Determination of flavonoids in Citrus grandis (Pomelo) peels and their inhibition activity on lipid peroxidation in fish tissue
Zarina, Zakaria, Dr.; S., Y. Tan (Faculty of Food Science & Technology, UPM., 2013)The peels of pomelo contribute 30% of the fruit weight and yet it has been dump without recognizing the possible nutritional value of the peels. Study has been carried out to identify flavonoid content of the peels and ... -
Effect of buffer and pH on the protein extraction for chicken meat
M. K., Nahar; Zarina, Zakaria, Dr.; Uda, Hashim, Prof. Dr. (Trans Tech Publications, 2013)The study was undertaken to determine the extraction of proteins from chicken meat. The effect of buffer (phosphate, citrate and glycine) and four pH values (6.0, 7.0, 8.0 and 9.0) were investigated. The protein extractability ... -

Optimization of protein content in earthworm-based fish feed formulation for catfish (Clarius gariepinus)
Zarina, Zakaria, Dr.; Noor Hasyierah, Mohd Salleh; Alina Rahayu, Mohamed; Ahmad Anas, Nagoor Gunny; Siti Nur Amirah, Idris (Penerbit Universiti Kebangsaan Malaysia (UKM)Fakulti Sains dan Teknologi, 2012-09)The optimization of protein content in earthworm-based fish feed formulation was investigated in the study. Full factorial design (FFD) and central composite design (CCD) were used as a statistical tool to screen the range ... -
Protein solubility behaviour of fresh and frozen chicken meat in slaughtering and non slaughtering condition
Nahar, M. K.; Zarina, Zakaria, Dr.; Uda, Hashim, Prof. Dr. (Faculty of Food Science & Technology, Universiti Putra Malaysia, 2014)This work was investigated the protein solubility properties of meat from chicken in different body part. The effects of fresh and freezing condition were studied on the protein solubility as a functional property of ... -
Steaming process optimization, physical testing and analysis of growth performance parameters in earthworm-based pellets for African Catfish (Clarias Gariepinus)
Zarina, Zakaria, Dr.; Kulaab, Liam; Ibni Hajar, Rukunudin, Prof. Ir. Dr. (Asian Economic and Social Society, 2013-06)New formulation of fish pellets was designed by using earthworm powder and other economical ingredients such as fish meal, soybean waste and rice bran which were calculated using Pearson’s square method. The optimization ...
