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 has high levels of polyphenol Polyphenols () are a large family of naturally occurring phenols. They are abundant in plants and structurally diverse. Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as ...s (a class of 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 quarter of ...

Olive Oil
Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of ''Olea europaea'', a traditional Tree fruit, tree crop of the Mediterranean Basin) and extracting the oil. It is commonly used in cooking for frying foods, as a condiment, or as a salad dressing. It can also 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, with wheat and grapes. Olive trees have been cultivated around the Mediterranean since the 8th millennium BC. In 2022, Spain was the world's largest producer, manufacturing 24% of the world's total. Other large producers were Italy, Greece, and Turkey, collectively accounting for 59% of the global market. 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 smaller amounts of other fatty acids ...

Olive
The olive, botanical name ''Olea europaea'' ("European olive"), is a species of Subtropics, subtropical evergreen tree in the Family (biology), family Oleaceae. Originating in Anatolia, Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern Cultivar, cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, ''Olea'', and lends its name to the Oleaceae plant family, which includes species such as Syringa vulgaris, lilac, jasmine, forsythia, and Fraxinus, ash. The olive fruit is classed botanically as a drupe, similar to the cherry or peach. The term oil—now used to describe any Viscosity, viscous Hydrophobe, water-insoluble liquid—was virtually synonymous with olive oil, the Vegetable oil, liquid fat made from olives. The olive has deep historical, economic, and cultural significance in the Mediterranean; Georges Duhamel (author), George ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spain, or the Kingdom of Spain, is a country in Southern Europe, Southern and Western Europe with territories in North Africa. Featuring the Punta de Tarifa, southernmost point of continental Europe, it is the largest country in Southern Europe and the fourth-most populous European Union member state. Spanning across the majority of the Iberian Peninsula, its territory also includes the Canary Islands, in the Eastern Atlantic Ocean, the Balearic Islands, in the Western Mediterranean Sea, and the Autonomous communities of Spain#Autonomous cities, autonomous cities of Ceuta and Melilla, in mainland Africa. Peninsular Spain is bordered to the north by France, Andorra, and the Bay of Biscay; to the east and south by the Mediterranean Sea and Gibraltar; and to the west by Portugal and the Atlantic Ocean.

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 the city of Jaén. It has a total area of 13,484 km². Its population is 619,938 as of 1 July 2023, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphenol
Polyphenols () are a large family of naturally occurring phenols. They are abundant in plants and structurally diverse. Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning (leather), tanning garments. Etymology The name derives from the Ancient Greek word (, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group (hence the ''-ol'' suffix). The term "polyphenol" has been in use at least since 1894. Definition Polyphenols are natural products with "one or several hydroxyl groups on aromatic rings", including four principal classes: phenolic acids, flavonoids, stilbenes, and lignans. Flavonoids can be grouped as flavones, flavonols, flavanols, flavanones, isoflavones, proanthocyanidins, and anthocyanins. Particularly abundant flavanoids in foods are catechin (tea, frui ...

Antioxidant Effect Of Polyphenols And Natural Phenols
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. In vitro at high experimental doses, polyphenols may affect cell-to-cell signaling, receptor sensitivity, inflammatory enzyme activity or gene regulation. None of these hypothetical effects has been confirmed in humans by high-quality clinical research, . 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.
