5-Hydroxymaltol, a derivative of maltol, is a substance that can be found in Penicillium echinulatum . [1] It is also found in toasted oak [2] and also in honeys from blue gum ( Eucalyptus leucoxylon ) and yellow box ( Eucalyptus melliodora ). [3]
Blue cheese or bleu cheese is cheese made with cultures of the mold Penicillium, giving it spots or veins of the mold throughout the cheese, which can vary in color through various shades of blue and green. This carries a distinct smell, either from that or various specially cultivated bacteria. Some blue cheeses are injected with spores before the curds form, and others have spores mixed in with the curds after they form. Blue cheeses are typically aged in a temperature-controlled environment such as a cave. Blue cheese can be eaten by itself or can be spread, crumbled or melted into or over a range of other foods. Blue cheese is known for its pungent creamy texture.
Eucalyptus globulus, commonly known as southern blue gum or blue gum, is a species of tall, evergreen tree endemic to southeastern Australia. This Eucalyptus species has mostly smooth bark, juvenile leaves that are whitish and waxy on the lower surface, glossy green, lance-shaped adult leaves, glaucous, ribbed flower buds arranged singly or in groups of three or seven in leaf axils, white flowers and woody fruit.
Ellagic acid is a natural phenol antioxidant found in numerous fruits and vegetables. Ellagic acid is the dilactone of hexahydroxydiphenic acid. There is no scientific evidence that consuming ellagic acid has any beneficial effect on human health or prevents diseases.
Penicillium roqueforti is a common saprotrophic fungus in the genus Penicillium. Widespread in nature, it can be isolated from soil, decaying organic matter, and plants.
Carvacrol, or cymophenol, C6H3(CH3)(OH)C3H7, is a monoterpenoid phenol. It has a characteristic pungent, warm odor of oregano.
Eucalyptol is a monoterpenoid. A colorless liquid, it is a bicyclic ether. Eucalyptol has a fresh mint-like smell and a spicy, cooling taste. It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up 90% of eucalyptus oil. Eucalyptol forms crystalline adducts with hydrohalic acids, o-cresol, resorcinol, and phosphoric acid. Formation of these adducts is useful for purification.
Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.
Eucalyptus melliodora, commonly known as yellow box, honey box or yellow ironbark, is a species of medium-sized to occasionally tall tree that is endemic to south-eastern, continental Australia. It has rough, flaky or fibrous bark on part or all of the trunk, smooth greyish to yellowish bark above. The adult leaves are lance-shaped to egg-shaped, the flower buds are arranged in groups of seven and the fruit is more or less hemispherical.
Eucalyptus leucoxylon, commonly known as yellow gum, blue gum or white ironbark, is a species of small to medium-sized tree that is endemic to south-eastern continental Australia. It has smooth yellowish bark with some rough bark near the base, lance-shaped or curved adult leaves, flower buds in groups of three and cylindrical, barrel-shaped or shortened spherical fruit. A widely cultivated species, it has white, red or pink flowers.
tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol.
Anthocyanins are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue or black. 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.
Castalagin is an ellagitannin, a type of hydrolyzable tannin, found in oak and chestnut wood and in the stem barks of Anogeissus leiocarpus and Terminalia avicennoides.
Grandinin is an ellagitannin. It can be found in Melaleuca quinquenervia leaves and in oaks species like the North American white oak and European red oak. It shows antioxydant activity. It is an astringent compound. It is also found in wine, red or white, aged in oak barrels.
Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4.
Penicillium echinulatum is a mold species in the genus Penicillium. It is a source of cellulase.
8,5′-Diferulic acid is a non cyclic type of diferulic acid. It is the predominant diferulic acid in sugar beet pulp. It is also found in barley, in maize bran and rye. 8,5′-Diferulic acid has also been identified to be covalently linked to carbohydrate moieties of the arabinogalactan-protein fraction of gum arabic.
Urolithins are microflora human metabolites of dietary ellagic acid derivatives such as ellagitannins. They are produced in the human gut, and found in the urine in the form of urolithin B glucuronide after absorption of ellagitannins-containing food such as pomegranate, strawberries, red raspberries, walnuts or oak-aged red wine.
Penicillium paneum is a species of fungus in the genus Penicillium which can spoil cereal grains. Penicillium paneum produces 1-Octen-3-ol and penipanoid A, penipanoid B, penipanoid C, patulin and roquefortine C
Penicillium steckii is a species of fungus in the genus Penicillium which produces citrinin, tanzawaic acid E, tanzawaic acid F.
