•More occasions being celebrated
•Easily available – Supermarkets often have a wide
range available
•Lack of practical skills
• Programmes such as British bake off
• healthy option products available
• meet different consumer budgets and needs
Fat and sugar ingredients are
melted in a saucepan
Texture tends to be much
heavier than other cakes and
wont rise much
Bicarbonate of soda can be
used to create a lighter texture
Eggs and sugar whisked together to trap
air (aerate)
Rubbing -in (More flour than
fat)
Ingredients:
200g plain flour
100g margarine
100g caster sugar
2 eggs
30ml milk
2teaspoons baking
powder
Air is trapped in the sieving
the flour and by lightly (with
finger tips) rubbing the fat in
to the flour.

Q-What are the causes of the following problems during the production of muffins?
Problem
Cause
A piece of metal is found in a cooked muffin.
Lack of personal hygiene by workers – no jewellery, hair pins
Quality checks have not taken place
Metal from packaging not checked
Machinery faulty/Poor maintenance of machines
Faulty metal detector
Fruit pieces in a cooked muffin have a dry texture.
Stale fruit used
Insufficient liquid
Muffin cooked too long
Too high a temperature used.
Excess fruit used on topping
Poor quality control
Cooked muffins are an uneven size.
Poor portion control
Modified Starch
Modified starch is classified as a smart food and is used by manufacturers in a
variety of products.
It is a starch that has been altered to perform additional functions.
In pizza toppings – topping thickens when heated in the oven and will not run off
the pizza.
Pre-gelatinised starch is used to thicken instant desserts without heat. Cold liquid
such as milk can be added and the dessert will thicken.
Sauce/gravy granules – boiling water can be added to thicken without the sauce
going lumpy.
Modified starches are used to thicken low calorie salad dressings, as they are not
affected by the acidity.
Modified starch is used as a fat replacer in low-fat meals.
Modified starches allow sauces to be reheated with no sineresis. *
This is
useful in dishes that are cooked from frozen e.g. lasagne.
The noodles in ‘pot snacks’ are pre-gelatinised; so boiled water will reheat and
‘cook’ them.
Modified starch is used in ‘cup-a-soups’ to improve mouth-feel, thicken the
drink/soup when the boiled water is added, and blend uniformly without lumps.
Sensory Testing in Manufacture
Sensory analysis is used at several stages during product development
Companies can compare a
competitor’s product
Improve products by modifying or changing the ingredients
Check that the specification is being met
Monitor quality control by checking regular samples against specification
Detect differences between products from different runs or batches
Profile the characteristics of new products
Describe specific characteristics
Demonstrate new products to marketing team
Promote new or reformulated products to consumers
Sensory analysis is carried out in controlled conditions
Sensory analysis is used in industry and
discovers details on:
Flavour
and taste
Texture
– Colour, shape, size
Smell/Aroma
Sounds
Methods of Sensory Testing
Appearance
Product Profile - STAR
PROFILE DIAGRAM
Allows food products to be
evaluated using a range of
attributes
Evaluate differences in similar
products
Gauge consumer response
Analyse specific attributes
Check a product meets its
specification
Compare similarities in a range of
products
Show opportunities for product
development

