Question

Label Data: Vegetables The following are data from a study looking at 'label' data for a number of vegetables. The first step in the analytical process is to create a homogenized sample. This is done by 'drying' each sample overnight in a 60°C oven, then grinding to a fine powder. The dry homogeneous sample (the SAMPLE) is convenient for performing the remainder of the analyses. Complete the following table. Show all calculations 1) Dry' Veg Dry' Veg Moisture Vegetable Pan Pan+ Veg Vg Veg (SAMPLE) (SAMPLE) Removed Pan + Dry Wt. 503.26 Wt. Wt. 84.44 Broccoli 13.54 *Note: this is the homogenous sample that will be used for further analysis

Explanation / Answer

veg wt(g)

=(pan+veg)-(pan)

dry veg (sample) wt(g)

==(pan+dry veg)-(pan)

dry veg (sample) %

=(dry veg wt/veg wt)*100

moisture removed(%)

=(moisture wt/veg wt)*100

=[(veg wt-dry veg wt)/veg wt]*100

vegetable pan wt(g) pan+veg wt(g) pan + dry veg (wt g)

veg wt(g)

=(pan+veg)-(pan)

dry veg (sample) wt(g)

==(pan+dry veg)-(pan)

dry veg (sample) %

=(dry veg wt/veg wt)*100

moisture removed(%)

=(moisture wt/veg wt)*100

=[(veg wt-dry veg wt)/veg wt]*100

broccoli 13.54 503.26 84.44 503.26-13.54=489.72g 84.44-13.54=70.9g =(70.9/489.72)*100=14.5% =[(489.72-70.9)/489.72]*100=85.5%
