Think about how can I change the design to be suitable for people with special diets? Vegan People who eat no animal products including meat, dairy (from animals milk) eggs and fish. Many vegans avoid wearing animal products also. Vegetarian / vegetarianism. People who chose for a moral, religious or health reason to exclude meat from their diets. (this can include fish, shellfish, animal meats and poultry) . Gluten Is found in grass related grains, wheat, maize, rice ,rye and barley. People who have an allergy towards gluten should avoid these foods and or eat alternatives. Lactose Intolerance Is an allergy towards milk it can cause suffers to suffer from allergic reactions and in some cases this can cause convulsions. Coeliac disease Is an intolerance to the protein gluten, which is found in wheat, barley and rye. Food such as bread, biscuits, cakes and pasta must be avoided. Peanut allergy This often effects small children and as a health warning children under 3 years due to the effects the allergy can cause.
You need to know about the nutritional information related to bread and the dips you design. Always use the eat well plate if you struggle to remember certain information. Keywords Nutrient – the part of the food that performs a particular function in the body.
What needs to be on the packaging? • The product Name • List of ingredients • Weight or volume • Storage instructions • Use by date/best before date • Manufacturer • Place of Origin • Allergic information
We know that the second section can be on the anything. • I have broken the next section down into sections to help you revise. • Research Methods • Data Analysis • Sensory Analysis • Healthy Eating • Temperatures • Developments • Nutritional information • Production (specifications) • Control Checks • Problems in production • Standard components • Environmental Issues • CAM/CAD • Additives
Research Methods List the different ways to find out information Product Analysis Prior Knowledge Books Nutritional information Internet Questionnaire Internet
Make sure you triple check your answers when using data they have given you. Silly mistakes can be made loosing easy marks.
Sensory Analysis – What is it? What do I need to know? The senses are key to a good analysis of a food product. Sensory testing is carried out to analyse food products. You would have done sensory testing in your controlled assessment to help you evaluate your work. You must be able to explain how these tests can be carried out.
Ranking Tests • These type of tests are used to test similar products in terms of specific flavour, e.g. sweetness • Each sample should be coded and not put in a rank order. There should be a minimum of ten untrained tasters. • Testers would need to put the products in order of sweetness • Results could be recorded on a table • Profiling test • This is a star diagram – remember your coursework! It is normal to use a 6 point star diagram. This can be based on descriptive words, e.g. bland, fruity, crunchy. • Rating testing • These tests are used to assess a specific flavour or texture. Must be tested by a trained tester. This could involve a seven point scale • Dislike extremely • Dislike a lot • Dislike a little • Average • Like a little • Like a lot • Like extremely
You must have a good knowledge of the eat well plate. It is very useful to help with nutrients
Carbohydrate for energy • Fat for energy, warmth, protection • Vitamin A for healthy eyesight, mucus membranes, healthy skin • issue, night vision • Vitamin B for release energy, formation of red blood cells • Vitamin C for general good health, iron absorption, healthy skin, • gums, builds immune system and fights infection • Vitamin D for calcium absorption and growth and maintenance of • strong bones • Iron for healthy blood and transfer of oxygen around body • Calcium for healthy bones and teeth, healthy muscles and nerves Brushing your teeth is boring! Create nutrient cards and put them around your bathroom mirror to help you revise while brushing your teeth to keep your amused! Nutrient: Source: Function:

High Risk foods can lead to food poisoning . The following are symptoms of food poisoning. Headache Dizziness Vomiting Stomach cramps Diarrhoea
What is a high risk food? A food which is an ideal medium for the growth of bacteria or microorganisms. We like moisture, protein and warmth to grow
What is a control Check? You will be asked to relate to control checks in both sections of the exam. A control check is a step taken to ensure a product is consistent and of the same quality. Safety checks are also to ensure consistency
You need to know what a specification is asking for. There are two types of specification. • Design specification • This will be a general list of bullet points about what your design must have. A lot of the information will come from your research. Specify points such as: • Target group • Diets • Ingredients • Nutritional information e.g. low in salt • Texture • Cost • Product Specification • This is a very detailed specification and uses information gathered from research and design ideas you have tested out. You will eventually evaluate your work against the product specification. A product specification will be relevant to just one product. E.g. Meatballs and pasta.
The exam may give you situations for you to develop your dish. Have a go at the few below?
You need to know how to highlight a fault when a product has not turned out well and suggest how it can be prevented. Have a go at the following.
What is a standard component? A Standard Component is a pre-prepared item/ingredient that is used in the production of another product. You must be able to • Understand and define the term ‘Standard Component’ • Understand why standard components are used in food production • To identify the advantaged and disadvantages of using a standard component.
What do I need to know about the environmental considerations? • Understand how the use of packaging has an impact on the worlds resources • Understand the sourcing of food affects the environmental climate. Answer the questions on the next page to help you revise. You will need to know the answers
What are farm assured foods? What are Food miles? What are nanofoods?
What are fair trade foods? What are organic foods?
CAD = Computer aided Design Using computer design programs to help with designing a food product for example sensory star diagrams • Understand the difference between CAD and CAM • Understand how each can be used in production CAM = Computer aided Manufacture Using computers to control the process of mass production for example a bread maker
Additives Food additives can be classified as natural or artificial. Natural additives occur naturally in foods. They are extracted and put into other foods. Caramelised sugar is used as colouring in cola. Artificial additives do not occur naturally. They are made synthetically for a certain purposes. For example tartrazine is a synthetic colouring added to some sweets to make them yellow. Uses for additives Both natural and artificial additives are used for many different reasons: Preservatives extend the shelf life of a product. Salt is used used in bacon and sausages. Colouring makes food products look more appealing and appetising. Flavourings can be used to add or improve the flavour of a food product. Vanilla flavouring is often added to cakes and biscuits. Emulsifiers are used to prevent ingredients from separating. For example, lecithin, which is found in eggs, is used to stop the ingredients in mayonnaise from separating. What are Additives?
Good Luck! Don’t Panic and make sure you write an answer for each question, even if it is a guess!
