The main requirement for any fish is the quality and absolute freshness of the product. Stale fish can cause serious illness. All methods of protecting a fish product from spoilage are ineffective, since they cannot "fix" a spoiled product. Moreover, these methods also cannot guarantee the freshness of the fish indefinitely.
Instructions
Step 1
Method 1 is the easiest
The smell of stale fish product is best determined by boiling a test piece in a sealed container. Also, the smell of spoiled fish can be detected like this: stick a knife heated in boiling water into the thickness of fish meat and bring it to your nose. If you want to check the quality of smoked or salted fish, then use a wooden hairpin, also pierce the fish, twist the hairpin several times in the thickness of the meat and bring it to the nose. A benign salted fish has a normal odor in all parts of the body. When buying fish in a barrel, pay attention to the brine, it should not have a perishable odor.
And yet, you should not trust only the sense of smell, you also need to examine the appearance of this product.
Step 2
Method 2 - Exact inspection
Pay attention to the skin and scales of the fish. Live fish should be well-nourished, healthy and agile. Such a fish has an open back, the gills should rise and fall evenly, the fish scales are intact and should not have any spots or damage. The fish should swim in the depths of the water, and not on its surface. Chilled fish should be subject to a more careful examination, since it spoils quickly, and if not properly stored, it quickly becomes unusable. The chilled fish has a dense body, put it on your hand, it should not bend under any circumstances. Take a closer look at the gills, they should be bright red. You can also throw fish into the water, fresh fish will quickly drown. Frozen fish should be free of stains and damage, the skin should fit snugly against the skin. Tap on it: if the fish makes a ringing sound, then this is a well-frozen product. Dried and dried fish should not have a musty smell and mold.
Step 3
Method 3 - The most obvious
Press your finger on the fish, the hole should quickly and completely recover. If the dent from the finger remains, then this means that this product is old and hardly fresh.
