  • Oxygen radical absorbance capacity

    serch.it?q=Oxygen-radical-absorbance-capacity

    Oxygen radical absorbance capacity (ORAC) was a method of measuring antioxidant capacities in biological samples in vitro. Because no physiological proof in vivo existed in support of the free-radical theory or that ORAC provided information relevant to biological antioxidant status, it was withdrawn in 2012. Various foods were tested using this method, with certain spices, berries and legumes rated highly in extensive tables once published by the United States Department of Agriculture (USDA). Alternative measurements include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay.

  • List of antioxidants in food

    serch.it?q=List-of-antioxidants-in-food

    This is a list of antioxidants naturally occurring in food. Vitamin C and vitamin E – which are ubiquitous among raw plant foods – are confirmed as dietary antioxidants, whereas vitamin A becomes an antioxidant following metabolism of provitamin A beta-carotene and cryptoxanthin. Most food compounds listed as antioxidants – such as polyphenols common in colorful, edible plants – have antioxidant activity only in vitro, as their fate in vivo is to be rapidly metabolized and excreted, and the in vivo properties of their metabolites remain poorly understood. For antioxidants added to food to preserve them, see butylated hydroxyanisole and butylated hydroxytoluene.

  • Açaí palm

    serch.it?q=Açaí-palm

    The açaí palm (, from Tupi-Guarani asaí), Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit (açaí berries or simply açaí), hearts of palm (a vegetable), leaves and trunk wood. Global demand for the fruit expanded rapidly in the 21st century and so the tree is cultivated for that purpose primarily.Euterpe oleracea is mostly native to Brazil, Trinidad and other countries of northern South America, mainly in swamps and floodplains. Açaí palms are tall, slender trees growing to more than tall, with pinnate leaves up to long. The fruit is small, round, and black-purple in color and may be sold as a frozen fruit puree or bottled juice drink with added sugar or other sweeteners.
