Abstract

Omega-3 fatty acid has health benefits.  Indonesia has some species of fish that contain this kind of fatty acid such as lemuru.  However its utilization as -3 fatty acid source is still limited.  Fish oil from lemuru meal processing has poor quality because of its color and peroxide value, besides its free fatty acid content. Therefore purification process should be employed to improve its quality.This research was conducted to elucidate the performance of natural zeolite in purification of fish oil from lemuru meal processing. Acitivation of natural zeolite was employed to increase its adsorption capacity.  One  technique to activate natrural zeolite was chemical activation by strong acid (HF, H2SO4, dan HCl). Concentration level of activated zeolite in purification was also defined. The best result was natural zeolite activated by HCl and concentration level of 15%.  The characteristics of purified lemuru oil were as followed: absorbance at 430 nm of 0,24, free fatty acid content 4,12, ω-3 fatty acid content of 20,34%, and peroxide value of 93,6 meq/kg.Keywords: natural zeolite, purification, lemuru meal processing, fish oil

Abstract

Liberika coffee is one of the most popular types of coffee because of its distinctive taste, besides having advantages, Liberika coffee also has many disadvantages, namely the value of caffeine and high organic acids contained in liberika coffee, so that if excessive coffee consumption can have a negative impact on health. One alternative for coffee to be enjoyed by all people is to produce low-acid coffee with a fermentation method using yeast. However, if the duration of fermentation and the concentration of yeast are not appropriate will result in the formation of aliphatic acids which can result in fermentation defects and the taste of coffee decreases. The purpose of this study was to m endapatkan k onsentrasi yeast and fermentation time is rightto produce low-acid coffee powder from liberika coffee after going through the fermentation process. This study uses Factorial RAK pattern with two factors namely Yeast Concentration (1.5%; 2.5%; 3.5%) and Fermentation Duration (4 hours, 8 hours, 12 hours) each treatment was repeated 3 times. The data obtained was analyzed by ANOVA. Then a further test using BNT 5% is carried out and if the results are significantly different, it will be continued using 1% BNT. The results showed that the best yeast concentration and fermentation time were found in the treatment with 1.5% yeast concentration and 8 hours fermentation time which produced a total acid of 0.58% and water content of 5.49%. levels of caffeine, k adar ash, and kealkalian ash, with successive values 1, 1 %, 1.8% , and 61 1N NaOH. Kopi liberika adalah salah satu jenis kopi yang banyak digemari dikarenakan citarasanya yang khas, Selain memiliki kelebihan, kopi liberika juga memiliki banyak kekurangan yaitu nilai kafein dan asam organik yang tinggi terkandung dalam kopi liberika, sehingga apabila mengkonsumsi kopi dalam jumlah yang berlebih dapat berdampak negatif untuk kesehatan. Salah satu alternatif agar kopi dapat dinikmati oleh semua kalangan adalah dengan memproduksi kopi rendah asam dengan metode fermentasi menggunakan ragi. Namun jika lama fermentasi dan konsentrasi ragi tidak tepat akan mengakibatkan terbentuknya asam alifatik yang dapat mengakibatkan cacat fermentasi dan cita rasa kopi semakin menurun. Tujuan dari penelitian ini adalah untuk mendapatkan konsentrasi ragi dan lama fermentasi yang tepat untuk menghasilkan bubuk kopi rendah asam dari kopi liberika setelah melalui proses fermentasi. Penelitian ini menggunakan RAK pola Faktorial dengan dua faktor yaitu Konsentrasi Ragi (1,5%; 2,5%; 3,5%) dan Lama Fermentasi (4 jam, 8 jam, 12 jam) setiap perlakuan diulang sebanyak 3 kali.
