Question - How Butter Is Made ?
Answer -
Butter is made by churning pasteurized cream. During churning the cream becomes more viscous and finally a mass of solid butter is produced. The liquid by-product, known as buttermilk, is removed and the butter is mixed to give the desired consistency. Salt and colouring matter may be added at this stage, although some butter is sold unsalted.
The churning or agitation process reverses the emulsion. Cream is an emulsion of fat globules dispersed in a water phase. During churning the fat globules aggregate and form a solid phase which is interspersed by small water droplets. Butter is therefore a water-in-fat emulsion.
