Can you eat brown guacamole?

In this short article, we will answer the question, “Can you eat brown guacamole?” with an in-depth analysis of brown guacamole, ways to keep guacamole from turning brown and extend the shelf life of guacamole, nutritional value and health benefits of guacamole. 

Can you eat brown guacamole?

Yes, you can eat brown guacamole. It is completely safe to consume as long as you store it in the refrigerator and use it within a few days. Guacamole turns brown because of oxidation when exposed to air. The brown colour is a symbol that the guacamole is not freshly prepared. It may be slightly mushier and bitter than green guacamole, but it is absolutely safe to eat. 

Why does guacamole turn brown?

A chemical reaction takes place between oxygen and enzymes that lead to browning. Enzymes cause fruits to mature, but when these enzymes interact with the oxygen they produce a brown pigment called melanin. 

This is a natural process that can eventually lead to spoilage by the growth of microorganisms. When bacteria and moulds start to grow, it is not safe to consume guacamole and should be avoided. 

However, you can separate the top brown layer to expose green and fresh guacamole beneath or you can mix it all together. The top brown layer of guacamole is common when storing it in the refrigerator overnight. The brown guacamole has a somewhat bitter taste.

If your guacamole has turned dark brown or black, check first by smelling it and observing for symptoms of mould. By checking the smell of guacamole we can have an idea if it is still safe to eat. 

How to keep guacamole from turning brown?

There are a few methods for extending the shelf life of guacamoles and preventing them from turning brown so soon. One of the best approaches to store it is to hinder the oxidation process caused by enzymes. For this, you need to restrict the exposure of guacamole to air. This can be achieved by using:

Lemon or Lime Juice:

If you want to keep your guacamole for later use, before storing the guacamole, spray some lemon juice on top. Even out the surface using the rear side of a spoon so that there are no bulges and wrap a sheet of plastic directly against the guacamole. 

Then wrap the entire container firmly with extra plastic wrap to prevent the exposure of oxygen to your preparation.

The citric acid in lemon juice has antimicrobial qualities that help prevent the growth of microorganisms. Citric acid and ascorbic acid contain antioxidants that decrease additional ripening. 

It is an easy approach to increase the shelf life of guacamole while being out in the open space for several hours. However, this method does not go well for storing guacamole overnight. Plus, do not overdo it as it might change the flavour of guacamole. 


Similar to the juice method, water is also used before storing the guacamole. The idea is to keep a layer of water over the guacamole. The water stops the exposure of guacamole to air. For this purpose, completely submerged the guacamole in a bit of water. 

This method works the longest at retaining the green and fresh guacamole and does not alter the flavour. Just make sure the water is filtered and not local tap water.

Nutritional value of guacamole

The nutritional breakdown of ¼ cup serving of guacamole is as follows:

  • Calories: 109
  • Fat: 10 g

Guacamole possesses an abundance of beneficial fats, but as they are still fats they can quickly become a high-calorie food if excessively consumed. Moreover, some guacamole recipes are also prepared with excess amounts of salt and can be an unreliable source of sodium.

Health benefits of eating guacamole

Guacamole is enriched with nutrients so it provides remarkable health benefits. It contains monounsaturated fats that are good for heart health and fibres that are good for a healthy gut.

Guacamole contains a good amount of potassium that is an essential nutrient for regulating blood pressure and balancing the fluids in our body. It also prevents bloating.

Guacamole has lower amounts of calories than many other sauces, and dips, making it a healthier choice to eat. However, some guacamole sauces may consist of mayonnaise or buttermilk, which can add undesired fats and calories. If you are not certain, it is better to confirm the ingredients.
