GCSE Flashcards
Explain what the term food provenance means
Food provenance means knowing:
How food was transported
How food was produced
Where food was grown, raised or caught
Explain how food provenance helps costumers when shopping for food
Allows customers to chose specific products eg N Ireland pork
Assists consumers in eating a more seasonal diet eg strawberries in the summer months
Purchasing from farmers markets enables consumers to engage directly with producers
Increased access to information about where food comes from and assurances that it is safe to eat (food security) allows food to be traced from farm to fork (food traceability)
Identifies the origin of the food eg comber potatoes
Protects the environment eg organic crops which are not sprayed with pesticides
Increases food knowledge - consumers may become more aware about how their food is grown, reared or caught
Maintains food culture - foods that are traditional to NI include potatoes, soda bread, wheaten bread
Develops a more sustainable food system - this applies to eg fishing where quotas are limited to ensure the fish can survive to breed and provide food in the future
Improves animal welfare eg free range eggs

State the 9 steps involved in growing plant crops
1 - preparing soil - loosen it 2 - sowing seeds 3 - watering 4 - fertilising (nitrogen + manure) 5 - weeding 6 - protecting from pests (poly tunnels - bad weather) 7 - harvesting 8 - separation and inspection 9 - storage
Give six facts about rearing beef animals on a farm
2 years old they go to abattoir
Animals wear ear tags - certain numbers
In summer beef animals go to grass
In winter they are fed barley oats, sugarbeat, vitamins + minerals
In winter cows eat preserved grass silage
They eat 30kg of food and 50L of water each day
Outline the characteristics of intensive farming
High yield crop
Pesticides used to control weeds and pests
Chemical fertilisers used to enrich soil
Animals kept indoors with minimal space
Mechanised agriculture
Outline the characteristics of organic farming
Crop rotation linked to seasons Hand weeding and natural pest control Green manure and composting to enrich soil Animals are given space to move freely Labour intensive agriculture No growth hormones are given
Outline why some consumers buy organic food
It helps the ecosystem because the manufacture of nitrogen based fertilisers produces large amounts of greenhouse gases
It is perceived as healthier as there is no chemical fertilisers pesticides or herbicides used in production
It is better for the animal
It sounds and looks more natural
People copy influencers/ celebrities
They perceive it as more nutritious
Land is well cared for and allowed to be more natural
GM crops are not allowed on farms like this
Define farm to fork
Traceability from the farm to the fork and plate
Define primary industry
An industry that harvests raw materials from nature, including agriculture and fishing
Define organic farming
A type of farming that focuses on producing food in ways that minimise harm to the environment or animals
Define intensive farming
A large scale operation where profitability and efficiency are priorities
Define yield
The produce of a crop
Define pesticide
A substance that destroys pests

Give the main methods used to catch fish
Dredging
Pots and creels
Line caught
Trawling
Explain how dredging works
Dragging metal framed nets with fakes attached through the sea bed to release species of shellfish that linger at the bottom of the sea floor. Target species are caught in the dredging equipment and winched onto the deck of the boat to be emptied
This method can can have significant impact on sensitive sea floor habitats and bottom dwelling species. A way to reduce this is to limit the areas where dredging can occur
Examples of fish caught by dredging
Clams Cockles Mussels Oysters Scallops
Explain how trawling works
Drawing a net towed by a boat around a targeted school of fish. Trawling is often restricted to planned areas as the heavy gear can damage sensitive seafloor habitats. Unwanted fish are thrown back into the ocean
Examples of fish caught by trawling
Cod Habitat Lobster Shrimp Tuna
Explain how pots and creels work
These are cages or baskets that hold species alive until fishermen return to haul in their catch. They have one or more openings and are used with or without bait. The second opening allows fish or species that are below the legal catch size to escape. They’re usually placed on the sea floor, but some are designed to be in midwater. Sometimes whales can become entangled and this is a serious conservation concern in some pot fisheries
Examples of fish caught by pots and creels
Lobster and crab
Explain how line fishing works
Large scale or small scale using baited hooks. This system uses either a single fishing line, hook and bait or a mainline with several branch lines with baited hooks, which are then reeled in manually or mechanically. A jig is a type of grappling hook, which is attached to a fishing line
Examples of fish caught with jigging
Tuna
Cod
Macherel
Define sustainability
It is about producing and consuming food that protects the environment and economy
What are sustainable fishing practices designed to do
Maintain dish stocks and establish a healthy marine ecosystem for the future
Minimise the impact on our environment by managing fishing activity carefully so that other habitats wishing the ecosystem are healthy eg sharks, dolphins and seals
Manage fisheries effectively to ensure that they comply with legislation and adapt to environmental change
Ensure that people who depend on fishing can maintain their livelihood
What are open systems in terms of fish
Where the fish are contained in more natural bodies of water such as pond or sea enclosure
What are closed systems in terms of fish
Where the water is artificially recirculated
What does the bottom culture involve in terms of fish
Growing mussels, oysters, scallops and clams on the seabed and harvesting them by hand, raked or dredging. Seaweed may also be grown from bottom culture
What is aquaculture
Were fish are farmed
Define food processing
It refers to the stages by which raw ingredients are turned into food and made suitable for consumption
Why is food processed
Make it safe to eat Preserve it and slow down spoilage Maintain its consistency Add variety to the diet Make it enjoyable to eat Make it easier to prepare and serve Make it available out of season Reduce time spent on meal preparation at home

