In a 100-gram serving, maize kernels provide 86 calories and are a good source (10–19% of the Daily Value) of the B vitamins, thiamin, niacin (if freed), pantothenic acid (B5) and folate. Maize has suboptimal amounts of the essential amino acids tryptophan and lysine , which accounts for its lower status as a protein source. [109]
Mielie meal, also known as mealie meal or maize meal, is a relatively coarse flour (much coarser than cornflour or cornstarch) made from maize [1] or mealies in Southern Africa. It was originally brought to Africa from the Americas by the Portuguese. [2] Its etymology is uncertain, and may be from the Portuguese milho, or the Afrikaans mielie ...
According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child. This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [4] with the exception of the USA ...
For reference, each kilogram of body fat is roughly equivalent to 32,300 kilojoules of food energy (i.e., 3,500 kilocalories per pound or 7,700 kilocalories per kilogram). Recommended daily intake. Many countries and health organizations have published recommendations for healthy levels of daily intake of food energy.
Table of food nutrients. The tables below include tabular lists for selected basic foods, compiled from United States Dept. of Agriculture ( USDA) sources. Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1]
The energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density . A biofuel is a fuel produced from recently living organisms. Biofuels include bioethanol, an alcohol made by fermentation —often used as a gasoline ...
Corn kernels are the fruits of maize. Maize is a grain, and the kernels are used in cooking as a vegetable or a source of starch. The kernels can be of various colors: blackish, bluish-gray, purple, green, red, white and yellow. One ear of corn contains roughly 800 kernels in 16 rows. One hundred bushels of corn can contain upwards of 7,280,000 ...
Quality Protein Maize. Quality Protein Maize (QPM) is a family of maize varieties. QPM grain contains nearly twice as much lysine and tryptophan, amino acids that are essential for humans and monogastric animals but are limiting amino acids in grains. QPM is a product of conventional plant breeding (i.e., it is not genetically modified) and an ...
