Have you just taken your Gelato out of the freezer, only to see those beautiful swirls soften within minutes, lose their shape, release water, and no longer maintain their original structure?
Don't be too quick to assume that the only problem is that “the freezer isn't cold enough.”
In reality, Gelato's resistance to melting is the result of an entire system: water content, sugar, total solids, fat, PAC/POD, Stabilizer, pasteurization, rapid freezing, and storage conditions.
A recipe can produce Gelato that is very soft and easy to scoop but melts extremely quickly. Conversely, Gelato may hold its shape well but be too hard, lack smoothness, and fail to deliver the desired eating experience.
FABBRI 1905 also develops its Base systems based on various formulation factors, including milk powder, fat, protein, fiber, Stabilizer, Emulsifier, and different types of sugars.
In this article, IKEM will analyze the 9 most common causes of fast-melting Gelato and explore practical approaches to improving each one.
This is one of the most important causes.
Gelato inevitably contains water. However, the key question is how much of that water becomes ice and how much remains unfrozen.
If the recipe contains:
Too much water
Low total solids
Insufficient sugar to control the freezing point
A structure that does not have enough water-binding capacity
Gelato will tend to become soft quickly when exposed to ambient temperatures.
You should not simply “reduce the water.”
Instead, evaluate the recipe as a whole:
Water → Sugar → Total Solids → PAC → Stabilizer → Fat/Protein
The goal is to create a balanced structure in which water is properly controlled rather than existing excessively as free water.
Many beginners think:
“Sugar is only used to make Gelato sweet.”
This is an incomplete understanding.
In Gelato, sugar also affects the freezing point and the amount of water that freezes, directly influencing softness, scoopability, and melting rate.
Different types of sugar do not have the same effect.
For example, a recipe may contain:
Sucrose
Dextrose
Glucose syrup/glucose powder
Fructose
Maltodextrin
Other carbohydrates
FABBRI also uses different types of sugars and sweetening ingredients in its Base systems, depending on the purpose and formulation.
Gelato may become:
PAC too high → too soft → melts quickly
or:
PAC too low → too hard → difficult to scoop
Therefore, adding more sugar does not automatically make Gelato better.
What matters is selecting the right type of sugar and using it at the appropriate ratio.
PAC is a parameter commonly used in Gelato technology to evaluate the antifreeze effect of a formulation and its influence on the freezing point.
A recipe with high PAC tends to maintain a larger unfrozen phase at serving temperature, making Gelato softer and easier to scoop.
However, if PAC is too high, the result may be:
Gelato that is too soft
Gelato swirls that quickly collapse
Gelato that melts easily at room temperature
Difficulty creating attractive shapes in the display case
A short serving window outside the freezer
Special attention should be paid to ingredients with naturally high sugar content, such as fruit, puree, chocolate, sauces, syrups, and flavor pastes. These ingredients can significantly change the sugar balance of a recipe.
Do not calculate only the amount of added sucrose.
Consider the total amount of actual sugars contributed by all ingredients.
If PAC is closely related to the antifreeze effect, POD is commonly used to evaluate relative sweetness.
Two recipes may contain similar amounts of sugar but still have different:
Sweetness levels
Softness
Shape retention
This happens because different sugars have different sweetness levels and different effects on the freezing point.
Therefore, Gelato balancing should not be based simply on the question:
“How many grams of sugar do I need?”
Instead, ask:
“Which type of sugar do I need, and at what ratio, to achieve the appropriate sweetness and PAC/POD balance?”
This is precisely why professional Gelato formulation requires calculation rather than relying entirely on trial and error.
This is a commonly overlooked cause.
Total Solids play an important role in creating body, mouthfeel, and structure in Gelato.
If the recipe contains too much water but too little:
Milk powder
Protein
Sugar
Fat
Fiber
Other solid ingredients
the Gelato structure will be weak.
When exposed to serving conditions, that structure can become unstable and melt more quickly.
FABBRI states that its Base systems are selected based on the composition and quality of various factors such as milk powder, fat, protein, fiber, Stabilizers, Emulsifiers, and sugars.
Instead of simply increasing the fat content, evaluate the total solids of the entire recipe.
A great Gelato does not necessarily need a high fat content.
What matters is creating a balanced structure between water – sugar – protein – fat – total solids – Stabilizer.
Stabilizer plays an important role in water management, structural support, and limiting the development of ice crystals.
However, it is also an ingredient that can easily be misused.
May result in:
Weak structure
Poor water control
Gelato quickly losing its shape
Ice crystals developing more easily during storage
On the other hand, excessive Stabilizer may cause:
Gelato to become too thick
A gummy mouthfeel
A sticky sensation
Loss of a clean eating experience
Therefore:
Stabilizer is not a “cure-all” for fast-melting Gelato.
If the recipe is already incorrect in terms of sugar, water, or total solids, simply increasing Stabilizer may not solve the problem.
Studies on the melting behavior of frozen desserts also indicate that Stabilizers can contribute to maintaining structure during melting, but their effectiveness depends on the type of Stabilizer and the overall formulation.
This is a production technology factor, not simply a formulation issue.
After Gelato leaves the batch freezer, its structure continues to change.
If freezing/hardening takes too long, ice crystals have more time to grow.
The result may be:
Larger ice crystals
Less smooth texture
Weaker structure
Gelato that loses its shape more easily
Faster melting and poorer appearance when exposed to higher temperatures
Therefore, the batch freezer and blast freezer should not be overlooked.
Rapid freezing helps reduce the time available for large ice crystals to form and supports the preservation of the product's structure.
Some specialized blast freezers are designed to rapidly lower the core temperature of Gelato, helping promote the formation of smaller ice crystals.
Even a well-formulated recipe can experience problems if the storage equipment is not suitable.
Common causes include:
The freezer is too warm
Frequent temperature fluctuations
The door is opened too often
The freezer is overloaded
Uneven cold-air circulation
Gelato is placed in a warmer area of the freezer
The equipment has not reached a stable temperature before the product is loaded
In particular, it is important to distinguish between:
Storage Temperature ≠ Serving Temperature
Gelato is designed to be served in a softer state than conventional industrial ice cream.
Therefore, the recipe should be balanced according to the actual serving temperature of the shop, rather than simply relying on the temperature displayed by a particular freezer.
Even when the recipe and equipment are both good, Gelato can still melt quickly if the operating process is not consistent.
Some common mistakes include:
Gelato continuously absorbs heat from the environment → the ice phase begins to melt → the structure becomes weaker.
Repeated temperature changes can weaken the Gelato structure and accelerate changes in ice crystal structure.
Exposure to air and temperature fluctuations can negatively affect the surface and structure.
After leaving the batch freezer, Gelato needs an appropriate subsequent cooling/hardening process before being placed on display.
Creating multiple grooves, increasing the exposed surface area, and leaving the structure uneven can also make it more difficult to maintain an attractive appearance.
Instead of addressing just one cause, evaluate your Gelato across these 7 key areas:
