| Summary: | This paper is consist the study of freeze dried tiger prawn (Penaeus Monodon) under vacuum condition at pressure 6.5 atm and temperature -40oC with a different size of tiger prawns (Penaeus Monodon). The drying process had been carried out for several days and it’s depending on the size of tiger prawns. Weight of tiger prawn is taken every six hour to monitor the drying process. The drying process proceeds until it reached constant weight. The quality of freeze dried tiger prawn was compared base on different size during the drying process. For each size, calculation is made based on percentage weight loss and the rehydration potential. Sample A (3 cm) had a highest percentage weight loss and rehydration capability with a less of rehydration time compare to sample B (6cm) and sample C (12 cm). The small structure size of tiger prawns (Penaeus Monodon) can reduce the time of drying in freeze dryer. Freeze dried tiger prawns (Penaeus Monodon) could be stored without refrigeration or at room temperature. This will reduce the weight of packaging for product delivery and thus can reduce the cost. The taste of the freeze dried tiger prawn is also being judge with sensory evaluation. The sensory evaluation had been carried out by 12 respondents. The sensory evaluation had been carried out based on the appearance, aroma, texture, taste, and mouthfeel. From the evaluation, most of the respondents can accept the taste of freeze dried tiger prawn. -Author- |
