APLIKASI SERBUK WORTEL SEBAGAI SUMBER β-KAROTEN ALAMI PADA PRODUK MI INSTAN

Abstract

ABSTRACT

The objective of this research was to study the use of carrot powder as a source of natural β-carotene in instant noodle. Four formulas were developed based on carrot powder level added into the formula (0%, 10%, 15%, and 20%). The carrot instant noodle was evaluated for sensory properties by 30 panelists. The best formula was analyzed for chemical properties, including proximate composition, dietary fibre, and β-carotene. The physical properties were analyzed in color, cooking time, elasticity, and water holding capacity. The experimental design applied terms of Complete Randomized Design. The result showed that instant noodle with 15% carrot powder was the best formula of carrot instant noodle. No significant difference in acceptance between this formula and commercial instant noodles. Product was composed of moisture content 7.75% (wb), ash 1.59% (d.b), protein 12.82% (d.b), fat 1.41% (d.b), carbohydrate 84.18% (d.b) and β-carotene 2 390 μg/100 g (199 RE or 99.5 RAE/serving size). Carrot instant noodle had physical properties as cooking time was 3.5 minutes, the color was yellow-redish, elasticity properties was 162.22%, and water holding capacity was 143.89%. This noodle contribute above 15% RDA of vitamin A for the children aged 4—5 years.

ABSTRAK

Tujuan penelitian ini adalah untuk mempelajari penggunaan serbuk wortel sebagai sumber beta karoten alami dalam mi instan. Empat formula dikembangkan berdasarkan jumlah serbuk wortel yang ditambahkan (0%, 10%, 15%, dan 20%). Mi instan wortel dievaluasi sifat organoleptiknya oleh 30 orang panelis. Formula terbaik dianalisis sifat-sifat kimianya meliputi komposisi, serat pangan, dan beta karoten, sedangkan sifat-sifat fisik yang dianalisis adalah warna, waktu masak, elastisitas, dan daya serap air. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap. Hasil penelitian menunjukkan bahwa mi instan dengan penambahan 15% serbuk wortel merupakan formula terbaik. Tidak ada perbedaan yang nyata dalam penerimaan antara mi instan formula ini dengan mi instan komersial. Produk mi instan ini mengandung air sebesar 7.75% (bb), abu 1.59% (bk), protein 12.82% (bk), lemak 1.41% (bk), karbohidrat 84.18% (bk) dan karoten 2 390 μg/100 g (199 RE atau 99.5 RAE/takaran saji). Mi instan wortel mempunyai sifat-sifat fisik seperti waktu masak 3.5 menit, warna kuning kemerahan, elastisitas 162.22%, dan daya serap air 143.89%. Mi ini berkontribusi sebesar 15% terhadap Angka Kecukupan Gizi vitamin A untuk anak usia 4—5 tahun.
