Characterization of domestic onion wastes and bulb ( Allium cepa L . ) : fatty acids and metal contents

  title={Characterization of domestic onion wastes and bulb ( Allium cepa L . ) : fatty acids and metal contents},
  • Abdul-Hammed
  • Published 2013
Different parts of onion bulb that constitute to waste were characterized for their nutritive value using standard methods. Proximate analysis of the samples revealed that protein (8.76%) and ash (11.46%) was highest in top-bottom part, carbohydrate (66.12%) in outer scale, fat (15.71%) and fiber (26.84%) was highest in outer scale part while highest amount of moisture (9.21%) was reported in top-bottom part. X-ray spectrometry revealed that the outer scale had the highest level of calcium (3… CONTINUE READING
