Which is the best method to determine water content like oven ? Karl fischer ? Or any other?? Plz suggest.
Because sample preparation looking critical to determine water content of gummies by oven and KF method...
I'd go for the heating in the oven.
Simply weight the gummy, put into an oven (but what temperature?) and then weight several times (to make sure the weight doesn't go down anymore).
I don't think you need any special preparation of your sample.
Can also try the Dean & Stark Method to determine moisture
