Take the guesswork out of food formulation with our powerful Hydrocolloid Usage Calculator. Whether you're creating smooth sauces, sliceable gels, or creamy dairy alternatives, this tool helps you determine the exact hydrocolloid dosage needed for perfect texture—every time.
Hydrocolloids like xanthan gum, agar agar, gelatin, and carrageenan are essential in food science, but precision is critical. Using too much or too little can ruin your recipe. Our calculator simplifies the process, providing accurate measurements tailored to your liquid volume and desired texture.
With just three quick inputs, our calculator gives you precise hydrocolloid amounts:
Enter your liquid volume – in ounces or milliliters.
Choose your hydrocolloid – from gelatin to xanthan to kappa carrageenan.
Select your texture goal – light, medium, or firm.
The result? A reliable measurement, displayed in grams, matched to your chosen hydrocolloid’s functional properties.
Agar Agar – A vegan, plant-based gelling agent used in firm desserts and terrines. Requires boiling to activate.
Xanthan Gum – A cold-soluble thickener ideal for gluten-free baking, sauces, and suspensions.
Guar Gum – Adds viscosity in cold systems; great in dairy-free ice creams and beverages.
Kappa & Iota Carrageenan – Used in dairy and plant-based milks for smooth or gelled textures.
Gelatin – Creates elastic, melt-in-your-mouth gels for puddings, panna cottas, and gummies.
Input Volume
Enter the volume of your recipe liquid (ml or oz).
Select Hydrocolloid
Choose from the list of supported gelling and thickening agents.
Pick Desired Texture
Light: Slight thickening or delicate gels
Medium: Spoonable, soft-set consistency
Firm: Sliced, rigid, or gummy
Get Your Measurement
The calculator provides the exact amount in grams—ready for immediate use.
đź§ No math required. Just smart food science.
Disperse First, Hydrate Second:
Always blend hydrocolloids evenly into your liquid before hydrating. High-speed mixing prevents clumping.
Know the Activation Method:
Cold-soluble: Xanthan, guar
Heat-activated: Agar (85–100°C), gelatin (bloom in cold water, heat to dissolve)
Stick to Suggested Ranges:
Typical usage rates range from 0.1% to 2% depending on the hydrocolloid and desired outcome.
Combine for Custom Textures:
Pairing xanthan with guar or agar with locust bean gum can improve mouthfeel and stability. (Coming soon: [Hydrocolloid Pairing Tool]!)
How much xanthan gum should I use to thicken salad dressing?
Use 0.1% to 0.3% xanthan gum by weight of liquid. Our calculator gives you the exact gram amount based on your volume.
What’s the difference between agar and gelatin?
Agar forms firm, brittle gels and is vegan. Gelatin creates soft, elastic textures and is animal-based.
Can I dissolve agar without boiling?
No. Agar must be heated to at least 85°C (185°F) to activate properly.
What if my recipe turns rubbery?
You’ve likely used too much hydrocolloid. Try a lower dosage using the calculator’s “light” setting and increase gradually.
Use our Hydrocolloid Usage Calculator now to achieve perfect textures in your sauces, jellies, dressings, and plant-based recipes. No more guesswork—just science-backed results.
