Kōji (food)
Kōji (, also written as the kokuji ) is a filamentous fungus, most commonly ''Aspergillus oryzae'', which are traditionally used in Japanese cuisine for the fermentation of food, or a mixture of such a culture with wheat and soybean meal. The latter can be fried and eaten directly or processed to a sauce.René Redzepi, David Zilber: ''The Noma Handbook Fermentation - How to make Koji, Kombucha, Shoyu, Miso, Vinegar, Garum, lacto-fermented and black fruits and vegetables and cook with them.'' 5th edition, A. Kunstmann, 2019. . The term ''kōji'' in English refers specifically to the Japanese types of starter cultures. The same Chinese character (, more commonly written as the homophonic in simplified Chinese texts) is used in Chinese to refer to Chinese starter cultures; see jiuqu. In Japanese, the genus ''Aspergillus'' is known with the common name of , though the term is not fully limited to the genus (for example, ''Monascus purpureus'' is called "red kōji mold").

Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant in the morning glory family, Convolvulaceae. Its sizeable, starchy, sweet-tasting tuberous roots are used as a root vegetable, which is a staple food in parts of the world. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Moreover, the young shoots and leaves are occasionally eaten as greens. The sweet potato and the potato are in the order Solanales, making them distant relatives. Although darker sweet potatoes are often known as "yams" in parts of North America, they are even more distant from actual yams, which are monocots in the order Dioscoreales. The sweet potato is native to the tropical regions of South America in what is present-day Ecuador. Of the approximately 50 genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some others are used locally (e.g., ''I. aquatica'' "ka ...

Fermented Bean Paste
Fermented bean paste is a category of fermented foods typically made from ground soybeans, which are indigenous to the cuisines of East, South and Southeast Asia. In some cases, such as the production of '' miso'', other varieties of beans, such as broad beans, may also be used. The pastes are usually salty and savoury, but may also be spicy, and are used as a condiment to flavour foods such as stir-fries, stews, and soups. The colours of such pastes range from light tan to reddish brown and dark brown. The differences in colour are due to different production methods, such as the conditions of fermentation, the addition of wheat flour, pulverized mantou, rice, or sugar and the presence of different microflora, such as bacteria or molds used in their production, as well as whether the soybeans are roasted (as in ''chunjang'') or aged (as in ''tauco'') before being ground. Fermented bean pastes are sometimes the starting material used in producing soy sauces, such as tamari ...

Tsukemono
are Japanese preserved vegetables (usually pickled in salt, brine, or a bed of rice bran). They are served with rice as an '' okazu'' (side dish), with drinks as an '' otsumami'' (snack), as an accompaniment to or garnish for meals, and as a course in the kaiseki portion of a Japanese tea ceremony. Alternative names Tsukemono are also referred to as , , or , all carrying the meaning of "fragrant dish" in Japanese. The ''ko'' or portion in these names means "fragrant", and the term was used as a '' nyōbō kotoba'' or "woman's word" for miso in reference to the smell. Over time, this term was also applied to pickles, again for the smell. ''Oshinko'' ("fresh fragrance") more specifically referred to vegetables that had been only lightly pickled and that had not yet changed color very much. The term is now also used more broadly to refer to pickles in general. Making tsukemono To make tsukemono, one needs a container, salt, and something to apply downward pressur ...

Sake
Sake, , or saki, also referred to as Japanese rice wine, is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name ''Japanese rice wine'', sake, and indeed any East Asian rice wine (such as huangjiu and cheongju), is produced by a brewing process more akin to that of beer, where starch is converted into sugars that ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes. The brewing process for sake differs from the process for beer, where the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like other rice wines, when sake is brewed, these conversions occur simultaneously. The alcohol content differs between sake, wine, and beer; while most beer contains 3–9% ABV, wine generally contains 9–16% ABV, and undiluted sake contains 18–20% ABV (although this is often lowered to abou ...

Miso
is a traditional Japanese seasoning. It is a thick paste produced by fermenting soybeans with salt and kōji (the fungus ''Aspergillus oryzae''), and sometimes rice, barley, seaweed, or other ingredients. It is used for sauces and spreads; pickling vegetables, fish, or meats; and mixing with dashi soup stock to serve as miso soup, a Japanese culinary staple food. Miso is high in protein and rich in minerals, and it played an important nutritional role in feudal Japan. Miso is widely used in both traditional and modern cooking in Japan, and as of 2018 had been gaining worldwide interest. Typically, miso is salty, but its flavor and aroma depend on the ingredients and fermentation process. Different varieties of miso have been variously described as salty, sweet, earthy, fruity, or savory. History The origin of miso of Japan is not completely clear. *Grain and fish misos had been manufactured in Japan since the Neolithic era (Jōmon period, 14,000–300 BC). These are ca ...

Soy Sauce
Soy sauce (sometimes called soya sauce in British English) is a liquid condiment of China, Chinese origin, traditionally made from a fermentation (food), fermented paste of soybeans, roasted cereal, grain, brine, and ''Aspergillus oryzae'' or ''Aspergillus sojae'' Mold (fungus), molds. It is recognized for its saltiness and pronounced umami taste. Soy sauce was created in its current form about 2,200 years ago during the Western Han dynasty of ancient China. Since then, it has become an important ingredient in List of Asian cuisines, East and Cuisine of Southeast Asia, Southeast Asian cooking as well as a condiment worldwide. Use and storage Soy sauce can be added directly to food, and is used as a dip or Salt#Edible salt, salt flavor in cooking. It is often eaten with rice, Japanese noodles, noodles, and sushi or sashimi, or can also be mixed with ground wasabi for dipping. Bottles of soy sauce for the salty seasoning of various foods are common on restaurant tables in many co ...

Spores
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, a diploid spore is also produced in some algae, or fungi. Under favourable conditions, the s ...

Umami
Umami ( from ), or savoriness, is one of the five basic tastes. It is characteristic of broths and cooked meats. People taste umami through taste receptors that typically respond to glutamates and nucleotides, which are widely present in meat broths and fermented products. Glutamates are commonly added to some foods in the form of monosodium glutamate (MSG), and nucleotides are commonly added in the form of disodium guanylate, inosine monophosphate (IMP) or guanosine monophosphate (GMP). Since umami has its own receptors rather than arising out of a combination of the traditionally recognized taste receptors, scientists now consider umami to be a distinct taste. Foods that have a strong umami flavor include meats, shellfish, fish (including fish sauce and preserved fish such as Maldives fish, '' katsuobushi'', sardines, and anchovies), '' dashi'', tomatoes, mushrooms, hydrolyzed vegetable protein, meat extract, yeast extract, kimchi, cheeses, and soy sauce. In 1908, ...

Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid ...

Aspartic Acid
Aspartic acid (symbol Asp or D; the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins. The L-isomer of aspartic acid is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. D-aspartic acid is one of two D-amino acids commonly found in mammals. Apart from a few rare exceptions, D-aspartic acid is not used for protein synthesis but is incorporated into some peptides and plays a role as a neurotransmitter/ neuromodulator. Like all other amino acids, aspartic acid contains an amino group and a carboxylic acid. Its α-amino group is in the protonated –NH form under physiological conditions, while its α-carboxylic acid group is deprotonated −COO− under physiological conditions. Aspartic acid has an acidic side chain (CH2COOH) which reacts with other amino acids, enzymes and proteins in the body. Under physiological conditions (pH 7.4) in proteins the side chain usually occurs as the negatively charged a ...
