Understanding the Concept of Processed Food
The term “processed food” can be broad, ranging from minimally altered foods to heavily manufactured products containing many additives. The USDA, for instance, often categorizes foods based on the degree of processing. Minimally processed foods might include washed and packaged vegetables, while heavily processed foods are items like ready-to-eat meals and sugary drinks. Where does a traditional food like amala, with its distinct preparation, fit into this spectrum? To answer this, we must look at the steps involved in making the flour, known as elubo.
The Traditional Method of Making Amala Flour
The process of making amala flour, especially from yam (elubo isu), is a meticulous, multi-step tradition passed down through generations.
- Peeling and Slicing: The yam tubers are first peeled and cut into thin slices. This is the first mechanical step of breaking down the raw product.
- Blanching or Fermenting: The slices may be briefly blanched in boiling water or fermented. This changes the texture and chemical composition. Fermentation, in particular, adds a distinct flavor and can improve the nutritional profile.
- Drying: The yam slices are then dried, traditionally in the sun, which is a method of preservation. This dehydration process fundamentally changes the yam's form.
- Milling: Once completely dry, the hard, brown slices are ground into a fine powder, the flour known as elubo.
- Sieving: The flour is sieved to achieve a uniform texture, which is crucial for a smooth, lump-free amala.
These steps, while traditional and without chemical additives, do represent significant processing. The raw yam is transformed from a fresh tuber into a shelf-stable flour.
Industrialization and its Impact
With increased demand and urbanization, the production of elubo has moved from primarily a household chore to an industrial process. Factories use large-scale machinery for peeling, slicing, and milling. Industrial dryers may replace sun-drying, speeding up production. While the core steps remain, automation increases the scale and consistency of the processing. However, unlike highly processed products, the final amala flour remains a single-ingredient product: ground yam, cassava, or plantain, with no added preservatives or flavor enhancers.
Amala: A Comparative Analysis
To better understand amala's place on the processing spectrum, let's compare it with other common food items.
| Feature | Amala | White Bread | Frozen Vegetables |
|---|---|---|---|
| Processing Steps | Peeling, slicing, drying, milling, sieving. | Milling, bleaching, mixing, proofing, baking, slicing. | Washing, chopping, blanching, freezing, packaging. |
| Key Ingredients | One base ingredient (yam, cassava, or plantain) and water. | Refined wheat flour, water, yeast, salt, sugar, additives. | One or more vegetables. |
| Preservatives | None added during traditional or standard industrial processing. | Often contains preservatives to extend shelf life. | None, or only natural preservatives, if any. |
| Nutritional Change | Nutritional content altered by drying, but largely intact. | Fiber and nutrients significantly reduced during milling. | Nutrients are well-preserved through blanching and freezing. |
| Classification | Minimally to moderately processed. | Highly processed. | Minimally processed. |
Is Amala Less Healthy Because it's Processed?
Processing is not inherently a negative factor. For amala, the processing of drying and milling is primarily for preservation and convenience. It allows a perishable food source like yam to be stored and transported, providing year-round access to a staple food. The nutritional value is still largely present, with amala being a good source of carbohydrates, dietary fiber, and various vitamins and minerals. For example, amala made from unripe plantain flour (elubo ogede) is known for having a lower glycemic index, making it suitable for diabetics. The healthiness of an amala meal often depends more on the accompanying soup and overall portion size.
Conclusion
While amala is certainly a processed food, it is a minimally to moderately processed item, far removed from ultra-processed, additive-filled products. The preparation involves transforming a raw ingredient (yam, cassava, or plantain) into a flour to extend its shelf life, a practice that is centuries old. Ultimately, amala's status as a 'processed food' should be viewed through the lens of its traditional preparation and nutritional profile rather than the negative connotations often associated with the term. The rich cultural tradition of creating this popular Nigerian swallow ensures that it remains a nourishing, wholesome part of a balanced diet when paired with healthy soups.
Note: The nutritional value and processing level can differ slightly based on the type of flour (yam, cassava, or plantain) used for amala. For instance, cassava-based amala (lafun) is typically lighter in color and texture.

How the different types of amala are made
There are three primary types of amala, each originating from a different processed tuber or fruit.
- Yam Flour Amala (àmàlà isu): The most common type. Peeled and sliced yams are dried, which causes them to turn a brown color, before being ground into a dark brown flour. The result is a distinctive dark amala.
- Cassava Flour Amala (àmàlà láfún): Made from dried cassava flour, known as lafun. Cassava does not change color during the drying process, so the resulting amala is white.
- Unripe Plantain Flour Amala (àmàlà ogede): Prepared from unripe plantain flour, this type is lighter in color and texture. It is often recommended for individuals managing diabetes due to its lower carbohydrate content.
The process of preparing amala from flour
Preparing amala from the dry flour is a straightforward but skilled process. A cook mixes the flour into a pot of boiling water and stirs vigorously with a wooden spatula until it forms a thick, smooth dough with no lumps. The resulting swallow is then served hot with a variety of Nigerian soups like ewedu or gbegiri.
Amala and dietary considerations
- Amala as a Gluten-Free Option: Amala made from yam, cassava, or plantain flour is naturally gluten-free, making it an excellent choice for individuals with celiac disease or gluten sensitivities.
- Portion Control: As with any staple food high in carbohydrates, portion control is important. Eating amala in moderation, as part of a balanced diet with nutrient-rich soups, is key to reaping its benefits.
