Lipids - G. Modifications of fats and oils - Intereserification
6 important questions on Lipids - G. Modifications of fats and oils - Intereserification
What do you need to let the interesterification reaction take place?
A better option is to use a n catalysis like sodium hydroxide, sodium alcoholates.
What are the different steps in the interesterification process?
- Formation of anion (R-O-)
- Interesterification
- Intraesterification
What is the difference between intra and inter esterification?
Inter is a exchange of fatty acids between differ triglycerides
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the effect of interesterification?
- A higher melting point
- A more homogeneous triglyceride composition.
You see a mix of palm and sunflower oil. Which one is interesterified and which one is not?
Therefore D is interesterified.
Also the LLL went down and you have higher peaks in the end what indicates an higher melting point. This also indicates interesterification. HOWEVER this is not a general rule.
Fractionation and then interesterification leads to four different products:
- palm oil, interesterified & not
- palm olein, interesterified & not
M myristic (14:0),
P palmitic (16:0),
St stearic (18:0),
O oleic (18:1),
L linoleic (18:2).
S saturated, U unsaturated fatty acids.
Which products are the interesterified, products A1 & B1 or products A2 & B2. Explain your choice. (4 pts)
