Picual
The Picual, also known as Marteña or Lopereña, is an olive cultivar from Spain. Picual olives are the most commonly grown olive today for olive oil production, with production centered in the Spanish province of Jaén. Picual trees are estimated to account for 25% of all olive oil production in the world. Naturally, this varietal is very high in oil content, at 20-27% by weight. Characteristics Virgin olive oil from Picual olives have high levels of polyphenol Polyphenols () are a large family of naturally occurring organic compounds characterized by multiples of phenol units. They are abundant in plants and structurally diverse. Polyphenols include flavonoids, tannic acid, and ellagitannin, some o ...s (a class of organic organic compounds which are known to have antioxidant effects), typically between 300 and 700ppm. Many Picual groves are primarily harvested when ripe or overripe to maximize oil content, and thus produce oil with poor taste qualities. Less than one ...

Olive Oil
Olive oil is a liquid fat obtained from olives (the fruit of ''Olea europaea''; family Oleaceae), a traditional tree crop of the Mediterranean Basin, produced by pressing whole olives and extracting the oil. It is commonly used in cooking: for frying foods or as a salad dressing. It can be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine; the other two are wheat and grapes. Olive trees have been grown around the Mediterranean since the 8th millennium BC. In 2019–2020, world production of olive oil was . Spain was the largest producer followed by Italy, Tunisia, Greece, Turkey and Morocco. San Marino has by far the largest per capita consumption of olive oil worldwide. The composition of olive oil varies with the cultivar, altitude, time of harvest, and extraction process. It consists mainly of oleic acid (up to 83%), with ...

Olive
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus ''Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Province Of Jaén (Spain)
Jaén () is a province of southern Spain, in the eastern part of the autonomous community of Andalusia. It is bordered by the provinces of Ciudad Real, Albacete, Granada and Córdoba. Its capital is Jaén city. Its area is 13,484 km². Its population is 657,387 (2003), about one sixth of whom living in the capital. It contains 97 municipalities. The highest point of the province is Pico Mágina (2165 m). One of the less-known provinces of Spain, compared to the tourist-oriented coast, it has four national parks and many other protected natural areas. The province also contains two Renaissance cities, Úbeda and Baeza, both recently declared World Heritage Sites by UNESCO. The province has among the highest concentration of castles in the world outside the Levant, thanks to its strategic position during the ''Reconquista''. The annual chess tournament, held until 2010 in Linares, attracted many of the world's best players. The province is the largest producer of olive oil ...

Polyphenol
Polyphenols () are a large family of naturally occurring organic compounds characterized by multiples of phenol units. They are abundant in plants and structurally diverse. Polyphenols include flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments. Etymology The name derives from the Ancient Greek word (''polus'', meaning "many, much") and the word phenol which refers to a chemical structure formed by attaching to an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group as is found in alcohols (hence the ''-ol'' suffix). The term polyphenol has been in use at least since 1894. Definition The term polyphenol is not well-defined, but is generally agreed that they are natural products "having a polyphenol structure (i.e., several hydroxyl groups on aromatic rings)" including four principal classes: "phenolic acids, flavonoids, stilbenes, and lignans". *Flavonoids include flavones, flavonols, flavanols, f ...

Antioxidant Effect Of Polyphenols And Natural Phenols
A polyphenol antioxidant is a hypothetical type of antioxidant containing a polyphenolic substructure and studied in vitro. Numbering over 4,000 distinct species mostly from plants, polyphenols may have antioxidant activity in vitro, but are unlikely to be antioxidants in vivo. Hypothetically, they may affect cell-to-cell signaling, receptor sensitivity, inflammatory enzyme activity or gene regulation, although high-quality clinical research has not confirmed any of these possible effects in humans . Sources of polyphenols The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods. For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content) and vegetables such as broccoli, cabbage, celery, onion and parsley are rich in polyphenols.
