Why does bread go stale?

Fresh bread is one of life's simple pleasures: a crisp crust on the outside and a soft, springy inside, which bakers call the crumb. Yet after only a day or two on the kitchen counter, the same loaf can become firm, crumbly and far less pleasant to eat. Most people would say that the bread has simply dried out. Surprisingly, that explanation is only partly correct.

The main reason bread goes stale is a change in starch, the substance that makes up most of the flour. When dough is baked, heat and water cause tiny grains of starch to swell and lose their neat internal pattern, and this gives fresh bread its soft texture. As the loaf cools, however, the starch slowly begins to line up again into a more ordered structure. As this happens, the starch holds water less tightly, and the crumb feels hard and dry, even though much of the water is still inside the loaf.

This explains why bread that is tightly wrapped in plastic still goes stale. Wrapping stops the loaf from losing water to the air, but it cannot stop the starch from slowly changing.

The crust changes too, but in the opposite direction. Over time, moisture moves outwards from the crumb into the crust, so the crust loses its crunch and becomes soft and leathery.

Temperature also matters. Perhaps surprisingly, the starch changes happen fastest at the cool temperatures found inside a fridge. A fridge helps to stop mould, but a loaf kept there usually goes stale sooner than one kept in a bread bin at room temperature. Freezing, on the other hand, almost stops the process, which is why sliced bread can be kept in the freezer for weeks and toasted straight from frozen.

Stale bread can also be partly rescued. Heating it in a hot oven for a few minutes loosens the starch again, and the crumb becomes soft for a while. The effect does not last, though, so the bread should be eaten immediately. Loaves made with some fat or sugar generally stay soft for longer than simple ones made only from flour, water, yeast and salt. And bread that is past its best need not be wasted: it makes excellent toast, and it can be turned into breadcrumbs for cooking.

Soluzioni

Completamento di frasi

  1. crumb / the crumbIl brano dice che l'interno morbido ed elastico è ciò che i panettieri chiamano mollica (crumb).
  2. dried outIl brano dice che la maggior parte delle persone direbbe che il pane si è semplicemente seccato, ma questo è corretto solo in parte.
  3. starchL'amido è la sostanza che costituisce la maggior parte della farina, e un cambiamento dell'amido è il motivo principale per cui il pane raffermisce.
  4. orderedIl brano dice che l'amido comincia a riallinearsi in una struttura più ordinata.
  5. leatheryLa crosta perde la sua croccantezza e diventa molle e coriacea.
  6. fridgeI cambiamenti dell'amido sono più rapidi alle temperature del frigorifero, quindi il pane conservato in frigo raffermisce prima.
  7. freezerIl congelamento blocca quasi del tutto il raffermimento, quindi il pane a fette può essere conservato nel congelatore per settimane.
  8. breadcrumbs / bread crumbsL'ultima frase dice che il pane vecchio può essere trasformato in pangrattato da usare in cucina.

Scelta multipla

  1. c) to explain why bread goes stale and how storage affects itIl brano spiega le cause del raffermimento e come l'incarto, la temperatura e il riscaldamento lo influenzano.
  2. b) The starch keeps changing even when no water escapes.L'incarto impedisce all'acqua di fuoriuscire, ma non può impedire che l'amido cambi lentamente.
  3. d) Much of it stays in the loaf but is held less tightly.La mollica sembra asciutta perché l'amido trattiene l'acqua con meno forza, anche se gran parte dell'acqua è ancora all'interno.
  4. a) The crust gets softer while the crumb gets firmer.La mollica diventa compatta e friabile, mentre la crosta perde la croccantezza: il brano dice che cambiano in direzioni opposte.
  5. c) It makes the crumb soft, but only for a short time.Il calore allenta l'amido e ammorbidisce la mollica, ma l'effetto non dura, quindi il pane va mangiato subito.
  6. b) bread made with some fat or sugarIl brano dice che le pagnotte fatte con un po' di grasso o zucchero in genere restano morbide più a lungo di quelle semplici.
