STUDIES ON AMINO ACID AND MINERAL ELEMENT CONTENTS OF SOME HIGH-QUALITY AND SPECIAL RICES IN SOUTH CHINA

Measuring of amino acid(AA) and mineral element content was conducted in the ten high quality rices and special rices The structure of AA was rational The total AA content and each AA content AA varied in different varieties In the special rices, seven essential amino acid content was plentiful and higher than FAO/WHO model content,and the Ca,Fe,Zn,Mn,Mg,P,K,ect mineral elements contents were high,especial in the blood polished glutinous rice Putted forward,eating the special rice could promote nutrition balance and increase body quality The other studies indicated that adding organic fertilizer was an effective measure to increase the mineral elements contents in rice
