Abstract

The present work was carried out to observe the comparative effectiveness of different chemical treatments in combination with simultaneous thermal treatment on soluble and insoluble dietary fibre ratio to improve functional properties of barley. For this purpose two varieties of barley i.e. Haider-93 and Jau-87 were assessed for their chemical composition mineral non-starch polysaccharides and dietary fibre contents through respective methods. Next both varieties were chemically treated with acid alkaline and consecutive acid-alkaline treatments in combination with thermal treatment. Results of chemical composition revealed that Jau-87 was higher in moisture (11.4) crude fat (2.67) and crude fibre (4.70) whereas Haider-93 exhibited higher ash (2.56) and crude protein content (12.7). Moreover barley was rich source of potassium ranging from 4.77-5.07 g/kg. Likewise main non-starch polysaccharides in barley were arabinoxylan (3.60-3.77) and -glucan (3.65-3.67). Furthermore barley contained more insoluble dietary fibre (12.00-12.40 g/100 g dm) than soluble dietary fibre (4.73-5.70 g/100 g dm). Additionally modification of soluble (1.48) and insoluble dietary fibre (8.71) ratio through extrusion processing was non-significant whilst acid-alkaline treatment showed highly significant results i.e. 771.46 increase in soluble dietary fibre and 53.39 decrease in insoluble dietary fibre It was therefore concluded that chemical treatments alone or in combination with twin-screw extrusion increased soluble dietary fibre. However simultaneous effect of acid and alkaline treatment most effectively increased the solubility of barley.
