PENGARUH PEREBUSAN SAYUR BAYAM MERAH (Amaranthacea gangeticus) TERHADAP KANDUNGAN NITRIT (NO₂⁻) DENGANBERBAGAI VARIASI WAKTU

Abstract

he red spinach is a complementary vegetable dish that has a characteristic feature that the stems and leaves of red. Chemical substances that can be found are protein, fat, carbohydrates, potassium, iron, amaranthin, routine and purin, and vitamin A, B and C. In general, people already know that spinach vegetable stew can heated, but many do notknow how much influence a change in the nitrite content of boiling red spinach with a variety of time. The purpose of this study was to analysis effect of boiling red spinach to the nitrite (NO₂⁻) content with variety of time for 0 hours, 3 hours, and 5 hours. The maximum limit allowed nitrite levels in accordance ADI (Total Daily Intake) established by WHO is 8 mg Nitrite per 60 kg body weight or equivalent to 0,133 mg Nitrite/kg body weight. Nitrite content in a vegetable stew ofred spinach was determined using quantitative methods that measuring the value of nitrite contentin the boiled red spinach with variety of time for 0 hours, 3 hours, and 5 hours with diazo method and using a spectrophotometer. From the results of the research it was obtained with variations in time 0 hours, 3 hours, and 5 hours were 5,14 mg/kg; 10,25 mg/kg; dan 13,05 mg/kg. During stroge 0 hours to 3 hours increased 100% and for 3 hours to 5 hours had 30%. Storage red spinach vegetable stewfor 5 hours was seaved for consumption for the people with its weight body 60 kg’s in the result of boiled vegetable red spinach according to total amount ±611,4 grams of the result according with maximum limit of Acceptable Daily Intake (ADI) established by WHO. By knowing the nitrite content in a vegetable stew of red spinach is expected to consumers to immediately process the red spinach after purchase and consume immediately after cooking and not for too long vegetable red spinach store in the refrigerator.
