Carbohydrates as Sweeteners • Ability to sweeten is a major function in most foods. • The sweeter the sugar is, the simpler the structure of the molecule is. “Just a spoonful of sugar helps the medicine go downIn a most delightful way”
Carbohydrates as Preservatives • Helps prevent food spoilage of fruit jellies and preserves • Helps products such as cakes remain moist.
Carbohydrates as Tenderizers • Sugar added to dough makes the product tender Example: Cakes, pastries & doughnuts are more tender than Italian bread which contains no sugar • Absorbs water • Inhibits flour gluten development
Carbohydrates as Crystallizing Agents • In candies, sugar crystallizes. This function is linked to solubility. • Candy makers know the optimum temperature for making each type of candy. • Usually, the finer the sugar crystals are, the higher the quality of the candy.
Carbohydrates as Caramelizing Agents • Caramelization is the process of removal of water from a sugar (such as sucrose or glucose). • When sugar is subjected to high or prolonged heat, it changes into a brown liquid.
Carbohydrates as Fermenting Agents • Plays a major role in the fermentation process in the production of yeast breads, beers and wines. • Sugar acts a food supply for microorganisms such as yeast.
