Unit 1 and Unit 2 Flashcards
Define food Provence
The origin of food: where it comes from
Define Food Additives
Natural or synthetic substances added to food to perform a particular function.
6 examples of food additives and their function
Antioxidant- extends shelf life
Colours - make food look attractive
Emulsifiers - helps to mix ingredients together and stop them separating during storage
Flavourings - replace flavours lost during processing
Preservatives - keeps food safe to eat for longer.
Sweeteners- used instead of sugar to make food taste sweet
Define food fortification
Nutrients added to food during processing.
Reasons why food is fortified
To replace nutrients lost during processing
To display for marketing purposes
To cater for individuals with certain dietary needs such as vegans
To prevent deficiency disorders

What is a natural additive and give an example.
Natural additives are substances naturally found in food products that are extracted from one food to be used for another, for example beetroot juice can be used as an additive for sweets to enhance their purple colour
What is a nature identical additive and given an example?
These substances are man-made copies of those that naturally occur in food products, for example benzoic acid is found naturally but it’s also synthetically made and used as a preservative
What are artificial additives and give an example?
These substances are synthetically made and are not naturally finding any food products for example Saccharin is an artificial sweetener
Name the five characteristics of intensive farming
High yield crops
Pesticides used to control weeds and pests
Chemical fertilisers used to enrich the soil
Animals kept indoors with limited space
Mechanised agriculture
Name five characteristics of organic farming
-Crop rotation link to seasons
-Hand wedding and natural pest control -Green manure and composting to enrich the soil
-Animals are given space to move freely
-Labour intensive agriculture
Describe the three main methods for catching fish and given an example of a type of fish caught each of these ways
Dredging- dragging metal frame nuts with rakes attached through the sea bed.
(E.g. mussels)
Linecaught- large or small scale using bated hooks (e.g. mackerel)
Pots and Creeks- these are baited with fish and placed on the seabed to be collected later (e.g. crab)
Describe the concept of protein complementation
A combination of low biological value proteins in one meal to provide all the essential amino acids
What is LBV and HBV?
Low biological value
high biological value
Explain why the body needs energy
Physical activity
Maintaining body temperature at 37°
Bodily function such as heartbeat, breathing and digestion
Growth and repair of body tissues
Meeting the body specific needs (e.g. during pregnancy, lactation and recovering from illness)
Explain two functions of protein
Growth and repair
Maintenance of body tissue
Differentiate between dispensable and indispensable amino acids
Dispensable amino acids are made in the body but indispensable amino acids are not and have to be intaken from the diet
Evaluate the use of additives in food
Additives in food can provide a range of advantages such as extend shelf life and intensify flavour in food however people may want their food to be natural

State three disadvantages of additives in food
Potential health risks
Nutritional impact The additives may enhance the food, but the food will still lack essential nutrients
Misleading quality perception Making food appear more fresh than it actually is
Disadvantages of fortifying food
Risk of over consumption
Masking poor diet
