How to tell if an avocado is rotten? 

The following parameters can tell you if the avocado is rotten or not.

Mushy texture

Avocado should yield slightly to the gentle press of your palms. If it does not give even a little bit, it is underripe. If it has mushy spots all over, it has started to rot.

Blackened rind

Ripe avocados should appear dark green or brown. If they start to turn black, they have started to rot. This is only applicable for Hass avocados. Avocado varieties like Zutano and Fuerte stay green even if they are fully ripe.

Dark and stringy flesh

If the avocado has black or brown spots or dark streaks in its flesh, it is rotten. If the flesh is fibrous but appears and tastes fine, it may not necessarily be rotten. Similarly, an avocado that comes from young trees has dark streaks, therefore, dark streaks or fibrous flesh alone is not a sure sign of spoilage.

Off flavor or odor

If the avocado gives off a sour or rancid smell instead of fruit and nutty odor, it is spoiled. The rancidity occurs due to the oxidation of the unsaturated fats present in the fruit. Rancidity results in the production of potentially dangerous compounds, therefore, never consume a rancid avocado.
