Akurasi kandungan nutrisi dan keamanan rasio bahan secara langsung memengaruhi pertumbuhan dan perkembangan bayi serta kesehatan jangka panjang mereka. Sebagai unsur jejak esensial, seng dan besi memainkan peran vital dalam perkembangan sistem kekebalan tubuh dan fungsi hematopoietik. Oleh karena itu, kuantifikasi seng dan besi yang akurat dalam susu bubuk sangat penting untuk pengendalian mutu produk dan pengawasan keamanan pangan. Sesuai dengan Standar Keamanan Pangan Nasional GB 5009.14-2017 (Penentuan Seng dalam Makanan) dan GB 5009.90-2016 (Penentuan Besi dalam Makanan), penelitian ini menggunakan spektrofotometer serapan atom Zeeman A500. Dengan memanfaatkan kinerja koreksi latar belakang yang unggul dan stabilitas yang luar biasa, kami melakukan validasi metode untuk deteksi seng dan besi dalam susu bubuk.<\/p>\n<ol>\n<li>Kondisi Eksperimental<\/li>\n<\/ol>\n<p>Instrumen dan reagen<\/p>\n<p>Instrumen: Spektrofotometer Serapan Atom Nyala Zeeman A500, Digester Gelombang Mikro (dilengkapi dengan aksesori penghilang asam)<\/p>\n<p>Pereaksi: Asam nitrat<\/p>\n<p>Bahan Referensi Tersertifikasi:<\/p>\n<p>GBW(E)080130 Larutan Standar Unsur Tunggal Seng<\/p>\n<p>GBW(E)084937 Besi Elemen Tunggal Larutan Standar<\/p>\n<p>E701628 Bahan Referensi Tersertifikasi untuk Analisis Kuantitatif Besi, Tembaga, Seng, dan Mangan dalam Susu Formula Bayi Bubuk<\/p>","protected":false},"excerpt":{"rendered":"<p>Milk powder, especially infant formula milk powder, serves as a critical nutritional source in the early life stage.
