What are Packed and Processed Biscuits?
Packed and Processed Biscuits are ready-to-eat baked products made from flour, sugar, butter, and other ingredients, designed to have a long shelf life. Biscuits come in a variety of forms, including sweet, savory, digestive, cream-filled, and whole wheat. Packed biscuits are convenient snacks enjoyed by consumers around the world due to their versatility, taste, and easy portability.
Producing biscuits requires a range of specialized equipment, including dough mixers to achieve the perfect consistency, dough sheeters and cutting machines to shape the biscuits uniformly, and rotary or tunnel ovens to bake them to the right texture and color. Cooling conveyors are used to cool biscuits before packaging while weighing and portioning machines ensure consistent sizes and weights. Filling and packaging machines seal the biscuits in airtight containers or wrappers, preserving their freshness and crunch. Quality control systems monitor moisture levels, texture, and flavor consistency throughout the production process to ensure every batch meets high-quality standards.
Types of Packed and Processed Biscuits
- Sweet Biscuits: Sugar-based biscuits, often flavored with vanilla, chocolate, or butter.
- Digestive Biscuits: Made with whole wheat flour and designed to be a healthier option, often served with tea.
- Cream-Filled Biscuits: Biscuits sandwiched with flavored cream fillings, such as chocolate, vanilla, or strawberry.
- Savory Biscuits: Salted biscuits, often flavored with herbs, spices, or cheese, offer a savory snack alternative.
- Multigrain or Whole Wheat Biscuits: Made from a blend of flours, including whole wheat and oats, for a healthier alternative.
Technical Processes for Packed and Processed Biscuits
1. Dough Preparation
- Ingredient Mixing: Ingredients like flour, sugar, butter, and leavening agents are mixed in high-speed dough mixers to form a homogeneous dough. Additives like chocolate chips, nuts, or dried fruits can be incorporated at this stage depending on the biscuit variety.
- Dough Resting: The mixed dough is allowed to rest to improve its elasticity and texture, making it easier to shape and bake. Resting times and conditions (temperature and humidity) are carefully controlled for consistency.
2. Shaping and Cutting
- Dough Sheeting and Cutting: The dough is passed through sheeting machines that roll it to the desired thickness, typically between 1-3 mm. Rotary cutters are then used to cut the dough into various shapes—round, square, or custom shapes, depending on the product.
- Extrusion (For Filled Biscuits): For cream-filled biscuits, the dough is extruded and formed into the base shape, with the cream being injected between the layers before the baking process.
3. Baking
- Baking Conditions: Biscuits are baked in tunnel ovens at temperatures ranging from 160-220°C, depending on the type of biscuit and desired texture. Baking time typically ranges from 10 to 20 minutes, during which the biscuits develop their characteristic texture and golden-brown color.
- Crispness and Texture: The moisture content of biscuits is reduced during baking to below 5%, ensuring a crisp texture and long shelf life. Proper baking times and temperatures are essential to prevent over-browning or under-cooking.
4. Post-Baking Treatments
- Cooling: After baking, biscuits are cooled in cooling tunnels or conveyor systems to bring them to ambient temperature. This step is crucial for setting the structure and ensuring the biscuits remain crisp.
- Cream Filling and Decoration: For cream-filled biscuits, the baked biscuit layers are cooled and then passed through filling machines that add a layer of flavored cream between the biscuits. Some biscuits may also receive chocolate enrobing or other decorative finishes after baking.
5. Packaging
- Portioning and Wrapping: After cooling, biscuits are portioned into individual or multi-serve packs using automated packaging machines. Moisture-proof, air-tight packaging is essential for preserving the crispness and freshness of the biscuits.
- Modified Atmosphere Packaging (MAP): For certain varieties, Modified Atmosphere Packaging (MAP) may be used to extend shelf life by displacing oxygen and preventing spoilage or staleness. This is particularly useful for cream-filled or chocolate-coated biscuits.
- Nitrogen Flushing: In nitrogen flushing, the air in the packaging is replaced with nitrogen to prevent oxidation and keep the biscuits fresh over extended periods.
Engineering of Packaging Materials for Packed and Processed Biscuits
1. Moisture-Proof Packaging
- Objective: Prevent moisture absorption and keep biscuits crisp.
- Materials: Multi-layer plastic films with excellent moisture barrier properties.
- Benefits: Moisture-proof packaging ensures that biscuits retain their crispness and flavor, even in humid conditions. This is essential for long shelf life, especially for export markets.
2. Modified Atmosphere Packaging (MAP)
- Objective: Extend the shelf life of biscuits by controlling the internal atmosphere of the packaging.
- Materials: High-barrier films, often used in combination with nitrogen flushing.
- Benefits: MAP helps preserve the freshness and texture of biscuits by reducing oxygen levels inside the package, which prevents staleness and spoilage.
3. Eco-Friendly Packaging Solutions
- Objective: Provide sustainable packaging options while ensuring product protection.
- Materials: Recyclable or biodegradable materials like paper-based pouches or compostable plastic films.
- Benefits: These eco-friendly packaging solutions reduce environmental impact while maintaining the quality and safety of the packaged biscuits.
