Why does panettone last so long?
Why does panettone keep for so long?
You probably know it if you consume it, even occasionally, panettone is a specialty that has the ability to keep for a relatively long time. Generally, specialties such as brioches can keep for a few days, but not several weeks. But panettone stands out for a much longer shelf life than the average, without losing its taste qualities and its aromatic richness. So, why does panettone keep for so long? Christophe Louie, an artisan specializing in panettone making, tells you more.
The first secret to panettone preservation: sourdough
If you're wondering why panettone keeps for so long, the primary reason for this longevity lies directly in the panettone making recipe. This Italian specialty is traditionally made with sourdough. Nowadays, some professionals, like Christophe Louie, perpetuate this know-how and continue to produce artisanal sourdough panettone.
And it is partly thanks to this sourdough that panettone can keep for so long. The use of sourdough, with a long dough fermentation, allows for higher acidity development, which has the effect of lowering the dough's pH and, thus, delaying the staling of the panettone.
Why panettone keeps for so long: an environment not conducive to mold growth
You now know the first reason why panettone keeps for so long, but a second factor should also be taken into account: the overall environment offered by panettone.
Indeed, while sourdough partly explains panettone's shelf life, it is not the only factor contributing to its longevity. It should also be noted that the significant use of butter and sugar has a real impact on panettone's shelf life. The use of these products, coupled with the use of sourdough, results in a dough that remains moist, but is low in water.
However, when a product's water activity is high, mold growth is facilitated. Therefore, thanks to these properties, panettone does not present an environment conducive to mold growth and can thus be stored for longer.
