Abstract

Omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are essential fatty acids with numerous health benefits. The main sources of these fatty acids are fish and fish oils. However, fish supply is limited and the availability is uncertain. There are two main problems with regard to fish supply: overfishing and mercury contamination. In addition, food enrichment with fish oil is apparently challenging due to sensitivity of fish oil to oxidation, and fishy smell which make them less attractive to consumers. Based on above problems, alternative sources of EPA and DHA must be found. Analternative for omega-3 fatty acids are microalgae. This research aims to isolate, identify, and find microalgae biodiversity that are able to produce omega-3 fatty acids in their cells. Microalgae were isolated from fallen, senescent leaves of mangrove tree (Kandelia candel) in two locations in Aceh. The colonies were identified morphologically using light and stereo microscopes with 1000x magnifications. The results were compared with those in literatures. This research has isolated and identified some genus of microalgae thatwere predicted belong to order Labyrinthulida and family Thraustochytriidae. Morphological observations have also confirm identification of one fungi, genus Mortierella. All identified microalgae and fungi are omega-3 fatty acids producers, mainly EPA and DHA

Abstract

Indonesia termasuk negara pengkonsumsi mi terbesar di dunia. Selma ini, mi diproduksi dari tepung gandum. Namun untuk mengurangi ketergantungan terhadap impor gandum, perlu dicari alternatif lain sebagai bahan baku mi. Penggunaan tepung jagung dalam pembuatan mi dapat dijadikan sebagai alternatif serta kandungan betakarotennya juga bermanfaat bagi bagi kesehatan. Tidak seperti gandum yang mengandung gluten sehingga adonan mudah dibentuk, pembuatan mi jagung pelu ditambahkan zat tambahan yang dapat menggantikan sifat gluten. Penelitian ini bertujuan untuk mempelajari hidrokoloid yang dapat digunakan untuk memperbaiki karakteristik mi jagung. Mi yang dihasilkan selanjutnya dianalisis kadar air, kadar abu, cooking loss,uji putus, uji hedonik. Dari hasil analisis ini didapatkan sampel terbaik yang dilanjutkan analisis kadar serat kasar, kadar protein dan kadar betakaroten. Sampel terbaik yang didapatkan dari hasil penelitian ini adalah perlakuan xanthan gum 2% dengan hasil uji putus 2.50 cm, kadar air 40.19%, kadar abu 1.05%, cooking loss 2.21%, kadar protein sebesar 3.98%, kadar serat kasar 4.16% , kadar betakaroten 12.71 mg/L dan hasil dari uji hedonic mi jagung yaitu warna 3.36 (netral), aroma 3.24 (netral), rasa 3.00 (netral) dan tekstur 2.73  (netral).Abstract: Indonesia belongs to the country with the highest consumtion of noodle in the world. Noodle is made from imported wheat flour. However, there is a need to reduce the dependency of wheat flour by finding new sources to make noodle. Corn flour can be used as alternative besides its high content of betacarotene has health benefit for the human. Different from wheat flour which is contained gluten for dough formation, production of corn noodle need to be added with additive for replacing the function of gluten. This paper aimed to study hydrocolloids usedto improve corn noodle characteristics. The result noodle is then analyzed water content, ash content, cooking loss, breaking test, hedonic test. From the results of this analysis obtained the best sample by analysis of crude fiber content, protein content and beta-carotene content. The best samples obtained from this research are xanthan gum 2% treatment with 2.50 cm breaking test, moisture content 40.19%, 1.05% ash content, 2.21% cooking loss, 3.98% protein content, 4.16% crude fiber content, beta-carotene content 12.71 mg / L and hedonic test obtained colors , aromas, flavors and textures are all neutral.
