Abstract
In this paper,we determined the properties of 6 kinds of rice,and discussed the influence of the rice properties on the retrogradation characteristics of rice noodles.The results showed that the gelatinization degree of rice noodles made from Xinyang hybrid long grain rice with the properties of amylose content 24.40%,gel consistency 34.00 mm,attenuation value 2 130 Pa·s,and retrogradation value 2 650 Pa·s changed from 88.31% before retrogradation to 85.10% after retrogradation for 2 hours,so that the rice noddles had a relative high retrogradation speed and good quality.Therefore,the rice noodes made from rice materials with high amylose content,high gel consistency and high retrogradation value had high retrogradation speed,and short retrogradation time.
