A team of INTA Castelar Food Institute has developed some mozzarella chips These products concentrate the nutrients of milk in a light, crunchy, and long-lasting format. They are a food that doesn't require refrigeration, can be taken virtually anywhere, and are designed to meet real needs for access to quality protein.
This new cheese snack, still in the pre-launch phase, offers high nutritional value, ease of transport and long shelf lifeThe technology is ready for transfer to industry, and INTA highlights its potential for Strengthening school meals and reaching areas where maintaining the cold chain is difficult.
A mozzarella snack designed for those lacking protein.
The idea behind these mozzarella chips It arose from a specific query of milk sectorHe was interested in creating a product that could be shipped to areas with limited access to protein-rich foods. The goal was to design a cheese that was easy to distribute, had a stable shelf life, and did not require potable water for consumption—a clear difference from other alternatives such as powdered milk.
According to the researchers involved, the initial approach was clear: to obtain a practical, healthy and stable foodwhich retains the nutritional value of the milk without the need for refrigeration or prior preparation. Hence the choice of mozzarella, a cheese widely used by the dairy industry, available in large volumes, and with characteristics suitable for this type of process.
The development is also framed within the global trend towards healthier snacksCompared to ultra-processed options with added sugars and refined flours, these chips are presented as an alternative based solely on cheese, with high protein content and no carbohydrates.
Experts emphasize that the project not only seeks to open a new product category, but also to respond to specific social needsespecially in childhood and adolescence. That is why the focus has been placed on school settings and in rural or hard-to-reach areas.
INTA emphasizes that the collaboration with private sector It was key to guiding development towards a technologically viable and potentially scalable product, preventing it from remaining a simple laboratory test without continuity in the industry.
How freeze-dried mozzarella chips are made
The basis of these chips is a low moisture, export quality mozzarellaFrom this cheese, a controlled process is followed that begins with slicing and continues with freezing, an essential preliminary step to apply the freeze-drying technique.
La Freeze-drying is a dehydration process at low temperature. This process allows water to be removed from the food without subjecting it to heat. Because high temperatures are not involved, the nutrient profile and original flavor of the mozzarella are preserved much more faithfully, resulting in a dry, light, and crispy cheese.
The process can be summarized in three stages: first, the cheese is cut into thin slices; then it is frozen to stabilize the product's structure; and finally, it is vacuum-sealed to extract the water in the form of steam. The result is compact, stable, and ready-to-eat cheese chipswithout the need for refrigeration or rehydration.
Since it is a product 100% cheese, without preservatives or additivesThe ingredient list is extremely short, which is unusual in the snack category. Stability is achieved precisely through reduced water activity and drying technology, not by adding extra substances.
The toasted, crispy texture and small disc format make it easy to use both as a direct snack and in other preparations, for example, accompanying saladssoups or pasta dishes in those countries or regions where these types of products are sold.
Nutritional value: 20 grams is equivalent to a glass of milk
One of the aspects that researchers highlight most is the nutrient concentrationA standard serving, consisting of about 12 cheese discs (around 20 grams each), provides approximately the same amount of proteins and fats than a glass of milkThis makes chips an interesting option when looking to improve your intake of dairy protein.
Since they do not require water for consumption, these chips offer a clear advantage over the milk powder in contexts where access to safe drinking water is limited. Simply open the package and eat them directly, without any prior preparation or utensils.
The product is positioned within the so-called healthy snacksbecause it contains no added sugars, flours, or starches. Its nutritional profile focuses on high-biological-value proteins, fats naturally present in cheese, and vitamins and minerals found in the original milk.
Among the micronutrients, the minerals typical of dairy products stand out, such as Calciumas well as fat-soluble vitamins that are particularly well preserved when aggressive heat treatments are not applied. The use of good quality mozzarella as a raw material also helps to ensure a consistent nutritional profile.
