Pramadika, Raditya Putra (2015) Dekafeinasi Kopi Robusta (Cofeea Canephora L.) Dengan Enzim Bromelin Kasar Dari Ekstrak Buah Nanas (Ananas Comosus Var Comosus) (Kajian Konsentrasi Enzim Dan Lama Proses Enzimatis). Sarjana thesis, Universitas Brawijaya.
Abstract
Kopi (Coffea spp) adalah spesies tanaman berbentuk pohon dan termasuk dalam famili Rubiaceae dan genus Coffea. Tanaman kopi terdiri dari jenis Coffea arabica, Coffea robusta dan Coffea liberica. Tanaman kopi mempunyai nilai komoditas eksport dan nilai ekonomis yang tinggi di pasar dunia, disamping merupakan komoditas yang kompetitif yang berkembang di Indonesia. Kopi memiliki manfaat dalam mencegah rasa kantuk, menaikkan daya tangkap panca indera, mempercepat daya pikir dan mengurangi rasa lelah. Akan tetapi kandungan kafein dalam kopi memiliki dampak negatif yaitu dapat meningkatkan konsentrasi plasma homosistein yang akan meningkatkan resiko penyakit kardiovaskuler jika meminum kopi dalam jumlah yang berlebih. Penelitian dilakukan dengan dua faktor, faktor pertama adalah tingkat konsentrasi enzim bromelin 10%, 15% dan 20% sedangkan faktor kedua adalah lama proses enzimatis (fermentasi) 24 jam, 36 jam dan 48 jam yang masingmasing diuji terhadap parameter kadar kafein, protein dan lemak. Dari hasil penelitian, perlakuan terbaik didapatkan pada konsentrasi enzim 10% dan lama proses enzimatis (fermentasi) 24 jam dilihat dari segi efisien. Karena hasil ANOVA dan uji BNT menyatakan tidak berbeda nyata. Selain itu dari perlakuan yang ada, didapatkan kadar protein terendah sebesar 3.64% pada perlakuan konsentrasi enzim 20% dan lama proses enzimatis (fermentasi) 36 jam. Pada kadar lemak terendah, didapatkan pada perlakuan tingkat konsentrasi 20% dengan lama proses enzimatis (fermentasi) 48 Jam. Serta kadar kafein terendah terdapat pada perlakuan dengan tingkat konsentrasi enzim 20% dan lama proses enzimatis (fermentasi) 48 jam. Dari hasil uji organoleptik, para panelis belum bisa menerima kopi enzimatis dari parameter rasa dan aroma sedangkan parameter kekentalan setara dengan kopi biasa.
English Abstract
Coffee was the plant species that looked like a tree and included Rubiaceae family and Coffea genus. Coffee plant consisted from Coffee Arabica, Coffea robusta, and Coffea liberica species. Coffee plant had high export commodity and high economically value in the world market, beside one of competitive commodity that developed in Indonesia. Coffee had benefit in preventing drowsiness, raise the sensitivity of senses, accelerate the power of mind, and decreased drowsiness. But caffeine in coffee had negative impact which could raise homosystein plasma concentration that could raise the risk of cardiovascular disease if someone drank in excessive amount of coffee. This research was done with two factors, the first factor was the level of bromelain enzyme concentration at 10%, 15% and 20% while the second factor was the time of enzymatic process (fermentation) at 24 hours, 36 hours and 48 hours which respectively was tested to caffeine, protein and fat levels parameters. The results showed, the best treatment could got from the research was enzyme concentration level 10% and time of enzymatic process for 24 hours that looked from efficiency point. Because ANOVA and BNT test declared that the factors were not actually different. Beside that, from the treatment there was the result from the lowest protein levels were 3.64% in the treatment from enzyme concentration levels 20% and the time of enzymatic process (fermentation) for 36 hours. In the lowest fat levels, there was got 9.67% in the treatment from enzyme concentration levels 20% with the time of enzymatic process (fermentation) 48 hours. Whereas the lowest caffeine levels which in the enzyme concentration levels 20% and the time of enzymatic process (fermentation) 48 hours. From organoleptic test, the panellist could not accept enzymatic coffee from taste and flavour parameter. Whereas from consistency parameter was equal to plain coffee.
