Some strawberries are naturally white on the inside, and this is nothing to worry about. In other cases, it may indicate that the strawberry has been picked too early and has not yet finished ripening inside. Both should be safe to eat, but be wary of strawberries with white mold.

Why are my strawberries all white in the middle?
What Causes White Shoulders in Strawberries? – White shoulders in strawberries are caused by temperature fluctuations during the growing season. Either excessively cold or hot temperatures can play a role. These temperature changes prohibit the strawberries from being able to ripen properly.
When strawberries ripen, they ripen from the tip up to the stem, so the white shoulders are an indicator of that. To give you an example of a recent clamshell that I bought (at the time of writing this, it’s the end of February 2021), the strawberries were huge and there were a lot of white shoulders.
On some of the strawberries, it was close to 50% of the berry, which was particularly attention grabbing. These strawberries were grown in Oxnard, California and I even called the company to confirm that it was due to the weather. The temperature has been low in Oxnard lately and the berries were extra large because they had left them on the plant longer to try to get them to color up, but the berries had other plans!
Should strawberries be red or white inside?
Bigger, Blander, Blegh: Why Are Strawberries Worse? Melissa Block talks with Marvin Pritts, a Cornell horticulture professor, about why store-bought strawberries aren’t as tasty as the ones you might pick on your own. MELISSA BLOCK, HOST: I bet you know this feeling: you bring home a box of perfect, plump, ruby-red strawberries from the supermarket, then you bite into one and you taste absolutely nothing.
- Close your eyes and you might not even know it’s a strawberry at all.
- Why? Why? We’re hoping Marvin Pritts can help explain.
- He’s a horticulture professor at Cornell University and a berry crop specialist.
- Professor Pritts, welcome to the program.
- MARVIN PRITTS: Thank you.
- It’s good to be here.
- BLOCK: And how did this happen? The mass produced strawberry tastes nothing like a fresh strawberry that I might pick from a field.
What has that strawberry been bred to do? PRITTS: So over the last hundred or so years, people have been breeding strawberries for various important traits; size and yield – those are obvious ones, maybe color, disease and insect resistance, flavor. And as you select and try to improve one, oftentimes one of the others has to be sacrificed slightly to make progress.
So we’ve actually done work where we’ve taken strawberries from each the decades, for the last hundred years, and planted them in a common field and then evaluated them and see what has changed. And we’ve seen that size has increased. We’ve seen that yield has increased. We’ve seen that firmness has increased.
But we’ve seen that sugar content and flavor has somewhat decreased. BLOCK: You know, one thing I always wonder about, when I see those perfect strawberries in the supermarket, is the color. Is that actually sun-ripened redness just great from the field or is there something chemically-induced going on there? PRITTS: There is nothing chemically-induced.
- But a strawberry that’s not quite fully red will turn red even just sitting on the shelf.
- And that’s why the color is sometimes deceiving – it doesn’t necessarily mean that it’s fully ripe and fully flavorful.
- It’s too bad that supermarkets don’t let you sample before you buy, because that would really change the whole complexion of our supermarkets.
So we have to make judgments based on what we see and it’s not always reflective of how something tastes. If you could slice the strawberry in half, too, that could tell you a lot. Usually the better flavored strawberries are red through and through. A lot of the strawberries that aren’t quite so flavorful are white – they’re red on the outside but white on the inside.
- BLOCK: One thing you mentioned earlier was size, that we like bigger strawberries.
- Why the focus on larger fruit? Why has that become so dominant, do you think? PRITTS: I think for two reasons.
- One is Americans just naturally think bigger is better.
- Then the other factor, particularly with smaller size fruit like strawberries, is because of the labor situation being so expensive and difficult to obtain.
It’s a lot faster to pick a flat of strawberries when the strawberries are large, then it is when the strawberries are small. Large strawberries saves you a lot of money and labor. BLOCK: Marvin Pritts, when you’re buying a strawberry, what do you look for? PRITTS: The first thing I do is look for where they are grown.
- But I don’t want strawberries that are so right that they start to decompose or mold or get watery inside the package.
- BLOCK: And then you just cross your fingers and hope that they taste like something.
- (SOUNDBITE OF LAUGHTER)
PRITTS: That’s right. And, you know, the breeders don’t intentionally select for strawberries that don’t taste good. It’s just that it’s hard to have that flavor and everything. So, sometimes they hit a homerun and end up with something that’s really high yielding and productive, and tastes really great, too. But a lot of times they don’t quite get there.
- BLOCK: Well, Marvin Pritts, thanks so much for talking to us.
- PRITTS: You’re quite welcome, Melissa.
- BLOCK: Marvin Pritts is a horticulture professor and a berry crop specialist at Cornell University.

