This resource introduces students to the seven main classes of food additives used in the U.K. food and drinks industry. These comprise of preservatives, sweeteners, anti-caking agents, antioxidants, colours, flavourings and emulsifiers. A short video acts as a starting point to the activities that follow. A...

Gelling agents

This resource investigates the use of pectin as a natural gelling agent in the manufacture of jams and preserves to retain their viscosity. A worksheet based task acts as an introduction, leading to investigations to identify the conditions necessary for gel formation using liquid pectin.

Flavour

This resource investigates the use of flavourings in a milkshake. Natural and artificial vanilla flavourings are used to manufacture the product and a taste panel used to judge the preferred flavour. Costs of manufacture are also calculated in the activity.

Emulsifiers

This resource can be used to demonstrate an understanding of the role of emulsifiers and stabilisers in the food industry to retain the physical quality of products in terms of texture and mouth feel. A research task involves a survey of commercially produced coleslaw and designing and manufacturing an equivalent....

Food colouring

This resource can be used to demonstrate an understanding of the role of food colourings in products. Activities include an extraction of the food colours used in sweets and then a separation of these colours using chromatography. A final task involves investigating how acid and alkali levels affect both natural...

Antioxidants

This resource can be used to demonstrate an understanding of the role of antioxidants in food processing to delay oxidation. A data based activity analyses types of fat in foods and an investigation into the browning of apples under varying conditions allows a quantitative measure of the oxidation reaction. 

Anticaking agents

This resource can be used to demonstrate an understanding of the use of anti-caking agents that allow powdered food products to flow more freely through machinery. The action of an anti-caking agent in cocoa powder is investigated in one activity and a case study using real results from an industrial setting...

Acidulants

This resource can be used to demonstrate an understanding of the use of acids and alkalis in the food and drinks industry. A series of activities involving the preparation of sherbet, scones and dumplings using raising agents illustrate the function of acidulants. The flavouring and preservative nature of citric...
