Drying (reduction of dough/batter moisture) Inactivation of naturally-occurring and added enzymes inside the dough (70–85☌) (160–185☏).Ģ.This is the start of the dough-crumb transition process (setting). Above 85☌ (185☏), starch looks glassy, and gluten looks rubbery.As a consequence, gluten becomes increasingly tough and stiff as it irreversibly forms a gel.

It starts at 55–65☌ (130–150☏) as granules become fully swollen with local free water. The enzyme-driven reactions that convert starch into sugars and break proteins into amino acids increase with heat, so they increase most near the dough surface.
Maximum enzymatic activity at 60☌ (140☏).Oven spring is accompanied by the following changes and conditions:
BAKING TIME TEMPERATURE CONVERSION CHART SERIES
In this stage, the product undergoes a series of irreversible chemical and physical transformations. Note that the size to which the gas bubbles can grow is limited by the ability of the gluten/starch film surrounding them to stretch without rupturing. This results in a large reduction in the density of the dough as the product gradually develops an aerated structure. Development (also known as oven spring)Īs temperature increases, the free water/alcohol mixture in the product vaporizes, fermentation gases (CO2) dissolved in the liquid dough phase become less soluble, and are released into the cells, causing them to expand in response to the rise in pressure.Īs a result, cells increase in volume by retaining gases due to their deformable nature as these are surrounded by the continuous gluten/starch soft matrix. The following stages are temperature-dependent, and participate in the sequential transformation of bread dough. It’s considered ‘old money’, in the same way that schools teach the metric system of measurements.Oven temperature causes physical transitions and chemical reactions to take place in the dough/batter. These days, nobody really uses Fahrenheit. This was before we could use an internet search engine to find an oven temperature conversion guide! “Eureka! Got it! Gas mark 4 is 350 degrees Fahrenheit! Get the oven on!” We would come home and frantically search cook books until we found a recipe that used the same temperature. When she passed on a recipe, she would casually say, “Gas mark 4, for 20 minutes.” as though we knew what that would be in Fahrenheit. My mum’s mum, on the other hand, had a gas oven and hob. I didn’t relate Fahrenheit to anything else, at school I was taught about temperatures using centigrade, or Celcius, but I still used Fahrenheit at home. I learnt to cook on it, using Fahrenheit as the temperature scale. When I was growing up, my mum had an electric oven and hob.
Check below for our oven conversion chart! Here at Pinch of Nom we use electric fan oven temperatures in our recipes. It’s really useful when I pick a recipe that doesn’t give me a fan oven temperature. In my kitchen, I have a oven temperature conversion guide.