Is white on strawberry OK?
Is it OK to eat moldy strawberries? – If you find white fluffy stuff on your berries that looks a bit like cotton candy, that is mold. Mold is a fungus with spores that feed on the berries and grow thin threads that can look like fluff or cotton. This particular type of mold is common among fruits and is known as Botrytis fruit rot or gray mold,
While moldy strawberries are unlikely to harm you, they can make you sick if you are allergic to molds in general, according to the USDA, And since berries are a soft-fleshed food, unlike apples or pears, it is not safe to simply cut away the moldy part, since the spores have likely gone into the flesh of the berry.
If a berry is bruised, but does not show any signs of mold, the bruised part can be trimmed away. A moldy strawberry should be thrown out. If you happen to accidentally eat a moldy strawberry, you’ll know it because, usually, moldy strawberries will have an off flavor that is a bit sour and acidic and may remind you of blue cheese.
The off taste is nature’s red flag that your red berries are bad, if you missed the visual mold. A small amount of this mold is unlikely to make you sick. If you ate a larger amount, you might have some signs of gastric distress similar to mild food poisoning, but it should resolve on its own, and is not toxic or especially dangerous, just uncomfortable.

What color should the inside of strawberries be?
Every week we get Down & Dirty, in which Nozlee Samadzadeh breaks down our favorite seasonal fruits, vegetables, and more by the numbers. Strawberries are nuts! Actually, they’re fruit – and despite the name, they’re not berries. Whether you’re eating them plain or with clotted cream, stacking them sky-high with meringues, or using them to top a spinach salad, here’s everything you need to know about buying, storing, and eating everyone’s favorite all-American fruit (literally – the Pilgrims had them at the first Thanksgiving)that’s versatile, delicious, and as good for snacking as it is for sherbet, ricotta, or roasting, 1. Seedy business : Let’s get technical: the reason that a strawberry is not, in fact, a berry is because true berries have their seeds on the inside. According to the California Strawberry Commission, there are on average 200 seeds on every strawberry! Depending on the variety, they can appear as either raised or sunken yellow dots on the surface.
- They’re perfectly edible, and birds like them too – this farmer describes having birds swoop in to eat the seeds off of his strawberries without even breaking the fruit’s skin! 2.
- Color Theory: As America’s Test Kitchen tells us, the strawberries that you see at the store may be red – they continue to ripen in color after being picked – but it doesn’t mean that they’re sweet.
The USDA found that strawberries picked early and ripened off the plant were only 72% as good in flavor as those harvested from the plant! Strawberries come in all shades, from orange-red to much darker, all depending on the variety, the weather, and the soil.3. 4. Vivid Vivisection: When you bite into a strawberry, you should see uniform red on the inside. Strawberries that are white inside – or worse, hollow – don’t last as long because of the air space of oxygen inside the fruit that speeds decay. According to the USDA, berries with “less air space and less oxygen inside.keep their color and flavor better than most varieties.” 5. Leaf Cap: The leaves on a strawberry are edible, but you probably don’t want them in your pie or ice cream. Use a spoon to easily scoop away, or “hull,” the top of the plant.6. See Spot Run: Strawberries are often sold in tiny baskets called “punnets.” (Cool name, huh?)If you see red splotches on the punnets of strawberries you’re buying at market, it’s a good sign that some of the fruit may be too ripe and has been crushed under its own weight. I’m Nozlee Samadzadeh, a writer, editor, farmer, developer, and passionate home cook. Growing up Iranian in Oklahoma, working on a small-scale organic farm, and cooking on a budget all influence the way I cook – herbed rice dishes, chicken fried steak, heirloom tomato salad, and simple poached eggs all make appearances on my bright blue kitchen table.
Are strawberries supposed to be hollow in the middle?
2. Selecting the Sweetest Berries – Strawberries continue to ripen off the vine—so the ones you see at the store may look red and juicy, but it could be the case that they’re totally lackluster. (Strawberries that sweeten on the vine are much fuller in flavor.) The color can be deceiving as well, since different varieties of strawberries come in varying shades of red.
And bigger isn’t always better—strawberries are often more concentrated in flavor when they’re tiny. And, as a general rule of thumb, the more fragrant the fruit is when you buy it, the better it will taste. When you slice one open, be wary of strawberries that are mostly white inside—or worse, hollow.
The more space there is inside for air to circulate, the faster the berries will grow moldy and rot. Those with less air space retain their flavor and color much better.
What kind of strawberries are white inside?
