In Example 7.6 we found that an analysis for the inorganic ash content of a breakfast cereal required a sample of 1.5 g to establish a relative standard deviation for sampling of 2.0%. How many samples are needed to obtain a relative sampling error of no more than 0.80% at the 95% conhdence level ... 

Bohman and colleagues described a reverse-phase HPLC method for the quantitative analysis of vitamin A in food using the method of standard additions. In a typical example, a 10.067-g sample of cereal is placed in a 250-mL Erlenmeyer flask along with 1 g of sodium ascorbate,... 

The substitution pattern of arabinosyl side chains in AX from cereal flours and bran, based on the structural analysis of ohgomer fragments produced by xylan-degrading enzymes of known mode of action, was described by several authors [60-63], and various structural models were created [39,60]. fii a recent study [64] on the fine structure of wheat flour AX, a method was...

A homogenized sample of cereals, vegetables, fruits or potatoes (10-20 g) is extracted with an organic solvent such as acetone and methanol. After filtration, the extract is concentrated to about 20 mL by rotary evaporation below 40 °C. The residue is transferred with 5% sodium chloride (NaCl) aqueous solution and partitioned twice with n-hexane. The n-hexane extracts are dried with anhydrous sodium sulfate and subjected to a Florisil column chromatographic cleanup procedure. The eluate from the Horisil column is concentrated to dryness and the residue is dissolved in an appropriate amount of acetone for analysis by GC/NPD. ...

The reasons for mercury pesticide poisoning deserve especially close analysis. OMPs were detected not only in cereals where they could be found since they were used, but also in fish products. We must keep in mind that according to existing public health standards, in principle, granosan (active ingredient ethyl mercury chloride), and especially OMPs (in the mixtures mercury benzol and mercury hexane, the active ingredient is also ethyl mercury chloride), presence in food products is banned [5]. Therefore, the notation exceeds MPL is not appropriate. 

Across Europe the relative significance of organic foods within different food groups varies. The most recent comprehensive analysis of these patterns is provided by Hamm and Gronefeld (2004). In the EU as a whole, the most significant share of organics (by volume) in total consumption is for cereals...

Diclofop-methyl is an early post-emergence herbicide applied to cereals, oil seeds and a variety of other crops for the control of annual grasses. Both Diclofop-methyl and its hydrolysis product, diclofop, are herbicidal [200] therefore, analysis for Diclofop-methyl in soil includes the determination of both chemicals.
