The processed oil from the coconut plant is generally understood as coconut oil. A method is required to produce a product with a higher oil extraction rate and is able to reduce the water content and free fatty acids in the coconut oil production. It is also necessary to add substances that can delay or prevent fat oxidation reactions by generating substances in the form of antioxidants. The method that can be implemented is the enzymatic method employing the bromelain enzyme in a pineapple with the addition of an antioxidants substance from the kesum  leaf. The objective of this research is to describe the quality of coconut oil after the addition of pineapple (ananas comosus) and kesum leaves (polygonus minus) extracts. The parameters for describing the quality of the oil are the organoleptic test, the degree of acidity, the oil extract rate, the peroxide number, the saponification number, and the acid number. This research is a quasi-experiment. The samples in this research were coconut oil without the addition of pineapple fruit extract, coconut oil with the addition of pineapple fruit extract without the addition of kesum leaves, and coconut oil with the addition of pineapple fruit extract and kesum leaves as much as 20gr, 30gr and 40gr. Based on the statistical results of the linear regression test, it was discovered that p-value = 0.000 <0.05, so it was concluded that there was an effect of the addition of pineapple fruit and leaves of kesum on acid number content with an effect of 76.4% on the acid number, 71.4% on the peroxide number, and 81.5% to the saponification number. It is recommended to test the water content, free fatty acids, and iodine number.

The aim of our work was to study the quality of vegetable oils - unrefined sunflower oil (grade I) and soy hydrated oil (grade I). One of the stages of the study was to determine the quality of vegetable oils - peroxide value (characterizes the amount of primary oxidation products of fats - peroxide compounds) and acid number (characterizes the total content of free fatty acids) in the samples of vegetable oils. The acid number was determined by titration (neutralization) of free fatty acids with alkali in the presence of an indicator (phenolphthalein). The peroxide number was determined by titration of the isolated iodine with a solution of sodium thiosulfate. Each study was reproduced 5 times. First of all, the quality indicators of oils (acid number and peroxide number) were determined in samples of fresh oils. Subsequently, the oil was kept for 3 months (in compliance with the recommended requirements for storage of oils and without compliance with the requirements for storage of oils) and re-determined these indicators. The quality of the investigated vegetable oils was determined by the indicators of acid number and peroxide number in accordance with the established requirements of the State Standards of Ukraine (DSTU EN ISO 660: 2009; DSTU 4570: 2006). The results of our research show that the level of acid number and peroxide level in samples of fresh oils meet the requirements of the State Standards of Ukraine (DSTU EN ISO 660: 2009; DSTU 4570: 2006) for this type of oil, which confirms the quality of oils and compliance with production , processing and transportation. It is shown that in the samples of aged oils (3 months, subject to storage requirements) the level of acid number and the level of peroxide number increases within normal limits. However, in the samples of aged oils (3 months, without compliance with storage requirements) there is a significant increase in the level of acid number and peroxide number, which does not meet the requirements of State Standards of Ukraine. As a result of research it is shown that the quality of vegetable oils depends on compliance with the recommended norms and conditions in the process of production, processing, transportation and storage. It is proved that under the conditions of violation of the recommended norms of storage in samples of high-quality vegetable oils the level of quality indicators of vegetable oils - acid number and peroxide number significantly increases.

Spoilage of coconut oil is indicated by rancidity caused by the oxidation and hydrolysis reactions. One of the efforts that can be carried out to inhibit the rancidity is by adding a natural antioxidant, such as carrot (Daucus carrota L) powder, into the coconut oil. This research aimed to find out the effect of the addition of carrot powder into the coconut oil on some parameters namely iodine number, peroxide number, FFA level, acid value and water content. The coconut oil was prepared by heating technique followed by the addition of carrot powder in the ratio of coconut oil:carrot of 100:1, 100:2, 100:3, 100:4, 100:5, and coconut oil:BHT (Butyl Hydroxy Toluene) of 100:1 as the positive control. The results were then compared to the Indonesian National Standard of SNI 01-2902-1992. It was found that the coconut oil added with carrot powder in the ratio of 100:4 showed the best quality with iodine number of 8.4092 ± 0.5761g iodine/100g, peroxide number of 3.2363 ± 1.9168mg O2/100g, Free Fatty Acid level (FFA) of 0.1676 ± 0.0037 %, acid value of 0.4656 ± 0.0119mg KOH/g and water content of 0.1038 ± 0.0068 %. The characterization using FTIR (Fourier-transform infrared spectroscopy) of such quality of coconut oil indicated some functional groups of OH, CH, CH3, C=O, CºC aliphatic and C=C aliphatic were contained.

