PENGARUH SUBSTITUSI JUS JAHE (Zingiber officinale) PADA PEMBUATAN SIRUP TERONG BELANDA (Solanum betaceum Cav.) TERHADAP NILAI GIZI DAN SIFAT ORGANOLEPTIK

ABSTRACT The purpose of this study was to determine the effect of addition of ginger Extract on organoleptic value and nutritional content of Dutch eggplant syrup. This study used a Completely Randomized Design (CRD). The formulation of this study was the comparison of Dutch eggplant Extract and ginger Extract with 5 levels ie. S0 (100% of Dutch Eggplant Extract), S1 (95% of Dutch Eggplant Extract: 5% of Ginger Extract), S2 (90% of Dutch Eggplant Extract: 10 % of Ginger extract), S3 (85% of Dutch Eggplant Extract: Ginger Extract of 15%) and S4 (80% of Dutch Eggplant Extract: 20% of Ginger extract). The S4 treatment was the most preferred treatment for panelists with a score of preference for the color, aroma, flavor and viscosity ie. 4.40 (likes), 4.53 (very like), 4.20 (likes) and 4.43 (like), respectively. The contents of glucose, vitamin C and antioxidant activity of S4 samples were 67.28%, 0.11% and 45.20 µg/mL. The more addition of ginger extract, the higher the level of preference for panelists and antioxidant activity increased.

Penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Formulasi penelitian ini adalah perbandingan sari terong belanda dan sari jahe dengan 5 taraf, yaitu S0 (Sari Terong Belanda 100%), S1 (Sari Terong Belanda 95% : Sari Jahe 5%), S2(Sari Terong Belanda 90% : Sari Jahe 10%), S3 (Sari Terong Belanda85% : Sari Jahe 15%) dan S4 (Sari Terong Belanda 80% : Sari Jahe 20%). Perlakuan S4 merupakan perlakuan yang paling disukai panelis dengan skor penilaian kesukaan terhadap warna aroma rasa dan kekentalan berturut-turut sebesar 4,40 (suka), sebesar 4,53 (sangat suka), sebesar 4,20 (suka) dan 4,43 (suka). Kadar glukosa, vitamin C dan aktivitas antioksidan sampel S4 yaitu 67.28%, 0,11% dan 45.20 µg/mL. Semakin banyak penambahan sari jahe maka semakin meningkat tingkat kesukaan panelis dan aktivitas antioksidan semakin meningkat pula. Kata kunci: Sirup terong belanda, sari jahe,
