Grape Seed Oil
Grape seed oil (also called grapeseed oil or grape oil) is a vegetable oil derived from the seeds of grapes. Grape seeds are a winemaking by-product, and oil made from the seeds is commonly used as an edible oil. Description Grape seed oil has a moderately high smoke point of approximately . The oil has a light taste and a high polyunsaturated fat content, making it suitable for use in salad dressings, mayonnaise and as a base for oil infusions of garlic, rosemary, or other herbs or spices. It is widely used in baked goods, pancakes, and waffles. It is sprayed on raisins to help them retain their flavor. Uses Grapeseed oil may be used as a salad oil, massage oil, and in manufactured cosmetics or haircare products. Research A study of 21 grape cultivars showed variation of oil composition, especially for linoleic acid and tocopherols. Although grape seeds contain polyphenols, such as proanthocyanidins, grape seed oil contains negligible amounts of these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmitic Acid
Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms.Gunstone, F. D., John L. Harwood, and Albert J. Dijkstra. The Lipid Handbook, 3rd ed. Boca Raton: CRC Press, 2007. , Its chemical formula is , and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0. It is a major component of palm oil from the fruit of '' Elaeis guineensis'' ( oil palms), making up to 44% of total fats. Meats, cheeses, butter, and other dairy products also contain palmitic acid, amounting to 50–60% of total fats. Palmitates are the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4). Major sources of C16:0 are palm oil, palm kernel oil, coconut oil, and milk fat. Occurrence and production Palmitic acid was discovered by saponification of palm oil, which process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garlic
Garlic (''Allium sativum'') is a species of bulbous flowering plants in the genus '' Allium''. Its close relatives include the onion, shallot, leek, chives, Welsh onion, and Chinese onion. Garlic is native to central and south Asia, stretching from the Black Sea through the southern Caucasus, northeastern Iran, and the Hindu Kush; it also grows wild in parts of Mediterranean Europe. There are two subspecies and hundreds of varieties of garlic. Garlic has been used for thousands of years as a seasoning, culinary ingredient, traditional medical remedy; it was known in many ancient civilizations, including the Babylonians, Egyptians, Romans, and Chinese, and remains significant in many cuisines and folk treatments, especially across the Mediterranean and Asia. Garlic propagates in a variety of climates and conditions and is produced globally; China is by far the largest producer, accounting for over two thirds (73%) of the world's supply in 2021.

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 ...

Tocopherols
Tocopherols (; TCP) are a class of organic compounds comprising various Methyl group, methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named ''tocopherol'', from Greek wiktionary:τόκος, τόκος ''tókos'' 'birth' and wiktionary:φέρειν, φέρειν ''phérein'' 'to bear or carry', that is 'to carry a pregnancy', with the ending ''-ol'' signifying its status as a chemical Alcohol (chemistry), alcohol. Α-tocopherol, α-Tocopherol is the main source found in supplements and in the European diet, where the main dietary sources are olive and sunflower oils, while G-tocopherol, γ-tocopherol is the most common form in the American diet due to a higher intake of soybean and corn oil. Forms Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to re ...

Linoleic Acid
Linoleic acid (LA) is an organic compound with the formula . Both alkene groups () are ''cis''. It is a fatty acid sometimes denoted 18:2 (n−6) or 18:2 ''cis''-9,12. A linoleate is a salt or ester of this acid. Linoleic acid is a polyunsaturated, omega−6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents. It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid. It is one of two essential fatty acids for humans, who must obtain it through their diet, and the most essential, because the body uses it as a base to make the others. The word "linoleic" derives , reflecting the fact that it was first isolated from linseed oil. History In 1844, F. Sacc, working at the laboratory of Justus von Liebig Justus ''Freiherr'' von Liebig (12 May 1803 – 18 April 1873) was a Germans, German scientist who made major contributions to the theory, practice, and pedagogy of che ...

