Our country, the Philippines, is
surrounded by fishing grounds. Fisherfolk
almost always enjoy abundant catch, but
because fresh fish spoil easily, they need
to be processed and preserved. Preserved
fish products serve as alternative to fresh
fish especially when there is scarcity of
Fish processing includes steps and
procedures to preserve and improve the
quality of fish products.
IDENTIFYING FRESHNESS OF FISH
1. The color of the skin is vivid,not opaque.
2. The scales are intact or adhere well.
3. Body is stiff and a little slimy.
4. Fish sinks if placed in water.
5. Flesh is firm and elastic.
6. Has seaweedy odor rather than fishy
7. Eyes are bright, gills are red.
Freezing is the simplest and the most natural way of
preserving fish. Freezing is very easy and safe to do,
The following are the simple steps to follow in freezing
1. Select fresh fish for freezing.
2. If the fish are small like dilis, wash and freeze right away.
If fish are large like bangus, remove scales, entrails, and
trim fins and tail and wash.
3. Wrap fish in plastic wrap or put in container packed tightly
to eliminate air.
4. Label wrapped fish or container with name and date.
5. Freeze immediately.
1. Smoking- is a slow way of broiling and
has very little preservative action.
Smoking adds a distinctive flavor. Here,
the fish is placed in close proximity to the
fire and the fished is cooked and saturated
with smoke. It is sometimes called
2. Drying or Dehydration Method- one of the more
popular techniques of preserving fish is drying or
dehydrating method. It is the removal of moisture in
food to them less perishable.
Drying or dehydration provides the following
a) Dried food requires less storage space than other
types of food.
b) Dried food weighs much less than the equivalent
amount of canned products.
c) Food can be preserved without the addition of
sugar or any other preserving agent.
DRYING OR DEHYDRATION OF FISH
a) Wash the fish thoroughly.
b) Open the belly cavity and the visceral organs.
c) Rinse the fish in running water. Drain.
d) Mix 10% brine solution (1 part salt to 9 parts water).
e) Soak the fish in a 10% brine solution of salt for 30 to 40
f) Drain the fish and wash thoroughly.
g) Place the salted fish in woven bamboo racks to dry under
the sun or solar dryer for 2 to 3 days.
h) Let cool, then place in clean boxes or baskets or wrap
them in wax paper.
i) Store in a cool place.
4. Fish canning- canning involves the even heating of
food in tin or glass containers and hermetically sealing
The following steps will contribute to the success
of this method:
a) Careful selection of the raw materials (the kind of
fish for preserving)
b) Check the equipment to be used
c) Quick preparation to conserve freshness
d) Provide a time table
e) Cans and jars should be truly hermetically sealed
f) Store in a cool place
Common methods used in canning are:
1. Open-Kettle Method— the sterilized or
heat-treated food is placed in sterile jars
and completely sealed without any
2. Can-Cooked Method— the prepared
food is packed in jars or cans. They are
either packed cold or thoroughly heated
to partially cooked the food before
