Hi, Denis! Recently you wrote in a message to All:
... Mass fraction of milk fat minimum 10,5%.
So, what is this?
Mass fraction of milk fat? The wording seems rather odd to me too, but I'd break it down into manageable bits as follows:
mass = (in physics) a measurement of the quantity of matter. Mass
is often regarded as more or less synonymous with weight, here on
earth, but on other celestial bodies the gravitational forces are
different & our accustomed measurements of weight are misleading.
In domestic science what one needs to realize is that both food &
drink can be measured either by volume or by weight. If you look
at the nearest bottle of your favourite alcoholic beverage you'll
probably see something like "percentage of alcohol by volume". I
take it the percentage of milk fat in your example was calculated
by weight... but I don't know whether or not this is usual.
fraction = a numerical quantity which is not a whole number. This
term may be confusing to people who are accustomed to thinking of
fractions as e.g. 1/2, 2/3, or 3/4. But according to my CANADIAN
OXFORD DICTIONARY the word is also applied to decimals like ".5".
milk fat = butterfat, abbreviated to "BF" where I come from.
10,5% = 10.5% in English-speaking countries. In continental Europe
people often use commas where I'd use decimal points. That is how
the French handle such things & apparently they're not alone. :-)
