This question was well attempted by the candidates. Most of the candidates were able to identify specimens L(Smoked fish) and M(Canned fish) as required in 3(a).However, in 3(b)(i-ii), most of them could neither give the similarities between specimens L (Smoked fish) and M (Canned fish) nor state the differences in the production methods of specimens L (Smoked fish) and M (Canned fish).
However in 3(c), majority of the candidates were able to describe the steps involved in the production of specimen L (Smoked fish). Most of the candidates were also able to list the materials that could be used in the production of specimen M (Canned fish) as required in 3d.
The expected answers include:
3(b)(i) Similarities between Specimens L (Smoked fish) and M (Canned fish)
- They are both processed fish products
- They are fishes in preserved forms
- They are fishes in edible forms
- Value has been added
(ii) Differences in the production methods of Specimens L (Smoked fish)
and M (Canned fish)
L (Smoked fish) M (Canned fish)
- Produced through application f heat Involves steaming and water extraction
Heat/smoke/smoking
- Makes use of smoking kiln Industrial processing involves complex
machinery
- Charcoal or firewood are the main Involves the use of electricity
source of heat energy
- Fish form partially changed Fish form completely changed
- Variable packaging materials/may Sealed in a can/well packaged
or may not be packaged |
