摘　　要：主要研究湿热处理对蜡质玉米淀粉消化性影响,通过测定不同处理条件下快消化淀粉,慢消化淀粉和抗性淀粉含量以评价其消化性。研究结果表明,随水分含量、处理温度升高和处理时间延长,蜡质玉米快消化淀粉含量显著下降,而慢消化淀粉和抗性淀粉含量明显上升。Impact of heat-moisture treatment （ HMT ） on digestibility of waxy corn starch in their gelatinized states were studied. Digestibility was evaluated by determining rapidly digestible starch, slowly digestible starch, resistant starch of waxy corn starch after HMT. Results show that the content of rapidly digestible starch dramatically decreased, the content of slowly digestible starch and resistant starch markedly increased when the water content, temperature and time of HMT increased.
