and gluten-free baking where you want body without gelation.
Why did my xanthan gum clump?
Xanthan can “fish-eye” when added directly to water. To prevent clumping, disperse it first in oil, sugar, or another dry ingredient, then blend with strong shear (immersion blender or high-speed blender).
What hydrocolloid is best for acidic foods like dressings or hot sauce?
Xanthan gum is a top choice for acidic systems because it stays stable across a wide pH range. It thickens without needing heat and helps keep spices and particles suspended.
Can I freeze products made with hydrocolloids?
Some perform better than others. Xanthan and low methoxyl pectin generally do well. Agar gels often weep or lose texture after freezing. Freeze-thaw performance also depends on sugar, fat, and total solids.
How do I choose between high-methoxyl and low-methoxyl pectin?
High-methoxyl pectin gels with high sugar + acid (classic jam/jelly). Low-methoxyl pectin gels with calcium and can work in low-sugar or no-sugar-added systems.
What’s the easiest hydrocolloid for beginners?
Xanthan gum is often the easiest place to start: it hydrates cold, is forgiving, and improves stability in many recipes. Use small amounts and blend well.
Are the percentages listed based on total recipe weight?
Yes. The ranges on this page are percent of total formula weight, not percent of water phase. For more precision, weigh your full formula and calculate hydrocolloid dosage from that total.
