在医学实验室寻找香料新用途
VOICE ONE:
This is SCIENCE IN THE NEWS, a program in VOA Special English. I'm Bob Doughty.

And I'm Faith Lapidus. Herbs and spices help to sharpen the taste of many foods. Today, we tell about these food additives.
(MUSIC)
VOICE ONE:
People have used herbs and spices in food for thousands of years. Some of these substances are valued for their sharp taste. Others are chosen for their smell.
Generally, herbs come from the green leaves of plants or vegetables. Spices come from other parts of plants and trees. For example, cinnamon comes from the hard outer cover of cinnamon plants. The spice ginger comes from the part of the ginger plant that grows underground.
VOICE TWO:
Herb and spice plants grow in many countries. For example, the Molucca Islands in Indonesia are famous for producing spices like cloves, nutmeg or mace. Vanilla comes from plants growing in South America.
