Food Provenance and Food Waste Flashcards
Proccess of making cheese
1) Raw milk is pasteurised to kill off pathogenic bacteria
2) friendly bacteria added to thicken milk and make it sour
3) Rennet from calf stomach is added
4) Rennet causes milk to coagulate into solid cheese curds, surrounded by the remaining liquid (whey)
5) Whey removed through draining/ cutting/ coking/ salting/ stacking cheese curds
6) Cheese curds pressed to form blocks of cheese
7) Blocks of cheese placed in temperature controlled storage to mature and develop taste and texture
8) Bacteria/ moulds may be added to change flavour
Which type of flour are certain vitamins minerals (e.g niacin and B1) naturally present in
Wholemeal flour
(They are lost during the production of white flour but then re added back in afterwards by law)
What do preservatives prevent from growing that make the food last longer
Bacteria
4 examples of natural food preservatives
Sugar, salt, vinegar, lemon juice
Red tractor symbol meaning
Producer meets standards of food safety, hygiene, animal welfare and environmental protection and can be traced back from the farm that they came from in the UK
Fairtrade symbol meaning
Farmers receive fair and safe working conditions and pay
Soil association organic food symbol meaning
Product is 100% organic with no pesticides or fertilisers used and the product works with nature
Rainforest alliance food logo meaning
Product produced by means of Social, economic and environmental sustainability
Describe intensive farming including positives and negatives
Large scale farming that Uses machinery and fertilisers/ pesticides to maximise yield produced
More food security as higher crop yield
Cheaper production so cheaper to buy
Less jobs
Fertilisers and chemicals can harm wildlife
Describe organic farming and positives and negatives
Farming without use of chemicals or pesticides
More sustainable
Works with environment
Lower crop yield so less food security and more expensive to buy
2 types of farming
Organic
Intensive
What are GM (genetically modified) foods
Foods that have had their genes altered to give them useful characteristics e.g changing colour and improving growth
Why can GM crops produce a larger yield
Genes altered of crop to become pest resistant so less crops eaten and damaged by pests
Advantages of GM foods
Grow quicker
Higher yield (pest resistant)
Cheaper to producer and for consumer to buy
Can be altered to have a longer shelf life so less food wasted
Can be modified to contain extra nutrients
Can ripen earlier so available for longer in the year
True or false, GM foods can be modified to improve nutrient levels
True
Advantage in improving nutrition levels especially for poorer countries
True or false, GM foods are cheaper
True
Pest resistant so large crop yield so makes production cheaper therefore market price cheaper
Disadvantages of GM foods
Not yet aware of any long term health affects as they are quite new
Concerned modified genes could cause wider problems e.g if a weed got the weed killer resistant gene it would cause it to become indestructible
True or false, all GM foods must undergo strict safety assessments
True
Why must all GM foods undergo strict safety assessments
To ensure their are no known health risks
To ensure the genes aren’t messed with in a way that could be harmful
What type of GM foods must be clearly labelled
If they contain more than 1% of GM ingredients
foods that contain more than what % of GM ingredients must be clearly labelled
1%
True or false, factory farmed animals are a form of intensive farming
True
It aims to increase yield by having more animals to get foods from
What are conditions like for factory farmed animals
Can barely move as not much room
Warm conditions to reduce energy through moving/ trying to keep themselves warm- more energy goes into producing meat/ eggs for maximum food production
Animals often given growth hormones/ are force fed to make it quicker and cheaper to produce the meat
Concerns around factory farmed animals
Ethical- animals treated very badly, are likely to suffer from diseases, are killed at a young age and can’t behave naturally
Meat isn’t as good quality
Why are factory farmed animals in warm conditions
Animals don’t waste energy trying to keep warm- more energy can go into producing meat so it can be done quicker and maximises food production
True or false, factory farmed animals are force fed and can be given growth hormones
True
Speeds up their growth so produce meat quicker
Conditions for free range animals
Animals have more space and are free to roam
No hormones given to speed up growth
Higher standard of welfare (proven by food logos e.g free range eggs)
Why are free range animal products more expensive to buy
Production process is more expensive as animals lose more energy moving around so take longer to grow and produce the meat/ eggs
More land for them to roam in costs more
2 types of fishing methods
Trawling
Fish farming
Trawling meaning
Method of fishing
Fishing boats catch fish with nets- some drag net through open sea, some drag net along surface of seabed, some use a metal basket instead of a net
Fish farming meaning
Method of fishing
Fish raised in tanks/ cages with overcrowding and high levels of disease
E.g salmon
3 key reason why food is wasted
Spoiled (gone off, overcooked, burnt, not stored correctly, passed use by date, not kept at right temperature etc)
Too much food (not needed due to cooking too much, not controlling portions, not following a shopping list etc)
Incorrect food preparation e.g peeling vegetables too thickly so lots is thrown away
Reasons why food retailers waste food
1) imperfect food (don’t want to sell it If it’s wrong shale/ size)
2) get too much food to avoid running out or stock
3) offers- encourage people to buy more than they will use
4) larger packs of food are better value for money but normally not all used
Benefit of plastic packaging
Transparent- can see product inside
Flexible shape- takes up less storage room so easy to store and transport
Lightweight
