Kefir has established itself in signature ice cream and pastry menus as a benchmark flavor within the “fermented-acid” trend. Its slightly acidic, creamy profile with a distinctive lactic touch makes it an ideal base for ice creams seeking to differentiate themselves from flat sweetness and offer a more complex sensory experience.

But working with kefir in ice cream making is not trivial: its acidity, its fermented milk solids content, and its tendency to generate larger crystals require precise stabilization. This is where Profiber Stab 5 comes in, the stabilizer that makes a reliable formulation possible in both cold and hot processes.

The technical challenge of Kefir ice cream

All ice cream is sustained by a balance between three pillars: the freezing point, the structure of the aqueous phase, and the incorporation of air (overrun). When a fermented ingredient like kefir is introduced, that balance becomes complicated:

• Lactic acidity can destabilize proteins and promote syneresis (whey separation).
• The variable content of non-fat solids alters the cryoscopic point and, therefore, the mouthfeel.
• The absence of correct free water management results in large crystals and a sandy sensation after blast chilling.

The solution involves combining a robust stabilizing system with functional sugars that work on the freezing curve. For this reason, alongside Profiber Stab 5, Dextrose, Inulin, and Maltodextrin are commonly used: Dextrose provides anti-freezing power and adjusts the cryoscopic point; inulin provides body, creaminess, and acts as a functional fiber without adding excessive sweetness; maltodextrin balances total solids and improves texture without displacing the flavor profile.

This trio, well-dosed alongside the stabilizer, is what allows an ice cream with such a particular base as kefir to maintain structure, creaminess, and shelf life in the display case.

Kefir 2.0 by Iván Vázquez

This kefir ice cream formulation has been developed by Iván Vázquez, who continues his collaboration with us this year within the ice cream and sorbet category. His proposal starts from a clear principle: the kefir must be clearly perceived on the palate, without the stabilization technique interfering with its acidic-lactic character. The result is an ice cream with a silky texture, prolonged creaminess in the mouth, and a controlled acidity that refreshes without unbalancing the whole.

“In this Kefir 2.0 recipe, I do something completely different: I directly ferment all the milk and cream in the recipe using kefir grains; the entire dairy system of the ice cream is kefir. This makes the aromatic intensity and complexity much greater and, furthermore, allows for control over the desired level of acidity and fermentation in the ice cream.” Iván Vázquez.

Why is kefir a trend with staying power?

The interest in kefir in ice cream and pastry making is not a passing fad, but part of a broader movement toward “alive” flavors: fermented, acidic, with lactic nuances and a narrative of well-being and digestibility. This trend connects with profiles such as yogurt, buttermilk, or kombucha, and responds to a consumer looking for desserts that are less cloying and have greater aromatic complexity.
For the professional, the challenge is not in the concept—kefir already has recognition and demand—but in the technical execution.

Having a stabilizer like Profiber Stab 5, capable of supporting these more delicate bases without compromising the production flow, is what allows this trend to be consistently translated to the menu.
