Instant noodles, or instant ramen, is a type of food consisting of noodles sold in a precooked and dried block with flavoring powder and/or seasoning oil. The dried noodle block was originally created by flash-frying cooked noodles, which is still the dominant method used in Asian countries; air-dried noodle blocks are favored in Western countries. Dried noodle blocks are designed to be cooked or soaked in boiling water before eating. Ramen, a Japanese adaptation of Chinese noodle soup, is sometimes used as a descriptor for instant noodle flavors by some Japanese manufacturers. It has become synonymous in the United States with all instant noodle products.

Instant noodles were invented by Momofuku Ando of Nissin Foods in Japan. They were launched in 1958 under the brand name Chikin Ramen. In the 1960s, they became popular in the United States, and a subsidiary of Nissin Foods was established there. In 1971, Nissin introduced Cup Noodles, the first cup noodle product. Instant noodles are marketed worldwide under many brand names.

The main ingredients in instant noodles are flour, starch, water, salt and/or , a type of alkaline mineral water containing sodium carbonate and usually potassium carbonate, and sometimes a small amount of phosphoric acid. Common ingredients in the flavoring powder are salt, monosodium glutamate, seasoning, and sugar. The flavoring is typically in a separate packet. In cup noodles, flavoring powder is often loose in the cup. Some instant noodle products are seal-packed and can be reheated or eaten straight from the packet or container.

History

The history of noodles in China dates back many centuries, and there is evidence that a noodle that is boiled and then fried and served in a soup, similar to Yi noodle, dates to ancient China. According to legend, during the Qing dynasty, a chef put already-cooked egg noodles in to boil. To rescue them from becoming soggy, he scooped them out and fried them in hot oil, serving them as a soup. According to the Journal of Ethnic Foods, early instant noodle packaging was labeled "Yi noodles".

Modern instant noodles were created by Momofuku Ando in Japan."Inventor of instant noodles dies" BBC News. 6 January 2007 They were first marketed on 25 August 1958 by Ando's company, Nissin, under the brand name Chikin Ramen.

Before Ando invented instant noodles, the process of mechanically curving noodles into a wavy shape had already been invented by Yoshio Murata in 1953. Murata's invention made it possible to curl noodles dozens of times faster, paving the way for the mass production of instant noodles. Curving noodles into a wave shape presents numerous advantages, including more noodles fitting into a small package, lower likelihood of sticking together during cooking, more even cooking, improved flavor, lower fragility during transport and handling, easier malleability, improved elasticity, and decreased likelihood of slipping off chopsticks or forks during consumption.

Ando developed the entire production method of creating "instant" noodles, from the processes of noodle-making, steaming, and seasoning, to dehydrating through flash-frying in hot oil. This dried the noodles and gave them a longer shelf life, exceeding that of frozen noodles. Each noodle block was pre-seasoned and sold for ¥35. The instant noodles became ready to eat in two minutes by adding boiling water. Due to their price and novelty, Chikin Ramen were considered a luxury item initially, as Japanese grocery stores typically sold fresh noodles for one-sixth of their price. Despite this, instant noodles eventually gained immense popularity, especially after being promoted by Mitsubishi Corporation. Initially gaining popularity across East, South, and Southeast Asia, where they are now firmly embedded within local cultures, instant noodles eventually spread to and gained popularity across most other parts of the world.

A separate claim of origin for instant noodles comes from Pingtung County in Taiwan. Chang Kuo-wen, a Pingtung local, filed a patent for instant noodles in 1956. On 16 August 1961, Zhang supposedly transferred the patent to Momofuku Ando for ¥23million.

In 1966, when Ando was in the United States promoting Chikin Ramen, he observed how Americans would divide up a ramen block, put it in a paper cup, and pour boiling water over it, inspiring him with the idea for his new product. In 1971, Nissin introduced Nissin Cup Noodles, a cup noodle to which boiling water is added to cook the noodles. Dried vegetables began to be included in the cup, creating a complete instant soup dish. Cup noodles combine the functions of packaging material, a container for adding boiling water, and a bowl to eat the noodles from. Heading off rise in health consciousness, many manufacturers launched instant noodles with various healthy recipes: noodles with dietary fiber and collagen, low-calorie noodles, and low-sodium noodles.

In a Japanese poll conducted in 2000, instant noodles were voted the best Japanese invention of the 20th century. BBC News , approximately 103billion servings of instant noodles were eaten worldwide every year. China consumed 40billion packages of instant noodles per year (39% of world consumption), Indonesia 12billion, India 6billion, Japan 5.7billion, and Vietnam 5.2billion. The top three per-capita consuming nations are South Korea (74.6 servings), Vietnam (53.9 servings), and Nepal (53 servings).

