In this brief guide, we will address the question, “does fish sauce go bad” as well as other questions pertaining to the subject at hand like how much time does fish sauce take to go bad or what are some of the storage practices needed to prolong the shelf life of fish sauce.
Does fish sauce go bad?
For the most part, no, fish sauce does not go bad. It goes bad rarely, mostly depending upon its preparation technique and storage conditions. It gradually loses its organoleptic properties such as colour, flavour and odour.
Items like fish sauce are used in small amounts while cooking; therefore, such questions are very common, and people often wonder if it goes bad or not. Well, you have your answer now.
As a matter of fact, fish sauce often lasts longer than its expiry date, simply because of the high sodium content. Sodium acts as a natural preservative that does not allow the growth of microorganisms.
Fish sauce will also retain its freshness and flavour after the expiry date for a good period of time before it starts to lose its efficacy and flavour. Keep in mind that it is still safe to consume. The only change you’re going to experience is a darker colour and stronger aroma due to the oxidation process.
How to tell if fish sauce is rotten or spoiled?
Being a fermented beverage, it is highly unlikely that fish sauce will spoil in a traditional sense. It can only go bad if proper hygiene and safety measures are not ensured.
The fish sauce contains a high amount of salt content which can be crystallized or settled on the bottom of the container if stored for a long period, but it does not mean that your fish sauce has spoiled.
Fish sauce is translucent liquid and does not contain any sediments when it is fresh. As time goes by, due to physicochemical changes, particles are formed and the liquid becomes cloudy due to protein precipitation
Fish sauce has a fresh amber, reddish-brown colour which might get darker by the age. Again, it won’t be harmful for consumption until you see microbial spoilage, mould growth and experience unpleasant or foul smell. In such a case, the fish sauce should be discarded.
The shelf life of the fish sauce
Fish sauce doesn’t last forever, its quality degrades over time. As it is one the condiments used rarely or in small quantities in food products. Moreover, only a limited number of recipes require fish sauce as an ingredient.
The shelf life of fish sauce depends upon its storage conditions. Fish sauce can last from 12 months to 24 months or even more, if stored at ideal storage conditions.
The shelf life of fish sauce can be prolonged if placed in a dark and dry area.
Packaging material or container in which it is placed also matters in prolonging the shelf life.
Not only fish sauce, anything can go bad if not stored appropriately. Unopened fish sauce bottles can last in good quality for even about 3- 4 years.
How to store the fish sauce
Fish sauce is a rich source of amino acids, minerals and vitamins. The fish sauce should be stored away from light, in a dark and dry area to avoid photolytic degradation.
Fish sauce has low or controlled water activity which means water is very well bound to salt and other molecules, lessens the possibilities of microbial spoilage. Therefore, fish sauce can be stored at room temperature.
Why Refrigerate fish sauce?
Like already mentioned, fish sauce contains a huge amount of sodium that naturally prevents it from going bad. However, once it is opened it is recommended to store it at refrigeration temperature after sealing it tightly. The purpose of this is to enhance its shelf life by preventing oxidative degradation of compounds.
Storing it in the refrigerator is an ideal storage condition when optimal results are desired.
After all that we have discussed, it is safe to say that fish sauce can go bad. I mean, any food item will go bad if you are not storing it properly. In the case of fish sauce, the chances are highly unlikely because there is no special method involved.
