Abstract
Fruit wine adalah wine yang terbuat dari buah buahan selain anggur yang memiliki kandungan alkohol sekitar 9-14%. Pada umumnya fruit wine dibuat hanya menggunakan buah tanpa menggunakan bahan tambahan yang dapat meningkatkan kandungan antioksidan. Tujuan dari penelitian ini adalah menentukan rasio nanas dengan air dan konsentrasi daun mint yang tepat terhadap aktivitas antioksidan serta fisikokimia fruit wine. Penelitian dilakukan dalam dua tahap, dimana pada tahap pertama dilakukan analisis terhadap bahan awal, sedangkan pada tahap kedua dilakukan pembuatan fruit wine dengan tambahan konsentrasi daun mint dan analisis antioksidan dan fisikokimia. Faktor yang digunakan dalam penelitian ini adalah rasio nanas dan air serta konsentrasi daun mint. Rasio nanas dan air yang digunakan dalam penelitian ini adalah 1:2, 1:3 dan 1:4; dan konsentrasi daun mint yangdigunakan dalam penelitian ini adalah 4,76%, 9,09%, dan 13,04%. Hasil penelitian menunjukkan fruit wine dengan rasio nanas dan air 1:2 dan konsentrasi daun mint memberikan sebesar 13,04% merupakan fruit wine terbaik dari segi antioksidan dengan nilai antioksidan sebesar 5222,23±443,84 ppm, total fenolik sebesar 2156,06±7,14 mg GAE/L, total flavonoid sebesar 32,86±0,21 mg QE/L, kadar alkohol sebesar 13,62±0,09%, massa jenis sebesar 0,988±0 g/mL, tingkat keasaman (pH) sebesar 3,36±0,14, total asam tertitrasi sebesar 7,63±0,1%, total padatan terlarut sebesar 7,25±0,14°Brix, dan warna sebesar 87,74±0,02°Hue. Dapat disimpulkan bahwa kenaikan rasio nanas dan air serta konsentrasi daun mint dapat meningkatkan aktivitas antioksidan, total fenolik, total flavonoid, kadar alkohol, nilai pH, total asam tertitrasi, total padatan terlarut dan menurunkan massa jenis, kecerahan dan °Hue fruit wine. / Fruit wine is wine made from fruits other than grapes which has an alcohol content of about 9-14%. In general, fruit wine is made using only fruit without using additional ingredients that can increase the antioxidant content. The purpose of this study was to determine the ratio of pineapple to water and the appropriate concentration of mint leaves on the antioxidant and physicochemical activity of fruit wine. The research was conducted in two stages, where in the first stage the analysis of the starting materials was carried out, while in the second stage, fruit wine was made with the addition of mint leaf concentration and antioxidant and physicochemical analysis. The factors used in this study were the ratio of pineapple and water and the concentration of mint leaves. The ratio of pineapple and water used in this study was 1:2, 1:3 and 1:4; and the concentration of mint leaves used in this study were 4,76%, 9,09%, and 13,04%. The results showed that fruit wine with a 1:2 ratio of pineapple and water and a mint leaf concentration of 13,04% was the best fruit wine in terms of antioxidants with an antioxidant value of 5222.23±443,84 ppm, total phenolic content of 2156.06±7,14 mg GAE/L, total flavonoids of 32.86±0,21 mg QE/L, alcohol content of 13.62±0,09%, density of 0.988±0 g/mL, acidity (pH) of 3.36±0,14, total titrated acid of 7.63±0,1%, total dissolved solids of 7.25±0,14°Brix, and a color of 87.74±0,02°Hue. It can be concluded that increasing the ratio of pineapple and water and the concentration of mint leaves can increase antioxidant activity, total phenolics, total flavonoids, alcohol content, pH value, total titrated acid, total dissolved solids, and decrease density, brightness, and °Hue of fruit wine.