Abstrak. Dalam rangka meningkatkan komoditas susu di Indonesia, pemerintah menargetkan sapi perah lokal harus mampu menyuplai 41% produksi susu dalam negeri pada 2022. Salah satu cara untuk menaikkan produksi susu sapi adalah memberikan suplemen pakan berupa sabun kalsium. Sabun kalsium telah banyak digunakan di luar negeri, namun tidak di Indonesia, untuk menaikkan produksi susu sekaligus fertilitas ruminansia. Sabun kalsium dapat dibuat melalui reaksi fusi termodifikasi antara Palm Fatty Acid Distillate (PFAD) sebagai sumber asam lemak bebas dengan sumber kalsium. Penelitian ini mengevaluasi pengaruh jenis PFAD terhadap kualitas produk sabun kalsium. PFAD yang digunakan berasal dari beberapa industri pengolahan kelapa sawit di Indonesia, yaitu Kabupaten Sidoarjo, Kabupaten Bekasi, Kota Bekasi, dan Kabupaten Pelalawan dengan rentang angka asam 195–221 mg KOH/g sampel. Produk sabun kalsium yang dihasilkan kemudian dianalisis nilai angka asam untuk menguantifikasi kualitasnya. Keempat produk sabun kalsium secara keseluruhan memiliki angka asam di bawah 1 mg KOH/g sampel. Rendahnya angka asam pada produk membuktikan bahwa keempat sumber PFAD dapat digunakan sebagai bahan baku pembuatan sabun kalsium dengan kualitas baik. Kata kunci:angka asam, kalsium oksida, PFAD, pakan ruminansia, sabun kalsium. Abstract. Calcium Soap from PFAD for Ruminant Feed: Quality of PFAD as a Source of Free Fatty Acids. In order to increase the milk commodity in Indonesia, the government targets local dairy cattle to be able to supply 41% of domestic milk production by 2022. One way to increase the production of cow's milk is to provide a dietary supplement in the form of calcium soap. Calcium soap has been widely used overseas, but not in Indonesia, to increase milk production as well as ruminant fertility. Calcium soaps can be made by modified fusion reactions between PFAD as a source of free fatty acids with a calcium source. This study evaluated the effect of PFAD type on the quality of calcium soap products. PFAD used were obtained from several palm oil processing industries in Indonesia, namely Sidoarjo regency, Bekasi regency, Bekasi city, and Pelalawan regency with the acid number 195–221 mg KOH/g sample. The resulting calcium soap product is then analyzed for the acid number to quantify its quality. The four calcium soap products had an acid number below 1 mg KOH / g sample. The low acid number in the product indicates that the four sources of PFAD can be used as raw material for producing calcium soap with good quality. Keywords: acid value, calcium oxide, calcium soap, PFAD, ruminant feed.

When edible oils are heated above 150°C, they undergo thermo-oxidative changes depending on a variety of factors, such as temperature, heating time, type of oil, etc. These changes cause a series of chemical reactions (hydrolysis, oxidation, polymerization, etc.) resulting in the formation of free fatty acids, an increase in the peroxide number and the acid number, a change of color and a decrease in the iodine number. This study investigates changes of the content of free fatty acids, the acid number, and the peroxide number in edible sunflower oil when heating at the temperature range from 110°C to 190°C for 30 minutes, as well as after the adsorption by a natural and a synthetic adsorbent (clinoptilolite and zeolite 4A). The results of the research show that these adsorbents are effective in removing the products of chemical reactions occurring in thermal degradation, which is particularly evident after the adsorption of oil heated at 190°C. Somewhat better results were achieved after the adsorption using clinoptilolite, with a 72 % reduction in the content of free fatty acids, 83 % reduction in the acid number, and 43 % reduction in the peroxide number. After the adsorption by zeolite 4A, the content of free fatty acids was reduced by 65%, the acid number by 76 %, and the peroxide number by 39 %. The results obtained open the possibilities of further research aiming at discovering the adsorbents which would be most suitable for the regeneration of used edible oils, after which they could be applied safely for different purposes.

The clove leaves are part of the clove plant which rarely used, and if you look at them, the clove leaves have active compounds that can be functioned as antibacterials. Meanwhile, Virgin Coconut Oil or called VCO, is processed from coconut milk as the essential ingredient, and if it is not processed correctly, VCO will usually have a short shelf life or can be damaged quickly. This study aims to determine the quality of VCO by adding clove leaves in its processing. Based on the results of the study, it can be seen that the quality of VCO with the addition of clove leaves for the indicator of water content and the free fatty acid number is not following the Indonesian National Standard (SNI). In contrast, the indicator for the VCO peroxide number with a mixture of clove leaves has good quality according to the SNI standard. Based on the results of the study, it can be seen that the quality of VCO with the addition of 100 grams of clove leaves for indicators of water content and fatty acid numbers, namely 2.9% and 0.69%, is high or above the SNI standard limit. In comparison, the quality of VCO with the addition of 100 grams of clove leaves with indicators a peroxide value of 0.7 mg ek/ kg or less than 2 mg ek/kg has good quality based on Indonesian National Standard. Keywords: Quality, VCO
