How to preserve sweet and sour fish sauce to keep it for a long time?

Doctor CKI Dinh Tran Ngoc Mai , Department of Nutrition - Dietetics, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, replied: Fish sauce has long been an indispensable spice in Vietnamese family meals, helping to make dishes more delicious and flavorful.

Ready-mixed fish sauce should be stored in the refrigerator in a glass bottle or container.

Pure fish sauce can be used for a long time, about 1-2 years without using preservatives. The reason is because this type of fish sauce has a high salt content, which helps preserve the fish sauce completely naturally and helps them extend their shelf life.

Ready-mixed sweet and sour fish sauce is also often present in the meals of every Vietnamese family. This type of fish sauce is usually mixed from ingredients such as fish sauce, water, lemon juice, garlic, chili, sugar (depending on the type),... Therefore, the shelf life is short, only about 1 month if carefully stored in the refrigerator.

Pre-mixed fish sauce should be stored in the refrigerator in a glass bottle or container. Because pre-mixed fish sauce can easily ferment and spoil due to the addition of lemon, garlic, chili, etc., it is best to mix just enough fish sauce for each use, to avoid waste and ensure health.
