Iodine-129 for determining the origin of salinity in groundwater in Pampanga, Philippines.

Assessing groundwater vulnerability from salinity contamination is vital and relevant to meet the increasing demand for freshwater. Iodine-129 (I, half-life = 15.7 million years), a radioisotope of iodine, was used as an environmental tracer for the possible origin of salinization in groundwater (e.

Preferences for groundnut products among urban residents in Ghana.

Background: The present study identifies factors influencing preferences for common groundnut products using information about product perceptions from residents in Ghana's cities collected in 2011. In Ghana, domestically produced groundnuts, processed into a variety of groundnut products, are a vital source of protein and other nutrients.

Results: Response summaries provide insights about the eating frequency of various products, whereas a bivariate ordered probit model identifies factors influencing preferences for groundnut paste and roasted groundnuts.

Diversity of global rice markets and the science required for consumer-targeted rice breeding.

With the ever-increasing global demand for high quality rice in both local production regions and with Western consumers, we have a strong desire to understand better the importance of the different traits that make up the quality of the rice grain and obtain a full picture of rice quality demographics. Rice is by no means a 'one size fits all' crop. Regional preferences are not only striking, they drive the market and hence are of major economic importance in any rice breeding / improvement strategy.

Resveratrol in peanuts.

Peanuts are important dietary food source of resveratrol with potent antioxidant properties implicated in reducing risk of cancer, cardiovascular and Alzheimer's disease, and delaying aging. Resveratrol is a naturally occurring stilbene phytoalexin phenolic compound produced in response to a variety of biotic and abiotic stresses. This paper is a review of trans-resveratrol and related stilbenes from peanuts--their chemical structures, mechanisms for their biosynthesis, and concentrations in comparison with other major food sources.
