Maltodextrin in Gelato — The Bulking Agent (PAC 21, POD 9.5)
Table of contents
Maltodextrin is the pre-sugar end of the starch-hydrolysis spectrum — DE 19 or below, almost entirely long-chain dextrins. PAC about 21, POD about 10 per 100 g. It is the gelataio's tool for raising Total Solids with little added sweetness or freezing-point depression. Used mostly in low-sugar gelato lines, vegan formulations missing dairy solids, and recipes where the body feels thin but PAC/POD are already at target.
What Maltodextrin Is
Maltodextrin is starch (corn, wheat, tapioca, potato) that has been hydrolyzed only slightly — DE 3 to DE 19 typically. The result is a mixture of dextrins (chains of 4 to 20+ glucose units) plus small amounts of free glucose and maltose.
Sold as a fine white powder. Tasteless or barely sweet. Dissolves cleanly in water. Approved as a food additive in essentially every regulatory framework worldwide. Cheap (~€2–4/kg).
In ice cream and gelato, maltodextrin is officially a sugar but functionally a bulk solid. Its low sweetness and low PAC make it useful precisely where you want little of either.
The Pure-Bulk Role
Most sugars trade sweetness for PAC or vice versa. Maltodextrin adds mostly bulk, with a little of each. Values are from the app's ingredient table, per 100 g of powder as sold:
| Property | Maltodextrin (DE under 20) |
|---|---|
| PAC | 21 (22 on dry matter) |
| POD | 9.5 (barely sweet) |
| Total Solids | 95% (slight moisture) |
| Effect on freezing point | Small, about a fifth of sucrose |
| Effect on perceived sweetness | Negligible |
| Effect on body and viscosity | Significant |
That last row is the whole point: maltodextrin adds body, viscosity, and Total Solids to a recipe while moving the other balancing parameters only a little.
Quick reference. Maltodextrin: PAC 21 · POD 9.5 · TS 95% (per 100 g as sold) · price about €2 to 4/kg. Use 20 to 60 g per kg of mix to raise Total Solids with little effect on POD and a PAC shift of only 4 to 13 points.
Use Cases in Gelato
1. Low-sugar / diabetic-friendly recipes. When you reduce sucrose to lower POD, your Total Solids drops too. Add maltodextrin to bring TS back into the 36–42% range with little added sweetness or PAC.
2. Vegan gelato without dairy MSNF. Removing dairy means losing the 8–12% MSNF that contributes significantly to Total Solids and body. Maltodextrin (often combined with inulin) replaces some of that body.
3. Sorbets needing more body. Some fruit sorbets feel thin or watery — adding 30–50 g of maltodextrin per kg adds substance while moving sweetness and freezing-point depression only a little (6 to 11 PAC points).
4. Rebalancing mistakes. Made a recipe with PAC and POD on target but Total Solids too low? Maltodextrin fixes it while barely moving the other parameters. The "correction sugar."
How Much to Use
| Recipe type | Maltodextrin (g per 1000 g mix) | Reason |
|---|---|---|
| Low-sugar fior di latte | 30–50 g | Replace TS lost from reduced sucrose |
| Vegan gelato | 30–60 g | Replace MSNF body |
| Thin sorbet | 20–40 g | Add body without sweetness |
| Standard pro gelato | 0–20 g | Optional small adjustment |
Above 60 g per kg, the texture starts feeling slightly mealy or "papery" — fine for some applications, undesirable for delicate flavors.
