The diagram below shows the process of producing edible oils and fats, and margarine. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The diagram shows how edible

fats

and

oils

are made and shows all the stages involved, from collecting the raw

materials

to producing the

oils

and

fats

. There are nine stages in

this

process, which will be outlined below.

Firstly

, the raw

materials

,

such

as sunflowers, palm

oil

and nuts, are collected and transported by ship to a silo. At

this

point the raw

materials

are crushed and milled in order to extract the

oil

,

then

the

oils

are

then

filtered and steamed. It is at

this

point that the

oils

become edible. Different

oils

are made from

this

process, examples of which are coconut

oil

, sunflower

oil

and refined

oils

. These are used to make edible

oils

and

fats

which are

then

transported to supermarkets and shops to be sold.

Overall

, the process of making edible

oils

and

fats

largely entails cleaning and purifying in order for the

oils

to be fit for human consumption or

further

manufacturing processes.
