Cantaloupe: A Nutritious and Delicious Fruit With Health Benefits
A Popular and Tasty Melon
Cantaloupes are the most popular melon in the United States. Their beautiful orange flesh has a sweet and delicious taste and a fragrant aroma. They are nutritious fruits that contain a wide variety of beneficial vitamins and minerals. They are a great melon to eat on their own or to use in fruit salads, smoothies, or desserts.
Cantaloupes are sometimes known as rockmelons or muskmelons. The outer rind or skin of the fruit is a buff or pale orange color. It's covered with ridges arranged in a mesh pattern, which produces a distinctive appearance. The ridged and indented surface is often said to have a netted or webbed pattern. The indentations mean that there is an important precaution that needs to be taken when preparing a cantaloupe for a meal. The outer rind can trap harmful bacteria and should be washed carefully before it’s cut.
The scientific name of cantaloupes is Cucumis melo. This is the same scientific name of most melons and squashes, which are all close relatives of each other. The European cantaloupe and North American cantaloupe are different varieties of melon. The European variety is referred to as the “true” cantaloupe and has a smooth rind.
The origin of the name "cantaloupe" is unknown. The leading theory is that the plant is named after Cantaluppi or Cantalupo, a papal estate that once existed near Rome. This estate is traditionally thought to have been the first European site to cultivate the plant. Africa, Iran, and India have all been suggested as the place where cantaloupes originated.
Cleaning the Rind to Prevent Foodborne Illness
Both Salmonella and Listeria bacteria may be present on the rind of a cantaloupe. These organisms can cause foodborne illness. Before a cantaloupe is cut, the rind should be scrubbed with a hard brush. The brush should be cleaned afterwards so that it doesn’t contaminate other food. If an uncleaned rind is cut with a knife, bacteria may be transported to the flesh of the fruit, contaminating it.
The fruit should be eaten soon after cutting so that any bacteria on the flesh have only a short time to multiply. Cut cantaloupe must be kept in the refrigerator in a covered container and should be eaten within three days.
How to Peel and Cut a Cantaloupe
Beta-Carotene and Vitamin C
Cantaloupes are rich in beta-carotene, which our bodies change into vitamin A. Vitamin A is needed to keep our eyes and skin healthy and our immune systems working efficiently.
Cantaloupes are also an excellent source of vitamin C. Vitamin C helps to maintain healthy skin and gums, stimulates wound healing, enables the body to make the collagen found in muscles and skin, and helps iron to be absorbed in the small intestine. It may also improve the functioning of the immune system, although evidence for this is mixed.
Vitamins A and C are antioxidants. These are substances that neutralize chemicals called free radicals, preventing them from damaging our DNA. Free radicals are produced by chemical reactions in our body. A high concentration of the chemicals in the body may contribute to the development of certain diseases. Some researchers theorize that free radicals also contribute to the aging process.
Clinical trials in which people have taken antioxidant supplements have had very mixed results, with some trials showing no benefit with respect to a health problem—or even harm from taking the supplements—while others have shown benefits. However, plenty of research has shown that eating whole fruits and vegetables containing natural antioxidants and many other helpful substances is beneficial.

Some Other Nutrients in the Fruit
Cantaloupes are also rich in potassium. Potassium is an essential mineral for muscle contraction and the heartbeat. In addition, cantaloupes provide smaller but useful amounts of other vitamins and minerals, including folate, vitamin B6, vitamin K, and magnesium.
A ripe cantaloupe contains a lot of fructose, which gives it sweetness. Unlike sucrose (table sugar), fructose doesn't increase the blood sugar level dramatically. It is a type of sugar, however, and shouldn't be eaten in excess. If you use very ripe cantaloupe in your recipes you probably won't have to add any other sweetener to them.
Using the Seeds
The center of a cantaloupe contains a cavity in which the seeds and fibers are located. Both the seeds and the fibers are safe to eat. However, make sure that you use seeds taken from a cantaloupe that you have cut open. Don't eat seeds from a seed packet or seeds that have germinated, which may not be safe, depending on what treatments the seeds have had.
