Quality characteristics of milled rice

The quality characteristics of milled rice are classified both physically, and chemically.
Review the following terms before reading about physical and chemical characteristics of milled rice:
· Paddy or rough rice = similar term for paddy, or rice retaining its husk after threshing
· Brown rice or husked rice = paddy from which the husk has been removed
· Milled rice = rice after milling which includes removing all or part of the bran and germ from the husked rice
· Head rice = milled rice with length greater or equal to three quarters of the average length of the whole kernel
· Large brokens = milled rice with length less than three quarters but more than one quarter of the average length of the whole kernel
· Small brokens or "brewers rice" = milled rice with length less than one quarter of the average length of the whole kernel
· Whole kernel = milled rice grain without any broken parts
· Milling recovery = percentage of milled rice (including brokens) obtained from a sample of paddy.
· Head rice recovery = percentage of head rice (excluding brokens) obtained from a sample of paddy.
