PENGARUH SUHU DAN LAMA PERENDAMAN TERHADAP KARAKTERISTIK INFUSED WATER KULIT JERUK NIPIS (Citrus aurantifolia)
Infused water or spa water is water that is added with pieces of fruit and left to stand for a few hours until the juice comes out, then ready to be consumed, thus providing flavor and health benefits. The lime peel of an orange contains more than 60% flavonoids and 170 different types of phytonutrients. Processing lime as an infused water drink can be an alternative to overcome acidity in citrus fruits. The purpose of this study was to determine the effect of duration and soaking temperature on the characteristics of lime peel infused water. This research was conducted from February to March 2024 at the Laboratory of Chemistry, Processing, and Sensory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This research method uses a Factorial Complete Randomized Design (CRD) with 2 treatment factors, namely the length of soaking time (A1 = 2 hours, A2 = 4 hours, A3 = 6 hours) and soaking temperature (room temperature and refrigator temperature). Each treatment was repeated 3 times. Parameters observed included antioxidant activity, pH, total titratable acid and vitamin C content. The results showed that both treatments, namely, soaking time and storage temperature, significantly influenced antioxidant activity, pH, total titratable acid and vitamin C content. The interaction of the two treatments significantly influenced vitamin C content. Treatment A3B1 (6 hours soaking time and room temperature storage) is the best treatment with characteristics of antioxidant activity 172,24 ppm, total acid titrated 1.38%, pH 2.92 and vitamin C content 4,22 mg/100 g.
