What Is But­ter?

Consumer Voice - - Test Report -

But­ter is the smooth, fatty sub­stance ob­tained from churn­ing cream. But­ter man­u­fac­tur­ers first pas­teurise the cream. This heat treat­ment de­stroys bac­te­ria, in­ac­ti­vates en­zymes, and gives the cream a cooked or heated flavour. Qual­i­ta­tively, the com­po­si­tion of but­ter is roughly 80 per cent fat (mostly sat­u­rated), 12 per cent wa­ter, 2 to 3 per cent non-fat milk solids (lac­tose, pro­tein), and 2 per cent added salt. It is the most con­cen­trated of dairy prod­ucts, con­tain­ing about 740 kilo­calo­ries per 100 grams (210 kilo­calo­ries per ounce). But­ter is a valu­able source of vi­ta­min A, plus it has a lit­tle vi­ta­min D. It is also a source of di­etary choles­terol. Vi­ta­min con­tent is higher in sum­mer, when the cat­tle feed on fresh grass.
