Permintaan pengguna ke atas makanan sentiasa berubah. Pada hari ini pengguna menuntut makanan yang segar dan asli. Pempasteuran terma bukan sahaja boleh membunuh mikroorganisma tetapi boleh memberi kesan kepada rasa, warna dan kualiti makanan yang digunakan. Kaedah pempasteuran sejuk dibangunkan untuk membunuh mikroorganisma tanpa penggunaan haba. Salah satu kaedah ialah dengan menggunakan medan denyut elektrik untuk pempasteuran makanan cecair. Kajian adalah melibatkan penggunaan medan denyut elektrik keatas makanan cecair seperti susu. Sampel susu dimasukkan ke dalam bekas rawatan dan dirawat menggunakan medan denyut elektrik. Maksimum voltan yang mampu dibekalkan ialah 17 kV. Parameter seperti kekuatan medan elektrik, bilangan denyut, lebar denyut diubah-ubah untuk mengkaji kesannya terhadap kadar ketidakaktifan mikroorganisma. _________________________________________________________________________________________ Consumers’ requirements for foods are contantly changing. Today they demand the foods that are fresh and natural. Thermal pasteurization not only kills contaminating microorganisms but also affects the taste, colour and nutritional quality of foods. Cold pasteurization methods have been developed to kill microorganisms without the application of heat. One such method is the use of pulsed electric fields (PEF) for pasteurization of liquid foods. This research is about the usage of pulsed electric fields (PEF) on liquid foodstuff such as milk. A sample of milk is placed into a treatment chamber and treated with pulsed electric fields. Maximum voltage supply for the treatment chamber is about 17 kV. Parameters used for this experiment such as strength of electric fields, the number of pulses and the width of pulses is changed periodically to investigate their effects on the inactivation of microorganisms.
