Applications and Properties:
Nutritional:Peanuts consisting of 20 to 30% protein, 5 to 15% carbohydrate, and 40 to 50% oil or fat,contain the important B vitamins, B1, B2, and B3. Niacin, vitamin B3, is extraordinarily plentiful with 1 ounce registering 3.80 mg., while folic acid measures in at a whopping 41.2 mcg.
Medicinal Uses:Before 500 BCE peanuts had been brought to Mexico. There the Aztecs cultivated peanuts as a medicine.
Before 500 BCE peanuts had been brought to Mexico. There the Aztecs cultivated peanuts as a medicine. From the Log of Christopher Columbus translated by Robert H. Fuson, Friar Bernardino de Sahagun describes the Aztec marketplace medicine seller who was considered a "knower of herbs, a knower of roots, a physician." The Aztecs used ground peanuts mixed with water to cure fever.
Safety and Toxicity:
Of greatest concern is possible contamination of damaged or spoiled seeds with the teratogenic, carcinogenic aflatoxins. Two principal toxins, aflatoxins B, and G, and their less toxic dihydro derivatives, aflatoxins B2 and G2 are formed by the aflatoxin producing moulds (Aspergillus flavus et al). Prevention of mould growth is the mainstay, there being no satisfactory way to remove the toxins from feed and foods (however, peanut oils are free of aflatoxins because of alkaline processing). LD50 for aflatoxin for sensitive organisms may be less than 1 mg/kg body weight. "Aflatoxin B1 appears to be the most potent hepatocarcinogen known." Rats receiving only 15 ppm aflatoxin in the diet have high cancer incidence (NAS, 1973). Arachin, with 4 antigens and conarachin with 2 antigens are also reported.
