Characterization and Antioxidant Activity of Mannans from with Different Molecular Weight.

Polysaccharides were extracted from natural sources with various biological activities, which are strongly influenced by their chemical structure and molecular weight. In this research, mannans polysaccharides were obtained from by ethanol precipitation. The molecular weight of YM50, YM70, and YM90 mannans was 172.

Study on sampling scheme for detecting mycotoxin during wheat storage.

Background: Mycotoxin produced by mould is one of the most serious contamination sources in food security. Safe storage of grain has become more important to control food security. Currently, there is no officially approved or standardized sampling scheme for detecting mycotoxin in grain storage worldwide.

Primary research on sampling scheme for analyzing mycotoxin distribution in wheat and rice fields.

Background: Mycotoxins are among the most severe food contaminants. Deoxynivalenol and aflatoxin contamination are predominant in wheat and rice, respectively. Nowadays, there are no standardized and approved grain-sampling schemes worldwide.
