Understanding Best Before Dates
As Hong Kong's pioneering social enterprise, FlashGreen gives near-expiry products a 'second life'. Learn how proper understanding of best before dates can help reduce waste while ensuring food safety.
Best Before Dates: Quality, Not Safety
According to the Hong Kong Centre for Food Safety, 'Best Before' dates indicate when a product is at its peak quality. After this date, foods are often still safe to consume - they may just experience slight changes in flavor, texture, or nutritional value. Understanding this difference is key to reducing food waste.
