    Step -5
    Here we take acid insoluble ash weigt.
    In this ash, filter paper ash is present.
    Why don’t we exclude it?
    If you measure in this way, the measurement can not be average?

      We used Ashless filter paper. Ash of filter paper can be seen but the ash is without any significant weight.

      1. First extract the fat of bakery product following our video entitled "Determination of Crude Fat" (You can find the video of fat extraction in our playlist 'Proximate Analysis'
      2. After fat extraction, determine the acid value of the extracted fat following our video entitled "Determination of Acid Value and Free Fatty Acid" (Check our video list to find the acid value)
      ****In this way, you can determine the acidity of extracted fat experiment for bakery product.

    Hi. Hope you are doing well. I have little query regarding this test method. I have reviewed different method for the same Test. Question is there why are you ignored moisture content in this test method. I have faced incorrect results for biscuits by your method. Kindly advise me.

    • @MicroChemsExperiments
      @MicroChemsExperiments  3 года назад

      This method is developed following the AOAC method strictly. No change is done. So dont keep confusion about the method. And moisture content is different thing, why would I consider moisture in Ash testing?
      But if you want to test your sample on dry basis then remove the moisture content from the sample first. Then take sample for Acid Indoluble Ash test. But dont forget to mention in your report that you did the test on dry basis.
      Thank you.

      40% HCl is used to dissolve the maximum ash content in acid which is passes through the filter paper with acid solution during filtration. Ash content which does not dissolved in 40% HCl trapped and retained on filter paper which further quatified as Acid Insoluble Ash.
