How To Tell If Grapefruit Is Bad?

Knowing how to tell if grapefruit is bad is important to ensure you’re enjoying the freshest and safest fruit.

To make sure you’re consuming the freshest and safest fruit, it’s important to follow the proper steps to evaluate the freshness of a grapefruit.

How It looks

To tell if grapefruit is bad by the way it looks take a look at the skin. The skin of a bad grapefruit may be dark and dull with brown spots, while ripe grapefruit has a vibrant, consistent color.

Look for water-soaked areas at the stem end of the fruit as this may indicate leaking juice. Additionally, fuzzy, whitish, or grey-green mold may form on the skin or a foul odor may be present, which indicates the fruit has gone bad.

How It Feels

To tell if grapefruit is bad by the way it feels, pick it up and evaluate its color, plumpness, and shape. Push gently with your thumb on the grapefruit’s skin and feel for any mushiness.

Remove your thumb and notice whether the skin bounces back to its original position. Bad grapefruit easily yields to pressure and takes longer to return to its original shape.

If any of these criteria are met, then the grapefruit has likely gone bad.

How It Smells

A bad grapefruit will have a distinct, unpleasant odor. It may smell damp or like rotten fruit.

If you notice a smell different than the normal aroma of a grapefruit, this is a warning sign that the grapefruit has gone bad and should be discarded.

How It Tastes

A bad grapefruit will not have the same sweet, tart taste it normally has. Instead, the texture will be soft and slimy.

If you noticed that your grapefruit, has mold, is really soft, or smells bad then do not try and taste it. Just throw it out and get another one.
