Study Notes

Processing Stages of Confectionery Items

Hard-boiled sweets, fondants, fudge, toffees, and jellies undergo key processing stages: mixing, boiling, cooling, beating, and shaping.
The boiling process uses three main methods: simple open boiling pan, steam jacketed pan, and vacuum cooker.
Steam jacketed pans enhance heat distribution and minimize localized overheating; vacuum cookers are suited for large-scale operations.

Cooling and Beating Processes

Cooling is essential before shaping; the boiled mass is transferred to a clean, crack-free metal, stone, or marble table for uniform cooling.
Sufficient cooling prevents burns during manual shaping.
Beating helps control crystallization, producing small crystals; in fudge production, the cooled mass is beaten after surface cooling.

Forming and Setting Techniques

Sweets can be formed by cutting into pieces or setting in molds; mold materials range from rubber, plastic, metal, to wood.
Gelling agents and stabilizers (e.g., gelatin, pectin, xanthan gum) provide binding and strength in confectionery.

Use of Colors and Flavors

Since most confectionery lacks natural color, artificial colors are added for flavor perception and differentiation.
Flavors include natural, essential oils, and artificial varieties, often incorporated at high temperatures due to their volatility.

Production Principles

Variety in confectionery products arises from differing ingredients, boiling methods, and shaping techniques while adhering to core principles:
- Balancing recipes
- Preparing and mixing ingredients
- Boiling to desired temperature
- Cooling, shaping, and packing

Factors Influencing Production and Storage

Key factors include sucrose inversion, boiling time and temperature, residual moisture levels, and inclusion of other ingredients like fats and milk powder.
High sugar concentrations can lead to undesired crystallization, known as graining, though it is acceptable for fondants and fudge.

Raw Materials and Ingredients

Main ingredients in sugar confectionery include sucrose, glucose syrups, fats, and various stabilizers, thickeners, emulsifiers, colors, and flavors.
Fats must melt around 37°C to avoid greasiness; cocoa butter is ideal, while lauric fats and partially hydrogenated oils are commonly used.
Emulsifiers like lecithin and glycerol monostearate aid in fat incorporation, with lecithin favored for hard-boiled sweets and glycerol monostearate for toffees and caramels.

Role of Milk Products

Milk components such as milk powder and condensed milk enhance flavor, nutrition, and color through Maillard reactions and caramelization.
