Study Notes

Executive Summary

Date marking of foods is regulated by Standard 1.2.5 under the Australia New Zealand Food Standards Code.
Use by dates are required when food is the sole nutritional source or can become microbiologically unsafe before spoiling.
Best before dates apply when deterioration affects consumer acceptance without posing health risks.
Foods with a shelf life of two years or more do not require best before dates.
Reliable shelf life determination requires technical expertise and cannot rely on competitor products or guesswork.

When is Date Marking Required?

Use by dates are mandatory for foods that are health or safety sensitive.
Health reason applies to products like infant formula, where nutrient stability is critical.
Safety reason applies to foods that can become unsafe before visible spoilage, such as certain chilled ready-to-eat meals.
Best before dates are for products where deterioration affects consumer appeal but not safety.
Common factors affecting product acceptance include rancidity, texture changes, moisture fluctuations, and microbial spoilage.
Most foods typically need date marks, with notable exemptions being specific shelf-stable products.

How is Shelf Life Determined?

Shelf life determination involves assessing various deteriorative factors impacting products.
Accurate shelf life estimation requires advanced product development to ensure consistent production.
Critical factors include pH levels, water activity, and even distribution of ingredients.
Both physical and microbiological profiles must be established through rigorous testing of multiple product batches.

Product Stability and Food Safety

Initial storage trials should be conducted under recommended conditions, usually 5°C, including mild temperature abuse scenarios.
Regular inspections and tests check stability for critical physical and chemical characteristics during the storage trials.
Key concerns during trials:
- Changes in pH due to microbial activity
- Water redistribution and stability of the product
- Integrity of the preservative system
- Signs of microbial growth
- Chemical migration from packaging materials into food
Understanding critical characteristics and their acceptable ranges over intended shelf life is crucial for safety and quality.