Environmentally friendly packaging causes less damage to
the environment. There are three types:
•Reusable packaging can be cleaned and re-used. For
example, glass milk bottles are reused.
•Recyclable packaging is made of materials that can be used
again, usually after processing. Recyclable materials include
glass, metal, card and paper.
•Biodegradable packaging will easily break down in the soil
or the atmosphere.
Recyclable packaging should carry standard symbols that show
what the product is made from and how it can be recycled
Farm Assured
You need to
know
advantages &
disadvantages
Animals must have been looked after to a certain
standard of welfare & safety, must be British,
standards set by Government
Organic
Fair trade
Is an organized social
movement and marketbased approach that aims
to help producers in
developing countries earn
a liveable wage. Allowing
farmers to educate their
children and improve
their standard of living.
Organic foods are made according to certain production
standards. The use of conventional non-organic pesticides,
insecticides and herbicides is greatly restricted and avoided as
a last resort. However, contrary to popular belief, certain nonorganic fertilisers are still used. If livestock are involved, they
must be reared without the routine use of antibiotics and
without the use of growth hormones, and generally fed a
healthy diet. In most countries, organic produce may not be
genetically modified.
Food Miles
People are concerned about the environment, food miles is about the
amount of C02 that is produced in the delivery of products e.g
strawberries from Spain, buying locally grown means there are less
food miles
What is a hazard?
In food products, a hazard is anything that
can harm a customer. A hazard may be:
Physical
Chemical
Biological
Hair
Metal
Dirt
Pesticides
Cleaning products
Insecticides
Bacteria
Mould
What is a critical control point?
A control point is the step in the making process where hazards must be controlled. This step has
to be carried out correctly to make sure that the hazard is removed or reduced to a safe level. The
hazard may be chemical, physical or biological. Some hazards are high risk and the control points
for these hazards are called critical control points as it is critical (essential) that the hazard is
removed or reduced.

How do food manufacturers inform consumers about healthy
eating guidelines
• Labels on packaging, which may also give dietary advice etc,
Use the traffic light system and give nutritional charts
• Show portion size recommended on packaging.
• Advertisements in magazines / on television
• Use of websites
• Special claims on packaging
• Other relevant points accepted
Colour-coded nutritional information, as shown
in the image above, tells you at a glance if the food
has high, medium or low amounts of fat,
saturated fat, sugars and salt.

Most of the major supermarkets and many food manufacturers choose to display
nutritional information on the front of pre-packaged food and drinks.
There are two major schemes for front-of-pack labelling in place: traffic light
labelling and Guideline Daily Amount (GDA) labels. Some packs may use a
combination of the two.
‘Best before’ dates appear mostly on foods that are stored ambient (in a cupboard)
Products such as biscuits, crisps, bread will have this date. when the date runs
out it doesn't mean that the food will be harmful, but it might begin to lose its
flavour and texture e.g. Biscuits may be softer and less crunchy
‘Use by’ dates are generally on products that need to be stored in the fridge, to
reduce the growth of bacteria, products such as meat and cream. You should
not eat these products after the ‘use by’ date as you could become ill.
Carbohydrates
Uses of starch:
Bulk ingredient: main ingredients for many
products e.g. cakes, bread
Thickening Agent: cornflour used to thicken
through gelatinisation e.g. sauces & gravy
Starch gelatinizes when heated in a liquid, producing a
thickened liquid
Heat
starch
granules
in liquid
Starch
granules
burst
Starch
granules
become
swollen
SSss
The liquid
thickens
and
gelatinizes
Faults in Sauces:
Too thick= inaccurate weighing
Lumpy = not continually stirred, extra flour added that was
not blended in liquid first
Poor colour = flour burnt on bottom of saucepan, metal spoon
used to stir
Bland= not enough flavouring, mild cheese used
Modified Starches:
This is a starch that has been altered to react differently:
• Modified starch used to thicken food with boiled water
e.g. Cupasoup
• Pre-gelatinised starch used to thicken with a cold liquid
e.g. Angel delight
TWO TYPES:
Starch found in flour, potatoes, pasta, rice
Sugar found in fruit, drinks, sweet baked products
Uses of Sugar:
Sweetens: improves flavour making sweeter
Preserves: In jam, large quantities prevent bacteria from growing
Adds colour: sugar caramelises when heated turning golden
brown
Aerates: when beaten with butter or egg helps to trap air
Stabilises: with meringues it strengthens the foam
Bulks: gives texture to food like ice-cream & cakes
Types of Sugar:
Granulated: general purpose used: sweetens drinks
Caster: small crystals used: dissolves better in cakes
Icing: Fine instantly dissolves used: for icing sugar
Demerara: Large light brown crystals used: top of puddings
Muscovado: Dark brown & sticky used: fruit cakes
Artificial sweeteners can be used to create ‘low calorie’
products also better for teeth and makes product suitable
for diabetics
HOWEVER:
Can leave bitter after taste
Can lack bulk in recipe
Reduces shelf life
