Analisa Perubahan Kandungan Nitrit ( NO2 - ) dalam Hasil Rebusan Sayur Bayam Hijau dengan Metode Spektrofotometri

Abstract

The research has been carried out on the changing of nitrite (NO2-) content in a vegetable stew of green spinach. Vegetable spinach were obtained from Kebun Baru Village farmers, Kecamatan Hamparan Perak, Kabupaten Deli Serdang. Content of nitrite were determined at vegetable spinach and the water of boiled vegetable spinach using spectrophotometric methods. From the results of the research it was obtained with variations in time 0, 1, 2, 3, 4, and 5 hours were 4,159; 5,319; 7,239; 8,719; 10, 149 dan 11,559 mg/kg. Value content of nitrites content of the the water boiled spinach were 1,729; 3,349; 3,889; 4,969; 6,129 dan 7,079 mg/kg. Respectively in order to obtain the total value of the content at boiled vegetable spinach there for of were 5,888; 8,668; 11,128; 13,688; 16,278 dan 18,638 mg/kg. Storaging of result of boiled vegetable spinach during 5 hours was seaved for consumtion for the people with its weight body 60 kgs in the result of boiled spinach vegetable according to total amount 428,16 grams of the result according with maximum limit of Acceptable Daily Intake (ADI).

Penelitian tentang perubahan kandungan nitrit (NO2 - ) dalam hasil rebusan sayur bayam hijau telah dilakukan. Sayur bayam diperoleh dari kebun sayur petani Desa Kebun Baru, Kecamatan Hamparan Perak, Kabupaten Deli Serdang. Kandungan nitrit ditentukan pada rebusan sayur bayam dan air rebusan sayur bayam dengan metode spektrofotometri. Dari hasil penelitian diperoleh nilai kandungan pada rebusan sayur bayam dengan variasi waktu 0, 1, 2, 3, 4, dan 5 jam masing-masing adalah 4,159; 5,319; 7,239; 8,719; 10,149 dan 11,559 mg/kg. Nilai kandungan nitrit pada air rebusan sayur bayam masing-masing 1,729; 3,349; 3,889; 4,969; 6,129 dan 7,079 mg/kg. Sehingga diperoleh nilai total kandungan nitrit pada rebusan sayur bayam dan air rebusan sayur bayam adalah 5,888; 8,668; 11,128; 13,688; 16,278 dan 18,638 mg/kg. Penyimpanan hasil rebusan sayur bayam hijau selama 5 jam aman dikonsumsi untuk seseorang yang berat badannya 60 kg sebanyak ± 428,16 gr hasil rebusan sayur bayam sesuai ketentuan ADI (Acceptable Daily Intake)/Jumlah Asupan Harian menurut WHO (Word Healthy Organisation).
