Abstract

The study was conducted to compare the components such as proximate composition, total dietary fiber(TDF) content, acid detergent fiber(ADF) content, lignin, water binding capacity(WBC), amino acid composition and lipid components from brown Job´s tears, dehulled Job´s tears, brown Yeomjoo and bran of Job´s tears. The results from this study are summerized as follows: Total dietary fiber(TDF) content of Job´s tears, brown Job´s tears, brown Yeomjoo and bran of Job´s tears were 2.70%, 3.86%, 4.33% and 13.3 % each. Water-binding capacity(WBC) of TDF and ADF were 2.63±0.02g H₂O/g TDF and 5.89±0.15g H₂O/g ADF each. In amono acids composition of samples, glutamic acid content was the highest and the next was leucine. Chemical score of leucine in dehulled Job´s tears was eery high(189), in contrast lysine was very low(22-23) So lysine was a first limitting amino acid in Job´s tears and Yeomjoo. Neutral lipid contents were 90.89%-96.55%, glycolipid contents were 2.35%-1.48% and phospholipid contents were very low. The major fatty acids of lipid fractions were palmitic acid, oleic acid and linoleic acid.
