Shouldn't the weight of filter paper be considered here, the final weight when the crucible weight is subtracted, we get the weight of acid insoluble ash+filter paper, right?

Hello .I am looking for the purpose of this control. and on what samples on sconces. did you have the water insoluble ash method for spices. thanks you
This test represents the type of minerals in a sample left after dissolving in acid. We tested feed sample in this video. You can determine the Water insoluble ash by following video except you have to use hot water in place of HCl solution.
I am very impressed with your easy methods with calculation. So nice of you. Miss can you share the acidity of extracted fat experiment for bakery product. I shall wait for you positive response. Thanks.
Irfan Ali, Thank you for your comment. I can guide you to the experiment you mentioned. Videos are already uploaded. Do the following: 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.
Samir Sakir, we used ashless filter paper. So the weight of filter paper ash is zero. Thats why no weight of filter paper will be counted in the final ash content.
Joshi Nirav, Thanks for commenting here. Ashless whatman paper should be used. Full properties of the filter paper is shown in the cover of the filter paper in this video. Please take a look at it.
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.
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.
@@IrfanAli-xy5bf AOAC method is world's best analytical method. AOAC did not consider moisture. May I ask you, in which method you got to consider moisture content?
Sir. Actually I am lab analyst in biscuit industry, so am wanting to determine the acid insoluble ash in biscuit. Then I followed to fassi methods for cereal ( biscuits , on page no 28 ) in this method they have to calculate the moisture content in formula. Sir you can see.
@@IrfanAli-xy5bf Ok I got it. If they consider moisture content then their result will be on dry basis. You can also consider moisture content in the calculation then you have to mention in your test report that you have analyzed your sample on dry basis. But if you analyze following my method then you dont have to mention anything. Because In AOAC the moisture is not considered.
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.
Om Prakash, Thank you for your comment. We need to know the acid insoluble content of food to know the amount of minerals, present in a food sample, which is not hydrolysed by the acid.
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.
@@MicroChemsExperiments ohh.

Shouldn't the weight of filter paper be considered here, the final weight when the crucible weight is subtracted, we get the weight of acid insoluble ash+filter paper, right?
We used Ashless filter paper. The ash of the filter paper is weightless. Thats why we did not consider the ash of the filter paper
@@MicroChemsExperiments gotchya👍
@@MicroChemsExperiments how is it weightless though? The matter is still there!

@@MicroChemsExperiments I did and it was weightless, I will search on google though, thanks
What if If I do not have an ashless filter paper close.
And can I use this method for checking ash content in feed pellets?
Use normal filter paper and make ash of that same size of filter paper (blank) separately. Substact blank weight from sample.
Thank you for your experience benefit vedio
Thanks again

Yes
Hey shouldn't we substract the weight of the filter paper from 'w2' ?
No. We used an ashless filter paper. So weight of the filter paper after burning is zero
Thanks 👍

Hi, how long it takes approximately to get the result??
Cooling of furnace needs time. So about 26 hours needed in total.
Filter paper ka bhi weight aa gya hoga last me? Filter paper ka weight nhi liya tha apne phle??
Filter paper ash is not included because this is ashless filter paper. After making ash, the weight of filter paper will be zero.
