Does Kiwi Go Bad? How Long Does It Last?

by Editorial Staff | Updated on October 1st, 2023

The longevity of kiwifruits is contingent upon several factors including their ripeness upon purchase and the conditions where they’re stored. For unripe kiwis, the ripening process unfolds gradually at room temperature, typically spanning between two days to a week. This duration, however, is not set in stone and may fluctuate depending on the storage conditions at the supermarket prior to purchase. Once the kiwi reaches its ripe state, it can be savored for several days if kept at room temperature, provided it’s stored in isolation. For prolonged enjoyment, a ripe kiwi can be refrigerated, where it can last up to an impressive four weeks. This extended lifespan within the chilly confines of a refrigerator offers ample time for consumption before the onset of spoilage.

How Long Can Kiwis Survive Outside?

Freshly purchased kiwis can sustain their freshness and edibility for up to six days without refrigeration. This duration, however, is subject to their ripeness at the time of purchase and the specific storage environment. Since kiwifruits continue to ripen after being harvested, an unripe kiwi might take up to a week to fully mature. In scenarios where the kiwi is significantly unripe at the time of purchase, it could feasibly remain fresh for over two weeks before showing signs of rot. Learning to manipulate the ripening process—either accelerating it for quicker maturity or decelerating it to extend the life of a ripe kiwi—is crucial in optimizing the fruit’s lifespan.

How Long Will Kiwis Last in the Fridge?

Refrigeration significantly extends the shelf life of kiwifruits by slowing down the intrinsic aging and ripening processes. A kiwi stored in the refrigerator can remain fresh for up to four weeks, allowing for prolonged enjoyment of the fruit. While this is beneficial for ripe kiwis, it can inadvertently hinder the maturation of unripe ones, resulting in fruits that are hard, unpalatable, and texturally unpleasant. Therefore, it’s advisable to refrigerate only those kiwis that have already reached maturity. Always assess the ripeness of your kiwis meticulously before deciding to refrigerate them to avoid premature spoilage.

How Long Will Kiwis Last in the Freezer?

Freezing offers a long-term storage solution for kiwifruits, with properly stored kiwis remaining edible for up to a year. However, without proper storage, kiwis can deteriorate within days, mirroring the shelf life they would have in a pantry. The intense cold within the freezer not only halts the aging process but can also inadvertently damage the fruit, leading to quicker spoilage. Consequently, it is of paramount importance to freeze only ripe kiwis. Moreover, whole unripe kiwis are particularly susceptible to damage from the extreme cold, leading to rapid deterioration and spoilage.

Refrigerating Overripe Kiwis: Does it Help?

Refrigeration is not a cure-all for preserving kiwifruits, especially if they are already overripe. Once a kiwi passes its prime, refrigerating it might slow down further deterioration, but it won’t reverse existing damage. If you find yourself with an overripe kiwi, it’s wise to consume it immediately, granted it’s still safe to eat, or reluctantly discard it if it has crossed into the realm of inedibility.

Kiwi Refrigeration Necessity: When and Why

Deciding whether to refrigerate kiwifruits? It largely depends on their ripeness and your consumption plans. Ripe kiwis should be refrigerated to halt the ripening process, especially if you don’t plan to consume them immediately. Since kiwis will continue to mature at room temperature or in warmer environments, promptly refrigerating ripe ones prevents them from becoming overripe, preserving their delightful taste and texture for your eventual enjoyment.

Signs of a Bad Kiwi: What to Look For

To determine if a kiwifruit has spoiled, apply the same vigilance you would with other fruits and vegetables. Key indicators include:

• Altered Texture: A kiwi that has become excessively soft, mushy, or has begun to leak should be discarded.
• Unpleasant Odor: If the fruit emits an acidic or off-putting smell rather than its typical fresh, citrusy scent, it’s time to let it go.
• Dark Spots: While minor discoloration on the skin might be harmless (as the skin is usually not consumed), dark spots on the pulp signal spoilage. If you’re comfortable, you might opt to remove the affected section and consume the rest, but doing so carries risks, and caution is advised.

Disease Susceptibility in Kiwifruits

Like all fruits, kiwifruits are susceptible to various diseases and pests. Environmental factors play a significant role in the plant’s health, with temperatures falling below -8 degrees Celsius impeding its growth. The pH level of the soil is crucial, with a range between 5.5 and 6.0 being ideal for robust kiwifruit vines; deviating from this range could lead to physical damage and reduced yield. Poorly draining soil can give rise to fungal infections like Armillaria root rot. Moreover, bacteria might infiltrate the vines and fruits, leading to conditions like Bacteria Blight, often resulting in accidental injuries to the vine.

Kiwifruit: An Overview

Originating from Southeast Asia, the kiwifruit is a distinctive brown, fuzzy fruit renowned for its sweet, vibrant green center rich in Vitamin C. Its interior is adorned with tiny, edible black seeds that contribute to its unique aesthetic and texture. While often enjoyed on its own, the kiwifruit is also a popular addition to jams, jellies, and fruit salads due to its striking color and delightful taste.