Varieties of White Strawberries – There are multiple varieties of white strawberries. The three most common are:
Fragaria vesca, also known as Alpine Strawberries. These are native to Europe and have names like Pineapple Crush, White Delight, and White Giant. Fragaria chiloensis, also known as Beach, Coastal, or South American Strawberries. These true white strawberries are native to Chile. Fragaria chiloensis x virginiana, also known as Pineberries. This hybrid white strawberry was first developed in South America and made its way to France, where it has been very popular. Pineberries turn a slight pink hue in the sun because they do have a small quantity of Fra a1.
Other varieties of white strawberries include Keoki, which is a Fragaria x ananassa hybrid like Pineberries, but it lacks the pineapple flavor; and Snow White. Pineberries and Keoki are both hybrid white strawberries, so they cannot be grown from seed like Alpine and Beach Strawberries.
What are the signs of good quality in strawberries?
California strawberries are fully ripe at the time they are picked and do not continue to ripen after harvesting. Here are a few tips on how to select & how to store strawberries to make your berries last as long as possible.
Choose berries that have a bright red color, a natural shine and fresh looking green caps.Strawberries should always be refrigerated and kept dry until just before serving.With green stems still intact, rinse berries under cool water.After rinsing, gently blot dry.Remove the green caps from the berries with a light twist or with the point of a knife.
Ideas on How to Eat Strawberries Fresh California strawberries are most flavorful at room temperature. They can be enjoyed just as they are or sliced in cereals, salads and served with any meal, any time of day. For additional ways to serve strawberries, check out our recipe pages, our blog, or the California Strawberries Facebook page.

Media Platforms Design Team Strawberry season is in full swing so now is the perfect time to incorporate this flavorful fruit into your dessert and drink recipes. This sweet berry is packed with nutrients and vitamins including fiber, potassium and vitamins B and C.
- When picking your next pint of strawberries, make sure to follow these tips on how to choose, store and prep your berries.
- You will have your family and friends begging for more of these berry tasty treats.
- Choose berries that are shiny, firm and fragrant.
- Believe it or not, size doesn’t affect flavor, but they don’t ripen after they’re picked, so choose the ripest ones you can find.
They should be a rich red with bright green leafy caps. Don’t be thrown off by white “shoulders”—some varieties are naturally white in the center and around the cap, even when ripe. Store berries in the refrigerator, since they’re highly perishable. Keep them in their plastic containers or, if they’re justpicked, in a shallow bowl, loosely covered with plastic wrap, unwashed and with caps on, until you’re ready to use them (maximum 3 to 4 days).
- Toss any moldy berries immediately—mold spreads quickly.
- Prep just before using: Rinse berries with caps still attached under a gentle spray of cool water, then pat dry with paper towels.
- To remove the caps, give them a gentle twist, use a paring knife to cut off the stem end or use a strawberry huller.
For best flavor, let them come to room temperature.
Are overripe strawberries safe to eat?
Signs of Overripe Strawberries – When it comes to strawberries, it’s important to know when they are overripe. Overripe strawberries can still be safe to eat, but they may not taste as good and could potentially cause stomach upset. Here are some signs to look out for to determine if your strawberries are overripe:
Mushy texture: Overripe strawberries will often have a mushy texture that is not pleasant to eat. If your strawberries feel soft and squishy, they may be overripe. Leaking juice: As strawberries become overripe, they may start to leak juice. If you notice any juice or liquid pooling at the bottom of your container of strawberries, they may be overripe. Shrivelling: Overripe strawberries may also start to shrivel up and become wrinkled. If your strawberries have lost their plumpness and look shrivelled, they may be overripe. Mould: Mould is a clear sign that your strawberries are no longer safe to eat. If you notice any mould growing on your strawberries, it’s best to throw them away.
It’s worth noting that some softness and juiciness is normal for ripe strawberries. However, if your strawberries are excessively soft or leaking juice, they may be overripe. If you’re not sure if your strawberries are overripe, you can also try smelling them.
Do strawberries need to be red?
Have You Ever Wondered. –
Are all strawberries red? Where are white strawberries grown? What makes some strawberries white?
Let’s play a quick game of answer as fast as you can. What do you sleep in? A bed! If you’re not alive, you’re what? Dead! What color is a strawberry ? Red! That last question was actually a trick question. If you answered red, you’re like most people.
- But aren’t all strawberries red? Nope! Some strawberries are white.
- And, no, we’re not talking about the unripe strawberries that change from small green berries to larger white berries that eventually turn red when they’re ripe,
- There are actually several varieties of white strawberries that ripen and never turn red.
Two of the most common varieties of white strawberries are white subspecies of Fragaria vesca (also known as the Alpine strawberry) and Fragaria chiloensis (also known as the Beach, Coastal, Chilean, or South American strawberries). They are grown in many areas and can be found in some stores or ordered online direct from nurseries that grow them.
