Most products are cookedHot waterAll you have to do is pour in (some products that use yakisoba or raw noodles require a hot water drain).The cup of this productkitchenwareAt the same timeTableware(It also plays the role of a package at the time of display). There are also many types that heat and cook in a microwave oven.

Noodle foods to be cupped include a wide variety of noodles, including oriental wheat noodles such as ramen and udon noodles, pasta (western wheat noodles), and rice noodles such as rice noodles and pho.in shortfreeze dryBy processing, it is possible to make any noodles into cup noodles[Annotation 1]Is.Nowadays, cup versions of foreign noodle foods are available in Japan as well.

Also, due to the dietary habits of the Western folk culture, some of the overseas market products have shorter noodle lengths than domestic products, due to the history of the origin of the main meal described below.


Ando Baifu 1971/(Showa46 years)May 9Released inCup NoodlesIs the first product (excluding pre-trial sales)[Annotation 2]). Nowadays it is also eaten as a staple food, but initiallySnackHas been developed with a view to popularization asWesternWhen I went to sell instant noodles, I didn't have a bowl for ramen, so I put it in a paper cup.Chicken RamenThe idea was to cut in, pour hot water and sample with a fork.

It is a remnant that cup noodles have a smaller noodle capacity (noodle weight 90-100g) than regular bag noodles (about 60-70g).the 1980sUntil the second half, other manufacturers followed suit,1988/(Showa 63)Ace cockStarted selling the "Super Cup" series, which declared the "Large size" with a noodle capacity of 90g, which is equivalent to bag noodles, and after this became a big hit, each company followed suit.Staple foodLarge-capacity products (generally noodle weights of 80g or more), which are intended to be popularized as noodles, will also play a part in the mainstream of cup noodles.Later, it was decided to manufacture "large size" cup noodles.On the other hand, Tokyo Ramen Co., Ltd. also sells individually wrapped noodles and mini-cup noodles, which are about half the normal size of mini-sized products (about 30g of noodles) for the L class (female customers and young people).

1972/ OfAsama Sanso IncidentAt the time ofriot policeOn the TV, a worker is eating cup noodles given as emergency food in the coldLive broadcastSince it was broadcasted frequently in Japan, cup noodles became known and spread throughout Japan.[3].

In the European and American markets,chopsticksAt the beginning of the launch of Cup Noodles, it was a foldable type because the culture of Cup Noodles had not penetrated.forkThe product accompanied by was also present in Japan. There are still foreign market products with forks similar to this attached. In addition, because of this, there was a time when the cup noodles were sold with a plastic fork attached instead of the disposable chopsticks when they were purchased.


The container is usuallyStyrofoamOrpaperIs used.Styrofoam is used because it has good heat retention and heat insulation properties and is not hot when held.In the case of a paper container, this point is overcome by making the outside of the container cardboard-shaped.A typical one is "Sapporo Ichiban Cup star'[4]Is.Recent ones have a stepless container just by making the cup a double structure.In recent years, some paper products, such as Styrofoam, have a space (existing in the Nisshin Cup Noodle series).Compared to paper containers, Styrofoam can make more diverse shapes, and the early ones are all Styrofoam, but NISSIN FOODSPatentBecause of the application, latecomers mainly made paper containers.AlsoTokushima millingSome products, such as "Kin-chan Ramen", use multi-layered non-foamed styrene case cups even for domestic products.There are also single-layer styrene cup products in foreign products.

Most dried noodle types have noodles directly in the container,Raw type noodleVacuum packed all that noodles包装After that, it is in a state of being put in a container.

The main container is usually disposed of, but it may be reused, for example, "Eating chicken ramen in a cup noodle container" (however, the structure cannot be used for a long period of time, so it is only for simple use.[Annotation 3]).

Usually, the seal is made of paper or similar on the top surface, and this part is finally removed from the main container after eating.This is not the case if the container is made of plastic and the lid is also made of plastic. In this case, the main body container can be reused together with the lid.This can be used to reuse the entire container for another food item, or for simple storage other than food items.[Annotation 3].

