Abstract
The shelf life of sturgeon fish is very short due to its high protein, moisture, polyunsaturated fatty acids (PUFA) and low connective tissue, and if it is not stored in appropriate and cold conditions (refrigerator or freezer), it spoils quickly. One of the methods of long-term preservation of aquatic animals is drying them. In the past, when refrigeration systems for cooling and freezing fish were not yet common, drying and salting all types of fish of large and small sizes was very vital. Drying fish using new technologies is now practiced in all fish, especially in small fish, including Moto, Kilka, and sardines. These fish are easy to catch and dry due to their small size and high nutritional value. Small fish often live in shallow seas and are caught by fishermen in the fall and spring. Since about 80 % ww is made up of water, they will have a lot of water activity and will spoil very quickly. One way to prevent spoilage of aquatic animals is to dry them. In the southern regions of Iran, especially the cities of Bandar Lengeh, Jask, Qeshm, etc., the drying process is traditionally carried out under direct sunlight for approximately 7 to 10 days due to the hot weather. This article discusses the importance and benefits of drying fish and new drying methods, including microwave, high electric field or electro hydrodynamic, infrared, heat pump, and ultrasonic vacuum. Using a fluid bed dryer to produce biscuits using concentrated sturgeon protein, the biscuits produced with 7% FPC had the best quality characteristics.
