Homogenisation includes passing of milk by means of a small valve at great strain.

The course of disrupts the fat globules. The science applied here is the creation of more room for the floor area of the flat globules, which makes it attainable for proteins to get absorbed by the surface occupied by fats globules.

The results of the research showed that the addition of milk to coffee didn’t have any effect on polyphenol bio-availability. However, while adding a non-dairy creamer to espresso delayed the time the polyphenol equivalents appeared inside the blood, it didn’t affect to general quantity delivered. To sum up, polyphenols ultimately reached the bloodstream regardless of which coffee was consumed.

Evaluating the Results

Coffee is one of the most effective sources of antioxidants, especially polyphenols, and antioxidants are essential in maintaining the physique wholesome. The research by Nestle researchers lastly showed that an equal amount of polyphenols is delivered in the black coffee and the alternative of espresso without milk.
