Introduction

In most cases, it is safe to eat lotus root with a reddish core. When lotus root is cut or damaged, the polyphenolic compounds within are oxidized in air and form quinone compounds, which may cause the root to turn red—a normal natural phenomenon. If the core is merely red, without any changes in texture and without unpleasant odor, it is generally still safe for consumption.

Generally speaking, it is safe to eat lotus root with a reddish core. Here's a detailed explanation:

When lotus root is cut or damaged, the polyphenolic compounds within react with oxygen in the air and oxidize into quinone compounds, which may cause the flesh to turn red. This is a normal natural phenomenon. If the core of the lotus root is merely red without any change in texture and does not have an unpleasant odor, it is generally still safe to consume. However, if the redness is accompanied by off-odors, softening, rotting, or other signs of spoilage indicating microbial contamination, it should not be eaten to avoid gastrointestinal discomfort.

When purchasing lotus root, choose fresh ones with smooth skin, no damage, and no unusual smell. Avoid those with black spots, soft or mushy areas, or foul odors to ensure food safety. Additionally, it is recommended to use stainless steel or ceramic cookware when preparing lotus root, as using iron pots may cause the lotus root to darken, affecting its appearance and palatability.
