Food Manufacture
Comparison of preserved peas
Different forms of food products are available to the consumer to suit different purposes. In your study of the core strand, Food manufacture, you are expected to investigate through experimentation, the suitablity of packaging materials for different food products (Board of Studies, 1999: 21). This experiment evaluates which packaged form best suits individual needs. Comparisons for colour, taste, texture and general quality are personal judgements which may influence consumers' decisions.
Outcomes
This material addresses aspects of the following syllabus outcome:
H1.1
The student explains manufacturing processes and technologies
used in the production of food products

Experiment
1. Evaluate the package
You will need:
fresh peas
canned peas
packet of dried peas
packet of frozen peas.
Rate the packages from1 to 4 (with 1 being the best) in a table taking into account visual appeal, clarity of instructions, and the information on the label.
| PRODUCT | PACKAGE RATING |
|---|---|
| Fresh peas | |
| Canned peas | |
| Dried peas | |
| Frozen peas |
2. Weight versus price
Using the same packets as in activity 1, calculate the cost per gram of peas.
| FORM | WEIGHT | PRICE | PRICE per GRAM |
|---|---|---|---|
| Fresh peas | |||
| Canned peas | |||
| Dried peas | |||
| Frozen peas |
3. Taste
- Prepare each form of peas, noting the time taken for preparation. Follow the instructions on the packet if they are given.
- Place each form of peas on a separate plate, labelling each plate separately.
- Evaluate each form for colour, flavour and texture.
Rate each factor from 1 to 5, five being for most desirable
characteristics
| FORM | COLOUR | FLAVOUR | TEXTURE |
|---|---|---|---|
| Fresh peas | |||
| Canned peas | |||
| Dried peas | |||
| Frozen peas |
4. Nutrition
Using food composition tables or software establish which peas are the most nutritious. Record your results in the table below.
| FORM | PROTEIN | SODIUM | CALCIUM | |
|
|---|---|---|---|---|---|
| Fresh peas | |||||
| Canned peas | |||||
| Dried peas | |||||
| Frozen peas |
5. Conclusion
- Which form of packaging appeared to offer the best product?
- Which form of peas has the longest storage life?
- Which form of peas was the most convenient to prepare?
- Which form of peas has the optimum nutritional value?
- Which form of peas offers most to you as a consumer?
- Consider each form of peas and suggest situations where each form of preservation is desirable, for example, dried peas are light to carry when bushwalking.
