Poppy Seed Oil
Poppyseed oil (also poppy seed oil and poppy oil) is an edible oil obtained from poppy seeds (specifically seeds of ''Papaver somniferum'', the opium poppy). Poppy seeds yield 45–50% oil. Like poppy seeds, poppyseed oil is highly palatable, high in vitamin E, and has no narcotic properties. Poppy seeds are especially high in tocopherols other than vitamin E (alpha-tocopherol). Compared to other vegetable oils, poppyseed oil has a moderate amount of phytosterols: higher than soybean oil and peanut oil, lower than safflower oil, sesame oil, wheat germ oil, corn oil, and rice bran oil. It has little or no odor and a pleasant taste, and it is less likely than some other oils to become rancid. Uses The oil is sometimes used as a cooking oil; it is also used for moisturizing skin. Its primary use, however, is in the manufacture of paints, varnishes, and soaps. Poppyseed oil is a drying oil. In oil painting, the most popular oil for binding pigment, thinning paint, and varnishi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytosterol
Phytosterols are phytosteroids, similar to cholesterol, that serve as structural components of biological membranes of plants. They encompass plant sterols and stanols. More than 250 sterols and related compounds have been identified. Free phytosterols extracted from oils are insoluble in water, relatively insoluble in oil, and soluble in alcohols. Phytosterol-enriched foods and dietary supplements have been marketed for decades. Despite well-documented LDL cholesterol-lowering effects from long-term consumption of phytosterols, there is insufficient evidence for an effect on cardiovascular diseases, fasting blood sugar, glycated hemoglobin, or overall mortality rate. Structure They have a fused polycyclic structure and vary in carbon side chains and / or presence or absence of a double bond (saturation). They are divided into 4,4-dimethyl phytosterols, 4-monomethyl phytosterols, and 4-desmethyl phytosterols based on the location of methyl groups at the carbon-4 position. St ...

Rice Bran Oil
Rice bran oil is the oil extracted from the hard outer brown layer of rice called bran. It is known for its high smoke point of and mild flavor, making it suitable for high-temperature cooking methods such as stir frying and deep frying. It is popular as a cooking oil in East Asia, the Indian subcontinent, and Southeast Asia including India, Nepal, Bangladesh, Indonesia, Japan, Southern China and Malaysia. Composition and properties Rice bran oil has a composition similar to that of peanut oil, with 38% monounsaturated, 37% polyunsaturated, and 25% saturated fatty acids. A component of rice bran oil is the γ-oryzanol, at around 2% of crude oil content. Thought to be a single compound when initially isolated, γ-oryzanol is now known to be a mixture of steryl and other triterpenyl esters of ferulic acids. Also present are tocopherols and tocotrienols (two types of vitamin E) and phytosterols. ;Fatty acid composition ;Physical properties of crude and refined rice bran oi ...

Cooking Oils
Cooking oil is plant, animal, or synthetic liquid fat used in frying, baking, and other types of cooking. It is also used in food preparation and flavoring not involving heat, such as salad dressings and bread dips, and may be called edible oil. Cooking oil is typically a liquid at room temperature, although some oils that contain saturated fat, such as coconut oil, palm oil and palm kernel oil are solid. There are a wide variety of cooking oils from plant sources such as olive oil, palm oil, soybean oil, canola oil (rapeseed oil), corn oil, peanut oil and other vegetable oils, as well as animal-based oils like butter and lard. Oil can be flavored with aromatic foodstuffs such as herbs, chillies or garlic. Cooking spray is an aerosol of cooking oil. Health and nutrition While consumption of small amounts of saturated fats is common in diets, meta-analyses found a significant correlation between ''high consumption'' of saturated fats and blood LDL concentration, a risk fa ...

