KARAKTERISTIK PROKSIMAT DAN AKTIVITAS ANTIOKSIDAN PRODUK MIE KERING YANG DISUBSTITUSI DENGAN TEPUNG BUAH TINJANG (Rhizophora mucronata)

Abstract

Tinjang fruit (Rhizopora mucronata) is a mangrove plant that has a relatively high carbohydrate content. More processing is needed so that it can be utilized into processed forms, one of which is flour. The use of tinjang fruit flour in this study was used as a substitute for wheat flour in a food product. One of them is dry noodles. The purpose of this study was to determine the effect of tinjang fruit flour substitution on the proximate characteristics and antioxidant activity of dry noodles. This study used a Completely Randomized Design (CRD) method with One Way ANOVA Test. The treatment in this study was the substitution of tinjang flour with a percentage of 0%, 10%, 15%, 20%. The results showed that there was a significant effect between treatments on the proximate characteristics and antioxidant activity of dry noodle products. Dry noodle products with 10%, 15%, and 20% tinjang fruit flour substitution have fulfilled the SNI with an average value of water content, namely 0.69-4.04%, ash content, namely 1.84-2.38% and protein content, namely 11.00-12.78 %. The results of the antioxidant activity value with the best IC50 were found in dry noodle products with 20% of the tinjang fruit flour substitution, namely 115,761 ppm.
