Nitrite Content of Some Foods in Malaysia
نویسنده
چکیده
Nitrat and nitrit adalah bahan tambah yang biasa digunakan dalam pengkiuran daging. Bahan-bahan ini juga memberi warna dan perisa yang baik dan dapat merencat penumbuhan mikroorganisma Clostridium botulinum. Nitrit boleh bertindak dengan amina sekunder dan membentuk sebatian nitrosamina. Nitrosamina inilah yang menjadi satu kontroversi berhubung dengan penggunaan nitrit kerana nitrosamine ini mempunyai kesan karsinogenik kepada manusia. Kajian analisis kandungan nitrit he atas beberapa jenis makanan telah dilakukan. Paras reja nitrit dalam hasil-hasil daging adalah dalam julat 14 — 53 bpj, dalam jeruk buah-buahan dan sayur-sayuran adalah 7-81 bpj dan pada ikan-ikan kering 11 38 bpj. Hasil kajian ini menunjukkan bahawa paras reja nitrit dalam kebanyakan makanan adalah kurang dari paras 200 bpj yang dibenarkan.
