2. What happens when you heat a sugar solution? sugar Much sugar Super saturated water Sugar solution saturated

3. Supersaturation  Supersaturation is an unstable state.  The sugar molecules will begin to crystallize back into a solid at the least provocation.

5. Sugar Crystal Crystal form something like release locking together, except that instead of legos pieces, there a molecules. If some of the molecules are different size and shape, they won’t fit together and a crystal doesn’t form Crystal

6. Principles of Sugar Confectionery Production • Variation in ingredients used, temperature of boiling, and method of shaping  possible to make a wide variety of products. • Balance the recipe • Prepare the ingredients • Mix together the ingredients • Boil the mixture until the desired temperature has been reached • Cool • Shape • Pack

7. Principles of Sugar Confectionery Production • Many factors affect the production and storage of sweets: • The degree of sucrose inversion (see below) • The time and temperature of boiling • The residual moisture content in the confectionery • The addition of other ingredients.

8. Degree of Sucrose Inversion “The amount of invert sugar in the candy/sweets must be controlled!!!!” Tartar, citric acid  can be used in controlling amount of inversion If too much  sticky candy (take up water from the air). If too little  insufficient to prevent crystallization of the sucrose. Non-crystalline (Hard candy) 10-15% of invert sugar

9. Candy Thermometer A candy thermometer, also known as a sugar thermometer, is a thermometer used to measure the temperature and therefore the stage of a cooking sugar solution. These thermometers can also be used to measure hot oil for deep frying. There are several kinds of candy thermometers available  1)traditional liquid, 2)coil spring "dial“ and 3)digital. The digital thermometers tend to read the temperature more quickly and accurately, and some models have an alarm when the thermometer hits a certain temperature. Many models have markers for the various stages of sugar cooking. A candy thermometer is similar to a meat thermometer except that it can read higher temperatures (usually 400°F/200°C or more).

15. Sweet and Boiling Temperature

16. Moisture Content • The water left in the sweet will influence its storage behaviour and determine whether the product will dry out, or pick up, moisture. • For sweets which contain more than 4% moisture, it is likely that sucrose will crystallize on storage. • The surface of the sweet will absorb water, the sucrose solution will subsequently weaken, and crystallization will occur at the surface - later spreading throughout the sweet.

17. Added ingredients • The addition of certain ingredients can affect the temperature of boiling. •  For example, if liquid milk is used in the production of toffees, the moisture content of the mixture immediately increases •  Therefore require a longer boiling time in order to reach the desired moisture content. • Added ingredients also have an effect on the shelf-life of the sweet.  Toffees, caramels, and fudges, which contain milk-solids and fat, have a higher viscosity, which controls crystallization. •  On the other hand, the use of fats may make the sweet prone to rancidity, and consequently the shelf-life will be shortened.

18. Type of Candy Fondants • is made by boiling a sugar solution + glucose syrup. • The mixture is boiled to a temperature in the range of 116-121°C • cooled, and then beaten in order to control the crystallization process and reduce the size of the crystals. Creams / Crystalline • are fondants which have been diluted with a weak sugar solution or water. • These products are not very stable due to their high water content • have a shorter shelf-life than many other sugar confectionery products. • are commonly used as soft centres for chocolates and other sweets. Gelatin sweets • These sweets include gums, jellies, pastilles, and marshmallows. • They are distinct from other sweets as they have a rather spongy texture which is set by gelatin.

19. Type of Candy Toffee and caramels • These are made from sugar solutions with the addition of ingredients such as milk-solids and fats. • Toffees have a lower moisture content than caramels • consequently have a harder texture. • As the product does not need to be clear, it is possible to use unrefined sugar such as jaggery or gur, instead of white granular sugar. Hard-boiled sweets • These are made from a concentrated solution of sugar • heated and then cooled to form a solid mass containing less than 2% moisture. • Within this group of products there is a wide scope to create many different colours, flavours and shapes through the use of added flavourings and colourings.
