1. What are the criteria to be considered when choosing a natural sweetener? Explain. Natural sweeteners should be selected by comparing their relative sweetness, flavor profiles, color contributions and functionalities. Each natural sweetener has a different composition of saccharides, and thus a different chemical structure, molecular weight, level of solubility and colligative properties. As such, sweeteners impact body and mouthfeel, viscosity, freezing and boiling points, crystal formation and inhibition, browning reactions, water activity, and hygroscopicity.

2. Why sucrose is considered as an ideal sweetener? Sucrose has a clean flavor and a smooth, level sweetening sensation. These products are less processed than white sugar, have a good consumer image and can be sourced from organic raw ingredients.

3. What are the components of soy lecithin? Soy lecithin is a complex mixture of phospholipids, glycolipids, triglycerides, sterols and small quantities of fatty acids, carbohydrates and sphingolipids.
