0.01-0.07 Hi Hello everybody. My name is Professor Abd Karim Alias from Universiti Sains Malasia.
0.08-0.16 And in this lecture what talk about the processing of fats and oils with focus on the extraction process.
0.18-0.22 OK let’s start by looking at the overview of the process of oils processing.
0.23-0.38 So basically we start with the raw material .The raw material can be the seed example from soy been seed or the cotton seed sun flower seed oils palm fruit.
0.39-0.49 Then the oil likes to be squeeze out from the raw material so for this purpose we can use two type of extraction.
0.50-0.59 We can use organics solvent extraction will extract the fat oils from the fruit oil from the seed .
1.00-1.22 And another process without using solvent which is basically physical extraction so usually this using mechanical press for example screw press to expell or to extract the oil physically out from the seed or from the oil.
1.23-1.29 At the end of the extraction process what will get is a crude oil.
1.30-1.50 So the crude oil usually contain of teams insoluble component sush as free fatty acid FFA oil can contain phospholipid a lot of pigment and moisture so this something that is undissoluble.
1.51-2.11 So the next process to purify the oil and basically what is called stage or the process of refining to refine the oil to remove as much as possible dissoluble from the crude oil.
2.11-2.20 So the first stage basically the first step of the oil processing is to extract the oil to get crude oil.
2.21-2.31 Then after that refining then the second major stage in the oils processing is the modification .
2.33 The objective of modification is to modify properties of the oil to produce oil product with different physical properties most some of these modification a process for example
2.55 hydrogenation is a very widely use processing industry to increase the melting point and solid fat content of the fat.
3.06 so usually we use this process to produce product like magarine.
3.12 Then also intake vacation(ไม่แน่ใจ ) process and also fractionation process so the idea of this modification process is to produce various type of oil products which has higher value and which can be use for many fortification(ไม่แน่ใจ)
