What fraction of our diet should be fruit and vegetables?
One third
What option is good to keep optimum nutritional value and prevent waste?
Frozen fruit and vegetables
Why is it important to get a variation of fruit and vegetables in our diet
Because different fruit and vegetables have a range of vitamins and minerals which are important to keep our body functioning the way it should
What does Polly polyphenol oxidase do to fruit and vegetables
Causes brown pigment to develop also known as enzymic browning
Enzymatic browning is common in which fruits?
Apricots, apples, bananas and grapes
Enzymic browning is common in which vegetables?
Potatoes, lettuce and aubergines
What reaction occurs when a fruit or vegetable is cut into and oxygen has access to the inside of the fruit or vegetable?
Enzymic browning
Give three ways to prevent enzymic browning
- Placing the fruit or vegetable in the water and salt- salt is a preservative
- Covering in acid for example Lemon juice or vinegar-it has an alkaline affect when used with vinegar which delays oxidation
- Place in water and vitamin C tablet-crushed vitamin see tablets contain high levels of citric acid which can prevent or delay oxidation of fruit and vegetables and Enzymic browning
Give some examples of ways you can process fruit or vegetables
Pre-prepared fresh Canned, bottled or tinned Frozen Dried Juiced
Give reasons for processing fruit or vegetables
Convenience
Year round availability
Increased shelf life
Preference
Give examples of primary processing
Picking Cleaning Sorting Transporting Grading Weighing Refrigerating
What is the definition of primary processing
The conversion of raw materials into food commodities. The physical form changes very little.
Give examples of secondary processing
Chopping Boiling Baking Mixing Freezing Canning Drying Cooking
What is the definition of secondary processing
Converting primary processed food into other foods. Turns primary processed food into other food products either on the own or mixed with other ingredient. The physical form can change quite significantly.
What does preservation mean
A process of treating or handling food that slows down the spoilage or loss of quality of food, and extends the time or shelflife when it can be eaten safely
Describe spoilage
Food going ‘off’; they include the food going brown or black, wrinkly, mushy ect. It is an increase in bacteria or fungi
You four signs that a food might be going bad
Wrinkly
Slimy
Smelly
Difference in taste
Why and when my preservation be useful
Increases the shelf life (keeps longer before you use it)
Use where a glut food, so none goes to waste eg. Around harvest time eg. Apples, pears, onions, beans, berries, herbs
In green fruit and vegetables what is present that makes it that colour
Chlorophyll
What affect does cooking have on green fruit and vegetables
Colour and some nutritional value is lost
If chlorophyll is present in a fruit or vegetable what colour will it be
Green
If a green fruit or vegetable is acidic what kind of green will it be
Dull, olive green
If a green fruit or vegetable is alkaline what type of green will it be
Bright green

Carotenoids
What affect does cooking have on yellow and orange fruit and vegetables
no affect
If carotenoids are present in a fruit or vegetable what colour will it be
Yellow or orange
What water soluble pigments my fruit and vegetables red or blue
Anthocyanins
How do you anthocyanins react to a neutral pH
It will make the fruit or vegetable purple
How do anthocyanins react to an acidic pH
It will turn the fruit or vegetable red
How do anthocyanins react to alkaline pH
The fruit or vegetable will turn blue
What affect does cooking have on red or blue fruit and vegetables
They’re very soluble in water so colour is lost easily
What is produced during photosynthesis
Glucose and oxygen
What is needed for photosynthesis to take place
Carbon dioxide, water and light energy
What is the first stage of photosynthesis
Plant uses water CO2 and energy from the light
What is the second stage of photosynthesis
Starch (glucose) production. This is converted to starch
What is the third stage of photosynthesis
Fruit ripens. Glucose (starch) is converted into sugars-sucrose
What is the fourth stage of photosynthesis
Fruit ripens further. Sucrose is converted to fructose.
What fruit or vegetables can you bake
Potatoes
Apples
What safety precautions do we need to take when baking fruit and vegetables
