The objective of this research was to assess the photodegradation kinetics of chlorophyll, tocopherol, and carotenoid in red palm oil (RPO) during storage under flourescent light intensities of 5000, 10000, and 15000 lux. Photodegradation was followed by measuring the changes of chlorophyll, tocopherol, and carotene contents in RPO filled in transparent bottles stored in incubator box (31.60±0.69 oC) with controlled light intensity. As reference, pure RPO was filled in dark and transparent bottles then was stored at roomy temperature (31.46±1.04 °C) and lighting (476.25-484.89lux). The result showed that photodegradation of chlorophyll followed first order kinetics with two distinct photodegradation periods. First, rapid photodegradation period during the first 6 hours of storage with k values of 3.81x10-2, 4.45x10-2, 5.64x10-2 day-1, followed by a slower photodegradation period at prolonged storage more than 6 hours, with k values of 1.41x10-2, 3.01x10-2, 4.59x10-2 day-1 under light intensities of 5000, 10000, and 15000 lux, respectively. Photodegradation of tocopherol and carotene also followed first order kinetics. Photodegradation of tocopherol had the highest rate constant (k value of 9.10x10-2, 12.02x10-2, 17.33x10-2 day-1), meanwhile carotene had the lowest rate constant (k value of 0.80x10-2, 1.40x10-2, 1.98x10-2 day-1) under light intensities of 5000, 10000, and 15000 lux, respectively. The light intensity coefficient (zi) as dependence indicator of k on the changes of light intensity were measured. The zi values ofchlorophyll, tocopherol, and carotene were 20000, 33333, and 25000 lux, respectively; indicated that the degradation rate of chlorophyll was the most sensitive to the changes of light intensity. ABSTRAKPenelitian ini bertujuan untuk mengkaji laju fotodegradasi klorofil, tokoferol, dan karoten dalam minyak sawit merah (MSM) selama penyimpanan dalam kondisi terpapar cahaya fluoresen pada intensitas 5000, 10000, dan 15000 lux. Fotodegradasi dikaji dengan mengukur perubahan kadar klorofil, tokoferol, dan karoten MSM pada botol transparan yang disimpan dalam kotak inkubator (31,60±0,69 oC) dengan intensitas cahaya dipertahankan konstan. Sebagai pembanding, MSM murni dalam botol gelap dan transparan disimpan pada suhu (31,46±1,04 °C) dan pencahayaan normal laboratorium (476,25-484,89 lux). Hasil penelitian menunjukkan bahwa klorofil mengalami fotodegradasi mengikuti model reaksi ordo pertama dalam dua periode; yaitu periode fotodegradasi cepat selama penyimpanan 6 jam pertama dengan nilai konstanta laju (k) 3,81x10-2, 4,45x10-2, 5,64x10-2 hari-1, diikuti periode fotodegradasi lambat pada penyimpanan yang lebih lama dengan nilai k 1,41x10-2, 3,01x10-2, 4,59x10-2 hari-1 masing-masing pada intensitas cahaya 5000, 10000, dan 15000 lux. Fotodegradasi tokoferol dan karoten juga mengikuti model reaksi ordo pertama. Fotodegradasi tokoferol berlangsung dengan laju paling tinggi (nilai k 9,10x10-2, 12,02x10-2, 17,33x10-2 hari-1), sedangkan fotodegradasi karoten berlangsung dengan laju paling rendah (nilai k 0,80x10-2, 1,40x10-2, 1, 98x10-2 hari-1) masing-masing pada perlakuan intensitas cahaya 5000, 10000, dan 15000 lux. Konstanta intensitas cahaya (zi) sebagai indikator ketergantungan nilai k terhadap perubahan intensitas cahaya untuk klorofil, tokoferol, karoten berturut-turut adalah 20000, 33333, dan 25000 lux. Hal ini mengindikasikan bahwa laju degradasi klorofil paling sensitif terhadap perubahan intensitas cahaya.

