摘要:

【目的】以16个辽宁省地方高粱品种为试验材料,研究不同高粱品种食用品质性状及其相关关系,为筛选优质食用高粱种质资源提供理论依据。【方法】对16个高粱品种籽粒中的直链淀粉、支链淀粉、粗脂肪、粗蛋白和单宁含量进行测定,同时对这些高粱品种的食用品质进行感官评价,利用快速黏度分析仪(rapid visco analyzer,RVA)对高粱淀粉黏滞性进行测定,对其差异性以及各指标间的相关性进行分析。【结果】从营养品质和感官评价分析,矮子白1、红壳棒、锦粱9-2和分枝大红穗获得的综合评分均较高,且适口性、滋味、气味等指标都表现较好。矮子白2和真白粱籽粒中粗脂肪含量较高且与其他品种差异显著,红壳白1、红壳白2和黄壳白中粗蛋白含量较高且与其他品种差异显著,大白高粱1籽粒中的淀粉含量显著高于其他品种,所有品种单宁含量均低于0.5%。高粱米粥的感官综合评分与粗蛋白和单宁含量呈极显著负相关;蛋白质和单宁对高粱适口性和滋味有一定的负向作用;支链淀粉对适口性和冷粥质地有正向作用。粗脂肪含量与冷胶黏度、消减值和峰值时间呈极显著正相关,总淀粉含量与最高黏度和热浆黏度呈正相关,粗蛋白含量与冷胶黏度、消减值和峰值时间呈极显著正相关;直链淀粉与RVA谱的黏度和崩解值呈极显著负相关,而支链淀粉与黏度和崩解值呈极显著正相关。淀粉黏滞性系数与感官评分具有较大的相关性,最高黏度和崩解值的大小与综合评分呈极显著正相关,而峰值时间和糊化温度则与综合评分呈极显著负相关。【结论】RVA谱特征值与食味指标之间存在紧密的联系,可以通过测定RVA谱特征值间接反映高粱米的食味特征。综合考虑食用品质,高粱地方品种矮子白1和红壳棒是较为理想的食用型高粱品种。

Abstract:

【Objective】 In this study, 16 sorghum landraces from Liaoning province were used as experimental materials to study the edible quality traits and the relationships among these traits. 【Method】 Nutritional components of 16 sorghum landraces, including amylose, amylopectin, crude fat, crude protein and tannin content in grains, were determined and the edible qualities of these sorghum landraces were evaluated using sensory evaluation. The viscosity of sorghum starch was measured using a Rapid Visco Analyzer (RVA). The differences and the correlations among indices were analyzed. 【Result】 In terms of nutritional quality and sensory evaluation, the overall score of Aizibai 1, Hongkebang, Jinliang 9-2 and Fenzhidahongsui were higher than the other landraces; the mouthfeel, taste, and smell of these two landraces were also better than the others. The content of crude fat in the grains of Aizibai 2 and Zhenbailiang were significantly higher than in other landraces. Contents of crude protein in Hongkebai 1, Hongkebai 2 and Huangkebai landraces were significantly higher than in the others. Starch content in the grains of Dabaigaoliang 1 was significantly higher than in other landraces. Tannin contents in all landraces were less than 0.5%. The taste value of sorghum porridge was negatively correlated with crude protein and tannin content and protein and tannin had negative effects on mouthfeel and taste. Amylopectin had a positive effect on mouthfeel and cold porridge texture. There was a significantly positive correlation between the content of crude fat and the cool paste viscosity, setback viscosity and peak time. The total starch content was positively related to the peak viscosity and the hot pulp viscosity. The crude protein content was significantly positively correlated with the cool paste viscosity, the setback viscosity and the peak time. Amylose content was significantly negatively correlates to the viscosity level and disintegration value of the RVA spectrum. Amylopectin was significantly positively correlated to the viscosity level and disintegration value of the RVA spectrum. RVA was significantly correlated with taste value. The peak viscosity and break down viscosity were positively correlated with the comprehensive score, while the peak time and pasting temperature were negatively correlated with the taste value. 【Conclusion】 There was a close relationship between RVA spectrum characteristic value and taste index. The taste characteristics of sorghum porridge were indirectly reflected by the RVA spectrum characteristic value. Based on comprehensively considering the edible quality, Aizibai 1 and Hongkebang were the ideal sorghum types.
