Comprehensive Study Notes on Food Product Development, Safety, and Sustainability
Internal Factors Affecting Food Product Development
Internal factors refer to elements within a business or company’s control that impact the food product development process. These include:
Finance: The available budget and financial resources for a project.
Human Resources: The skills, knowledge, and number of employees available to the company.
Production Facilities and Equipment: The machinery and physical infrastructure available to manufacture products.
Research and Development (R&D): The internal capacity to innovate and design new food items.
Company Objectives: The specific goals of the organization, such as increasing profits, expanding a product range, or entering new markets.
Staff Expertise: Specialized knowledge and skills in areas like marketing and production.
Quality Control in Food Production
Quality control is a system designed to ensure that raw materials meet the manufacturer’s specifications before they enter the production line.
Incoming raw materials are rigorously tested for several characteristics:
Sensory: Appearance, taste, and texture.
Physical: Size and dimensions.
Chemical: levels and moisture content.
Biological: Microbial limits to prevent contamination.
Supplier Investigation: Suppliers are vetted to ensure they can provide consistent quantities of quality materials.
Outcome of Testing: Materials that fail to meet specifications are either rejected, returned to the supplier, or disposed of.
Benefits of Quality Control: These strategies prevent contamination, maintain product quality, and reduce waste and financial losses.
HACCP: Hazard Analysis Critical Control Point
HACCP is a food safety and quality assurance system that identifies potential food hazards and controls them at critical points throughout the food production process.
The seven steps of HACCP are:
1. Assess the Hazards: Identify potential biological, chemical, or physical hazards that could occur during food development, such as microbial contamination.
2. Identify Critical Control Points (CCPs): Pinpoint stages where a hazard can be prevented, controlled, or disappeared, such as temperature control or cooking.
3. Establish Critical Limits: Set specific safety boundaries, such as a minimum cooking temperature.
4. Establish a Monitoring System: Regularly check and record that critical limits are being met. An example is recording the temperature of a refrigerator at regular intervals.
5. Establish Corrective Actions: Determine what to do if a critical limit is exceeded, such as discarding unsafe food or recooking.
6. Verify the HACCP System: Conduct checks to ensure the system is working effectively; the system should be reviewed and updated regularly.
7. Set Up Records: Maintain monitoring results and documentation for accountability and safety audits.
Product Range Expansion: Line Extensions
Line extensions involve expanding the range of an existing product by introducing a new variation. Common changes include alterations to flavour, size, appearance, nutritional content, or packaging.
Examples:
Mars bars (variations in size or ingredients).
Coca-Cola (e.g., Vanilla Coke).
Advantages of Line Extensions:
Provides consumers with more choice.
Attracts new customers.
Increases sales and profits.
Considered low risk because the company can use an established brand, existing production equipment, and benefit from consumer brand loyalty.
Disadvantages of Line Extensions:
If the new brand is unsuccessful, it might damage the reputation of the parent brand.
Food Manufacturing and Processing Technology
Manufacturing technology involves using production systems, equipment, and processing techniques to transform raw materials into safe, high-quality food products.
Core Processes:
Separation: Removing specific components from a mixture using methods such as sieving or filtration.
Size Reduction: Making food smaller through cutting, slicing, dicing, or grinding.
Cooling: Using freezers to lower temperatures to slow down microbial growth.
Pasteurization: Heating food to kill microorganisms while maintaining product quality.
High Temperature Short Time (HTST): A specific technology where food is heated to .
Food Preservation Processes
These processes are designed to extend the shelf life of food and maintain safety:
Pasteurization: Targeted heat treatment.
Freezing: Usually involves temperatures below to slow microbial activity.
Canning: Sealing food in airtight containers to prevent spoilage.
Drying/Dehydration: Removing moisture from food to reduce the water available for microorganism growth (e.g., dried fruit).
Ethics in Food Advertising and Promotion
Media Influence: Media strongly influences consumer food choices through traditional advertising and social media.
Ethical Responsibility: Food manufacturers and advertisers must provide truthful, accurate information. They must not exaggerate health benefits or hide disadvantages.
Vulnerable Audiences: Children are particularly vulnerable to food advertising, making responsible promotion essential.
Informed Decision Making: Consumers are encouraged to read nutrition labels and make informed decisions rather than relying solely on advertisements.
Nutritionally Modified Foods
Nutritionally modified foods are altered during manufacture to increase desirable nutrients or reduce/remove unwanted nutrients.
Fortified Foods: Nutrients are added to a product to increase their levels, such as adding iodine to salt.
Enriched Foods: Nutrients that were lost during processing are added back. An example is adding B vitamins and iron back into refined white flour.
Promotion of Good Health in Society
Government Organizations: The Australian Dietary Guidelines provide advice on what should be eaten to maintain health and reduce the risk of diet-related diseases such as obesity.
