CHAPTER ONE
1.0 INTRODUCTION:
A sugar substitute is a
food additive that duplicates the effect of sugar in taste, usually with less
food energy. Some sugar substitutes are natural and some are synthetic. Those
that are not natural are in general, called artificial sweeteners. Artificial
sweeteners and other sugar substitutes are found in a variety of food and
beverages marketed as sugar free or diet including soft drinks, chewing gum,
jellies, baked goods, candy, fruit juice and ice-cream and yoghurt. [Whitney

People may not all like
the same kind of baked treats but one thing we all agree on is that baked
treats should be sweets usually, sugar is used to lend sweetness to foods but
would cake taste just as good if the baker used a sugar substitutes instead of
sugar? Many people prefer not to use sugar often due to health reasons and
instead depend on sugar substitutes to sweeten their foods. But are sugar
substitutes the same as sugar? What exactly are the differences between sugar
and sugar substitutes?
Sugar also known as
sucrose comes from plants like sugar cane and sugar beets and is a
carbohydrate. Sugar adds bulk to cakes, cookies and all kinds of treats; sugar
also causes browning and caramelizing in foods when it is heated
as when cookies turn golden brown in the oven sugar is a natural substance,
something that our bodies can use for energy.
Sugar substitutes come
in three categories; artificial sweeteners, sugar alcohols and natural
sweeteners. Artificialsweeteners are attractive because they add almost no
calories to foods and are sometimes a part of weight loss programs. Also they
donot increase blood sugar levels which mean that diabetics can use them. Many
artificial sweeteners like sucralose were discovered by accident in the
laboratory. In 1976, a scientist in England was studying different compounds
made from sugar. The scientist asked a student to test the compounds but
instead the student tested them. Another category of sugar substitutes is sugar
alcohols. Sugar alcohols are not alcoholic beverages they do not contain
ethanol which is found in alcoholic beverages. Sugar alcohols like sugar have
calories and energy but not asmuch as sugar. Sugar alcohols like artificial
sweeteners do not contribute to tooth decay and affect blood sugar levels
slowly so diabetics can use them. Although sugar alcohols like xylitol,
sorbitol and erythritol are manufactured products the sources are often
natural. The last category of sugar substitutes is called natural substitutes.
The categories include maple syrup, agave nectar and honey.
