When it comes to plant-based cheeses, consumer enthusiasm often meets a small nutritional limit. Dairy-free alternatives available today are increasingly able to mimic the taste and texture of traditional dairy products, but rarely offer the same protein content.
In recent years, scientific research has begun to focus on this aspect: finding plant-based ingredients capable of offering more complete structure, flavor and nutritional values. And this is where a surprisingly familiar food comes into the picture. A group of US scientists has discovered that rice could become the basis of a new protein-rich vegetable cheese, opening up very interesting scenarios for sustainable nutrition.
A scientific discovery that enhances the proteins present in the grain
Behind this innovation is the work of researchers at the Arkansas Agricultural Experiment Station, the research center connected to the University of Arkansas. By studying the composition of rice, scientists have discovered that each grain contains different types of proteins that can be exploited to create new food products.
Researcher Mahfuzur Rahman explains that protein comes mainly from three parts of the grain: brown rice, white rice and bran. Each of these components has different characteristics and can influence the consistency, elasticity and stability of food products.
The discovery becomes even more interesting if we consider the agricultural context in which it was born. Arkansas is the largest rice producer in the United States and cultivated more than 1.4 million acres as of 2024, contributing nearly half of the nation’s production.
During the industrial processing of rice, enormous quantities of by-products are generated, such as broken grains and rice bran, often destined for feed production or used in brewing. According to the US Department of Agriculture, 14.3 million tons of bran and approximately 24.8 million tons of broken grains are produced each year, an amount that contains millions of tons of protein potentially usable in the food sector.
In other words, what is today considered a simple by-product could become a new nutritional resource for the future of plant foods.
How rice cheese is born
To truly understand the potential of rice, the team led by Rahman and researcher Ruslan Mehadi Galib isolated and analyzed the different proteins present in the cereal. Chemical analysis identified four main molecular components: albumin, globulin, glutelin and prolamin.
These proteins were then used to create experimental versions of rice-based vegetable cheese, combining them with ingredients already common in vegan alternatives, such as coconut oil and corn starch.
The result was surprising: the first prototypes developed by the researchers contained around 12% protein, a much higher value than most vegan cheeses available in supermarkets today.
The research also suggests other possible applications. Rice proteins could in fact be used as a substitute for eggs or oils in various foods, expanding the range of plant ingredients with high nutritional value.
Scientists are already working to make the production process even more sustainable. In initial tests, protein extraction was carried out with hexane, a solvent commonly used in the food industry for the extraction of vegetable oils. However, the team is experimenting with alternative methods based on ultrasonic waves, which could reduce the environmental impact of production.
Rice cheese, therefore, represents much more than a simple gastronomic curiosity. It could become an important piece in the construction of a more sustainable food system, capable of valorising the agricultural resources already available and transforming processing waste into ingredients with high nutritional value.
The journey is still at the beginning, but the direction appears clear. In a world that is increasingly looking for sustainable, nutritious and accessible food solutions, even a simple grain of rice can prove surprisingly revolutionary.
