摘　　要：通过分段筛分粉碎,获得不同粒径豆渣,测定其蛋白质、脂肪、可溶性膳食纤维、灰分等化学成分的含量,以及持水力、膨胀力、持油力、水溶性等物理指标。结果表明:M40(粒径40目)、M60(粒径60目)和M80(粒径80目)豆渣的蛋白、脂肪以及灰分、总膳食纤维的含量不具有显著差异性(p>0.05),M150(粒径150目)豆渣的蛋白、脂肪、灰分、总膳食纤维的含量与M40豆渣均具有显著性差异(p<0.05)。随着粒径减小,豆渣中的可溶性膳食纤维呈增加趋势。粒径对豆渣的水溶性、膨胀力、持水力和持油力具有显著性影响。随粒径的减小,豆渣水溶性、膨胀力、持水力先增大后减小,M100(粒径100目)豆渣的水溶性最高,M120(粒径120目)豆渣的膨胀力最大,M80豆渣的持水力最大。豆渣粒径从40目减小到60目时,豆渣的持油力显著性下降。当粒径进一步减小时,豆渣的持油力无显著性差异。Okara with different particle sizes was prepared by subsection screening and grinding.The contents of protein,fat,soluble dietary fiber,ash and the physical indexes such as water holding capacity,swelling capacity,oil holding capacity and water-solubility were determined.The results showed that the contents of protein,fat,total dietary fiber and ash in M40(particle size 40 mesh),M60(particle size 60 mesh)and M80(particle size 80 mesh)of okara did not have significant difference,but the contents of M150(particle size 150 mesh)and M40 of okara had significant difference.The soluble dietary fiber in okara increased with the decrease of particle size.Particle size had significant effect on water-solubility capacity,expansion capacity,water holding capacity and oil holding capacity of okara.With the decrease of particle size,the water solubility,expansion capacity and water holding capacity of okara increased first and then decreased.M100(particle size 100 mesh)of okara had the highest water-solubility,M120(particle size 120 mesh)had the largest swelling force and M80 had the largest oil holding capacity.The oil holding capacity of okara decreased significantly when the size of okara decreased from 40 mesh to 60 mesh.There was no significant difference in oil holding capacity of okara when the particle size was further reduced.
