Purple broccoli is safe to eat and may be sweeter

news.yahoo.co.jp (Japanese)

Purple-tinged broccoli is safe to eat and may even be sweeter. This color change is due to anthocyanins, a protective compound. The purple hue indicates the broccoli is developing anthocyanins, a natural response to cold temperatures. This indicates it is safe and potentially tastier. However, avoid broccoli that is black, slimy, or has open, yellowing florets, as these signs suggest spoilage or that the optimal eating period has passed.
