Full of life

Like many of the fermented products having ancient origins (beer, wine, and cheese), these are the micro-organisms that give the good flavors. After having fed the sourdough with water and flour for a few days, the mixture becomes a community prolific : a population of lactic acid bacteria living in harmony with wild yeasts from the flour and from the air. In each teaspoon of yeast, there are five billion bacteria lactobacilli and $ 50 million of yeasts. The sourdough ferment naturally… releasing carbon dioxide, this fermentation allows the dough to rise.

The taste of this bread is slightly tart, with complex aromas and subtle because of the acids that are released from the lactic acid bacteria of the leaven.

Health benefits

Its nutritional composition depends, above all, the type of flour used to prepare it. White flour, ultra-refined has a nutritional value less than a rye flour or spelt. The fermentation process improves the nutritional profile of this type of bread in several ways. The lactic acid bacteria to increase its acidity. This contributes to the degradation of phytate by about 50 % compared to the yeast conventional, which allows a better absorption of the minerals present in the sourdough bread for the body and digestion more easy.

This feature also increases the feeling of satiety. Finally, the fermentation own sourdough could change the structure of the molecules of the carbohydrates in the bread. This would slow down the speed at which their sugars enter the blood, reducing the glycemic index.
