    The nutrient components of eight cultivars onion powder produced in Shandong province were analyzed to select the specific varieties for onion processing. The results showed that:The nutrient components including total sugar, protein, and crude fiber had significant differences except ash. The content of total sugar was the highest with the range of 47.29%-69.51%, followed by protein, crude fat, crude fiber and ash. The content of flavonoid was between 76.13mg/100g to 556.63mg/100g, and hydrolyzed amino acid content was between 8.54% to 15.31%. Potassium content in minerals was the highest, followed by P, Ca, Mg, Na, and Fe content was closed to zero. White onion No.2 and red A5 could be exploited as specific processing cultivar, and the onion oil and polysaccaride could be extracted from the former, and A5 could be used as the feed.
