There are several factors that can contribute to the unbalanced saltiness of dried fish, some of which include:
1. Inadequate washing: If the fish is not washed thoroughly before drying, excess salt may remain on the surface of the fish, leading to a salty taste.
2. Inconsistent salting: If the fish is not salted evenly or the salt is not distributed properly, some parts of the fish may be saltier than others.
3. Improper drying: If the fish is not dried properly, the salt may not be evenly distributed or may concentrate in certain parts of the fish, leading to unbalanced saltiness.
4. Over-salting: If too much salt is used during the salting process, the fish may become excessively salty.
5. Type of salt used: Different types of salt have different saltiness levels, so the type of salt used for salting the fish can affect its overall saltiness.
To prevent unbalanced saltiness in dried fish, it is important to ensure that the fish is washed thoroughly, salted evenly, dried properly, and not over-salted.