The raw seeds are hard and aren't very tasty. Roasting the seeds with vegetable oil and spices improves the texture and produces a delicious taste. You may have to save washed and dried cantaloupe seeds in a refrigerator until you have enough to roast. The seeds can be cooked in oil in a frying pan until they turn light brown. They need about ten minutes in the pan.
Some people use both the cantaloupe fruit and the raw seeds to make a milk by placing them in a blender with water and then filtering the mixture after blending. The seeds reportedly contain protein and fat as well as some carbohydrate.
Using Cantaloupe Safely
Choosing a Fruit
When you're buying a cantaloupe in a store, choose one that feels heavy for its size. There should be no bruises, dents, green areas, or soft spots. The fruit should have a pleasant aroma. You may be able to buy cantaloupe at any time of the year, but the summer ones are more likely to have been grown nearby and will taste sweeter.
It's certainly not necessary to avoid buying cantaloupes because of the fear of bacterial contamination. The taste of a ripe cantaloupe is too good to miss. It is a good idea to wash the fruit before using it, though.
How to Grow Cantaloupes (Mini Variety)
Planting the Seeds and Growing the Fruit
I love cantaloupes, but I've never grown any. People with experience growing cantaloupes say that the freshly picked, homegrown fruit is tastier than store bought fruit. In a suitable climate it doesn't seem to be too difficult to grow the plants. They need sunlight, heat, and a good water supply that doesn't saturate the soil. Growers say that when the fruits are ready to pick they detach from their stems easily, almost slipping off the stems on their own.
Cantaloupe seeds are sometimes planted in mounds or hills to allow excess water to drain away from the plants. The usual recommendation is to plant five or six seeds about two inches apart and about one inch deep in each mound. The mounds should be four to six inches apart. The seedlings will need to be thinned once they've germinated. The plants grow well next to a trellis.
The seeds can be planted in pots indoors and then transplanted outdoors once they have germinated. It's very important that the roots aren't disturbed as the seedlings are placed in their permanent home.
It's recommended that cantaloupe seeds aren't planted until the soil temperature has reached at least 70°F. In temperate climates with a short growing season, the soil can be covered with black plastic to warm it up, as long as there are holes cut in the plastic.
Recognizing Salmonella Food Poisoning
Cantaloupes are occasionally recalled due to the presence of bacteria, such as Salmonella, which can cause foodborne illness. Listeria may also be a contaminant on cantaloupes, but Salmonella seems to be a more frequent problem. The bacteria are located on the rind but can easily be spread to the flesh once the cantaloupe is opened. The most common species of Salmonella involved in food poisoning is Salmonella enteritidis.
Symptoms of a salmonella infection include stomach pain, nausea, vomiting, diarrhea, headache, muscle pain, fever, and chills. The symptoms appear after an incubation period, which ranges from 8 to 48 hours after infection. The unpleasant effects of the infection generally last for 2 to 5 days but may last as long as 2 weeks.
Salmonella bacteria generally live in the digestive tract of humans. Bacteria may be shed in the feces for months after a person has apparently recovered from the infection. Animals can develop salmonella infections, too. Most infections in humans are caused by eating food contaminated by animal feces. This food includes meats as well as fruits and vegetables. Food hygiene is very important when using raw meat in a kitchen. Fortunately, Salmonella bacteria are killed by cooking.
Treating a Salmonella Infection
The immune systems of healthy people are usually able to destroy Salmonella bacteria, resulting in relatively mild infection symptoms which may require no treatment apart from drinking lots of fluids. If symptoms are severe or last for a long time, however, a doctor should be consulted. Young children, elderly people, and people with weak immune systems may become seriously ill from a salmonella infection and require hospitalization.
It's important for everyone—even those people who aren't in a high risk group—to wash cantaloupes before cutting them. If you do this you'll have safe access to the delicious and nutritious flesh of the cantaloupe as well as its useful seeds.