Poppy Seeds
Poppy seed is an oilseed obtained from the opium poppy (''Papaver somniferum''). The tiny, kidney-shaped seeds have been harvested from dried seed pods by various civilizations for thousands of years. It is still widely used in many countries, especially in Central Europe and South Asia, where it is legally grown and sold in shops. The seeds are used whole or ground into meal as an ingredient in many foods – especially in pastry and bread – and they are pressed to yield poppyseed oil. History The poppy seed is mentioned in ancient medical text from many civilizations. For instance, the Egyptian papyrus scroll named Ebers Papyrus, written c. 1550 BC, lists poppy seed as a sedative. The Minoan civilization (approximately 2700 to 1450 BC), a Bronze Age civilization which arose on the island of Crete, cultivated poppies for their seed, and used a milk, opium and honey mixture to calm crying babies. The Sumerians are another civilization that are known to have grown poppy seed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fat Over Lean
Fat over lean refers to the principle in oil painting of applying paint with a higher oil to pigment ratio ('fat') over paint with a lower oil to pigment ratio ('lean') to ensure a stable paint film, since it is believed that the paint with the higher oil content remains more flexible. Oil paint dries at different rates due to the differing drying properties of the constituent pigment. However, everything else being equal, the higher the oil to pigment ratio, the longer the oil binder will take to oxidize, and the more flexible the paint film will be. Conversely, the lower the oil content, the faster the paint dries, and the more brittle it will be. Ignoring this practice, even in some '' alla prima'' painting, may result in a cracked and less durable paint film. It has been claimed by some paint manufacturers that the 'fat-over-lean' principle can be circumvented by using synthetic, alkyd-based painting media such as Galkyd and Liquin. These media do provide consistent drying time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hazelnut Oil
The hazelnut is the fruit of the hazel tree and therefore includes any of the nuts deriving from species of the genus ''Corylus'', especially the nuts of the species ''Corylus avellana''. They are also known as cobnuts or filberts according to species. Hazelnuts are used in baking and desserts, confectionery to make praline, and also used in combination with chocolate for chocolate truffles and products such as chocolate bars, hazelnut cocoa spread such as Nutella, and Frangelico liqueur. Hazelnut oil, pressed from hazelnuts, is strongly flavored and used as a cooking oil. Turkey and Italy are the world's two largest producers of hazelnuts. Description A cob is roughly spherical to oval, about long and in diameter, with an outer fibrous husk surrounding a smooth shell, while a filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about seven to eight months after pollination. The kernel of the seed is edible and us ...

Adulteration
An adulterant is caused by the act of adulteration, a practice of secretly mixing a substance with another. Typical substances that are adulterated include but are not limited to food, cosmetics, pharmaceuticals, fuel, or other chemicals, that compromise the safety or effectiveness of the said substance. It will not normally be present in any specification or declared substances due to accident or negligence rather than intent, and also for the introduction of unwanted substances after the product has been made. Adulteration, therefore, implies that the adulterant was introduced deliberately in the initial manufacturing process, or sometimes that it was present in the raw materials and should have been removed, but was not. An adulterant is distinct from, for example, permitted food preservatives. There can be a fine line between adulterant and additive; chicory may be added to coffee to reduce the cost or achieve a desired flavor—this is adulteration if not declared, but m ...

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocontrast
Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iodine, or more rarely barium sulfate. The contrast agents absorb external X-rays, resulting in decreased exposure on the X-ray detector. This is different from radiopharmaceuticals used in nuclear medicine which emit radiation. Magnetic resonance imaging (MRI) functions through different principles and thus MRI contrast agents have a different mode of action. These compounds work by altering the magnetic properties of nearby hydrogen nuclei. Types and uses Radiocontrast agents used in X-ray examinations can be grouped in positive (iodinated agents, barium sulfate), and negative agents (air, carbon dioxide, methylcellulose). Iodine (circulatory system) Iodinated contrast contains iodine. It is the main type of radiocontrast used for intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipiodol
Lipiodol, also known as ethiodized oil, is a poppyseed oil used by Injection (medicine), injection as a radio-opaque contrast agent that is used to outline structures in radiological investigations. It is used in Transcatheter arterial chemoembolization, chemoembolization applications as a contrast agent in follow-up imaging. Lipiodol is also used in lymphangiography, the imaging of the lymphatic system. It has an additional use in gastric varices, gastric variceal obliteration as a dilutant that does not affect polymerization of cyanoacrylate. Indications Recently, there has been an increasing interest in the use of Lipiodol as a therapeutic agent in the management of unexplained infertility, using a procedure called Lipiodol flushing. There have been a small number of studies that suggest that flushing the media through the tubes gives a short-term rise in fecundity in patients with unexplained infertility. A systematic review has suggested a significant increase in fertility, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walnut Oil
Walnut oil is oil extracted from walnuts, ''Juglans regia''. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats. Composition Walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), oleic acid (13%), and saturated fats (9%). Culinary use Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan-frying, most avoid walnut oil for high-temperature cooking because heating tends to reduce the oil's flavour and produce a slight bitterness. Walnut oil is preferred in cold dishes such as salad dressings. Cold-pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller-pressed and saturated with solvent to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
