Penaeid Shrimp Research Paper

Penaeid shrimps are valuable aquatics which their commercial utilization began in 1959 in the Iranian waters of the Persian Gulf. The majority of the catch composition (71%) is Penaeus semisulcatus, and the rest are 16% Metapenaeus affinis and 13% Parapenaeopsis stylifera (Paighambari, & Daliri, 2012). Parapenaeopsis stylifera or Kiddi shrimp (Gentek in Iran) is a kind of marine small shrimp, which does not exceed 145 mm. Gentek is distributed from Persian Gulf to Indian ocean and bay of Bengal. It is is typically found in the coastal waters of Kuwait, Iran, Pakistan, Sri Lanka and India and Bangladesh and it is one of the important species in Pakistan and the west coast of India and Bangladesh. (Hosseini, 2012). Gentek is rich in protein, minerals, and chitin but it has relatively low commercial value and receives less attention in the locall markets due to its size (Hosseini, 2012). Gentek is usually sun dried and mainly exported to Persian Gulf States (Shaviklo, 2012). However, various attempts have been

2011a,b). A continuous line for puffed corn snack processing (Tabriz Food Machinery, Tabriz, Iran) was used for the experiments. A ribbon blender was used for mixing corn grits with shrimp powder and water. The mixture was fed at a speed of 300 kg/h with a pressure 5.5±0.5 bar into a single screw extruder with a barrel temperature of 160±5˚C. The die was with 12, 4 mm wide holes. The screw was 8 cm wide and 23 cm long. The puffed extrudates were passed directly into a rotary dryer using hot air for reducing moisture to 2.5-3%. The extrudates were transferred continuously into a snack coater to be coated/seasoned with a mixture of vegetable oil, salt, cheddar cheese powder, whey powder and colorant at a temperature below 60˚C (Shaviklo et al. 2011a,b). The cold snacks were packed in oriented polypropylene (OPP) bags and stored at ambient temperature