Experts point out that, despite its snack format, it is a nutrient-dense foodTherefore, it can play a relevant role in diets where protein or dairy intake is insufficient, always integrated into a balanced eating pattern.
Applications in school feeding and vulnerable contexts
Beyond its potential presence in supermarkets, the main purpose of this development is strengthen school feeding programsespecially in areas where maintaining the cold chain poses a logistical or economic challenge. The idea is to bring the benefits of milk to children even in remote regions or those with limited infrastructure.
In situations where it is difficult to transport and preserve liquid milk, yogurt, or other fresh dairy products, these stable and light mozzarella chips They can be an interesting alternative. They don't require refrigeration, have a long shelf life, and can be distributed relatively easily in schools or community kitchens.
The fact that the snack is ready to eat It also simplifies its use in environments where there is no equipped kitchen or where food preparation time is limited. Simply divide small portions to ensure a significant intake of protein and other nutrients found in milk.
The researchers in charge of the development emphasize that behind the project there is not only technological innovation, but also a clear social motivation: improve access to quality food for the child population. The product's stability allows for long-term shipping planning and reduces the risk of losses due to storage problems.
Furthermore, the chips can be integrated into different food distribution strategies, either as a complement within a complete school menu or as nutritional reinforcement in specific programs aimed at rural areas or isolated communities.
A product aligned with the healthy snacking trend
In recent years, interest in healthier snacking alternativesBoth in Europe and in other markets, consumers are looking for options with less sugar and fewer additives, but that are still practical and appealing for everyday life, from work to sports.
In this context, freeze-dried mozzarella chips They fall into the category of high-protein snacks, with no added carbohydrates and a very short ingredient list. They are not simply savory "treats," but a food based entirely on cheese, with the nutritional value associated with the milk from which it is sourced.
Their small disc format and crispy texture make them suitable for consumption both on school environments This is beneficial for athletes or people who need an extra boost of protein mid-morning or mid-afternoon. Furthermore, its gluten-free and starch-free nature broadens the range of people who can incorporate it into their diet.
Their portability, lack of need for refrigeration, and ease of consumption also make them attractive to trips, excursions or outdoor activitieswhere carrying fresh dairy products isn't always practical. At the same time, their status as concentrated dairy products suggests consuming them in moderation as part of a balanced diet.
Although the development has taken place in Argentina, food industry experts point out that a product with these characteristics could have good reception in European markets accustomed to mozzarella and increasingly interested in high-protein snacks.
Project status and possibilities for the dairy industry
At this moment, the mozzarella chips They are produced on a small scale, in a phase that researchers describe as pre-commercialThe technology is proven and the product is technically ready to be transferred to dairy companies interested in incorporating it into their catalog.
INTA explains that the big challenge now is industrially scale up productionMoving from test batches to commercial volumes involves adjusting parameters, optimizing costs, and adapting equipment to ensure that quality is maintained when working with larger quantities.
This development opens up an opportunity for the dairy industry The idea is to incorporate a high value-added product by utilizing mozzarella already produced for other uses, such as export or the pizza and ready-meal industry. Freeze-drying allows this cheese to be transformed into a shelf-stable snack with a differentiated market position.
The researchers point out that at least one company is already interested in pursuing this avenue, although the project remains open to new partnerships with the private sector. The idea is that technology transfer will allow the product to reach both institutional channels, such as school meals, and the general public. general consumption.
Looking to the medium term, mozzarella chips could inspire the development of other functional dairy snacksLeveraging the experience gained in freeze-drying and the design of practical and stable formats, the combination of science, technology, and a social focus that has guided this project suggests that innovation in this field still has ample room for growth.
However, this development of freeze-dried mozzarella chips It stands out as an eye-catching proposition: it concentrates the nutritional value of milk in small, crispy discs, does not require refrigeration, adapts well to school settings and areas with limited resources, and offers the dairy industry a way to add higher value-added products in an increasingly demanding market.
