Cereal lipids

Modulation of the activities of membrane enzymes by cereal grain resorcinolic lipids.

Resorcinolic lipids, amphiphilic compounds from cereal grains show strong effects upon the activity of membrane enzymes. The concentrations for 50% inhibition of erythrocyte membrane acetylcholinesterase were in the range of 18-90 microM and were dependent on the length of the aliphatic side chain of the homologue and on the modification of hydroxyl groups in the benzene ring. Sulfonation of OH...

Detection Methods for Mycotoxins in Cereal Grains and Cereal Products

Analytical methods for mycotoxins in cereals and cereal-based products require three major steps, including extraction, clean-up (to eliminate interferences from the extract and concentrate the analyte), and detection/determination of the toxin (by using suitable analytical instruments/technologies). Clean-up is essential for the analysis of mycotoxins at trace levels, and involves the use of s...

Trichothecenes in Cereal Grains

Trichothecenes are sesquiterpenoid mycotoxins associated with fusarium head blight (FHB) of cereals, with worldwide economic and health impacts. While various management strategies have been proposed to reduce the mycotoxin risk, breeding towards FHB-resistance appears to be the most effective means to manage the disease, and reduce trichothecene contamination of cereal-based food products. Thi...

Visualizing cereal world

We discuss the basic theory of price indices. These form the basis for the Consumer Price Index in the United States. We note situations which can lead to non-robustness and volatility in several different price indices. An experiment to replace survey-based data with point of sales (POS) scanner data is being carried out. We visually explore the scanner data and conclude that certain aspects o...