Community Groups: Organizations like Care Van and Meals on Wheels provide nutritious meals to individuals who struggle to cook for themselves, such as the elderly or those with disabilities.
Food Industry: Retailers like Woolworths promote good health by providing a range of healthier food options, including fresh fruit, vegetables, and products reduced in sugar and fat.
Private Agencies: Dietitians provide professional, personalized nutrition advice to help individuals develop healthy eating habits tailored to their specific needs.
Individuals: Individuals improve their own health by following dietary guidelines and maintaining healthy behaviors like regular physical activity and a balanced diet.
Food Packaging Systems and Materials
Packaging protects food from contamination, maintains quality, and facilitates transport.
Types of Packaging:
Primary Packaging: Comes into direct contact with the food (e.g., a wrapper around a muesli bar).
Secondary Packaging: Surrounds a group of primary packages to protect them and make them easier to handle or transport (e.g., a cardboard box containing six cupcakes in individual wrappers).
Tertiary Packaging: Used for bulk transport and distribution, allowing large quantities to be moved efficiently and safely (e.g., pallets or large shipping containers).
Main Packaging Materials:
Glass: Non-reactive (doesn't interact with food), easy to sterilize, and reusable. However, it can break easily and is often transparent, which could affect light-sensitive products.
Plastics: Lightweight, strong, durable, resistant to breaking, and inexpensive. A significant downside is that they are bad for the environment.
Paper and Cardboard: Cost-effective and lightweight.
Metal: Strong and durable, protects from physical damage, and provides a long shelf life. It is also recyclable.
Steel: Often used for canned solids or semi-solids like fruit and vegetables.
Aluminium: Primarily used for soft drink cans.
Warning signs: Metal cans that are heavy, dented, or bulging may indicate that the food inside is no longer safe.
Packaging Labeling Requirements
Mandatory information on food labels includes:
Ingredient List: A list of all ingredients in descending order by weight.
Use-by or Best-before Dates: Indicators of food safety and quality over time.
Nutrition Information: Details on energy, fat, sugar, and other nutrients.
Directions for Use and Storage: How to keep the food safe after opening.
Country of Origin: Where the food was grown, produced, and packaged.
Weight/Measure: The net contents of the package.
Ecologically Sustainable Production in Agriculture
Ecologically sustainable production methods minimize environmental damage and protect resources for future generations by reducing pollution and maintaining soil and water quality.
Organic Farming: Produces food without synthetic pesticides, herbicides, fertilizers, or growth hormones. It relies on natural methods to maintain soil fertility and control pests.
Crop Rotation: Growing different crops in a planned sequence to replenish soil nutrients and reduce the build-up of pests and diseases.
Conservative Farming Methods:
No-till farming: Reducing soil disturbance to prevent erosion.
Multispecies cover crops: Protecting soil and providing habitats for beneficial organisms.
Strip cropping and terrace cultivation: Methods used to manage water flow and prevent soil loss.
Biodiversity: Maintaining a variety of plants, animals, and microorganisms is crucial for healthy ecosystems, supporting pollinators, and reducing reliance on chemical pesticides.
Sustainable Fisheries and Aquaculture
Sustainable Fishing: Harvesting fish at a rate that allows populations to reproduce and remain healthy.
Management Strategies:
Catch limits and quotas: Restricting the total amount of fish caught.
Size limits: Requiring young fish to be released so they can mature and reproduce.
Fishing seasons and protected areas: Closing areas to fishing during breeding periods to allow populations to recover.
Selective equipment: Using gear designed to reduce bycatch (accidental capture of non-target species like turtles or dolphins).
Aquaculture: Farming aquatic animals (fish, shellfish, crustaceans) in controlled environments.
Benefits: Reduces pressure on wild populations and provides a reliable seafood supply.
Risks: Must be managed carefully to avoid environmental impacts from waste, disease, and escaped farmed species.
Emerging Technologies in Food Production
Sensors and Precision Agriculture: Uses GPS, satellites, and sensors to monitor soil, crops, and livestock in real time. This saves water and fertilizers, reduces costs, and improves productivity.
Automation and Robotics: Robots can plant, weed, harvest, and pick fruit. While this increases efficiency and reduces labor requirements, it can reduce employment opportunities.
AI in Retail: Automation and AI are used to predict demand for products, which helps manage stock levels. Retailers like Woolworths operate over 1000 stores in Australia and use technology like "scan and go" to improve the customer experience.
In-vitro (Cultured) Meat: Meat grown from animal cells in a lab rather than through slaughter. This could increase food supply and reduce environmental impacts, though it is currently expensive and faces uncertain consumer acceptance.
Vertical Farming: Growing crops in stacked layers indoors. This allows for year-round production and efficient use of space with less transportation, though it requires significant energy and expensive technology.
