INFLUENCE OF TEMPERATURE AND MOISTURE ON THE PHYSICAL PROPERTIES OF FLOATING FISH FEED PRODUCED USING TWIN-SCREW EXTRUDER
Floating fish feed is widely used in aquaculture sector. These feed enables to observe fish each day, which helps in monitoring their health and also adjust the amount of feed per day and avoid wasted feed and pond pollution problems. There are many factors are affecting in floating fish feed production. In this experiment were conducted using three levels of Moisture (15%, 20% & 30%) and three levels of temperature (500C, 70 0C & 100 0C which were replicated three times. The remaining parameters are kept in standards.
Effect of Floating variables on Moisture and Temperature
The Experiment was started with the 15%,20% & 30%moisture added ingredients in a three replicates, the temperature was set at 500C in a texture chamber and the remaining parameters are kept in a constant. The same was carried out for 750C and 1000C.
Floating and Shape
There were, Nine experimental trails were conducted. In 15% moisture added experiment at varying level of temperatures shows that all feed are sinking and are having a mixed shapes. Due to low moisture levels there is no sufficient of water to softening and starch gelatinisation. Hence, the final output feed is sinking and shape is not good.
