Abstract

In this research, bitter and sweet Lupin (Lupinus albus L.) seeds were used in bulgur production. The proximate chemical compositions and the contents of phytic acid, mineral, amino acid and fatty acid of raw material and processed lupin seeds as bulgur were determined. The sensory properties of bulgur samples were also researched. Bulgur process decreased ash, fat and phytic acid content of lupin seeds while significant increase (p < 0.05) was observed in protein content of bulgur compared with lupin seeds. Phytic acid losses in bitter and sweet lupin bulgurs were found as 18.8% and 21.3%, respectively. Generally sweet lupin seeds/bulgurs showed rich essential amino acids composition than that of bitter seeds/bulgurs. Linoleic and linolenic acid content of the lupin was negatively affected by bulgur process. Bitter lupin bulgur received lower scores in terms of taste, odor and overall acceptability than sweet lupin bulgur in sensory evaluation. Sweet lupin bulgur can be used as new legume-based product with high nutritional and sensorial properties.

Keywords: Amino acid; Bulgur; Fatty acid; Lupin; Mineral; Phytic acid.
