The effect of growth temperature on gelatinization properties of barley starch

The effects of growth conditions on the propel ties of barley starch were s tudied with the two-rowed malting barley cultivars ''Kustaa" and ''Kymppi" field-grown in Finland during a cold summer and a normal summer. In both cu ltivars, the growth conditions had an effect on the composition and gelatin ization behaviour of both small and large granules. In the starches from th e cold summer, the lipid content and gelatinization peak temperatures were lower, the gelatinized starch also being more easily hydrolysed by alpha-am ylase.
