hipon suahe
50
The fish is not alive anymore but the head, tail, fins, and viscerals are still attached.
Whole or round
51
The fish has been eviscerated. Evisceration is making a slit down to the center of the soft belly, and then removing the entrails.
Drawn fish
52
The fish has been eviscerated, and scales, fins, head, and tail have been removed.
Dressed fish
53
This is a cross-section of fish obtained by cutting directly across the dressed fish at right angles to the length of fish.
Steak
54
Steak cut are about _ inch in thickness.
one-half to two-thirds inch
55
This is a whole or round fish with the scales intact, but a cut is made down to the backbone from just behind the head towards the tail, splitting the fish into two wings or flaps. A light weight of the palm is placed on top of the head of the fish to steady the fish before a knife is then turned flat and the cut is made.
Split fish
56
This is a process of removing the big and small bones of fish so that what is left is practically all flesh and skin. This process is gaining popularity especially among children who refuse to eat fish because it is quite cumbersome to remove the bones one by one as one eats it.
Deboned
57
One popular fish which is deboned in market? The process involves the use of a pair of tweezers or clinical forceps to remove all the intramuscular bones especially those near the tail.
bangus (milkfish)
58
The deboned bangus is available?
fresh, frozen, smoked, marinated, ready-to-cook
59
This is the fleshy part of the fish. It is removed from the backbone and ribs of the fish so that it is practically boneless. The skin of the fish may or may not be removed.
Fillet
60
These have two fillets that are joined together by the underside of the skin but once separated; each side becomes a single fillet.
Butterfly fillets
61
These are small and elongated chunks of the same size and thickness cut from the flesh portion of the fish.
Sticks
62
These are small and elongated chunks of the same size and thickness cut from the flesh portion of the fish.
Sticks
63
These are sticks that are cut further into small squares.
Cubes
64
Market Forms of Shellfish
1. Live
2. Whole
3. Shucked
4. Cooked
5. Cooked Meat

65
This includes crabs, clams, mussels, oysters, and snails. They are usually brought alive; and this is the sole indicator of their freshness.
Live
66
They have a rounded apron found in the middle of its underside.
Female crabs
67
They have a narrow and more pointed apron.
Male crabs
68
It is usually the female crab that contains more _ than the male crab.
aligi or crab fat
69
Shrimps of all kinds and sizes are normally bought whole but not alive, although suahe shrimp can stay alive for sometime.
Whole
70
These are the big shrimps that sometimes have their heads and thorax removed especially if they are to be transported abroad or in far places across the country. The heads are sold in the market, and are boiled and eaten as it is; or the heads are ground and their juice extracted, and is sauteed with meat in palabok sauce.
sugpo (prawns)
71
Oysters, clams, and scallops are sometimes sold in the market with their hard shells removed. Shucked oysters appear translucent if really fresh.
Shucked
72
Some shellfish like crabs, shrimps, and lobsters are marketed _ in their shells. Since shellfish do not stay fresh for long, it is better to have them cooked as they are keep fresh longer.
Cooked
73
Meat of crabs, shrimps, and lobster are removed from their shells and steamed. It is then packed in vapor-proof plastic packages and sold in the frozen section of supermarkets or in open market.
Cooked meat
74
Most shrimps that are unsold are removed from their segmented shells. Today, packaged shrimp meat is available in the frozen section of supermarkets.
Shelled
75
The meat is sometimes sprinkled with salt or washed in _ to keep it fresh.
brine solution
76
The process of cleaning the fish (Scaling).
* Hold the fish with one hand;
* Scrape the scales off with a knife almost vertical to the fish, from tail to head.
* Soak the fish before scaling to facilitate removal of scales.
* Use scrapers with serrated edges or made from numerous blunt nails driven through block of wood or softdrink bottle caps can be used instead of a knife.
77
The process of cutting the fish.
1. Remove the head (as in the case of large fish) by cutting above the collarbone behind the gills and then slicing straight through the backbone or snapping it off by bending it over the edge of the table.
2. Cut the pectoral fins together with the head.
3. Remove the dorsal fin by making vertical cuts down each side toward the backbone and then giving it a sharp pull (forward) toward the head.
