Wheat Processing

Question 1

What term is used to describe the processing of wheat to produce wheat flour

Answer 1

Milling

Milling of wheat

Question 2

What are the two stages involved in wheat processing?

Answer 2

Stage 1: Wholemeal flour production

Stage 2: White flour production (refining process)

Question 3

What two processes occur during stage 1 of the milling of wheat?

Answer 3

Preparation

Milling

Question 4

What two processes occur during the preparation stage of wholemeal flour production?

Answer 4

Screening

Cleaning

Question 5

What occurs during the screening stage of wholemeal flour production?

Answer 5

Sieves remove sticks, stones, dust, soil and dirt from the wheat grains

Question 6

What occurs during the cleaning stage of wholemeal flour production?

Answer 6

Wheat grains are scoured to remove the beard and are then washed

Question 7

What three process occur during the milling stage of wholemeal flour production?

Answer 7

Conditioning
Blending
Break rolling

Question 8

What occurs during the conditioning stage of wholemeal flour production?

Answer 8

Water is added to wheat to make it easier to roll and mill

wheat is often too dry for milling without adding water

Question 9

What occurs during the blending stage of wholemeal flour production?

Answer 9

Different wheat types are blended to create a blend called grist

Question 10

What occurs during the break rolling stage of wholemeal flour production?

Answer 10

Wheat grains are passed through rotating metal ridged rollers that peel them open, releasing the endosperm without breaking the outer bran layers into pieces
(This is wholemeal flour)

Question 11

What is mnemonic for remembering the processes that occur during stage 1 (wholemeal flour production) of wheat processing?

Answer 11

Starchy 
Cereals 
Can 
Be 
Beneficial

Question 12

List all the processes that occur during stage 1 of the milling of flour
(5)

Answer 12

Screening 
Cleaning
Conditioning  
Blending
Break rolling

Question 13

List the processes that occur during stage 2 of the milling of wheat (white flour production)
(5)

Answer 13

Sifting 
Rollers 
Air classified 
Addition of additives 
Packaging and labelling

Question 14

What occurs during the sifting and purification stage of white flour production?
(3)

Answer 14

The opened wheat grains pass through a series of rotating sieves, starting with a coarse mesh sieve to separate the bran and germ from the rough endosperm (semolina)

Air is blown through the grain to help separate the lighter particles (brain) from the heavier particles (rough endosperm)

The bran and germ can now be packed and sold separately

Question 15

What occurs during the rolling stage of white flour production?

Answer 15

The remaining endosperm is grounded by smooth steel-reducing rollers to produce fine flour

Question 16

What occurs during the air classification stage of white flour production?

Answer 16

Air is introducing to the fine flour to create a lighter flour
(The flour is air classified)

Question 17

What occurs during the addition of additives stage of white flour production?
(3)

Answer 17

Bleaching agents such as calcium carbonate are added to whiten the flour

Nutritive additives such as calcium are added to replace the nutrients lost during milling

Improvers such as vitamin C are added to improve the quality of the gluten in the flour

Question 18

What occurs during the packaging stage of white flour production?
(2)

Answer 18

Flour is weighed to retail size such as 1kg or 2 kg

Flour is packaged into varying materials such as paper or cardboard

Question 19

What occurs during the labelling stage of white flour production?

Answer 19

The packaging is labelled with details including the type of flour, ingredients, storage instruction, allergy advice and nutritional information
