Title: How Dalda mGhee is produced?
Post by: ABM Nazmul Islam on December 07, 2014, 12:54:50 PM

Number of double bonds in oils and fats affects physical property such as melting point,
crystallinity. Generally, double bonds reduce the oil’s melting point. Therefore, oils rich in
unsaturated fatty acids are liquid, while ones with small amount of unsaturated fatty acids
are solid or semi-solid.

Hydrogenation is a process to add hydrogen atoms into double bonds of unsaturated fatty
acids (Figure 3-2-1). As the result of hydrogenation, liquid oil becomes solid or semi-solid. A
typical example of hydrogenation is in the process of margarine and shortening production.
Vegetable oil is hydrogenated with gaseous H2 in the presence of a metal catalyst (usually
nickel catalyst).