4. Cut the ventral fin in a similar manner (as the dorsal fin).
5. Remove the pelvic fins by cutting the flesh that attach them to the belly flaps.
6. Remove tail with a chopping blow using a heavy knife.
78
Preparing Fish and Shellfish
* Cleaning the Fish
* Cutting
* Eviscerating
* Rinsing
* Slicing the Fish
79
The process of Eviscerating.
To eviscerate, make a slit down the center of the soft belly and with the use of your fingers in one hand, reach for the entrails inside, and with one scoop of the hand, pull out the entire entrails.
80
Wash the inside and outside of the fish thoroughly in clean, cool, running water. Allow to drain before cutting.
Rinsing
81
The process of Slicing the Fish.
Slice the fish according to customer preference. Some customers prefer a drawn fish or a dressed fish; others prefer deboned, steaks, fillets, stick, or split.
82
In preserving fish, the important principle to follow is?
to prevent or delay microbial decomposition or self-decomposition
83
You can apply the principle of preventing or delaying microbial decomposition or self-decomposition by using any method of?
preservation
84
Methods of Preservation (Preserving Fish)
* Chilling
* Refrigeration
* Freezing
* Salting
* Drying and Dehydration
* Smoke Curing
* Pickling and Spicing
* Fermentation
84
This includes the use of ice or mechanical refrigeration to 0°C. Those who catch fish from the sea, use ice to chill their newly caught fish.
Chilling
85
The temperature used with ice or mechanical refrigeration.
0°C
86
Within _ minutes after catching the fish, _ starts to set in.
40 minutes; rigor mortis
87
Within 40 minutes after catching the fish, this starts to set in. To delay the onset of this, the fish are chilled in ice even before they reach the market. Ice chills the fish quickly as it works well on the total surface of each fish. There should be sufficient quantity of ice for chilling the fish.
rigor mortis
88
A temporary method of preservation, but it is the cheapest and simplest way of preventing deterioration or spoilage.
Chilling
89
The more sophisticated way of keeping the fish fresh. Big fishing vessels make use of refrigeration especially in far areas of the ocean which takes time to reach the market or the factories, where canning of fish is done.
Refrigeration
90
Refrigeration temperature is from?
0°C to 5°C
91
The method ideal for storage for longer periods.
Freezing
92
Freezing temperature should be between?
-18°C to 0°F
93
Different types of freezing.
Sharp freezing and Quick freezing
94
Refers to freezing in air with natural circulation or with electric fans.
Sharp freezing
95
Sharp freezing's temperature is from?
-15°C to -29°C
96
Sharp freezing may take from?
3 to 72 hours
97
This is cooking the fish from a temperature of 0°C to -5°C in less than two hours.
Quick freezing
98
The fish is kept in the freezer until its temperature reaches _ or lower.
-20°C
99
Freezing fish in 2 hours or less is done as follows:
a. direct immersion in a refrigerant as is done when fish is immersed in a?
brine solution
100
Freezing fish in 2 hours or less is done as follows:
b. indirect contact with a refrigerant where fish or fish package is placed between two freezer plates in which refrigerant flows at _; or
-17.8°C to -45°C
101
Freezing fish in 2 hours or less is done as follows:
c. air blast freezing, where frigid air at _ is blown across the materials being frozen. This is in contrast to slow or sharp freezing.
-17.8°C to -45°C
102
Quick freezing has disadvantages over slow freezing, which are as follows:
a. There is less destruction of the fish flesh because of the small ice crystals formed around the fish.
b. The fish body solidifies fast, leaving little time for soluble materials to diffuse.
c. Enzymatic action in fish, which causes deterioration, is slowed down.
d. Bacteria do not have time to multiple when the fish is frozen quickly.
103
This preservation method uses salt (sodium chloride) as a preservation method. When the salt is applied on fish, it lowers the water content of the fish to the point where bacteria cannot live and grow when fish is covered with salt; water oozes out of the fish in a matter of time. The water passes out of the fish tissues, as salt penetrates into the tissues until it comes to a point that no more interchange of salt and water takes place.
