During my proposal defense presentation, on of the examiner ask me to include the analysis on moisture content of my extract before and after the drying process is done.
Im basically want to do a simple extraction process to get a crude extract using ethanol.
So, Im just wondering, what is the importance of the moisture content?
I will be using the crude extract as an additive for improving the properties of a coating, as such I dont really think the moisture content will affects its usage in later procedure.
Anyways, can anyone share about it? Thank you!
Hello I guess the moisture content he asked you is just for you to ensure that your drying done after extraction is done! Otherwise, as you said when you do the ethanol extraction, it should not be wet! unless you make an extraction on the already dried plant, this in my opinion will go to a possible analysis of the moisture content. Good luck for the future.
Dear Wan Mohamad Ikhmal, in addition to what Kouwelton Patrick Koné noted, moisture content determination will help you estimate the total solid matter which is a useful indices in knowing the exact weight of fresh matter used to yield the dried matter. As such one can easily replicate the work.
If you are extracting the plant material by Ethanol then it is important to know that how much moisture present in plant/herb. More moisture ultimately dilute ethanol.
