In the heart of the provinces of Jujuy and Salta, an ecological and educational initiative is transforming the fate of a common fruit: green bananas. What used to be a discarded product without commercial value is being turned into a versatile, nutritious flour with the potential to diversify the local diet.
The project was born at the National Institute of Agricultural Technology (INTA) Yuto and brings together students from the communities of El Bananal and Río Blanco. With technical support, these young people develop artisanal processes to produce banana flour, an alternative that could position itself as a healthy option and a source of regional income.
The production process is based on simple yet sustainable techniques. The fruit is harvested while still green, cleaned, peeled, and cut into thin slices that are dehydrated in solar dryers. Then, the dried material is ground into a fine powder that preserves the natural nutrients of the fruit, without requiring additives or preservatives.
In addition to the main product, the process generates useful byproducts, such as coarse particles that can replace breadcrumbs in cooking. This comprehensive use of the food reduces waste and promotes a circular economy in rural communities.
An Ecological and Educational Boost
Banana flour represents an opportunity to add value to local production, especially when fresh fruit fails to enter the market due to size or ripeness. Thus, small producers and technical schools find a sustainable alternative to food loss.
The environmental impact is also positive. The use of solar dryers reduces energy dependence and avoids the burning of agricultural residues, while the revaluation of green bananas helps reduce the waste of tons of fruit each year.
The project combines education, science, and environmental commitment. Participating students acquire knowledge about agribusiness, nutrition, and sustainable practices, while strengthening ties with their communities and creating future job opportunities.
In local fairs, the flour has already started to circulate with good acceptance. Breads, cookies, alfajores, and pizzas made with this ingredient show encouraging results and confirm that innovation can arise collaboratively and from the local area.
Conscious and Gluten-Free Eating
One of the main attractions of green banana flour is its potential as a gluten-free food, making it a promising option for people with celiac disease or gluten sensitivity. Although official certification is still pending, the natural process of its production does not include cereals or contaminants containing this protein.
Diseases that prevent gluten consumption —such as celiac disease, non-celiac gluten sensitivity, and wheat allergy— cause adverse reactions when consuming products made with traditional flours. In the case of celiac disease, the immune system reacts by damaging the small intestine, hindering nutrient absorption.
Non-celiac gluten sensitivity generates similar digestive symptoms, although without intestinal damage, while wheat allergy can cause anything from mild discomfort to severe reactions. In all cases, a gluten-free diet is the only way to avoid complications.
Therefore, the emergence of alternative flours like green banana opens the way to a more diverse, inclusive, and local diet. In addition, its neutral flavor and high content of resistant starch provide digestive and energy benefits, expanding the culinary possibilities of healthy cooking.
Rural Innovation with a Sustainable Outlook
Northern Argentina faces a dual challenge: generating economic value without compromising the environment. In this context, banana flour emerges as an ecological, economic, and socially inclusive solution.
In communities where fruit production is abundant but industrialization opportunities are scarce, this INTA initiative offers a replicable model. The coordination between students, teachers, and producers shows that rural innovation can stem from shared knowledge.
The experience of El Bananal and Río Blanco sets a precedent for the comprehensive use of local resources. With institutional support and future certifications, banana flour could establish itself as an emblem of sustainable development in northern Argentina.
