These compounds are potent antioxidants and are present in high amounts in the CA plant, contributing to its antioxidant properties. Other terpenoids found in CA include centelloside and brahmoside. CA is also a rich source of phenols such as quercetin, kaempferol, and luteolin. The high ...
When pure and dry, it is very stable, but in solution or when moisture is present, the acid and their salts react readily with oxygen. Oxidation is accelerated at both low and high pH values, and is catalyzed by metal ions, particularly for traces of copper ions. The optimum pH for ...
The present invention relates to a novel proton-conducting polymer membrane based on polyazoles which can, because of its excellent chemical and thermal properties, be used in a variety of ways and is particularly useful as polymer elect... G Calundann,MJ Sansone,O Uensal,... - US 被引量...
The cassava cortex is rich in pectin and could be destined for reuse as a new source of this additive, since the disposal of cassava processing residues results in soil and water contamination. Thus, the aim of the present study was to extract pectin from cassava cortex. Initially the flour...
The present invention explains how guava (Psidium Pomiferum), aromatic fruit, from myrtaceous family, contains comparatively with other fruits, a great quantity of ascorbic acid or Vitamin C (202 milligrams per 100 grams of fruit); nevertheless, up until now, guava has not been an obtention ...
Natural sparkling guava wine: volatile and physicochemical characterization/Espumante natural de goiaba: caracterizacao volatil e fisico-quimica The products of glycidol reaction, 1-monocaproin (hexanoic acid product, HAP), HA, glycidol, and a coarse material (mixture of all), were characterized by...
Stearic acid is naturally present in the glycerides of animal fats and most vegetable oils. Reported found in fresh apple, banana, Vitis vinifera L., melon, tomato, ginger, blue cheeses, cheddar cheese, Swiss cheese, feta cheese, buttermilk, raw fatty fish, raw lean fish, raw shrimp, grape...
DefinitionA solid carboxylic acid present in fats and oils as the glyceride. Production MethodsStearic Acid occurs in many animal and vegetable fats and oils, but it is more abundant in animal fat (up to 30 %) than vegetable fat (typically < 5 % ) . The important exceptions are cocoa but...
Among the 11 detected phenolic acids, sinapic acid (16) (13 mg/g) was found to be the predominant phenolic compound in guava leaf extracts followed by syringic acid (7.4 mg/g, 5); 4-hydroxy benzoic acid (5.75 mg/g, 1); ferulic acid (1.64 mg/g, 15); chlorogenic acid (1.4 mg/g...
Gallic acidis a trihydroxybenzoic acid, known to present several pharmacological and biological properties, highlighted by Verma et al., such as: (1)antioxidant activity; (2) antiinflammatory; (3) antimutagenic, and (4) anticancer properties[94–96]. The last property was investigated in various...
