What is Organoleptic Testing?
Organoleptic testing involves using our senses—sight, touch, taste, and smell—to evaluate the quality of a product.
For filled bonbons, this means assessing their appearance, texture, flavour, and aroma over time to determine how long they stay at their peak.
Why is Shelf Life Testing Important?
The shelf life of filled bonbons is crucial not just for food safety, but also for ensuring that each piece delivers the delightful experience you intend.
Proper testing helps in:
- Maintaining consistent quality
- Reducing waste by better managing stock
- Ensuring customer satisfaction
- Complying with food safety regulations
Step-by-Step Guide to Organoleptic Shelf Life Testing
1. Preparation
Select a Sample Size:
Choose samples from different batches and production dates to get a comprehensive understanding.
Storage Conditions:
Store the bonbons under various conditions such as room temperature (around 20°C), refrigerated (4-8°C), and frozen (-18°C) to see how they fare in different environments.
2. Initial Assessment
Document Initial Quality:
Record the initial sensory qualities—appearance, texture, flavour, and aroma—using a detailed score sheet.
Photograph the Bonbons:
Take high-quality photos to document the initial appearance.
3. Regular Testing Intervals
Set Testing Intervals:
Determine regular intervals for testing (e.g., weekly, bi-weekly, or monthly).
Conduct Sensory Evaluation:
Evaluate the bonbons at each interval using the same criteria and score sheet. A consistent panel of trained testers is ideal, but including untrained consumers can also provide valuable insights.
4. Sensory Attributes to Monitor
Appearance:
Monitor changes in colour, gloss, and any signs of bloom. Note any deformation or cracking of the shell.
Texture:
Assess the firmness and mouthfeel of both the chocolate and the filling.
Flavour:
Check for changes in flavour intensity and balance. Detect any off-flavours that may indicate spoilage.
Aroma:
Evaluate any changes or development of undesirable odours.
5. Additional Testing
Microbiological Testing:
Conduct tests to check for mould, yeast, or bacteria, especially for bonbons stored at room temperature.
Physical and Chemical Analysis:
Measure moisture content, water activity, and other relevant properties to understand how they change over time.
6. Data Analysis
Compile Results:
Gather all the data from the sensory evaluations, photographs, and additional tests.
Identify Trends:
Analyse the data to find trends and determine when the bonbons no longer meet quality standards.
Determine Shelf Life:
Establish a conservative shelf life based on the results. This should ensure the bonbons are consistently high-quality for consumers.
7. Reporting
Prepare a Report:
Document the testing process, results, and conclusions in a detailed report. Include storage and handling recommendations.
Review and Update:
Regularly review and update the shelf life based on ongoing production and any changes in formulation or ingredients.
Conclusion
Conducting an organoleptic shelf life test may seem intricate, but it’s a vital process in ensuring that our filled bonbons remain as delightful as the day they were crafted. By meticulously monitoring their sensory qualities over time, we can provide our customers with the consistently excellent chocolates they expect and deserve.