Due to the manufacturing process of the sealing film that seals the main body of the cup noodles, it is unavoidable that the sealing film is penetrated by the transport gear (sprocket) of the conveyor, and regular small holes may be observed.In some cases, there may be marks on the seal paper.Some NISSIN FOODS products have a sealing sticker attached to the bottom of the sealing film for cooking, and this sticker also serves as an opening aid when removing the sealing film.

Topics about Styrofoam containers
1998/Ministry of the Environment (currentlyMinistry of the Environment) Submitted by the SPEED '98 list (“Environment Agency's response policy to the problem of endocrine disrupting chemicals”), by pouring high-temperature hot water from a polystyrene foam containerEnvironmental hormones(Styrene dimer, styrene trimmer) was eluted, and it was criticized by the mass media that taking it with soup and noodles would have an effect on the human body, and each manufacturer urgently switched to a paper container, which became a big problem. It was.
Later, the theory was re-examined by the cup noodle industry and2000/OldMITI・The former Environment Agency announced that "no evidence of endocrine disrupting effects can be found" and "most reports denial of effects"2006/The Tokyo Metropolitan Institute of Health and Safety announced that animal experiments have confirmed its effects on living organisms. On the other hand, it was argued that the result was under the condition of ingesting 10 times or more of the usual amount, and it is unknown how much the actual effect on the human body is.
Styrofoam (polystyreneAs mentioned above, suspicion of substances related to endocrine disruptors was cleared in November 2000, and is excluded from the list. But,2004/Of the health food that was popular at the timePerilla oil(Sesame oil) Became a topic as melting this styrene cup,National Life CenterInvestigated, and found that when this perilla oil was put in a cup and poured with boiling water at 100 degrees Celsius, a certain amount of dissolution was observed, calling attention to consumers.[5].
2008/AlsoJapan Instant Food Industry AssociationNot only mustard oil and sesame oilFlaxseed oil,Coconut oil(Coconut oil) is also said to melt when placed in cup noodles in a styrene container.[6].


Most products are boiled in water and cooked in 3-5 minutes (various widths of about 1-5 minutes). In the first half of the 1980s, companies released dry noodle type products with a cooking time of 1 minute, but the noodles grow before they finish eating[Annotation 4]Due to problems such as the above, it is not well received by consumers, and most of them have a short lifespan, and only some types of yakisoba survive.[Annotation 5].. In the case of yakisoba type that does not use soup, it is necessary to remove the hot water. There are also products such as raw type noodles that are boiled and then poured again. However, the one using raw type noodles tends to have a slightly shorter cooking time.[Annotation 6]..As a special cooking method, there is a so-called "Katayakisoba" series of yaki udon noodles, which is made by cooking noodles in hot water instead of cooking them in hot water, and then adding fried noodles to it. There are very few cup noodles with such a cooking method.

The attached soup and ingredientsFreeze dry manufacturing methodThe ones that are dried with are the mainstream, but for products in the relatively middle and high price rangeInstant noodles in a bagSimilar to the above, some soups and ingredients are attached.For those products, you can see various differences depending on the product, such as taking out the bag, placing it on the noodles and then pouring hot water, so it is recommended to read the instructions on the package before pouring hot water. Recommended[Annotation 7].. InsideRetort foodThere are also products that come with the ingredients and recommend heating the ingredients in a water bath or a separate pot.In addition, cup noodles2009/May 6Previously released productsJAS standardIt was classified by "standard" and "advanced" by. 6% or more based on the weight of noodles is the standard, 15% or higher is the advanced type, and in the case of cup yakisoba or spaghetti, 4% or more is the standard type and 10% or more is the advanced type. But 2009May 7These classifications have been abolished (discontinued) for the cup noodles that will be released from then on.[7].

