In this invention, the room temperature impact energy of the material is not greatly changed with the intercritical heat treatment at 660Â° C. to 670Â° C. However, the impact energy of the material is significantly increased by the intercritical heat treatment at 680Â° C. to 750Â° C. for 1 hour to 8 hours.
Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [ 1, 3 ]. In general, foods containing dietary fiber provide magnesium.Magnesium is also added to some breakfast cereals and other fortified foods. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran, lower magnesium content substantially [ 1 ].Selected food sources of magnesium are listed in Table 2.n general, foods containing dietary fiber provide magnesium.

Magnesium: A mineral involved in many processes in the body including nerve signaling, the building of healthy bones, and normal muscle contraction. About 350 enzymes are known to depend on magnesium. Magnesium is contained in all unprocessed foods. High concentrations of magnesium are contained in nuts, unmilled grains, dark-green leafy vegetables, legumes such as peas and beans, and fruit. Magnesium is thus readily available in foods that form the basis of a healthful diet. Magnesium deficiency can occur due to inadequate intake of magnesium, impaired intestinal absorption of the mineral, or excessive loss of it.
