Why Does My Watermelon Smell Rotten? Know The Fact!

Why Does My Watermelon Smell Rotten

The watermelon fruit has a distinctive smell that’s caused by the presence of ethylene gas. Ethylene is a plant hormone released during ripening and helps the fruit mature and become sweet.

However, as the fruit ripens, the concentration of ethylene increases until it becomes too much for our noses to handle. This triggers an odour-sensing protein called an olfactory receptor, which detects this unpleasant scent.

There are two types of rotting watermelon: internal and external. In the former, all that’s going wrong is inside the fruit, in which bacteria from rotten flesh infect or spread to other parts prompting decay.

The latter happens when an outer layer can’t keep up with the rate at which it decays, making larger portions misshapen and prone to agricultural ripening disorders like mildew or mould.

There is a solution. Just keep away from such watermelon and buy your reals melon, a delicious, not-too-big quality product that does its job with the greatest care for all of us. No more horrors to worry about when buying fresh fruit.

How to Understand Watermelon is Rotten or Not?

How to Understand Watermelon is Rotten or Not?

There are many ways to answer this question. One way is to look at the colour of the watermelon. If it is green, then it is not rotten yet. Another way would be by touching it and feeling if there are any soft spots on the watermelon.

If there are soft spots, then it is rotten already, and you should throw away the watermelon immediately.

The last way to know if the watermelon is rotten or not would be by checking certain substances that may occur on the fruit. These substances tend to add an undesirable colour and smell. One of these is cocci (or “coccoid”) bacteria which typically consist of large numbers and can cause decay quickly.

A few examples include Clostridium sporogenes, Bacillus cereus, Staphylococcus aureus, and Irgasys genus- especially if the fruit is not from perfectly chilled water or has been exposed to light.

Others are mold like species such as Aspergillus fumigatus, Penicillium nalglei and Saccaromyces cerevisiae which may be white in colour, meaning that these organisms have invaded the outer skin of fruits.

Some others might include Ent ranceococcus faecaledones and Lactobacillus species. These can cause spoilage due to rapid maturation of the flesh that ripens too quickly.

If a fruit has one or more of these kinds, you should not consume it until this situation is fixed to avoid any food poisoning issues.

In addition, if your watermelon still shows soft spots on its surface after several days (or weeks) later even some spores on the surface, then it is a sign that spoilage has probably occurred and you should discard it.
