The present study has identified several properties relevant to agreater understanding of starch isolated from a Chinese chickpeacultivar compared with corn starch. During gelatinization, the starchgranules were extensively swollen (by approximately 200e300%)and the granular structure was disrupted with amylose leaching outbecause of excess heat, resulting in the formation of a gel matrix. Ahigh amylose content is important to obtain afirm starch gel. Duringgelatinization, a sudden increase in both the G0and G00valuesoccurred above 60C and further heating reduced these values.Cooling could enhance the G0value of starch gel. In addition,chickpea starch showed a lower rate of hydrolysis than corn starchin vitro, indicating a higher resistance to a-amylase digestibilityduring retrogradation. The present study has demonstrated thatchickpea starch may be potentially useful as a nutritional source ofenzyme-resistant starch and provides useful information for foodindustries using chickpea seeds. Additional studies are required todetermine the applicability of chickpea starch for producing resistant starch and other types of functional foods.
