toc media type="custom" key="5648701" = Introduction = Food manufacture and processing, can make food more edible and enables us to keep and store food products for longer. Much of the food we eat and drink has been processed in one way or another. During this course you have made a number of dishes which have used both raw foods - e.g. vegetables and fruit, and you have used processed foods - e.g. flour and sugar. Foods can be classified into two main groups: The changes made to raw foods to make them more palatable or edible are known as **food processing**. Food processing involves changes to the raw materials which can improve: Food processing is classified into two main areas: = Task 1 = Read the text on pages 12, 34, and 68 of Food Technology by Campbell, Clapton, & Tipton Make a table for each of the following: = Task 2 = Copy and complete the following table: Converted into || **Secondary Source** Food ingredient || **Secondary Processing** Manufactures into || **Food Products** || //Image// || =** Task 3 **= Discuss why combining primary foods creates additional properties such as: Read the case study about cheese on page 68
 * **Primary source** - raw food materials - e.g. milk, fruit, vegetables, wheat grain, sugar beet.
 * **Secondary source** - processed food materials - e.g. butter, jam, flour, sugar.

 * //ease of preparation//
 * //storage properties//
 * **Primary processing** - the changing or converting of raw food materials into - e.g. food that can be eaten immediately, or be processed further into other food products.
 * **Secondary processing** - the changing or converting primary processed foods into other food products, it may involve combining one or more food ingredients - e.g. making a cake with eggs, milk, butter, sugar & flour
 * Find 6 examples of each - primary and secondary sources of food material.
 * Find 6 examples of each - primary and secondary food processing.

 * Increased nutrition e.g. adding egg to dough mixture increases protein.
 * Improved organoleptic qualities e.g.
 * 1) Changing appearance to enhance aesthetics (milk glaze on pastry, grilled cheese topping on a pie)
 * 2) Changing texture (seeds on top of bread, nuts on a dessert)
 * 3) Changing flavor (adding cheese or herbs to pastry, lemon zest to cakes, cream to sauces, spices to biscuits/sauces)

= Task 4 = Sugar is used in many food products, for example cakes, biscuits, meringues, etc. However sugar is also added to products you may not immediately think of. Look at the following lists of ingredients. = Key Words = These are the key words for this week, check that you know what they mean.
 * 1) Which food products do you think are made from each list of ingredients?
 * 2) What is the function of sugar in each of these products?
