Oxidisation

Paul Walton, Head of Chemistry at York University, demonstrates how to avoid the oxidation of food in this short video clip produced by Bettys & Taylors. He explains the process of enzymatic browning in apples, the loss of antioxidants during boiling and how to prepare food to maintain its appearance and...

Changing Molecules

In this video clip produced by Bettys & Taylors, Paul Walton, Head of Chemistry at York University, demonstrates the changing behaviour of protein molecules in egg. He models the effect of agitation on the tertiary structure of globular protein molecules using a piece of string to represent the amino acid...

Bicarbonates

In this video clip produced by Bettys & Taylors, Paul Walton, Head of Chemistry at York University, demonstrates the reaction of sodium bicarbonate with hydrochloric acid, explaining how carbon dioxide can be released from carbonates either by heating or by reaction with an acid, which makes them a useful...

Emulsions

Paul Walton, Head of Chemistry at York University, demonstrates emulsification in this short video clip produced by Bettys & Taylors. He shows how an agent such as an egg, mustard or honey can be used as an emulsifier to bind hydrophilic and hydrophobic molecules together. He demonstrates this by mixing oil...

Exploding Jellybabies

Paul Walton, Head of Chemistry at York University, demonstrates the calorific content of food in this video produced by Bettys & Taylors. He drops a jelly baby into a boiling tube containing potassium chlorate, which oxidises the sugar to release energy in a dramatic exothermic reaction. This can be compared...

Denaturation

Paul Walton, Head of Chemistry at York University, demonstrates denaturation in this video produced by Bettys & Taylors. He models the structure of a protein using a piece of string to illustrate how it can change under certain conditions, affecting the properties of protein in food. Paul demonstrates this...

Boiling Vegetables

In this video produced by Bettys & Taylors, Paul Walton, Head of Chemistry at York University, demonstrates the effect of boiling on the nutritional content of vegetables. He describes the relative sizes of the molecules of insoluble carbohydrates compared to those of soluble vitamins and minerals, and a...
