We have started using WMP to make up mixes. Having probs doing the calcs. You have no spreadsheets for WMP as an ingredient. Would you consider adding one?
 
Our calculations show MSNF on high side. Ideas?

Sue your post is only  the second query ( now lots of queries) I have had concerning the use of WMP in ice cream since the site was created! The first query in June 2010 was not posted on the forum and came from a person making ice cream in Asia. I quickly produced a spreadsheet- WMP + cream and found that under certain conditions that an error of more than 1% in the MSNF balance could be obtained due to the approximations used. Because of lack of time I used the Goal Solve option in Excel to write a simple Macro and produced a useful spreadsheet which was later further adapted by the person concerned. I suggest you consider doing this.
 
I have no plans  to produce a WMP spreadsheet at present but will do if there is sufficient interest.
 
Spreadsheets showing how to calculate the ingredients required to make mixes using WMP, cream and cream/vegetable fat mixes have been produced and can http://www.dairyscience.info/technology/180-excel-ice-cream.html" rel="nofollow - be downloaded from the site . Additionally a tutorial showing how to calculate these mixes from first principles has been produced and will be available shortly.

There has been a surprising level of interest in spreadsheets for working with WPM and cream. I have also had two enquiries about how to use both vegetable fat and dairy fat in mixes and I have added an additional http://www.dairyscience.info/technology/180-excel-ice-cream.html - two spreadsheets to show how to undertake these calculations.

Hello everybody.

I am new here and I have to say that the site is very usefull. I work with gelato. I am very satisfied with my product and dont need to change anything about it, but when I saw theese calculations I became courious to find the percentage of fat, sugat, especialy msnf on my gelato, but I found it hard. I use whole milk powder which is about 26% fat and cream (vegetable - liquid) which is 30 % fat. The difficulti started just in the begining when I tryed to calculate the serums needed, cs the cream is liqud and also there are other liquides. Also i cant calculate the % msnf in my whole milk powder cs it looks to me a little bit unlogical if there is 26% fat, than no way there can be 97% MSNF. Any help would be welcomed.

Thank you in advance

Welcome to the forums.
 
1. I am not sure where you got your value for MSNF for whole milk powder (WMP); your value as you suspect is incorrect. The MSNF of WMP can be obtained by subtracting the fat and moisture values from 100. Assuming 3% moisture and 26% fat your WMP should have a MSNF of 71%.
 
2. Ice cream mix calculations are fairly easy to do providing you understand the basics. The principles of the calculations are http://www.dairyscience.info/ice-cream-/154-ice-cream-mix.html - described on this site . The calculations using WMP and cream are slighter more difficult but still easy to do. Note http://www.dairyscience.info/newCalculators/calculator/index.php - the free 'lite' ice cream mix calculator has not been configured to work with whole milk powder but this option can be http://www.dairyscience.info/calculator1/index.php - negotiated for the subscription calculator.
 
3. You can also http://www.dairyscience.info/technology/180-excel-ice-cream.html - download an Excel spreadsheet configured to work with WMP and cream.

Mr. Michael, I have tryed all the menthodes you suggested me, but it seems it doesnt work. We I have to multiply with 0.09?? I think this what confuses me! There is no example with WMP so I find it very difficult. Do you have any spreadsheed usein WHMP, watter and Cream?

Any help would be welcomed!

Thank you in advance

Pack 6 of the Excel spreadsheets available on this site contain customised spreadsheets for product development / small batch mix manufacture designed to work using whole milk powder and cream as the major ingredients. With the exception of the macro code (needed to fine tune the MSNF mass balance) all the calculations are shown. You can download from http://www.dairyscience.info/technology/180-excel-ice-cream.html - here. However, a small contribution towards site running costs is required
I am not aware of any worked example apart from my spreadsheets that show how to do calculations using cream and whole milk powder. I will consider adding an example to this site but currently there is little interest in this ingredient combination.

I have had a surprising number of Emails asking for information on how to calculate mix formulations using whole milk powder (WMP) and cream or mixtures of cream and vegetable fat. Despite my reminders that there are two Excel spreadsheets on the site that can be used to undertake most mix calculations using WMP there is some interest in finding out how to do these calculations from first principles.
 
None of the queries were from students.
 
I have prepared a tutorial showing how to work out the ingredients required to obtain  a mix specification containing WMP and a series of On Line calculators to illustrate how to undertake the calculations.
 
The quantities of WMP and cream are calculated by solving a simple simultaneous equation.
 
The tutorial will be available shortly.