While white strawberries from the true species Fragaria vesca and Fragaria chiloensis will grow true from seed, other varieties of white strawberries are the result of hybrids. For example, pineberries are a Fragaria x ananassa hybrid that result in a white strawberry with a taste that some believe is a mixture between strawberry and pineapple.
Another white strawberry hybrid is the rare White Jewel (also known as Shiroi Houseki ) created recently by Yasuhito Teshima from Japan. The result of years of cross-breeding varieties under special low-light conditions, the White Jewel is larger and whiter than other specialty breeds of white strawberries in Japan.
Want to try a White Jewel? It’s going to cost you! They sell for about $10 each and can be found in department stores rather than grocery stores. They’re usually bought by the Japanese as special gifts rather than a sweet treat to eat at home. So what makes white strawberries white? The answer lies in what they lack.
Regular red strawberries make use of a special ripening protein called Fragaria allergen A1 (or Fra a1) to turn from white to red when they ripen. White strawberries contain very little to no Fra a1, which means they ripen but stay white. The protein they lack is also the protein primarily responsible for strawberry allergies,
As a result, some individuals with strawberry allergies can eat white strawberries without any problems. If you like to garden, growing white strawberries in containers may interest you. Although white strawberry plants tend to produce fewer and smaller berries compared to regular strawberry plants, the berries they do produce can have especially sweet flavors.
As an added bonus, you might not have to worry about birds pillaging your berries. Most birds tend to ignore white strawberries because they don’t turn red, which usually signals when they’re ripe and ready to eat!
Can you eat discolored strawberries?
If the majority of the fruit is ‘squishy’, extremely discolored, has a foul odor, or the skin is wrinkling or peeling away with the slightest touch, the fruit is should most likely not be eaten. Berries often spoil quickly and are fairly delicate, although usually are completely fine for consumption.
Are organic strawberries white inside?
It is the larger firm hybrids that lean toward the white, hollow interiors because these were bred for colossal size and a firmness to enable shipping. And yet the organically grown tend to be smaller and, yep, red in the interior.
Is white mold bad for you?
Is White Mold Dangerous? – Make no mistake, white mold has its health risks, but it’s just as dangerous as any other color of mold. Continued exposure to any kind of mold can pose a serious threat to your health with symptoms including headaches, nausea, dizziness, allergies, and respiratory infections.
Anyone with asthma is at additional risk for white mold symptoms. In more serious cases, mold exposure can cause long-term issues like memory loss and depression. The more time you spend around mold, the greater the risk that you will suffer negative health effects. So, it’s important to take care of any white mold as soon as you see it.
White mold also presents a more indirect threat: compromising the structural integrity of your building. It is common to find white mold on wood in homes. The mold survives by eating away at the surfaces it’s on such as support beams or other essential components of a property.
What’s in the middle of a strawberry?
Fruit, Not Seeds – The “true fruits” of the strawberry are what we think of as the seeds. Technically, those small, yellow seed-like bits are called achenes, and each is a fruit. Inside each achene is the actual strawberry seed. An average-sized strawberry holds about 200 achenes. The Spruce / Jayme Burrows
What is the Colour of raw strawberry?
Strawberry fruit has a red color because it is rich in anthocyanins.
What color is a strawberry when it’s ripe?
When the strawberry is ripe? – Strawberry is a very particular fruit because often its appearance deceives. Usually the unripe strawberries are green, then during the ripening process they turn white and finally red. But it is also possible to find unripe red strawberries: why? This happens because, when a big strawberry is collected, it stops ripening, despite the red color, characteristic of the fruit, continues to intensify.
So to understand if a strawberry is ripe we must not only look at the color, but pay attention to its scent: in fact, if the strawberry has its characteristic scent means that it is ripe, otherwise it is not. If at the time of purchase, organic strawberries are white or pale pink it means that they have not been harvested at the right time because they are not yet ripe.
Be careful, however, with too much red strawberries: if they have a dark color it means they are old and could be harmful to our health. Once you understand how to know when the fruit is ripe, it’s time to learn about the benefits of strawberry on our body.

The garden strawberry (or simply strawberry ; Fragaria × ananassa ) is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness.
It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of Fragaria virginiana from eastern North America and Fragaria chiloensis, which was brought from Chile by Amédée-François Frézier in 1714.
Cultivars of Fragaria × ananassa have replaced, in commercial production, the woodland strawberry ( Fragaria vesca ), which was the first strawberry species cultivated in the early 17th century. From a botanical point of view, the strawberry is not a berry but an aggregate accessory fruit, meaning that the fleshy part is derived not from the plant’s ovaries but from the receptacle that holds the ovaries,
