Objektif kajian ini adalah untuk menyedia dan menilai serbuk protein yang disediakan daripada haruan yang diternak dengan diet lipid khas (SFPP). Untuk mencapai objektif ini, langkah-langkah penyediaan SFPP perlu disediakan. Justeru itu, kajian ini dibahagi kepada dua bahagian. Dalam kajian fasa I, hanya ikan haruan komersial digunakan kerana sumber ikan yang diternak dengan diet lipid khas adalah terhad. Tujuan utama kajian awal adalah untuk menentukan cara penyediaan dua jenis produk iaitu serbuk filet haruan (WFP) dan serbuk protein haruan (HPP). Akibat penggunakan rawatan pembekuan ke atas hasil pengutipan fillet juga dikaji, iaitu pembekuan terus, pembekuan dengan air dan tanpa pembekuan. Untuk menyediakan WFP, langkah-langkah penyediaan yang terlibat adalah rawatan pembekuan, diikuti oleh penyediaan cincang filet dan pengeringan ketuhar untuk penyediaan WFP. Untuk penyediaan HPP, filet yang dicincang dipanaskan dengan air pada suhu 85 ºC. Specially-fed Snakeheads (Channa striata) are snakehead fishes fed with diets high in lipids sourced from fish and soybean which have been shown to improve their reproduction efficiency. The objective of this study was to prepare specially-fed protein powder (SFPP) from these snakehead fish and evaluate it. To achieve this objective, a method has to be developed for the preparation of such powders. Therefore, this study was divided into two phases. As the supply of specially-fed Snakeheads was scarce, only commercial snakehead was utilised during phase I to develop preparation methods for whole fillet powder (WFP) and snakehead protein powder (HPP). Effects of freezing treatments (direct freezing, freezing with water or no freezing) before filleting on fillet harvesting yield were also investigated. To prepare WFP, after freezing treatments, fish were filleted, minced and oven dried. However, to prepare HPP, minced fillet were heated with water at 85 ºC and the liquid extract was centrifuged to separate fat from protein. 2016-03 Thesis http://eprints.usm.my/31592/ http://eprints.usm.my/31592/1/TAN_BEE_HOOI_24.pdf application/pdf en public masters Universiti Sains Malaysia Pusat Pengajian Teknologi Industrial (School of Industrial Technology)
