• Recap Standardization
• A typical Supply Utilization Account can contain
  information for up to 1,500 commodities.
• While this is useful for a comprehensive picture
  of the a countrys food supply, the amount of
  data is unmanageable and difficult for
  practitioners and policy makers to analyse.
• The solution is to reduce the list of
  commodities captured within the SUA to a shorter,
  standardized, commodity list and presented in
  Food Balance Sheet format.
• Standardization is the process of converting
  original quantities in the SUA back into their
  primary commodity equivalent
• For example, flour of wheat back into the
  equivalent wheat quantity or skimmed cow milk
  back into the equivalent whole cow milk quantity.

• Step 1
• Reduce the list to the originating commodities.
  Sum the calorie and nutrient values of derived
  and origin commodities.

Step 2 The Input to derived commodities are
subtracted from Processing in the origin
commodity. Production of derived commodities is
not converted back, to avoid double counting.

Step 3 For all other SUA elements in derived
commodities, quantities are converted back to
their origin commodity using the reciprocal of
the extraction rate.

Standardization example Wheat, Other Cereals,

Example Imports of Flour of Wheat soft back to
Wheat soft Extr. rate of Wheat soft to Flour of
Wheat soft 80 Reciprocal 1 / 0.8
1.25 Imports of Flour of wheat soft 45 1.25
56 Imports of Wheat soft 400 Total import of
Wheat soft (including derived commodities) 456

• Step 3
• For all other SUA elements in derived
  commodities, quantities are converted back to
  their origin commodity using the reciprocal of
  the extraction rate.

derived commodities) 44

• Step 3
• For all other SUA elements in derived
  commodities, quantities are converted back to
  their origin commodity using the reciprocal of
  the extraction rate.
