Mandar coconut oil is one of the coconut processed products, which has become superior product in West Sulawesi especially in Majene regency. Unfortunately, the Mandar coconut oil can’t be used more than a month because the water content and free fatty acid content of the oil have exceeded the maximum standard of SNI, so it can adversely affect on health. On the other hand, the existence of rice husk in Indonesia itself especially in West Sulawesi has not received attention and is limited to a few needs such as for ash or livestock feed, and the rest is thrown away. This research aims to determine the effect of rice husk ash addition on the increasing of Mandar coconut oil quality. Completely randomized design was used in this research with 6 rice husk ash concentration variation levels i.e. 0%, 5%, 10%, 15%, 20% and 25%. The result shows that the addition of rice husk ash with 10% to 25% can reduce the water content of the oil until the quality standard of SNI is full filled. The highest reduction of water content was reached with 25% of rice husk ash concentration with 81% of reduction percentage. While, the addition of rice husk ash with 15% concentration can reduce the free fatty acid content of Mandar coconut oil until 32%.

ABSTRACT Virgin Coconut Oil (VCO) is coconut oil that is processed by controlled heating or can be produced without heating (fermentation) so that it does not change the composition or aracteristics of the oil. The purpose of this study was to determine the effect of fermentation time on the physical and chemical properties of VCO. This research includes two stages. The first stage is producing VCO based on fermentation time with raw materials such as coconut and tempeh yeast. The second stage performs physical and chemical analysis which includes yield, water content, free fatty acid content and density. This study used a Simple Completely Randomized Design with 1 fermentation time factor (L). There are 4 fermentation times used, namely L1 = 24 hours, L2 = 36 hours, L3 = 48 hours, L4 = 60 hours with 4 replications to obtain 16 experimental units. Further test using DMRT. The results showed that all yields were above 16%. Fermentation time significantly affected the yield, water content, free fatty acid content but had no effect on density. The best results were shown in VCO with 48 hours of fermentation time, namely yield of 21,843%, water content of 0,238%, free fatty acid content of 0,149% and density of 0,892 g/ml. ABSTRAK Virgin Coconut Oil (VCO) adalah minyak kelapa yang diproses dengan pemanasan yang terkontrol atau dapat dihasilkan tanpa pemanasan (fermentasi) sehingga tidak mengubah komposisi atau karakteristik minyak. Tujuan penelitian ini adalah mengetahui pengaruh waktu fermentasi terhadap sifat fisik dan kimia pada pembuatan VCO. Penelitian ini meliputi dua tahapan. Tahap pertama memproduksi VCO berdasarkan waktu fermentasi dengan bahan baku berupa kelapa dan ragi tempe. Tahap kedua melakukan analisis fisik dan kimiawi yang meliputi rendemen, kadar air, kadar asam lemak bebas dan densitas. Penelitian ini menggunakan Rancangan penelitian Acak Lengkap sederhana dengan 1 faktor waktu fermentasi (L). Waktu fermentasi yang digunakan ada 4 yaitu L1 = 24 jam, L2 = 36 jam, L3 = 48 jam, L4 = 60 jam dengan 4 ulangan sehingga diperoleh 16 unit percobaan. Uji lanjut menggunakan DMRT. Hasil penelitian menunjukkan semua rendemen diatas 16%. Waktu fermentasi berpengaruh nyata terhadap rendemen, kadar air, kadar asam lemak bebas namun tidak berpengaruh terhadap densitas.

Liquid Liquid Extraction

Liquid–liquid extraction of vegetable oil with ethanol predominantly removes the components having the greatest affinity for ethanol, such as free fatty acids responsible for the acidity of oil, but also some contaminants such as phthalates. The aim of this work is to study the effect of several operating parameters on the deacidification process: the initial free fatty acid content in oil (3.1, 5.8, 7.6 and 11.7% OA eq.), the ethanol-water content in solvent (70.0/30.0, 80.0/20.0, 87.8/12.2 and 95.6/4.4 g/g), and the oil/solvent ratio (0.50, 0.75 and 1.00 g/g). The economic assessment of the deacidification based on the costs of distilling solvent and neutral oil loss showed that the use of solvents containing 82 to 90 wt.% of ethanol enables to achieve a trade-off between efficiency of the extraction of free fatty acid and the neutral oil losses. A three-stage crosscurrent extraction using a solvent at 88.6 wt.% of ethanol (global solvent/oil ratio: 8.0 g/g) reduced the free fatty acid content from 5.8% OA eq. (in crude walnut oil) to 0.3–0.4% OA eq. with a loss of 4.0% of neutral oil mass. Regarding the extraction of phthalates, our results showed that the lower the water content in the hydroethanolic solvent, the more efficient the extraction of butyl benzyl phthalate (BBP). Moreover, extraction with ethanol has successfully reduced the BBP content below the current regulatory limit.
