Fresh fish - how to recognise fresh produce
Freshness guaranteed: How to recognise high-quality fish and what you should look out for in different types of fish
Fish is not only delicious, but also healthy. It provides valuable omega-3 fatty acids, high-quality proteins and important minerals. However, one thing is crucial in order to really utilise the many benefits: the quality of the fish. The fresher the better. Spoiled fish not only has an unpleasant flavour, but can also cause serious health problems. In this blog post, we will tell you how to recognise that your fish is fresh and what you should look out for in different types of fish and seafood.
Why is it so important that the fish is fresh?
Freshness is regarded as the highest quality criterion for edible fish. However, this is not only because fresh fish tastes best, but also because it is a criterion for the risk-free consumption of fish. Fish meat consists of almost 90 per cent water and protein. Both form the perfect breeding ground for germs and bacteria and make raw fish spoil quickly. To avoid food poisoning from bad fish, you should therefore make sure it is fresh. This applies in particular to raw fish used for sushi or sashimi. Incorrect storage, a break in the cold chain and external injuries that occur during catching or processing can greatly reduce the quality of the fish.
How do you recognise fresh produce?
But you don't need to be afraid. With our practical tips, you can easily assess the freshness of your fish. In principle, there are three criteria:
- the external appearance,
- the consistency of the flesh
- and the odour. When buying fish, you often have to rely on the external characteristics. Eyes, scales, skin and gills provide you with clear indications of fresh fish quality.
Recognise freshness by external characteristics
Quality high-quality fish has clear, shiny eyes that protrude slightly. They look moist and alive, as if the fish has just been caught. However, if the eyes are milky or sunken, this means that the fish has been lying around for a while and is no longer fresh. The same applies to fish and seafood: Bright scales and shiny skin are always a good sign. The scales should lie smoothly against the body and not fall off easily. The skin appears moisturised and radiant. Dull or dry skin, on the other hand, indicates that the fish is no longer fresh. The fins should also be undamaged and clean and shiny. Broken, sticky or dry fins indicate inferior fish quality. The gills of the fish also say a lot about its freshness. Fresh gills are bright red to pink and have a slightly moist sheen. However, as soon as the gills are greyish or brownish in colour and have a slimy film or are dry, the fish is no longer fresh.
Odour as an indicator of freshness
One of the simplest, but also most effective signs of fish freshness is the smell. Fresh fish has a neutral, unobtrusive, slightly salty odour that reminds you of the sea breeze. However, as soon as a fish smells strongly ‘fishy’ or even sour and rotten, you should keep your hands off it. It is best to do the odour test on the whole fish at the gills and the abdominal cavity, where the stinky smell starts first.
Recognise the freshness of the fish by its flesh
Probably the most important criterion for assessing fish quality is the meat. The firmer and more elastic the meat, the fresher the product. You can check how fresh your product is with a simple test. Press lightly on the fish with your finger! If the fish is fresh, the flesh should immediately return to its original shape. However, if it is soft and a dent remains, the fish is no longer at its best. You can also rely on these criteria for fish fillets. They should be shiny and smell pleasant. However, if the meat looks dull and pale or even has yellowish discoloration, this is a sign of poor quality. The same applies if it is too wet or slimy.
What are the important criteria for different fish species?
Not all types of fish are equally sensitive when it comes to freshness. Some fish with a high fat content, such as salmon, tuna and giant grouper, spoil more quickly and should be checked particularly carefully. Here is a short list of different types of fish and their special features:
- Salmon should have firm, pink-colored flesh. Make sure that it does not look pale or dry.
- Tuna is characterized by its dark red, fleshy fillet. You should watch out for discoloration and dryness.
- Giant grouper of the highest quality can be recognized by its light and translucent flesh, which shimmers slightly pink. If you pay attention to these criteria, nothing will stand in the way of your healthy and tasty experience.
