“…The decrease in glycerol levels also occurred at 7.5% and 10% sodium sulfite concentrations, namely 6.97±1.01% and 11.16±0.66%, but the results were not better than the 5% SS treatment. Mujdalipah et al [12] in their study stated that purification of MDAG based on glycerolysis of palm oil using the solvent extraction method could only reduce the free glycerol content from 4-8% to 2.40-3.05%. This proves that purification by the cream demulsification method is more effective in purifying MDAG resulting from glycerolysis to reduce free glycerol levels.…”

Glycerolysis is the simplest, least expensive, and most prevalent technique for producing mono-diacylglycerol (MDAG). MDAG, a product derived from palm oil, is crucial to the fat-based food sector. Chemical glycerolysis generally leaves crude MDAG with glycerol residues that exceed the European Union’s maximum (up to 7.5%); thus, it must be purified. Cream demulsification is one of the conventional ways of purification for separating glycerol residues from MDAG. This study investigates the impacts of adding electrolytes (calcium chloride, ammonium bicarbonate, magnesium sulfate, and sodium sulfite) and the effects of electrolyte concentration (2.5%, 5%, 7.5%, and 10% w/v) on the concentration of glycerol, monoglycerol, diglycerol, and triglyceride. Electrolytes have a role in transforming the MDAG emulsion system from a water-in-oil (w/o) system to an oil-in-water (o/w) system, causing the emulsion to break down and form cream. Glycerol and water create a polar phase (skim), whereas MDAG form a non-polar phase (cream). The analysis showed that the highest yield was obtained by adding 5% sodium sulfite (SS) electrolyte, which was 44.51±0.60%. Increasing the electrolyte concentration from 2.5% to 5% resulted in a larger yield, but a further increase of up to 10% did not improve the yield. The glycerol content also de creased from 13.36±0.82% to 1.8±0.32% with the addition of 5% SS electrolyte. This result is in line with the fact that the amount of MAG and DAG increased after the creaming demulsification with 5% SS electrolyte (41.68±1.23% and 25.75±0.26%, respectively).

“…Potensi PFAD juga dapat digunakan sebagai bahan baku dalam sintesis mono-digliserida (MDAG) yang merupakan salah satu jenis emulsifier yang banyak digunakan dalam industri pangan dan bukan pangan. Untuk memperoleh spesifikasi produk MDAG yang baik, seperti dalam aturan Uni Eropa pada Lampiran II dan Lampiran III Peraturan (EC) No 1333/2008 tentang aditif makanan standar Uni Eropa (UE) tahun 2012 (memiliki kadar monodan di ester minimal 70%, total gliserol 16-33%, kadar gliserol bebas maksimal 7%, bilangan asam maksimal 6% dan kadar air maksimal 2%), telah dilakukan pemurnian produk MDAG oleh Compton et al 2008;Setyaningsih et al 2015;Mujdalipah et al 2016;Solaesa et al 2016;Setyaningsih et al 2018;dan Zhang et al 2018. Namun, dalam sintesis dan pemurnian MDAG hasil sintesis tersebut masih diperoleh rendemen produk MDAG yang relatif rendah, sehingga diperlukan berbagai upaya dalam peningkatan rendemen produk MDAG hasil sintesis yang sesuai dengan spesifikasi.…”

“…Produk MDAG hasil sintesis, umumnya masih mengandung komponen ALB dan TAG yang cukup tinggi. Kedua komponen ini akan mengurangi kinerja MDAG sebagai pengemulsi, sehingga diperlukan proses pemurnian untuk mengurangi jumlah ALB dan TAG dalam produk (Mujdalipah et al 2016). Penghilangan fraksi ALB dan TAG dapat dilakukan melalui pemurnian dengan beberapa metode seperti penyabunan (reaksi asam lemak oleh basa kuat), kombinasi ekstraksi pelarut dan penyabunan, serta molekuler destilasi.…”

“…Pada proses kristalisasi, MAG dapat berperan dalam menghambat kristalisasi 1,3-DAG dan merangsang kristalisasi 1,2-DAG, yang dapat mengkristal dalam bentuk α dan β. Keberadaan dua polimorfik menghasilkan penurunan kekuatan jaringan kristal (Tavernier et al 2019). Mujdalipah et al (2016) Zhang et al (2018). Distilasi molekuler pada suhu moderat (150°C) memberikan konsentrasi PUFA 72 % tetapi menurunkan kadar 2-MAG menjadi 69,81 %.…”

Review Penelitian Tanaman Industri and characteristics of PFAD and its application in the synthesis of MDAG and the various efforts that can be made to improve the yield and specifications and the application of MDAG to multiple products for further research. Chemical synthesis of MDAG with a continuous process followed by purification of esterified products using the molecular distillation method has the opportunity to be done as an effort to increase the yield and specifications of MDAG products according to standards.

“…Hexane is one of the most common organic solvents used extensively for oil seeds extraction ( Danlami et al., 2014 ). Hexane has low melting point, easy recovery, high availability, and high solubility in oil corresponding to its non-polar properties ( Liu and Mamidipally, 2005 ; Mujdalipah et al., 2016 ).…”

In this work, the effect of solvent pre-treatment (hexane, petroleum ether and ethanol) on the physicochemical, thermal and morphology behavior of Mangifera pajang seed fat (MPSF) were investigated. Fat extraction was performed using Soxhlet method, and results showed that the yield, physicochemical, and crystalline structures of the MPSF were significantly (p < 0.05) influenced by the extraction solvents. Hexane gave the highest fat yield (7.67 %) with low unsaturation value (52.13 g iodine/g) compared with petroleum ether and ethanol. Hexane MPSF also had low oxidation rate (peroxide value of 1.1 mEq/g). Both non-stabilized and stabilized hexane MPSF showed a single melting endothermic peak at high temperature with onset, maximum peak and offset temperature of 16.23 ˚C-18.21 °C, 28.22 ˚C-31.25 °C and 34.85 ˚C-39.58 °C, respectively. Hexane MPSF crystallized rapidly at high temperature with single maximum peak starting at 16.51 ˚C-16.68 °C and ending at 0.23 ˚C-1.13 °C. In comparison with ethanol extract, hexane MPSF demonstrated a compact crystalline structure with a large densely packed center. Therefore, MPSF obtained from hexane presented better overall quality than those obtained from other extraction solvents. MPSF exhibited similar melting and morphological behavior to mango kernel fat and commercial cocoa butter. These results suggested that hexane was the best solvent for the extraction of MPSF. This fat also has the potential to be applied as a cocoa butter alternative fat or functional fat.
