I have to make extracts of grape seed and guava residues. I have seen different extraction techniques but berely understand any. Can someone guide me that how can I make grape seed extract and guava residue extract (includes; guava peel, pomace, seeds)
Can give more details. What is the purpose of the extract?
this will help to provide more related answers.
Also the terminology is quite confusing, one is seed and other one is called ‘residue’ extract. What is the difference or why is there a difference between these two?