There are various means for measuring cooking time, and even in applied software such as mobile phones and smartphones, there is a category called ramen timer (cup noodle timer).If the lid of most cup noodles is paper-based, it will be difficult to reseal it once it is peeled off, and usually it is often necessary to perform auxiliary sealing with another object (book, etc.) during cooking.For this reason, mascot items for auxiliary sealing of cup noodles are on sale, and some also serve as a timer for measuring cooking time. There are also items that incorporate the motif of existing cup noodles, such as "Telecoma Warrior Donburiman".Nisshin Foods is a modified robot item with a cup noodle motif for this purpose.Cup noodle robo timerIs planned and manufactured to coincide with the 40th anniversary of the release of Cup Noodles, and is distributed as a gift product.


For some products sold all over Japan, there are cases where the seasoning is different for each region such as eastern Japan and western Japan ("Donbei" and "Donbei" and "Red fox and green raccoon"Such).There are also products that are sold only in regions.Aomori Prefecture is the number one purchaser of cup noodles.[9].

Japanese manufacturers are also producing locally. As mentioned above, general noodles in the area are often made into cup foods.

NISSIN FOODPolicemen,Health centerAs a result of the investigation, it was concluded that there was no paradichlorobenzene in factories, etc.[16].. Since then, it has been noted that it should not be stored together with insect repellents.

Also, as mentioned above, the physical strength of the cups is relatively low, and most cup noodles have a statement that they are easily damaged, and the handling of cartons for transportation and packaging is clearly broken. There is.

Emergency food

Electricity, gas, water,life lineIt is often difficult to obtain hot water in an emergency that affects people, but according to the Disaster Countermeasures Division, Security Department, Metropolitan Police Department, you can eat water even if you wait for 15 minutes.[17]..In addition, the use of fire immediately after a disaster has a high risk of causing a fire accident due to a gas leak, and it is often difficult to use fire in a group evacuation life, so cooking may be difficult.1989/ToNissin FoodMore, cup noodles that can be cooked simply by pouring water with a heating elementSuper voileWas tested and sold.

At least, cooking is easier than instant noodles, but the water, fuel, and simpleFurnaceOther preparations such as (cassette gas stove, etc.) are required.

National Research and Development AgencyInstitute for medical infrastructure, health and nutritionAnnounced that cup noodles were the number one food source for Japanese salt intake, and instant noodles in bags were number two."It has become clear that excessive salt intake is associated with elevated blood pressure, so please be careful," the institute said.

Ministry of Health, Labor and Welfareの2012年の国民健康・栄養調査のデータを基に、食塩摂取源となっている食品のランキングを作成したところ、1位のカップ麺からはスープを飲み干したと仮定して1日あたり5.5gの食塩を取っていた。2位はインスタントラーメン5.4g、3位は梅干し1.8g、4位は高菜の漬物1.2g、5位はキュウリの漬物1.2gだった[21]..It should be noted that these conditions are particularly difficult to control salt content and avoid overdose in cup noodle types that have been seasoned from the beginning with soups, and Peyang sauce and yakisoba types that are attached with liquid soup.[Annotation 9]However, with Kitsune Donbei type and ordinary bag noodle type instant noodles with powdered soup attached, it is possible to suppress salt content and avoid overdose by reducing the amount of powdered soup used. be.

In February 2020, MYOJO FOODS introduced the "Shio Care Cup", which can adjust the amount of salt intake by carving a line that serves as a guide for leaving soup inside the cup in response to the growing health consciousness of consumers.Introduced as needed, mainly for bowl types whose container shape is not a vertical cup[22].

It has been pointed out that leaving soup is good for your health, but it also leads to clogging of water pipes and environmental pollution.EspeciallyCampThen, it was regarded as a problem to dispose of the remaining soup directly into the river or soil.As a solution to such problems, March 2021Kobayashi PharmaceuticalAnd Nissin Foods jointly developed "Cup Noodle Remaining Soup Hardening Powder".Distributed sequentially through Nisshin Foods online shops, etc.[23]..