Salting
104
As salting occurs, the liquid in the tissues becomes a concentrated salt solution. This is called?
osmosis
105
What is the preservation medium of salting?
salt (sodium chloride)
106
He explained the preservative actions of salt.
John Frazier (1978)
107
Salt ionizes and yields this which is harmful to the microorganisms.
chlorine
108
It reduces the solubility of oxygen in solution and deprives aerobic organisms of this needed oxygen.
Salt
109
It denatures oxygen protein of which microbial enzymes are composed, and, thus, interfere with their function.
Salt
110
The concentration of salt solution is measured in?
degree clinometer
111
It is allowed to float in a brine solution ranging from 0°C TO 35°C. The highest reading is at the weighted end of the clinometer spindle.
clinometer solution
112
It is based on the saturation of water with 25% sodium chloride at room temperature.
Maximum degree salinometer
113
The point where the saturation of water is 25% sodium chloride at room temperature is referred to as?
10° salinity
114
Plain water will read?
0° salinity
115
Saturation of fish with salt can be done through these methods.
Kench salting or dry salting and Brine salting
116
Split fish are salted, then arranged in layers in a jar or pot allowing the liquid to drain freely from the dish. After draining, resalting, and restocking may be required.
Kench salting or dry salting
117
This involves the immersion of cleaned fish on a brine solution. The fish are placed in a container with weight on top to keep fish completely immersed. The brine may be stirred once in a while, then more salt is added to keep salt concentration at about 25%.
Brine salting
118
The removal of water from the fish either by sun (as in sun drying) or wind (as in wind drying).
Drying
119
The removal of water from the fish through the use of artificially heated air, as in the use of oven or machines called mechanical driers.
Dehydration
120
Three factors that affect the rate of drying and dehydration.
temperature, humidity, movement of air
121
This makes evaporation of water from the fish surface faster.
Cold air
122
This refers to the presence of moisture in the air.
Humidity
123
The safe moisture content of fish is?
20%
124
Another method of dehydrating fish by removing water vapor from frozen fish under a vacuum.
Freeze drying
125
This preservation method involves four interrelated processes, namely: salting, drying, heat treatment, and smoking.
Smoke Curing
126
Fish immersed in brine solutoion.
Salting
127
Fish is dried either through artificial or natural means.
Drying
128
The fish is subjected at 29.40°C to 32.20°C with the smoking process done intermittently. This treatment is called cold smoking.
Hot treatment
129
When the fish is subjected to temperature of 49.80°C to 82.90°C, the duration of treatment is short. This is called?
hot smoking
130
Fish is subjected to smoke to impart the desired flavor and color of the fish.
Smoking
131
A method where fish is treated with vinegar condiment and spices to improve its flavor and lengthen its shelf life.
Pickling and Spicing
132
It is acetic acid, which prevents the growth of bacteria.
Vinegar
133
Spices commonly used include?
* pepper (ground or whole or partially whole)
* laurel or bay leaf
* cinnamon or kanela
* clover or clavas de comer
* oregano
* ginger
* garlic
* onion
134
The hydrolization of proteins in the tissues of fish. This process is facilitated by the presence of salt which helps in the microbial and enzymatic action in the fish.
Fish fermentation
135
Salt-fish proportion recommended is _ of the weight of fish.
2%
136
In fermentation, the fish is allowed to "ripen" which makes the flesh disintegrate. This is then allowed to age for _ or more which is considered the natural fermentation period.
8 months
137
The product of the fermentation is? A good one has a strong salty, cheesy taste, and is pasty in consistency. To protect its color, odor, and flavor, it can be stored in glass bottles or jars provided these are kept in a dark, cool room since light can affect its color. You can also use tin cans lined with plastic to protect its flavor. Tin cans alone will become rusty as the salt in this will react to the tin can by oxidizing it.
bagoong (fish paste)
138
Another fermented product of fish. It is a clear liquid on top of a fermenting mixture which appear after a few months. This pure _ is scooped out of the mixture and is a popular sauce for many Filipino dishes.
patis (fish sauce))
139
This has a yellow amber to brown color. The fermenting mixture that settled on the bottom is the bagoong. It is said that bagoong is the byproduct of patis.
pure patis
140
Two general methods of cooking fish and shellfish.
