Kiwi is a nutrient-rich fruit that has gained popularity worldwide for its unique taste, vibrant green color, and numerous health benefits. While many people enjoy eating kiwi, there’s often a question about whether the skin is edible. In this article, we’ll delve into the world of kiwi, exploring the edibility of its skin, its nutritional value, and the benefits of consuming it.
What is Kiwi Skin Made Of?
Before we dive into the edibility of kiwi skin, let’s understand what it’s made of. Kiwi skin is composed of several layers, including:
The Exocarp
The outermost layer of the kiwi skin is called the exocarp. This layer is thin, smooth, and slightly waxy to the touch. The exocarp serves as a protective barrier against environmental factors, such as moisture loss, temperature fluctuations, and pathogens.
The Mesocarp
Beneath the exocarp lies the mesocarp, a thicker layer that’s rich in fiber and antioxidants. The mesocarp is responsible for the kiwi’s fuzzy texture and is also where you’ll find most of the fruit’s flavonoids and phenolic acids.
The Endocarp
The innermost layer of the kiwi skin is the endocarp, a thin, membranous layer that separates the skin from the fruit’s pulp. The endocarp is relatively soft and edible.
Is Kiwi Skin Edible?
Now that we’ve explored the composition of kiwi skin, let’s answer the question: is it edible? The short answer is yes, kiwi skin is edible. However, it’s essential to note that not all kiwi skins are created equal.
Factors Affecting Edibility
Several factors can affect the edibility of kiwi skin, including:
- Variety: Some kiwi varieties, like the Hayward kiwi, have thicker, fuzzier skins that may be less palatable than others.
- Ripeness: Unripe kiwis tend to have tougher, more bitter skins that may not be as edible as those of ripe kiwis.
- Growing conditions: Kiwis grown using conventional farming methods may have higher pesticide residues on their skins, making them less desirable for consumption.
- Handling and storage: Kiwis that are handled roughly or stored improperly may develop bruises or blemishes on their skins, which can affect their edibility.
Nutritional Value of Kiwi Skin
Kiwi skin is a rich source of nutrients, including:
- Fiber: Kiwi skin is high in dietary fiber, containing both soluble and insoluble fiber.
- Antioxidants: The skin of kiwis is rich in antioxidants, including flavonoids, phenolic acids, and ascorbic acid.
- Vitamins and minerals: Kiwi skin is a good source of vitamins C and E, as well as minerals like potassium and magnesium.

How do I prepare kiwi skin for eating?
Preparing kiwi skin for eating is relatively simple. Start by washing the kiwi under running water, then gently scrub the skin with a vegetable brush to remove any dirt particles. Next, slice or chop the kiwi, skin and all, and add it to your desired recipe. You can also peel the kiwi and use the skin separately, such as adding it to a smoothie or using it as a garnish for salads or desserts.
When using kiwi skin in recipes, keep in mind that it can be quite tart, so you may want to balance the flavor with sweeter ingredients.

When eating kiwi skin raw, be sure to choose organic kiwis with thinner, more palatable skins. Conventionally grown kiwis may have thicker, waxier skins that are less pleasant to eat raw. Also, be aware that some people may experience a slight tingling sensation on their tongue or lips when eating raw kiwi skin, due to the high concentration of actinidain, a proteolytic enzyme.
Is kiwi skin safe for everyone to eat?
While kiwi skin is generally considered safe to eat, there are some individuals who may need to exercise caution. People with sensitive stomachs or digestive issues may find that eating kiwi skin exacerbates their symptoms, due to its high fiber and enzyme content. Additionally, individuals with allergies or intolerances to kiwi or other fruits in the Actinidiaceae family should avoid eating kiwi skin.
Pregnant or breastfeeding women, as well as young children, should also consult with their healthcare provider before consuming kiwi skin, as its high vitamin C content may interact with certain medications or exacerbate underlying health conditions. As with any new food, it’s essential to introduce kiwi skin in moderation and monitor your body’s response.
Can I use kiwi skin in cooking and baking?
Yes, kiwi skin can be used in a variety of cooked and baked recipes, adding a burst of flavor and nutrition to your dishes.

In baking, kiwi skin can be used to make delicious muffins, cakes, and breads. Simply chop the kiwi skin and add it to your favorite recipe, or use it as a topping for muffins or scones. Kiwi skin can also be used to make jams, preserves, and chutneys, adding a tangy flavor and crunchy texture to your homemade condiments.
How do I store kiwi skin to maintain its nutritional value?
To maintain the nutritional value of kiwi skin, it’s essential to store it properly. If you’re not using the kiwi skin immediately, you can store it in an airtight container in the refrigerator for up to 24 hours. Make sure to keep the container away from strong-smelling foods, as kiwi skin can absorb odors easily.
For longer-term storage, you can freeze kiwi skin, either whole, sliced, or chopped. Simply place the kiwi skin in an airtight container or freezer bag, making sure to remove as much air as possible before sealing. Frozen kiwi skin can be used in smoothies, baked goods, or as a topping for yogurt or oatmeal. When freezing, be aware that the texture of the kiwi skin may become softer and more prone to browning.
