Kajian Aktivitas Antioksidan Mi Basah Substitusi Tepung Umbi Kimpul dengan Penambahan Ekstrak Klorofil Batang Bayam dan Kangkung

Consuming noodles with health benefits is becoming a trend in the pandemic. Noodles with chlorophyll sourced from spinach and kale are thought to increase antioxidants. Utilization of chlorophyll extract of spinach and kale stems can reduce vegetable waste and substitution of kimpul flour can reduce the use of wheat flour. The purpose of this study was to analyze the effect of the addition of spinach and kale chlorophyll extract on the physicochemical properties of wet noodle products and the best results from the addition of chlorophyll extract in various concentrations from spinach and kale stems. The research consists of several stages. First, the manufacture of kimpul tuber flour, followed by the manufacture of chlorophyll extract of spinach and kale, then the manufacture of wet noodles, then physicochemical analysis and organoleptic tests (color, taste and preference). The method used is a simple randomized block design (RBD) experimental method with a ratio of the proportions of wheat flour (50%): kimpul tuber flour (40%): spinach chlorophyll extract: kale chlorophyll extract, which consists of 5 treatment combinations, namely BK1: 5% , BK2 : 10%, BK3 : 10%, BK4 : 7%, BK5 : 7% and repeated 2 times. The results showed that the addition of chlorophyll extract of spinach and kale had a significant effect on antioxidant activity and fat. However, it did not significantly affect the analysis of water content, ash, fat, carbohydrates and organoleptic taste, color and preference. The best treatment according to the de garmo test is the BK2 treatment with the addition of 10% spinach chlorophyll extract, with the results of water content 31.95%, ash 2.11%, protein 10.82%, fat 8.45%, carbohydrates 47.63% , antioxidant activity 73.73%, then organoleptic taste 5.04, color 5.6 and preference 5.56.
