Colourful Doughs with Natural Powders: Tests and Results

[vc_row][vc_column][vc_column_text]To obtain colourful doughs in a completely natural way, without artificial colourings, it is possible to use fruit or vegetable powders. The addition of such powders to the flours in the usual process gives the dough particular shades that make it appealing and original. The coloured effect can be modified with the addition, in minimal and controlled percentages, of acidic or basic substances.[/vc_column_text][/vc_column][/vc_row][vc_row content_placement="middle"

we show you the results obtained from the application of acids and bases to the colourful doughs. We conducted the test in our laboratory, using tomato powder as the colouring agent, lactic acid as the acidifier, and sodium bicarbonate as the base. We prepared 7 different doughs, of which 3 with bicarbonate, 3 with the acidic substance, and one left neutral, according to the following table:

1. Flour, Water, Yeast, Salt, (5%) Tomato - neutral dough;
2. Flour, Water, Yeast, Salt, (5%) Tomato, (1%) bicarbonate;
3. Flour, Water, Yeast, Salt, (5%) Tomato, (1%) lactic acid;
4. Flour, Water, Yeast, Salt, (5%) Tomato, (2%) lactic acid;
5. Flour, Water, Yeast, Salt, (5%) Tomato, (2%) bicarbonate;
6. Flour, Water, Yeast, Salt, (5%) Tomato, (0.5%) lactic acid;
7. Flour, Water, Yeast, Salt, (5%) Tomato, (0.5%) bicarbonate.

The intensity of the colour increases with the addition of lactic acid. Conversely, the colouration decreases with the use of bicarbonate. As can be seen from the images, as acidity increases, the colouration becomes more intense, peaking at 2% lactic acid added (sample no. 4). Conversely, increasing sodium bicarbonate, thus alkalising the dough, decreases the colouration and favours the Maillard reaction, creating a more golden crust (sample no. 5).[/vc_column_text][vc_column_text css="%7B%22default%22%3A%7B%22margin-top%22%3A%2220px%22%7D%7D"] [/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][us_image image="13912"][/vc_column][/vc_row]
