Effect of harvesting periods on the morphology and physico‐chemical properties of trifoliate yam starches

Trifoliate yam starches from white and yellow cultivars were isolated and characterized by SEM, granule size analysis, pasting properties and swelling characteristics at different harvesting periods were studied. The starch yield ranged from 5.09 to 12.07%. White trifoliate yam had the highest starc...

Description
Summary:Trifoliate yam starches from white and yellow cultivars were isolated and characterized by SEM, granule size analysis, pasting properties and swelling characteristics at different harvesting periods were studied. The starch yield ranged from 5.09 to 12.07%. White trifoliate yam had the highest starch yield at 9 months and this was significantly different (p
