This unit introduces learners to a range of storage facilities and technological kitchen equipment with a focus on practical applications. Outcomes Investigate the storage facilities required to maintain the quality of a range of foods. Explain the use of a range of technological kitchen equipment required to carry out a range of food preparation and cooking activities. Use technological kitchen equipment to carry out food preparation and cooking activities in a safe and hygienic way. For full details please refer to the SQA National Course Specification. TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 5 TEACHER’S NOTES The assessment sheet in the Student Workbook outlines the learning intentions within each outcome. Learners can be encouraged to engage in self-evaluation using this sheet to record how well they feel they have performed. Although a traffic light method of evaluation is suggested, this can be adapted to suit the learner. The evaluation sheets used after trialling and investigating each piece of technological equipment can also be used as an assessment tool. This will give an indication as to how well the learner has covered and understood the learning outcomes. It is envisaged that the activities contained within the Student Workbook will be undertaken following practical work involving real food products. Whether this will be in the usual learning environment such as a classroom or elsewhere in a professional kitchen or supermarket will vary depending on the resources available to different establishments. This support resource is designed to supplement and consolidate hands on experiences in the home economics classroom. It does not attempt to include the full range of technological kitchen equipment. This is because it is envisaged that many pieces of equipment will be introduced to learners in practical tasks. Equally, each learning environment will have a different combination of technologi cal kitchen equipment available. The equipment the client group are familiar with outside the school setting will also influence the choice of technological equipment used. Examples of popular pieces of technological equipment have been chosen. This introduces students to the real world as well as supplying up-to-date resources and information. Recipes have been included, but there is flexibility for each establishment to use their own recipes suitable for each piece of technological equipment. It is hoped that this unit of work will provide a basis of information that will encourage students to further investigate aspects of technology whilst endeavouring to widen their learning experience. 6 TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 COURSE ASSESSMENT Course assessment Outcome 1 – In this unit I will learn to Identify a range of food storage facilities Identify the appropriate storage facility for a range of foods Identify the safe storage time for a range of foods Keep the food storage facilities and their contents safe and hygienic Outcome 2 – In this unit I will learn to Identify a range of technological kitchen equipment Explain the main use of each piece of equipment Outcome 3 – In this unit I will learn to Select the best equipment for an activity Correctly use the technological equipment Correctly maintain and store the equipment Be safe and hygienic at all times When you have covered each learning intention, show how well you think you have learned using red, amber and green colours in the box beside it.

To find the answer to this we must go back to our ancestors. They tried different ways of storing food but discovered that, as hard as they tried, food deteriorated. Eventually, it was discovered that there was one offender responsible for this; microbes. Microbes need a number of things to continue to grow: warmth, moisture, time, the correct pH and food. To preserve our food we need to stop the growth of microbes by removing one or more of these conditions. We do this by the following means: 1. warmth – by cooling or freezing food 2. moisture – by drying food or by storing food in dry conditions 3. time – by using sell-by and use-by dates 4. correct pH – by ensuring the correct acid/alkaline levels 5. food – by ensuring hygienic conditions and that food is properly covered. TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 9 INTRODUCTION TO FOOD TECHNOLOGY Use the internet or a dictionary to give a definition for the following terms: best-before date ________________________________________ cross-contamination ________________________________________ food hygiene ________________________________________ perishable food ________________________________________ food poisoning ________________________________________ pH level ________________________________________ danger zone ________________________________________ use-by date ________________________________________ 10 TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 INTRODUCTION TO FOOD STORAGE Introduction to food storage The three Cs Why is correct food storage so important? If we do not store food properly it will deteriorate very quickly. This can cause food poisoning and it is also a waste of resources. Remember the three Cs Keep it c _ _ _ Keep it c _ _ _ _ Keep it c _ _ _ _ _ _ Now draw a picture in each box which will remind you of the three Cs. TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 11 KEEP IT COOL Keep it cool Food deteriorates in certain conditions. Microbes need w___________ to grow, therefore if food is kept cold the growth of microbes will be slowed down. This is the basic principal of chilling and freezing food. How did the Eskimos preserve food? They knew that if they put their catch of fish out into the intense cold it would freeze very quickly. Then, when they went to use the fish, it still had a fresh flavour. This meant that they could have a fresh supply of food whenever they wanted. This is the same principle that we use on a worldwide scale today. Now give examples in the table below of foods that can be listed under each of the headings. Frozen fruit 12 Frozen vegetables Meats Fish TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 Poultry Ready meals KEEP IT COOL The germ thermometer The diagram below shows what happens to germs at different temperatures. At 100°C all bacteria are dead 100°C Above 63°C the spread of bacteria begins to slow down as conditions get hotter Between 4°C and 63°C bacteria begin to slow down as conditions get hotter. 63°C Bacteria are at their most comfortable at the ideal temperature of 37°C. This is the same temperature as our own bodies. Our stomachs make an excellent home for bacteria. The stomach is like an incubator which keeps a newborn baby’s temperature at the correct level. 37°C 4°C A refrigerator works at 4°C keeping food chilled but not frozen. Bacteria do not react to the chilly temperatures and remain inactive. 0°C Below 0°C bacteria become dormant. –18°C At an even lower temperature of –18°C the deep freeze preserves food safely as the bacteria are inactive due to the extreme cold. TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 13 KEEP IT COOL From the information given on the previous page, write down what will be happening to bacteria at the following temperatures. Temperature What is happening to the bacteria? –21°C 5°C 40°C 80°C 100°C 14 TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 KEEP IT COOL Now draw your own germ thermometer in the space below. Remember to colour code the thermometer to illustrate the various temperatures , showing what happens to food at each of these temperatures.

What do we mean by food technology? Food technology is all about changing food from its raw state to suit our needs as individuals and families. If we want to have a variety of foods available to us throughout the year we need to preserve foods to make the most of them when they are in season. As we have noted already food deteriorates very quickly unless it is preserved and stored in the correct way. We have already seen that bacteria need certain conditions to grow and multiply. Can you list below what these conditions are? 1. 2. 3. 4. 5. Food preservation techniques have changed a lot over the years and methods of food preservation have become more sophisticated. Through history people have tried out many methods of food preservation in order to survive. Can you list what some of these methods of food preservation were? 1. 2. 3. 4. 5. 6. TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 29 FOOD PRESERVATION Give three examples of very early methods of food preservation. For each of these, give an explanation as to why the food did not deteriorate and people were able to utilise food that was plentiful at certain times of the year. 1. 2. 3. Your teacher has a display of foods that have been preserved. We refer to these foods as convenience foods because they have been produced and packaged so as to extend their shelf life, and because they are quick and easy to use. Identify each method of preservation and give an example of each in the table below. Methods of preservation 1. 2. 3. Compare your list with those of the rest of the class. 30 TECHNOLOGY IN THE KITCHEN (ACCESS 3, HOME ECONOMICS) © Learning and Teaching Scotland 2010 4.