Composition

There are three key ingredients in wheat-based noodles: wheat flour, water, and salt. Other than the three main ingredients, USDA regulations allow instant noodles to contain palm oil, seasoning, sodium phosphates, potato starches, gums, and other ingredients.

Flour Noodles can be made from different kinds of flours, such as wheat, rice, and buckwheat flour. For instant noodles, flours that have 8.5–12.5% protein are optimal because noodles must be able to withstand the drying process without breaking apart, which requires a higher amount of protein in flour, and during frying, high protein content can help decrease the fat uptake. Gluten, which is made up of glutenin and gliadin, is the most important wheat protein that forms the continuous viscoelastic dough of noodles. Water The hydration of dough determines the development of gluten structure, which affects the viscoelastic properties of dough. The water absorption level for making noodles is about 30%–38% of flour weight; if the water absorption level is too high, hydration of flour cannot be completed, and if the water absorption level is too low, the dough will be too sticky to handle during processing. For instant noodles, dehydration is an important step after noodles are made because water can offer a hospitable environment for microorganisms. The USDA uses different regulations of moisture content, depending on dehydration method: for instant noodles dehydrated by frying, moisture content cannot exceed 8%, and for those dehydrated by methods other than frying, moisture content cannot exceed 14.5%. Salt Salt is added when making the flour dough to strengthen gluten structures and enhance the sheeting properties of dough, and it can make the noodles softer and more elastic. Salt also offers the basic salty flavor of noodles and can mask flavours generated by flour and processing. Another function of salt is to slow down the activities of enzymes, such as proteolytic enzymes, which could interrupt the gluten structures and microbial growth. Alkaline salt, such as sodium and potassium carbonates, could be added to noodle dough to enhance the yellow color of the product if needed because flavonoid pigments in flour turn yellow at alkaline pH levels, and the increase of pH could also influence the behavior of gluten, which could make noodle dough even tougher and less extensible (for some noodles, such as Japanese ramen, this is wanted). For making fresh noodles, the amount of salt added is 1–3% of flour weight, but instant noodles require higher salt content due to their longer shelf life. One pack of ramen contains well over half the daily recommended amount of sodium.

, an alkaline solution consisting usually of a 9:1 ratio of sodium carbonate to potassium carbonate, is added to the flour and water when making ramen to help develop several of its unique characteristics. The addition of aids in the gluten development of the noodle as well as promotion of gelatinization of starches, both of which contribute to the springiness and chewiness characteristic of ramen. Additionally, the addition of enhances the yellow color of ramen noodles by bringing about a chromophoric shift of several compounds called flavonoids that are inherent in wheat flour. Oil Frying is a common dehydration process for producing instant noodles. According to USDA regulations, oil-fried instant noodles should not have a combined fat content of ingredients and frying higher than 20% of total weight. Palm oil is chosen as the frying oil for instant noodles due to its heat stability and low cost. Due to their high fat and low moisture content, instant noodles are susceptible to lipid oxidation, and relatively high amounts of antioxidant preservatives, such as TBHQ, are added. Hence, to avoid the generation of off-flavors and health-risking compounds, some instant noodles are dehydrated by ways other than frying to reduce fat content. According to the USDA, non-fried instant noodles should have a fat content lower than 3%. Other ingredients Potato starches are commonly added to instant noodles to enhance the gelling properties and water-holding capacities of noodles. Polyphosphate is used in instant noodles as an additive to improve starch gelatinization during cooking (rehydration), to allow more water retention in the noodles. Hydrocolloids such as guar gum are widely used in instant noodle production to enhance water-binding capacity during rehydration and to shorten cooking time. Gums are dispersed in water before mixing and making of noodles dough.

Production

Noodle production starts with dissolving the salt, starch, and flavoring in water to form a mixture that is then added to the flour. The dough is then left for a period of time to mature, then for even distribution of the ingredients and hydration of the particles in the dough, it is kneaded. After it is kneaded, the dough is made into two sheets compounded into one single noodle belt by being put through two rotating rollers. This process is repeated to develop gluten more easily as the sheet is folded and passed through the rollers several times. This will create the stringy and chewy texture found in instant noodles. When the noodle belt is made to the desired thickness by adjusting the gap in the rolls, it is then cut right away. Wavy noodles are made in a slow-paced conveyor belt and are hindered by metal weights when coming out of the slitter, which gives the noodle its wavy appearance. If the strands are to be molded into other shapes, liquid seasoning can be added as well. Once the noodles are shaped, they are ready to be steamed for 1–5 minutes at to improve texture by gelatinizing the starch of the noodles. When steaming, the addition of water and heat breaks up the helix structure and crystallinity of amylose. Amylose begins to diffuse out of the starch granule and forms a gel matrix around the granule.
