Food processing and utensils

Food Processing

ACTIVITY 1:

To be able to describe the term processing in terms of the technological process.

Introduction

The term processing covers a wide area. It has to do with the processing of materials and/or products into another final form or product. It entails the processing of anything, e.g. the processing of wheat into flour and then into bread, the processing of wood into furniture and the processing of material into clothing. In this module we will focus on food. In grade 9 we will focus on resistant materials (wood, metal, plastic and paper).

You will have the opportunity to plan and construct a food stall for the coming World Fair. The stall must represent a specific country and produce and sell the fast foods of that country. Before you can start, it is important that you obtain more information about kitchen utensils, safety, hygiene, first aid, measurement and the various food groups.

1.1 Define the term processing .

1.2 Give two examples of processing done in your town/area and give a brief description of each.

1.3 Use one of the examples in 1.2 and now describe the term processing in terms of the technological process. Use the terms design, make . . . . .

LO 1.5 LO 2.2

ACTIVITY 2:

To be able to describe the utensils generally used in food processing, as well as the function of each.

  • During the processing of food you will require a variety of utensils. It is important for you to know what these are and how to use them with confidence for the right purpose.
  • Utensils can be divided into five main groups according to the function they perform. These main groups are:
  • Measuring utensils
  • Mixing utensils
  • Cooking utensils
  • Baking and frying utensils
  • VariousWrite down the name of the utensils which belong to each of the following five groups. Also write down the function of each utensil.
  • Group: MEASURING UTENSILS
  • Group: MIXING UTENSILS
  • Group: COOKING UTENSILS
  • Group: BAKING AND FRYING UTENSILS
  • Group: VARIOUS

Assessment

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 technology.
This is demonstrated when the learner:
investigates:1.1 investigates the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a nationally relevant context;
1.3 develops and performs practical tests in the technological areas (Structures, Processing, and Systems and Control);
1.4 uses appropriate technologies and methods to:
  • collect relevant data from different sources and resources;
  • extract relevant data;
  • make meaningful summaries;use information to justify and support decisions and ideas;
designs:1.5 writes or communicates a short and clear statement or a design brief in response to a given identified situation for the development of a product or system;
1.6 lists product and design specifications and constraints for a solution to an identified or given problem, need or opportunity based on most of the design key words listed below:
    • people: age target market;
  • purpose: function;
  • appearance: colour, shape;
  • environment: where will product be used;
  • safety: for users;
  • cost: cost of materials;
1.7 generates several alternative solutions and writes notes, ideas that show some links to the design brief and specifications;
makes:1.9 develops a plan for making that outlines all of the following:
  • resources needed;
  • sketches showing the necessary dimensions or quantities;
  • all steps necessary to making the product;
1.10 chooses and uses appropriate tools and materials to make products by measuring, marking, cutting or separating, shaping or forming, joining or combining, and finishing different materials accurately using appropriate techniques;
1.12 uses safe working practices and shows awareness of efficient ways of using materials and tools;
evaluates: 1.13 tests and evaluates the products or systems with objectivity, based on objective criteria linked to the design brief, specifications and constraints, and suggests sensible improvements or modifications;
communicates: 1.15 presents ideas using two-dimensional or three dimensional sketches, circuit diagrams or systems diagrams that include all of the following features:
  • use of SA drawing conventions (e.g. dimension lines, labelling, line types, symbols);
  • notes to clarify and communicate design features and reasoning; enhancement of significant sketches like final solution drawings.
LO 2
TECHNOLOGICAL KNOWLEDGE AND UNDERSTANDING The learner will be able to understand and apply relevant technological knowledge ethically and responsibly.
This is demonstrated when the learner:
structures:2.1 demonstrate knowledge and understanding of frame structures:
  • the use and application of basic structural components (columns, beams, arches, buttresses, struts, stays, guys, ties);
  • reinforcing techniques for frame structures (triangulation, webs and fillets, orientation and cross-sectional area and members);
  • how frame structures can be made strong (e.g. relationship between the size and the shape of the base, the centre of gravity and stability;
processing:2.2 demonstrates a knowledge and understanding of how materials can be processed to change or improve their properties by adapting them to suit particular purposes:
  • to withstand forces (tension, compression, bending, torsion, shear);
  • to increase strengths or life-span;
  • how specific properties suitable for packaging can be achieved.

Memorandum

ACTIVITY 1

Introduction:

  • The module deals with food processing. Seeing that only a few schools have the necessary facilities to cook food, a fast-food dish has been chosen as learners can prepare it at home and put it together in the classroom. It would be very helpful if a microwave oven were available during the production process. Learners must be encouraged to develop sound business principles during the course of this module. It is for this reason that entrepreneurship is emphasized. The module could also be linked to possible market days.

1.1 Processing can involve any material or product that undergoes a process in order to form a new product. That entails the processing, combining, colouring, packaging, etc. of materials and products.

1.2 Any example that is distinctive of your environment, e.g. grapes to wine, wheat to bread, etc. can be used.

ACTIVITY 2

  • Use the pictures for this activity. The pictures have been jumbled and must be organized in the tables that follow them, as indicated in this memorandum.
  • The function of each piece of equipment must also be written down.

20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm

is it a question of log

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
