Chemistry is the study of the behavior. and

composition of matter. All foods are made up of

chemical substance which undergoes chemical

changes when cooking in an oven or digested 【1】______

within the body. The cooking of meat and

vegetables induce chemical changes, making 【2】______

it more delicious; similarly the leavening action of【3】______

baking powder is a straightforward chemical change,

as is the conversion of starch into sweet sugars

by digestion.

Cookery is a science requiring for knowledge 【4】______

of chemistry. This is evident from the variety of

cooking products and food additives available

as cooking oils, fats, colorings, sweeteners,

tenderizers, flavorings, screaming agents, preservatives,

etc. Each is carefully prepared before 【5】______

painstaking research.

It is therefore essential for trained cookers to 【6】______

understand chemical science in order to appreciate

the chemistry nature of foods and the changes 【7】______

achieving on cooking. Homeworkers should also 【8】______

know cleansing agents and textiles used in the 【9】______

home and how the latter responds to the effects 【10】______

of heat, light, water, and chemical cleansing agents.
