Science of Bread: Bread Science 101
From Chinese baozi to Armenian lavash, bread comes in thousands of forms. What do they have in common? On the most basic level, they all involve cooking a mixture of milled grains and water. Imagine a continuum of breads, ranging from the thinnest flatbreads to the fluffiest brioche. Some are amazingly simple: Matzoh, for example, is nothing more than flour and water, baked until crisp. Raised breads, on the other hand, involve the complex interactions between flour and the leaveners that give them their porous, tender quality. Leaveners come in two main forms: baking powder or soda and yeast. Baking powder or baking soda work quickly, relying on chemical reactions between acidic and alkaline compounds to produce the carbon dioxide necessary to inflate dough or batter (more on this later). Yeast, on the other hand, is a live, single-celled fungus. But leavening agents would just be bubbling brews without something to contain them. For more about bread science, check out these links!

Raising Agents: The Agents which give Lift to your Baking! RAISING AGENTS fall into three specific categories: Chemical, Mechanical and Natural The main two Chemical Leaveners used in Baking are: Baking Powder and Baking Soda. BAKING SODA BAKING POWDER Baking Soda vs. Baking Powder Summary Baking soda and/or baking powder are added to batters for leavening; i.e., in order to produce the gas that make cakes, muffins, and quick breads rise.Baking soda + liquid acid (in the recipe) ---> leaveningSingle-acting baking powder = baking soda + a dry acid. When the liquid ingredients are mixed with the dry ingredients you get leavening --OR-- when the product is heated you get leavening.Double-Acting baking powder = baking soda + 2 dry acids.

The Chemistry of Ginger – Flavour, Pungency & Medicinal Potential Ginger is a spice that can be commonly found in supermarkets and in the kitchen, either as the fresh root, or in dried, powdered form. It adds a strong, pungent flavour to dishes as a consequence of a number of chemical compounds it contains; additionally, these compounds are altered when the ginger is cooked or dried, producing alterations to its flavour. Some of these compounds have also been investigated for potential health benefits, including potential anti-tumour activity.

8 Tips For Better Bread Making How to Bake Great Bread at Home Many people are extremely intimidated by bread making.

Who says your diet is chemical free? · Blog Posted by Lauren Tedaldi on 19 May 2014 Today we’re launching a new edition of ‘Making Sense of Chemical Stories', to stop people being misled by chemical myths. With chemicals ever-present in the media, the guide has been revised to help people make sense of chemical stories. The guide was published in partnership with the Royal Society of Chemistry.

Paul Hollywood Here are some of my top tips to ensure your bakes are perfect every time. Lighter crustsFor a better crust, set your oven to around 220°C/425°F/Gas7 and leave a roasting tray in the bottom of the oven to heat up. When the oven reaches the right temperature and just as you put the bread in to bake, fill the tray with cold water. This creates a steam bath in the oven which helps the bread to have a lighter crust and prevents tearing. Lethal Doses of Water, Caffeine and Alcohol Click to Enlarge Today’s graphic is a whimsical look at lethal doses of chemicals we consume on a regular basis. Whilst it may be more common to view chemicals in a black and white framing of ‘toxic’ or ‘non-toxic’, the reality is more of a sliding scale of toxicity.
