Module 1

Processing

PRIOR KN0WLEDGE

  1. This module involves the changes that one type of material or several types of material can undergo to form a new product. We call this PROCESSING. In this module we will look specifically at processing FOOD. A variety of ingredients are needed for the purpose.

Examples of processing

Ingredients used Processing New Product
sweet corn, cream, milk, flavourants add, simmer, stir soup
eggs, milk, flavourants, butter melt, beat, add omelette
eggs, sugar, butter, milk, flour, cocoa, salt, baking powder, essence beat, add, melt, sieve, fold in, add, mix, place in, bowl, turn out a chocolate sponge cake

Assignment

  1. COMPLETE ON YOUR OWN:
  1. Use any recipe book or a magazine with recipes. Select any recipe and completeyour own table:
  2. Write down all the equipment that you need to prepare your product:

Source of reference:

[LO 2.2]

Assignment

  1. Use any explanatory dictionary and write down the meaning of each of the following processes for preparing food:
  • blanch .
  • chop .
  • beat .
  • marinate .
  • decorate .

Source consulted: …………………..

Can you think of other processes? Write down as many as you can:

[LO 1.3]

  1. When we prepare food, we call the materials we use ingredients . These can be vegetable (from plants) or animal (from animals). Go home and open your mother’s food cupboard and fridge. Complete the following table by writing down at least five examples of each.
VEGETABLE INGREDIENTS ANIMAL INGREDIENTS
e.g. Flour Milk
  1. These ingredients must be stored in the most suitable packaging so that the food can retain its nutritional value for as long as possible, and does not dry out, become moist or start to smell bad .

[LO 1.2]

Link each type of food with the most suitable packaging to ensure the above:

TYPE OF FOOD PACKAGING
  1. Flour
Plastic bag
  1. Bread
Tin
  1. Milk
Polystyrenecontainer
  1. Butter
Airtight container
  1. Cannedsardines
Plastic bottle
  1. Gravy powder
Cardboard box
G Apples Plasticcontainer
H Canned peaches Paper bag
I Pizza Flat carton
Tin

[LO 2.2]

  1. MEASURING UNITS FOR INGREDIENTS

Assignment

In what unit would you measure the following ingredients and what equipment would you use? Circle the correct answer.

INGREDIENT UNIT EQUIPMENT
  1. milk
mℓ, g measuring jug/scale
  1. sugar
mℓ, g measuring jug/scale
  1. baking powder
mℓ, g measuring jug/scale
  1. butter
mℓ, g measuring jug/scale
  1. vanilla essence
mℓ, g measuring jug/scale

Conclusion:

Fluids are usually measured in a measuring jug. Solids are measured on a scale to determine the correct mass. Recipe books nowadays indicate all the ingredients in measure of capacity because it is quicker to use measuring jugs and spoons than weighing each ingredient on a scale.

Learning Outcomes(LOs)

LO 1

TECHNOLOGICAL PROCESSES AND SKILLS

The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies

Assessment Standards(ASs)

We know this when the learner:

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies and compares their design aspects (e.g. who it is for, what it is for, what it looks like, what it is made of, how well it works, whether it will affect the environment);

1.3 performs, where appropriate, scientific investigations about concepts relevant to a problem, need or opportunity using science process skills;

1.4 writes or communicates a design brief for the development of a product related to a given problem, need or opportunity that clarifies the technological purposes of the solution;

1.5 suggests and records at least two alternative solutions to the problem, need or opportunity that link clearly to the design brief and to given specifications and constraints (e.g. people, purpose, safety, environmental impact, appearance);

1.7 develops plans that detail the making steps, including drawings and sketches that help to clarify the plans;

1.8 chooses and uses suitable tools to make products by measuring, marking out, cutting or separating, shaping or forming, joining or combining, and finishing the chosen materials;

1.9 works efficiently and safely;

1.10 evaluates the product according to the design brief and given specifications and constraints (e.g. people, purpose, environmental impact, safety, appearance), and suggests improvements and modifications if necessary;

1.11 evaluates the plan of action followed and suggests improvements and modifications if necessary;

1.12 draws appropriate sketches (e.g. labelled two-dimensional drawings of ideas, enhanced drawings of final solutions and drawings showing measurements) to communicate different information appropriately and effectively.

LO 2

TECHNOLOGICAL KNOWLEDGE AND UNDERSTANDING

The learner will be able to understand and apply relevant technological knowledge ethically and

We know this when the learner:

2.2 demonstrates knowledge and understanding of the reasons for the deterioration of different materials, and ways of preserving them (e.g. drying, coating, canning, sealing).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
