Quince is best described as a cross between apples and pears. However, this bright yellow fruit is healthier than them! Unlike apples and pears, raw quince tastes tart and sour. It is extremely popular and used in processed juices, jams, and spirits. This fall fruit is loaded with powerful antioxidants and is rich in vitamin C and dietary fiber. Keep reading to learn why you should add quince to your diet, ways to eat it, side effects, and recipes.

What Is Quince Fruit And Its History?

Quince (Cydonia oblonga) is a shrub or small tree belonging to the Asian genera and Rosaceae family. This yellow, pear-shaped hairy fruit has a typical flavor and aroma. Raw quince is tough, astringent, and sour.

This plant originated in Asia Minor and spread through the countries bordering the Himalayan mountains to the East and throughout Europe to the West. However, it is most likely that quince did not reach the Mediterranean region until the classical period when it was used by the Romans (1).

The ancient civilizations cultivated quince its medicinal benefits. Continue reading to discover what gives this fruit its medicinal powers.

Compared to apples, quince contains nearly two times more vitamin C and more minerals (3).

Shena Jaramillo, RD, says, “Quince fruit is a great source of potassium and fiber. Potassium is an important electrolyte in the body, and fiber aids in digestion. It is also a great source of vitamin C, which helps with collagen formation and supports the immune system.” Read on to learn more about the health benefits of quince.

7 Potential Health Benefits of Quince Fruit

1. A Good Source Of Antioxidants

Quince pulp, seeds, and peel are rich in antioxidant phenolic compounds because of their rich vitamin C (ascorbic acid) content (4). The phenolic compounds are crucial for minimizing oxidative stress and inflammation, the main causes of numerous health issues. Moreover, antioxidants also strengthen the immune system to protect the body against harmful pathogens.

2. May Protect Against Stomach Ulcers

A rat study found that the phenolic compounds in Chinese quince extracts could suppress gastric ulcers and keep the gastrointestinal tract healthy (5). The antioxidants can minimize inflammation and oxidative stress that might damage the mucous membrane in the stomach (gastric mucosa).

3. Antimicrobial Effects

The phenolic compounds in quince extract (pulp ad peel) have antimicrobial properties. They can disrupt bacterial cell membranes and interfere with their metabolism and eliminate them (6).

4. May Help With Pregnancy-Induced Nausea

A trial on pregnant women with mild to moderate nausea and vomiting (NVP) found that quince syrup could significantly reduce the symptoms. Quince is a safe fruit for pregnant women and maybe a better alternative therapy for improving nausea and vomiting (7).

5. May Have Anti-Allergic Effects

A mice study found that quince extract could relieve the symptoms of type I allergy (immediate reaction). It suppressed antibody production to inhibit the atopic dermatitis-like allergic responses (8).

6. May Help With Gastroesophageal Reflux Disease (GERD)

Research showed that quince fruit extract is as effective as ranitidine in relieving the symptoms of pregnancy-related GERD. Quince is traditionally used as a gastric tonic to boost gut health and reduce nausea, vomiting, and other gut-related issues (9).

7. May Prevent Cancer

A study observed that the phenolic compounds in quince fruit and leaf extracts inhibited the proliferation of colon and renal cancer cells. Researchers concluded that quince extracts might be useful in the prevention and treatment of cancer (10). However, more studies are required to prove the efficacy of quince extract as a chemopreventive and chemotherapeutic agent.

There are many ways to include quince in your diet. However, if you are new to this fruit, your tastebuds may take time to adapt to its rich, unassuming, and exciting flavor and texture. Take hints from the following sections to enjoy this delectable fruit.

How To Eat Quince Fruit

Quince can be eaten raw and cooked, with or without the skin. However, not everyone may prefer raw quince as it has a sour and astringent taste. Cooked quince has a sweet and floral flavor.

The best way to preserve (and consume) quince is by preparing marmalades, jams, and jellies. You may substitute quince for apples and pears in different recipes like crumbles, cakes, pies, and other desserts. You may also prepare quince vinegar (just like homemade apple cider vinegar) and enjoy this seasonal produce throughout the year. Here are a few popular recipes you may try.

Since quince is available during the fall, you may want to store it for later use. Here are a few tips.

How To Store Quince Fruit

Nadia Charif, RD, says, “Usually sold unripe in the US, it’ll take a few days on the countertop to ripen your quince. You’ll know it’s unripe if the fruit is more green than yellow, hard (rather than giving to the touch) & has little to no fruity fragrance. Like other fruits, to speed the process, store in a paper bag on the countertop.”

She adds, “Once cut, your quince will oxidize, so wrap tightly with plastic wrap or cover the cut portion of fruit thoroughly with lemon juice (albeit, this will make your quince more tart). Quince tends to absorb the odor of other foods, so it’s important to store away from strong smells whether on the countertop or in the refrigerator.”

According to Jaramillo, quince fruit can be stored for up to two weeks at cool temperatures.

Quince is a healthy and nutritious addition to your diet. However, it has several side effects.

Possible Side Effects Of Quince Fruit

Dr. Kire Stojkovski, MD, shares, “When consumed in large quantities, quince causes negative effects on the stomach (elicits the stomach to produce volatile gases). When exposed to the skin, the fruit causes irritations to the skin. It also causes inflammation (swellings). The fruit is also responsible for causing diarrhea and problems in digestion.”

The Final Word

Quince has been a part of ancient traditional medicine and is preferred by different ethnic groups for medicinal benefits. This nutrient-dense fruit is a rich source of antioxidants and helps minimize inflammation and oxidative stress. You can eat it raw or cooked. However, consume it in moderation as excessive quince intake may upset the stomach.

Frequently Asked Questions

Is quince good for diabetes?

Yes. Animal studies showed that quince lowered blood sugar levels in diabetic rats (11).

Does quince help with weight loss?

Yes. Quince is low in calories and high in dietary fiber and other nutrients. Dietary fiber promotes satiety, which may help you in portion control.

Do you have to peel quince before cooking?

Not necessarily. Quince peel is edible and contains antioxidants.

Why does quince turn red?

Cooked quince release a red pigment called anthocyanin (released from the tannins in the fruit). As a result, quince fruit with high tannin content turns dark rose, while those with low tannin content may remain creamy white or turn light pink.

How long does quince paste last?

Quince can be refrigerated for up to three months or longer under plastic wrap.
