A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, generally occurring in clusters.
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples of berries in the culinary sense are strawberries, raspberries, blueberries, blackberries, white currants, blackcurrants, and redcurrants. In Britain, soft fruit is a horticultural term for such fruits.
Prunus is a genus of trees and shrubs in the flowering plant family Rosaceae that includes plums, cherries, peaches, nectarines, apricots and almonds. The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species as of March 2024.
Morus, a genus of flowering plants in the family Moraceae, consists of 19 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, though the three most common are referred to as white, red, and black, originating from the color of their dormant buds and not necessarily the fruit color, with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. M. alba is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. M. alba is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States.
Flavonoids are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans.
Aronia is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is Aronia melanocarpa which emerged from Eastern North America. The lesser known Aronia arbutifolia and the hybrid form of the abovementioned species called Aronia prunifolia were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species Aronia melanocarpa reached Europe where they were first cultivated in Scandinavia and Russia.
The açaí palm, Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit, hearts of palm, leaves, and trunk wood. Global demand for the fruit has expanded rapidly in the 21st century, and the tree is cultivated for that purpose primarily.
Black rice, also known as purple rice or forbidden rice, is a range of rice types of the species Oryza sativa, some of which are glutinous rice.
Cyanidin is a natural organic compound. It is a particular type of anthocyanidin. It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, hawthorn, loganberry, açai berry and raspberry. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH < 3, violet at pH 7-8, and blue at pH > 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. Cyanidin has been found to be a potent sirtuin 6 (SIRT6) activator.
The health effects of wine are mainly determined by its active ingredient – alcohol. Preliminary studies found that drinking small quantities of wine, particularly of red wine, may be associated with a decreased risk of cardiovascular diseases, cognitive decline, stroke, diabetes mellitus, metabolic syndrome, and early death. Other studies found no such effects.
Red rice is rice that is colored red due to natural anthocyanin content. It is usually eaten unpolished or partially polished, and has a red bran layer, rather than the more common pale brown. Red rice has a nutty flavor. It has the highest nutritional value among rices eaten with the bran intact.
A polyphenol antioxidant is a hypothesized type of antioxidant studied in vitro. Numbering over 4,000 distinct chemical structures mostly from plants, such polyphenols have not been demonstrated to be antioxidants in vivo.
Hibiscus mutabilis, also known as the Confederate rose, Dixie rosemallow, cotton rose or cotton rosemallow, is a plant long cultivated for its showy flowers. Originally native to southern China, it is now found on all continents except Antarctica.
Davidsonia pruriens, also known as ooray, Davidson's plum, or Queensland Davidson's plum, is a medium-sized rainforest tree of northern Queensland, Australia.
Anthocyanins, also called anthocyans, are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart named a chemical compound that gives flowers a blue color, Anthokyan, in his treatise "Die Farben der Blüthen". Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins.
Phenolic compounds—natural phenol and polyphenols—occur naturally in wine. These include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids.
Purple corn or purple maize is group of flint maize varieties originating in South America, descended from a common ancestral variety termed "kʼculli" in Quechua. It is most commonly grown in the Andes of Peru, Bolivia and Ecuador.
Litsea garciae, also known as engkala, engkalak, kangkala, pangalaban and Borneo avocado, is a flowering plant belonging to the family Lauraceae and genus Litsea. It is native to Taiwan, the Philippines, Borneo, the Malay Peninsula, Sumatra, Java, and Sulawesi.