Health Benefits of Kiwi

The kiwifruit is not just a treat for the palate but also a powerhouse of nutrition. It’s loaded with vitamins and antioxidants that serve as a protective shield against cell damage caused by free radicals. The fruit’s high content of Vitamin C is not only a boon for the immune system but also offers potential benefits for asthma patients by improving lung function. Regular consumption of kiwi can aid in reducing blood pressure and minimizing the risk of blood clot formation. The fruit is also a source of zeaxanthin and lutein, compounds known for safeguarding the eyes from conditions like macular degeneration.

How to Select the Perfect Kiwi

The art of storing kiwis begins with the initial selection process. If a kiwi is nearing the end of its life when purchased, your options for prolonging its freshness are limited. For longer shelf life, opt for kiwis that are firm to the touch, indicating they are still in the ripening process. If you plan to buy in bulk, a majority of the kiwis should be somewhat unripe, allowing them to mature gradually at home. Nonetheless, ensure you pick a few ripe ones for immediate consumption. For those planning to eat the fruit immediately, choose kiwis that are slightly soft, signaling their ripeness. While the size of the kiwi doesn’t significantly impact its taste or quality, vigilant examination for any blemishes, soft spots, or signs of bruising is imperative. Avoid kiwis with wrinkles or signs of aging.

Determining Kiwi Ripeness

Unlike many fruits, kiwis have a more extended ripening period. Determining ripeness involves a tactile test: gently press the kiwi. If it’s hard, it is not ripe; if it has a slight give, similar to a ripe tomato, it is ripe and ready for consumption. Consuming an underripe kiwi will result in a tart and less pleasant flavor, so understanding the tactile signs of ripeness is crucial for an enjoyable eating experience.

Proper Kiwi Storage Practices

Understanding how to store kiwis properly is vital. Unripe kiwis are usually harvested to ensure they reach stores in optimal condition. An underripe kiwi is firm, and while it may seem inedible due to its hardness, it simply needs more time to ripen. For those looking to prolong the kiwi’s life, refrigeration is an option, but for those eager to eat their kiwis soon, leaving them at room temperature to ripen is advisable. To expedite the ripening process, place the kiwi in a vented plastic bag or container with ethylene-producing fruits like apples or bananas. Once ripe, kiwis can be stored either at room temperature or in the refrigerator, depending on when you plan to consume them. However, it is crucial to keep them away from direct sunlight and monitor those ripened with ethylene closely as these fruits can also hasten the deterioration of already ripe kiwis.

Freezing Kiwis: A Viable Option?

Freezing kiwis is indeed an option, but it’s crucial to acknowledge that the process will alter their texture. Though you can theoretically freeze kiwis indefinitely, their quality diminishes over time, so consuming them sooner is preferable.

Steps to Freeze Kiwis

• Preparation: Begin with ripe kiwis. Wash them thoroughly and let them dry.
• Peeling and Slicing: Peel the kiwis and slice them or scoop out their flesh, avoiding freezing them whole.
• Freezing Process: Arrange the kiwi pieces on a baking sheet lined with parchment paper in a single layer and place it in the freezer.
• Storage: Once frozen, transfer the kiwis to airtight freezer bags to prevent them from sticking together.

Pros and Cons of Freezing

While freezing extends the life of the kiwi, it comes with drawbacks. Thawed kiwis acquire a mushy texture, limiting their use to blended dishes like smoothies. The process is also time-consuming, necessitating thawing, which requires planning ahead.

The Implications of Freezing Kiwis

When opting for freezing as a method to extend the shelf life of kiwis, it’s crucial to consider its implications on the quality and application of the fruit in meals.

• Texture Transformation: Frozen and then thawed kiwis will have a mushy consistency. This change in texture narrows down their culinary applications. Primarily, they would be suitable for use in recipes where the texture isn’t a crucial factor, like smoothies or blended beverages.
• Time-Consumption: While dishes that incorporate kiwis, especially smoothies, are best served cold, some amount of thawing is necessary to facilitate easier blending without overtaxing your kitchen appliances. It’s important to note that thawing takes time, and you might need to start your food preparation earlier than usual to accommodate this step.

Conclusion

Kiwis are not only a tasty treat but also a health-boosting fruit that deserves a spot in your regular diet. Knowing how to properly select, store, and identify the ripeness or spoilage of kiwis enhances your experience with this exotic fruit. Whether you prefer your kiwis fresh, refrigerated, or even frozen for extended preservation, understanding their characteristics at each stage of ripeness and storage conditions ensures you get to enjoy their optimum flavor and nutritional benefits. With this guide, you’re now equipped to make informed decisions that will help you enjoy kiwis to the fullest while minimizing waste.