Indonesia is the world’s largest crude palm oil (CPO) producer and consumer in 2014. Components that affect the quality of CPO are diglycerides (DAGs) and free fatty acids (FFA). DAGs in palm oil are known as the precursor of 3-MCPD esters, while higher content of FFA could influence the oil stability. The contact of CPO with adsorbent could affect the present of DAG and FFA in CPO. The purpose of this study was to determine the best type of adsorbent in reducing DAGs and FFA in CPO with emphasis on the characteristics of the adsorbent and adsorbate. This study was carried out by using three different types of CPO quality and six different types of adsorbent (carbon active, MgO, Magnesol R-60, and 3 types of bleaching earth). The contact process of CPO with different adsorbents were carried out at a temperature of 50-60 °C (without vacuum) for adsorbents selection and 90 °C (under vacuum) for 30 minutes at a dose of adsorbent 1 and 3 %. The contact process of different adsorbents with CPO have not been able to reduce both DAGs and FFA significantly at the non vacuum condition in three differents CPO sample. The combination of MgO and bleaching earth type 1 could reduce FFA up to 70 % reaching the content of 14 % at vacuum conditions, but did not reduce DAGs of CPO. Different CPO quality and adsorbent characteristics will affect the reduction process of FFA and DAGs. ABSTRAKIndonesia merupakan negara produsen sekaligus konsumen minyak sawit kasar (Crude Palm Oil/CPO) terbesar di dunia pada tahun 2014. Salah satu komponen yang mempengaruhi kualitas CPO adalah digliserida (DAG) dan asam lemak bebas (ALB). DAG dalam minyak sawit adalah prekursor pembentuk senyawa karsinogen 3-MCPD ester, sedangkan ALB yang tinggi dapat mempengaruhi stabilitas minyak. Proses kontak adsorben ke dalam CPO akan mempengaruhi keberadaan kedua komponen tersebut. Tujuan penelitian ini adalah untuk menentukan jenis adsorben yang paling baik dalam mengadsorp digliserida dan asam lemak bebas dalam CPO dengan menitikberatkan pada karakteristik adsorben dan adsorbat. Penelitian dilakukan terhadap 3 jenis CPO (nilai ALB: 4, 6, dan 14) dan 6 jenis adsorben (arang aktif, MgO, Magnesol R-60, dan 3 jenis bleaching earth). Proses kontak dilakukan pada suhu 50 – 60 °C (tanpa vakum) untuk seleksi adsorben dan 90 °C (dengan vakum) selama 30 menit dengan dosis adsorben 1 dan 3 %. Proses kontak adsorben pada CPO dengan kondisi adsorpsi tanpa vakum belum dapat menurunkan DAG dan ALB secara signifikan terhadap ketiga jenis CPO. Kombinasi antara adsorben bleaching earth tipe 1 dan MgO dapat menurunkan ALB hingga 70 % pada CPO dengan ALB 14 % pada kondisi vakum, tetapi tidak dapat menurunkan DAG. Karakterisitik CPO dan adsorben mempengaruhi proses reduksi ALB dan DAG.

Cream demulsification is one of the purification method for separating the glycerol residue contained as emulsion with MDAG’s product. This method could be used to break emulsion system by adding electrolyte solution. This research aims to compare the performance of calcium chloride and calcium nitrate as electrolyte solution that is used in the process of cream demulsification. MDAG used was Fully Hydrogenated Palm Kernel Oil (FHPKO) from glycerolysis process. Based on student t-test, there was no significant difference (p>0,05) detected between the products of cream demulsification method using calcium nitrate and calcium chloride as electrolyte solution. It was discovered that calcium nitrate reduced residual glycerol from 11,69±0.88% to 0,57±0,07%; with characteristics of MDAG’s products were free fatty acid (ALB) of 8,51±0,94%, monoacylglycerol (MAG) of 31,53±3,27%, diacylglycerol (DAG) of 19,46±0,52%, triacylglycerol (TAG) of 39,93±4,66% and yield of 81,00±3,61%.respectively. In other hand, calcium chloride reduced residual glycerol from 11,69±0,88% to 0,64±0,06%; with characteristics of MDAG’s products were ALB of 8,91±0,71%, MAG of 9,79±1,97%, DAG of 19,16±0,53%, TAG of 41,49±3,24% and yield of 80,00±4,00%, respectively. Therefore, calcium nitrate can be to replace calcium chloride as electrolyte solution in cream demulsification method, especially in reducing the glycerol residue.
