Study on yield and characteristics of starch from different varieties of sweetpotato
In this study,the yields and characteristics of 25 sweetpotato varieties were studied,including yields of tubers,starch contents,ratio of amylopectin content to amylose content (hereafter called A/A ratio),and pasting characteristics of respective sweetpotato starch.The results showed that the yields of tubers and starch were 14.62 ～41.64 t/hm2 and 4.06～9.66 t/hm2,respectively,the highest yield of tuber was Shangshu 19 and the highest yield of starch was Yushu 1.The A/A ratio ranged from 5.63％ to 7.72％,the highest given by Yunshu 271,and the lowest given by Shangshu 133-2.The gelatinization temperatures ranged from 62.5 ℃ to 77.0 ℃,the highest given by Yushu 1 and the lowest given by Nanshu 017.The peak viscosities and setback values were 2 056～2 936 mPa·s and 706 ～ 1 113 mPa·s,respectively.The highest was obtained from Ningshu S10-1,while the lowest was obtained from Jinong 304.The range of bread down values was 991～1 598 mPa·s,with the highest given by Ningshu S10-1 and the lowest given by Yanshu 26.
