Food experts considered vegetables and fruits to be very difficult to store properly. This is because the amount of water in these products is very high, creating excellent conditions for microorganisms to function. Eggplant is no exception.
So, how long does eggplant last? Eggplant contains a high ratio of water (~85%) by weight overall. So, it is easy to spoil.
Generally, it would be best to use it no longer than 2 hours at room temperature and one week in the fridge with the proper packing method to keep the texture and taste.
How Long Does Eggplant Last
Preserving eggplant should have the right conditions. There are two most popular choices that are often use such as being refrigerated and stored at room temperature.
In The Fridge
As mentioned above, the water content in eggplant is very high, ranging from 85% – 95 by weight overall. So, it is easy to spoil after a short time. On the other hand, the nutritional composition of vegetables is mainly absorbed sugars, such as glucose, fructose, and polysaccharides.
The texture of most of these compounds is loose. Therefore, bacteria can easily absorb and grow. During the harvest and in-store display with other agriculture products such as chickpea substitute, the respiration, and physiology of the fresh eggplant also induces internal hydrolysis. This will cause microorganisms to grow faster.
So, how long does eggplant last in the fridge? The answer is for 5-7 days.
Refrigerating can maintain the correct temperature so that the eggplant won’t spoil for a long time. Like how to freeze chili, you should adjust the refrigerator temperature from about +2 to +6 degrees for the best eggplant shelf life.
The humidity during storage needs to be between 70 and 75% for the best results. These are ideal environmental conditions to inhibit the growth of harmful microorganisms and prevent them from multiplying.
However, some harmful bacteria have evolved and can survive even below 0 degrees Celsius. Therefore, if you want to keep it for 6-8 months, you should keep the brown eggplant in the freezer.
Another important thing is that you need to protect the greens from the sun’s rays. Otherwise, they will deteriorate in a few days and adversely affect human health. The fact is that under the action of ultraviolet rays in these vegetables, there is an increased solanine production. And in such amounts, it harms health, and the vegetable itself becomes unpalatable.
However, this vegetable is too susceptible to many types of rot, infecting each other, so where they will lie must be decontaminated. It is best to use ion filters in the refrigerator; they will be extremely effective for disinfection.
Besides, in a closed environment like a refrigerator, bacteria can easily move from one place to another. Just one spoiled eggplant will make all the other fruits spoiled. Therefore, prior to storing, you need to wipe off the surface of the eggplant. Take care not to use cold water for washing as the moisture, in this case, can only be harmful.
Before sending fruits for long-term storage, each one needs to be carefully examined so that the skin is not damaged and there are no inactivation points.
We recommend buying a slightly immature eggplant; you can recognize them by their skin – it’s thick and shiny, and has a bright purple color.
Before the vegetables are sent for storage, you should wipe each with a natural cotton cloth. We do not advise you to wash an eggplant before putting it in the fridge. The moisture, in this case, can bring harm only.
At Room Temperature
First of all, room temperature is not recommended when it comes to food preservation. It would help if you only left for a maximum of 2 hours on the kitchen counter, then cook immediately.
This is because this scent relies entirely on the eggplant’s resistance to disease and the durability of the eggplant when the ambient conditions do not have any supportive effects.
Eggplant, after being harvested, will continue with the same normal respiration as it did on the mother plant. All of its living activities are normal, including respiration.
The more intense this process occurs, the faster the ripening time will take place, and as a result, the eggplant will also rot very quickly.
At this time, the activity of microorganisms inside the food will be very strong. They will continuously multiply and affect the nutritional quality of eggplant. In addition to pre-existing bacteria, the atmosphere also helps introduce microorganisms into cracks in the fruit’s surface, causing more serious damage. These include both mold and infections.
How To Tell If Eggplant Has Gone Bad
Some people think that it is safe to store eggplant in refrigerator, but the fact is that even in the freezer, food can still be penetrated by bacteria. We should eat all of the food as quickly as possible. If not, the cabinet should note the following colors, flavors, and signs before use.
Bad eggplant usually has white, black, or green spots. This is a sign of mold growth. If you continue to eat them, you risk a stomach infection. Processing should be continued only when the eggplant has a smooth, shiny, uniform color. You can pay attention to the knob of the eggplant to determine the freshness.
Besides, the entire eggplant surface may have white or yellow bubbles, a sour smell like sour buttermilk. Many people often habitually remove the white cheeses or rinsing the bubbles and keep eating, but this is very not recommended.
Bacteria have sizes calculated in micrometers, so basically, your naked eyes can not see them. Therefore, bubbles tell us that these eggplants should be thrown away as it is already home to thousands of bacteria. This rotten eggplant can cause you severe diseases like diarrhea, stomach pain, or food poisoning if continued.
In addition to visual observation, you can check whether the eggplant still good or not by gently pressing your finger against the peel.
If eggplants are a bit hard, the color of the peel is around pink, purple, light purple; it is an old fruit and about to spoil. It would be best to eat them immediately. In the event that you notice unusual tenderness in certain areas, they may be rotting.
How to Store Eggplant For a Long Time
Store In The Fridge
This is so obvious, without any doubt, the best way on how to keep eggplant fresh.
You should avoid leaving the eggplant in tied plastic bags because it will spoil much more quickly. In addition, cooked eggplants are also very sensitive to ethylene, a natural gas that ripens fruit and leads to fruit rot.
So the best way to preserve plain eggplants is not to mix them with tomatoes, bananas, and watermelon, which are all ethylene-secreting fruits.
Use Airtight Container
Sealed containers or vacuum sealers help you reduce the penetration of air into the food and reduce oxidation. It helps keep the taste and quality of both raw and fried eggplant for longer, reducing the growth of bacteria.
However, keep in mind that there is no way to completely prevent spoilage. This method can also slow down the spoilage process when combining safe food storage at cold temperatures.
Therefore, you should use the product as quickly as possible after buying it! Eggplant lasagna or sauté ground beef with eggplant salad will be a great choice.
Make Eggplant Pickle
What about how to store cut eggplant?
For eggplant slices, soak it in warm water with a little salt, then rinse it to make the skin softer, not bruised, and remove the acrid taste. It would be best if you also eat the shell because it contains B vitamins and vitamin C, which are very healthy.
Knowing “how long does eggplant last” is very important to the health of you and your family. In addition, it is also essential to regularly check their status to promptly discard damaged frozen eggplant.