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] |
Haircare
Hair care or haircare is an overall term for hygiene and cosmetology involving the hair which grows from the human scalp, and to a lesser extent facial, pubic and other body hair. Hair care routines differ according to an individual's culture and the physical characteristics of one's hair. Hair may be colored, trimmed, shaved, plucked or otherwise removed with treatments such as waxing, sugaring and threading. Hair care services are offered in salons, barbershops and day spas, and products are available commercially for home use. Laser hair removal and electrolysis are also available, though these are provided (in the US) by licensed professionals in medical offices or specialty spas. Hair cleaning and conditioning Biological processes and hygiene Care of the hair and care of the scalp skin may appear separate, but are actually intertwined because hair grows from beneath the skin. The living parts of hair (hair follicle, hair root, root sheath and sebaceous gland) are ben ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmetics
Cosmetics are substances that are intended for application to the body for cleansing, beautifying, promoting attractiveness, or altering appearance. They are mixtures of chemical compounds derived from either Natural product, natural sources or created synthetically. Cosmetics have various purposes, including personal care, personal and skin care. They can also be used to conceal blemishes and enhance natural features (such as the eyebrows and eyelashes). Makeup can also add colour to a person's face, enhance a person's features or change the appearance of the face entirely to resemble a different person, creature, or object. People have used cosmetics for thousands of years for skin care and appearance enhancement. Visible cosmetics for both women and men have gone in and out of fashion over the centuries.

Massage Oil
Massage is the rubbing or kneading of the body's soft tissues. Massage techniques are commonly applied with hands, fingers, elbows, knees, forearms, feet, or a device. The purpose of massage is generally for the treatment of body stress or pain. In English-speaking European countries, traditionally a person professionally trained to give massages is known by the gendered French loanwords ''masseur'' (male) or ''masseuse'' (female). In the United States, these individuals are often referred to as "massage therapists". In some provinces of Canada, they are called "registered massage therapists." In professional settings, clients are treated while lying on a massage table, sitting in a massage chair, or lying on a mat on the floor. There are many different modalities in the massage industry, including (but not limited to): deep tissue, manual lymphatic drainage, Medical massage, medical, sports, Structural Integration, structural integration, #Swedish massage, Swedish, Thai massa ...

Salad Oil
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of edible plants. Like animal fats, vegetable fats are ''mixtures'' of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of plants. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. History In antiquity Olive oil has been a part of human culture for millennia.Ruth Schuster (December 17, 2014). "8,000-year old olive oil found in Galilee, earliest known in world", ''Haaretz''. Retrieved December 17, 2014. Archaeological evidence shows that olives were turned into olive oil by 6000 BC and 4500 BC in present-day Israel.

Raisins
A raisin is a dried grape. Raisins are produced in many regions of the world and may be eaten raw or used in cooking, baking, and brewing. In the United Kingdom, Ireland, New Zealand, Australia and South Africa, the word ''raisin'' is reserved for the dark-colored dried large grape, with '' sultana'' being a golden- or green-colored dried grape, and '' currant'' being a dried small Black Corinth seedless grape. Varieties Raisin varieties depend on the types of grapes used and appear in a variety of sizes and colors, including green, black, brown, purple, blue, and yellow. Seedless varieties include sultanas (the common American type is known as Thompson Seedless in the United States), Zante currants (black Corinthian raisins, ''Vitis vinifera'' L. var. Apyrena), and Flame grapes. Raisins are traditionally sun-dried but may also be artificially dehydrated. Golden raisins are created with a treatment of sulfur dioxide rather than purely drying them. They are sometimes dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pancake
A pancake, also known as a hotcake, griddlecake, or flapjack, is a flat type of batter bread like cake, often thin and round, prepared from a starch-based Batter (cooking), batter that may contain eggs, milk, and butter, and then cooked on a hot surface such as a griddle or frying pan. Archaeological evidence suggests that pancakes were probably eaten in prehistoric societies. The pancake's shape and structure varies worldwide. In England, pancakes are often Leavening agent, unleavened and resemble a crêpe. In Scotland and North America, a leavening agent is used (typically baking powder) creating a thick fluffy pancake. A ''crêpe'' is a thin pancake of Brittany, Breton origin cooked on one or both sides in a special pan or crepe maker to achieve a lacelike network of fine bubbles. A well-known variation originating from southeast Europe is palatschinke, a thin moist pancake fried on both sides and filled with jam, cream cheese, chocolate, or ground walnuts, but many other f ...