Outline the stages in the primary processing of wheat
Wheat is grown in field
Harvesting process removes wheat grain
Harvested wheat grains are stored until use
Wheat is transported to a mill
Wheat is cleaned + conditioned
Wheat is milled using range of rollers + sieves
Wheat germ, endosperm are separated then blended into different flour
Flour is sold in shops for home baking but also as bread, cakes, pasta etc

Brown flour - 85% - some bran + germ
White flour - endosperm only
What is the function of yeast in bread making
Make bread rise to produce CO2
Which ingredient helps the bread to form and hold its shape
The flour proteins in it form gluten which help to make the shape of bread
Describe what is meant by the term ‘proving’
Rest period to allow final rise before baking
Outline the stages in primary processing of milk
Milked twice a day
Stored at 4 degrees, transported for processing at a dairy
Pasteurisation- heated to very high temperature to destroy pathogenic bacteria
Separated into cream and liquid components
Reblending - amount of cream added depends on type of milk
Homogenisation - pushed through a hole at pressure so large fat molecules are broken down + dispersed evenly
Give the fat content in each type of milk
Blue - 3.2-3.8%
Green - 1.5-1.8%
Red - 0-0.3%
What is pasteurisation
Heat treatment where milk is raised to high temperatures then cooled quick to packaging
Why is pasteurisation used
Makes milk safe to drink
Prolongs shelf life
How is milk pasteurised

Which piece of equipment is used to heat and cool the milk
Heat exchanger
Identify 3 well known diary foods which are made from milk
Cheese
Cream
Yoghurt
What is the term to describe the diet followed by someone who has an intolerance to cow’s milk
Lactose intolerant
Outline the processes used in secondary processing - milk into cheese
Milk pasteurised the cooled rapidly to be pumped into large cheese vats. ‘Started cultures’ which are harmless bacteria, are added to ‘ripen’ the milk and give the cheese it’s flavour
Rennet (an enzyme) is added which makes the milk separate into thick curds and runny whey
Curds are cut which helps to release the whey
The curds and whey are heated and stirred. Soft cheeses do not need to be stirred for long. Eventually the whey is drained off, leaving the curds. Once the curds are separated different processing method are used, depending on the type of cheese.
The furs are then stacked, cut and turned to release more whey. This process is called ‘cheddaring’. Salt is added and the cheese is cut into tiny crumbs before being packed into a mould and pressed. The cheese is removed from the mould, wrapped and stored. The longer a cheese is stored, the stronger the flavour. Some cheese is stored for up to 2 years.
Give 3 reasons why salt is added to the cheese
Preservation
Flavour
Help to expel whey as the curds shrink as they are dry

State facts about tartrazine
It exacerbates the symptoms of asthma in children or skin rashes, nasal congestion and hives. It’s chemical number is E102. It is a synthetic yellow due. It is found in fizzy drinks, fruit squash, fruit cardial, cake mixes soups, sauce and ice cream. These are many foods liked by children
Give 2 arguments for fortification
It helps to achieve optimum nutrient intakes for general population. It is convenient as products only need to be consumed in small quantities and often
Fortifying foods helps those with special dietary requirements eg folic acid in white flour helps reduce neural tube defects such as spina bifida
Give 2 arguments against fortification
Some nutrients may be already present in the right quantity in the consumer’s diet and therefore fortification is not necessary
Potential risk of ‘over-dosing’ on some nutrients if fortified food is over eaten
