Chemical and Nutritional Studies on Sesamum indicum


Abstract
In this study, the several chemical compositions, which include general components (moisture, fat, protein, sugar, fiber, ash, acid insoluble ash), minor components (sesamol, sesamolin, sesamin), the characteristics of oil (specific gravity, refractive index, iodine value, saponification value, unsaponificable matter, insoluble impurities), fatty acid components (analyzed by GLC), amino acid patterns (analyzed by autoanalyzer), of Korean whole white Sesamum indicum were investigated and were compared with decuticled sesame samples.
The results were summarized as follows:
1) The crude fiber, total ash and acid insoluble ash contents of the decuticled sesame seed and it meal were significantly lower as compared to the whole sesame samples.
2) The specific gravity, refractive index, iodine value, unsaponificable matter and insoluble impurities contents of the whole sesame oil were a eater than the decuticled samples.
3) The fatty acid contents of the whole and decuticled sesame oil were approximatly equal amounts. But unsaturated fatty acid contents of the decuticled sesame oil was significantly lower than the whole sesame oil.
4) The decuticled sasame meal was concentrated higher protein than the whole sasame meal. But amino acid contents of the protein in their was approximatly equal amounts and sesame proteins are found to be rich in methionine, cystine and tryptophan, they are deficient in lysine.
5) The sesamol, sesamolin and sesamin contents of the whole and decuticled sesame oil were approximatly equal amounts.
6) The oxalate and calcium contents of the decuticled sesame seed and its meal were also significantly lower as compared to the whole sesame samples.
