Penternakan ikan haruan (Channa striata) dengan diet kaya dengan lipid
yang diperoleh daripada sumber ikan dan kacang soya dapat meningkatkan
kecekapan reproduksinya. 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. |
