Question 1
|
Grain dimension and 1000-grain
weight are measures of what quality characteristic of paddy?
|
||
Question 2
|
The purity of paddy is determined
by the amount of __________ present in the sample.
Check all that apply. |
||
Question 3
|
The optimum moisture content
of paddy prior to milling is 20-24%.
|
||
Question 4
|
The oven drying method provides
the most reliable measure of moisture content?
|
||
Question 5
|
Measuring grain dimension
to test the varietal purity of a sample is necessary because having a
mixture of varieties in a sample __________?
Check all that apply. |
||
Question 6
|
If the 1000-grain weight
of a sample is lower than the published figure for that variety, it may
mean that the sample has a large proportion of immature grain.
|
||
Question 7
|
'Yellowing' is caused by
over-exposure of the paddy to wet environmental conditions before it is
dried. This results in a combination of microbiological and chemical activity
that overheats the grain and can cause fermentation.
Fermented grains are undesirable because |
||
Question 8
|
Not all published national
standards for paddy use the same set of characteristics.
