How to preserve Avocado

In this brief article, we will answer ‘’How to preserve avocado’’. This article will also discuss how to use preserved avocados,  their shelf life, and the use  in cooking. Avocados are a good source of healthy lipids, such as unsaturated fatty acids, vitamin B, C, E and K fiber, which makes it a good option for a diet with lower carbohydrate contents (7).

How to preserve avocados?

There are several ways to preserve avocados to keep them fresh for longer:  

  • Refrigerate them In general, unripe avocados should be stored at 5 to 12 ºC (41 to 54 ºF) (1). 
  • Freeze them: Cut the avocados in half, remove the pit, and scoop out the flesh. Place the avocado halves or mashed avocado in a ziplock bag, remove as much air as possible, and freeze for up to 6 months. Frozen avocados are perfect for making smoothies, guacamole, and other recipes (2).
  • Pickling: This is a tasty way to preserve them. Cut avocados into slices and place them in a jar with vinegar, water, sugar, and spices. Refrigerate for at least 24 hours before serving. Pickled avocados are perfect for sandwiches, salads, and tacos (2).
  • Dehydrate them: Dehydrating avocados is a great way to preserve them for longer periods. Cut the avocados into thin slices and place them on a dehydrator tray. Dehydrate at 135°F for 8-12 hours until they are completely dry and crispy. Store the dehydrated avocados in an airtight container for up to 6 months (3).
  • Make avocado oil: Avocado oil is a healthy and delicious oil that can be used for cooking and salad dressing. Cut avocados into chunks and mash them to a puree. Heat the avocado puree in a saucepan over low heat, stirring constantly until the oil separates from the pulp. Strain the oil and store it in a glass bottle (4).

By using one of these methods, you will be able to preserve avocados and enjoy them for longer.

What is the shelf life of an avocado?

The shelf life of avocados may vary depending on several factors, such as their maturity at the time of purchase, storage conditions, environmental factors, and mode of preservation. In general, the shelf life of avocados preserved in different ways is as follows:

  • The shelf life of ripe avocados is 3-4 days if stored in the refrigerator. 
  • Frozen avocado can last up to 6 months in the freezer. However, the texture and taste may change after several months.
  • Avocado oil can last approximately 6-12 months if stored properly in a cool, dark place. It is important to note that the half-life of avocado oil can be shortened if exposed to light and heat, which can cause it to oxidize and go rancid more quickly (4,5,6).

What factors affect avocado ripening?

Several factors affect avocado ripening, among them (1):

  • Temperature: avocados ripen best at room temperature, between 18-21°C (64-70°F). Higher temperatures can speed up the ripening process, while lower temperatures can slow it down.
  • Humidity: Avocados ripen best in a humid environment. High humidity helps prevent moisture loss, which can cause the fruit to dry out and become leathery.
  • Ethylene gas: Avocados are sensitive to ethylene gas, which can be produced by other fruits and vegetables. Exposure to ethylene gas can cause avocados to ripen faster than desired or become overripe.
  • Bruising: Like bananas, bruising and damage to the fruit can cause it to ripen faster and spoil more quickly.
  • Age: Avocados that are already ripe will continue to ripen and will eventually over ripen if not consumed or used.
  • Variety: Different avocado varieties have different ripening times and degrees of creaminess. For example, Hass avocados, which are the best-selling variety, ripen in 3-5 days at room temperature, while Bacon avocados take longer to ripen and have a less creamy texture.

By understanding these factors, you can properly store and manage your avocados to ensure that they ripen at the desired rate and are at their best when you are ready to eat them.

​​How to use avocados in cooking?
