Abstract
INDONESIA:
Buah tomat (Lycopersicon esculentum Mill.) termasuk komoditi yang sangat besar di Indonesia. Namun karena tingginya kandungan air pada tomat mengakibatkan meningkatnya laju respirasi dan transpirasi yang akhirnya buah akan menjadi layu dan berakhir busuk. Buah tomat setelah matang sempurna akan cepat menjadi rusak/busuk yakni setelah 3–4 hari penyimpanan pada suhu kamar. Penelitian ini bertujuan untuk mengetahui pengaruh suhu penyimpanan terhadap kualitas buah tomat (L. esculentum Mill.), untuk mengetahui pengaruh perbedaan konsentrasi pati talas (Colocasia esculenta) pada aplikasi edible coating terhadap kualitas buah tomat (L. esculentum Mill.), dan untuk mengetahui pengaruh interaksi suhu penyimpanan dan perbedaan konsentrasi pati talas (C. esculenta) pada aplikasi edible coating terhadap kulaitas buah tomat (L. esculentum Mill.). Metode yang digunakan untuk memperpanjang umur simpan tomat yaitu edible coating dengan bahan pati talas. Penelitian ini dilakukan dengan RAL faktorial 2 faktor, faktor pertama yaitu perbedaan konsentrasi pati talas dan faktor kedua yaitu suhu penyimpanan. Parameter yang diukur yaitu susut bobot, warna, tekstur, vitamin C, dan kadar air. Hasil penelitian menunjukkan bahwa penyimpanan suhu dingin (±8-10ºC) pada buah tomat (L. esculentum Mill.) dapat mempertahankan kadar vitamin C dan kadar air. Buah tomat (L. esculentum Mill.) yang dilapisi edible coating pati talas (C. esculenta) dengan konsentrasi 5% dapat menurunkan susut bobot serta mempertahankan kadar vitamin C dan kadar air. Terdapat pengaruh interaksi suhu dingin (±8-10ºC) dan konsentrasi 5% pati talas (C. esculenta) pada aplikasi edible coating dalam mempertahankan kualitas buah tomat yaitu terhadap susut bobot, kadar vitamin C dan kadar air pada buah tomat (L. esculentum Mill.).
ENGLISH:
Tomato fruit (Lycopersicon esculentum Mill.) is a very large commodity in Indonesia. But because of the high water content in tomatoes resulting in increased respiration and transpiration, the fruit will eventually wither and end rot. Tomatoes after being ripe perfectly will quickly become damaged after 3–4 days of storage at room temperature. This study aims to determine the effect of storage temperature on the quality of tomatoes, to determine the effect of different concentrations of taro starch on edible coating applications on the quality of tomatoes, and to determine the effect of the interaction of storage temperature and the difference in concentration of taro starch on the application of edible coating to the quality of tomatoes. The method used to extend the shelf life of tomatoes is edible coating with taro starch ingredients. This study was conducted with factorial RAL 2 factors, the first factor was the difference in taro starch concentration and the second factor was storage temperature. The parameters measured were weight loss, color, texture, vitamin C, and water content. The results showed that cold storage (±8-10ºC) in tomatoes can maintain vitamin C levels and moisture content. Tomatoes coated with taro starch edible coating with concentration of 5% can reduce weight loss and maintain vitamin C levels and moisture content. There is an interaction effect of cold temperature (±8-10ºC) and a concentration of 5% taro starch on edible coating applications in maintaining the quality of tomatoes, namely weight loss, vitamin C levels and water content in tomatoes.
