Vomitoxin

Abstract

Vomitoxin or deoxynivalenol (DON) is one of the tricothecenes (mycotoxins) which comprise a large group of protein synthesis inhibitors. These mycotoxins are also powerful immunosuppressants which may predispose animals to other disease. Vomitoxin is the most commonly found trichothecene in moldy corn, but a number of other biologically active trichothecenes are produced by the species of the fungus Fusarium . The prognosis for recovery from vomitoxin mycotoxicosis is excellent once an animal is removed from the contaminated food source.

Optimization of yield and properties of silken tofu from soybeans.

“…The effects of heating a macerated unfiltering slurry was compared with samples that were heated for 3 min after cold filtering in line with the traditional Chinese method (Shurtleff & Aoyagi, 1979). Analysis of the resulting milks showed that the conversion of soybean protein into the solubilized form in milk was a little more effective with the hot extraction (89.8% recovery) compared with the cold (83.2%), and more solids were removed in the hot extraction (75.6% compared with 66.1%).…”

“…At the higher temperature, a more rapid aggregation and precipitation of the 7s protein may occur and reduce water retention; whereas at temperatures below 70°C the smaller proteins may have limited denaturation and are able to move more freely and so not be incorporated in the tofu. The coagulation temperature used in the traditional method is 75430°C (Shurtleff & Aoyagi, 1979) probably evolved from consideration of the quality since greater yields are obtained at lower temperatures.…”

“…A preparation method that involves heating the macerated slurry prior to filtering (Watanabe et al, 1964) is compared with the traditional cold filtering technique (Shurtleff & Aoyagi , 1979).…”
