Palm Kernel Testa Removal And Its Effects On Extracted Oil Quality

Isirong kelapa sawit disaluti oleh lapisan nipis perang kegelapan yang merupakan testa. Testa amat sukar untuk tersingkir kerana testa kuat melekat pada biji benih isirong. Kehadiran testa akan menjejaskan warna minyak. Maka, testa akan dibuang sebelum proses pengekstrakan bagi meningkatkan kualiti...
