Cereal production statistics

The analysis of the food questionnaire did not reveal a statistically significant influence of a single nutritional determinant (milk, meat, fish and cereal products) on the UI. According to our experience, the discriminatory power of a questionnaire is low. For example, 89% of all 805 subjects reported the use of iodinated salt at home (>3 times per week) and consumption of fish (>1 times per week) was reported by 98% of the participants. This is very unlikely, based on previous investigations in Germany (Merges etaL, 1996). 

Finally, 1462 and 2070 analytical results were used, respectively, for raw cereals and cereal products. The resulting mean and other main statistical descriptors of the distribution curves are compiled in Tables 9 and 10. 

The following characterization of starch crops describes maize, potatoes, wheat, and other cereals in more detail. Another significant source for starch is rice. However, cultivation is both technically and traditionally concentrated in Asia, so rice is mainly imported into Europe as food and so far does not play a role as renewable raw material (for rice straw, see Section 4.2.2.4). Table 4.3 gives an overview for selected starch crops in terms of characteristics and production statistics.

Similarly, cereal protein compositions are frequently related to grain or product functionality. Thus, it should be possible to correlate quality with the presence or amount of specific components. Finding such relationships in complex data sets is, however, not simple. Mosleth and Uhlen [85] first used the statistical procedure partial least squares (PLS) regression to identify quality-... 

Quantification of nitrogen incorporated by crop residues is not as straightforward, as no country keeps statistics on their production. My calculations resulted in the most likely total of 3.75 Gt of dry residual phytomass. Cereal straws, stalks, and leaves accounted for % of all residual phytomass, and sugarcane tops and leaves were the second largest contributor. As already explained in chapter 2, substantial inter- and intraspecific variations in nitrogen content result in a rather broad range of the nutrient incorporated annually in crop residues. ...
