2. (a)(i) Why is it important to research existing
products before starting to
design new products?
• To see what is already on market/on sale
• Ensure what you make will meet with current
consumer needs
• To identify good features you will want to keep
• So you can improve on/identify weaknesses of
products already on sale.
• Get inspiration for new product/use customer
reviews
• Identify prices
• Identify competition
• Look for gap in the market
2. (a)(ii)
A computer could be useful to research existing products :
• using internet searches/websites
• Spread sheet storage/ interrogation of sales figures
• Email other suppliers/manufacturers
• Looking at images of food products on sale as secondary
research
• Greater capacity for searching the market
• Comparative product analysis is easier/quicker
• Using on line surveys/questionnaires/email with target
consumers
• carrying out nutritional analysis on products
• working out potential costs/ scaling up implications
• Saves on travel time/expense give advantage
• Facility to show research results neatly presented
• Information/data gathered can be stored for later use
• Can predict future trends
• More accurate than human searches
(ii) meeting the cultural needs of competitors
from other countries
• cultural flavours
• traditional recipes and ingredients
• may give examples of specific spices /
flavours used
• foods linked with specific country e.g. British
. potatoes,
Chinese . rice
• ingredients used to cater for different
religious beliefs, e.g. halal or
kosher meats
• no meat content for vegetarian consumers
due to religious beliefs
e.g. Hindus no beef, Muslims no pork

the products below.
Give a detailed reason for your choices.
1. Fat for pastry
2. Sponge cake
3. Well risen loaf of bread
Understanding ingredients in products
Sponge Cake
Choice: sugar; castor sugar
(1 mark)
Reasons:
•Finer grain
• Easier to cream
• Smoother texture
• Larger grains may give
speckled texture
Fat for pastry:
• Choice: fat butter /
margarine lard /
mixture

• Adds colour
• Adds nutritive value / vit
AD
• Adds to shelf life
• Shortening properties
Understanding ingredients in products
Well risen loaf of bread

(a) How are these ingredients suitable for
consumers choosing a
healthy option product?
• Wholemeal flour – high fibre, energy, iron, Vit B
• Sweeteners – reduced sugar content
• Polyunsaturated margarine – lower in saturated fats, heart
disease, lower in cholesterol
• Skimmed milk, Low fat yoghurt – lower in fat, lower
cholesterol, lower calories
• Eggs – protein, Vit A D, iron.
• Blueberries – fruit portion towards 5 a day, some Vitamin C,
fibre

disease, dental caries, obesity, digestion, cancer etc
(b) What are the advantages of using tunnel ovens when
baking
batches of biscuits?
consistency of outcome
• process can be timed accurately
• even colour for biscuits
• CAM more efficient than using human
workforce/to make
large quantities
• less human input due to computer control/
less human error
• different temperatures can be set for
different stages of
production
• cost effective after initial set up
• some tunnel ovens lead into cooling towers
at the end for
rapid cooling / saving time
• continuous flow for large scale production

(ii) Explain what happens to the egg whites
when they are
whisked.
(iii) Explain what happens to the whisked egg
whites when they
are cooked.
(ii) Explain what happens to the egg whites when they are
whisked.
• A foam is formed when air is mixed into egg white
• egg protein stretches to hold larger air bubbles
• aeration takes place
• surface tension breaks down
• egg white (albumin) denatures/breaks down
• the foam becomes white, stiff, smooth and light textured
• heat generated from whisking partially coagulates
mixture.
(iii) Explain what happens to the whisked egg whites when they
are cooked.
• foam remains stable (does not rise)
• gives fine, solid mesh structure
• protein coagulates/sets
• coagulates at 60C
• longer time at lower temperature gives a whiter, drier
meringue.
• shorter time at higher temperature gives a browner, sticky
and pliable meringue.

crystallised/caramelised sugar, peel
etc.
• Add icing e.g. Chelsea buns, iced buns
5. (a)(i) Explain why consumers choose to buy takeaway products
instead of
making the food themselves.
Lack of skills
• Lack of time and effort / busy lifestyles make takeaways
convenient as instant foods little cooking or preparation needed.
• Quick and easy
• Availability of take away foods
• Prefer tastes of takeaway
• Convenient for gatherings/special occasions/parties
• Wide selection of multicultural options available
• Consumer may lack skills needed /Food expertly cooked by
specialist chefs with knowledge of special equipment/methods
etc.
• Some takeaways specialise in different dietary needs and can
be
helpful for consumers dealing with different needs. E.g gluten
free.
• Takeaways may prove cheaper than buying all ingredients
needed.
• less clearing up/washing up
• Other relevant answers
5. (a)(ii) Explain some of the disadvantages of takeaway foods.
• Often seen as unhealthy/often high in fat and salt
• Some takeaways thought to contribute towards health
problems/not helpful for consumers wanting healthier options
• Packaging to deal with
• Price considerations: Expensive to buy, but some can be
cheaper
than buying individual ingredients to make at home.
• Often use artificial additives
• May need to travel to buy
• May not have what you like
• No control over outcomes/ do not know what goes into the
food
• Often use large number of additives/e numbers which can be
detrimental to health
• Cannot guarantee freshness/quality
• May cause food poisoning if not cooked/stored/reheated
safely or
hygienically
• No control over source of foods/suppliers
• Some people e.g. young generation are over reliant on
takeaways
and therefore do not learn cooking skills.
(c) Explain why some control checks are done by
computers.
• saves manufacturer time
• less staff
• more reliable / accurate / consistent
• less human error
• easier for monitoring
• alerted immediately if problems
• credit specific examples e.g. for temp, time, control,
weight
checks, PH, metal detection
7 (a) Explain why colour coded equipment is used when preparing
beefburgers.
• Prevents cross contamination
• Colour coded knives / boards allow different foods to be prepared
separately
• May give colours used for raw meat (red) cooked burger (yellow)
/ vegetables (brown) / bread (white) / fish (blue) / salad (green)
• Keeps foods apart so that bacterial infection not at risk
• High risk foods kept separately
