NaHCO3对非油炸全麦方便面品质及体外消化特性的影响OA
Effect of NaHCO3 on the Quality and in Vitro Digestion Characteristics of Non-fried Whole Wheat Instant Noodles
为改善全麦非油炸方便面的食用品质,本实验通过复水性测定、质构分析、扫描电子显微镜观察、傅里叶变换红外光谱分析、体外消化模拟及感官评价等方式,系统探讨不同NaHCO3添加量(0％、0.1％、0.2％、0.3％、0.4％、0.5％)对非油炸全麦方便面品质及体外消化特性的影响.结果表明,适量添加NaHCO3可有效提升产品的耐泡性、质构特性、感官品质与微观结构.当NaHCO3添加量为0.2％时,预估血糖生成指数降至最低值(62.68),无规卷曲相对含量为(17.23±0.36)％,亦为最低;蛋白质二级结构中β-折叠比例整体上升,α-螺旋与β-转角占比逐渐降低,蛋白质结构有序性提高.过量添加NaHCO3则会导致非油炸全麦方便面耐泡性下降、微观结构松散,淀粉抗消化性与蛋白质二级结构有序度降低.综合各项品质指标,NaHCO3在非油炸全麦方便面中的最适添加量为0.2％.
To improve the eating quality of whole wheat non-fried instant noodles,this study examined the effects of different levels of NaHCO3 addition(0％,0.1％,0.2％,0.3％,0.4％,and 0.5％)on their quality and in vitro digestion characteristics by measurement of rehydration properties,texture analysis,scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR),in vitro digestion simulation,and sensory evaluation.The results indicated that the appropriate addition of NaHCO3 effectively enhanced the foam resistance,texture characteristics,sensory quality and microstructure of the product.Upon the addition of 0.2％NaHCO3,the lowest estimated glycemic index(eGI)of 62.68,and the lowest proportion of random coil(17.23±0.36)％were observed.The proportion of β-sheet in the secondary structure of proteins generally increased,and the proportions of α-helix and β-turn decreased accordingly,indicating improved structural order of proteins.Excessive addition of NaHCO3 resulted in a decline in the water-holding capacity,microstructural compactness,digestive resistance of starch,and order of protein secondary structure in the noodles.Considering all quality indicators,the optimal addition level of NaHCO3 in non-fried whole wheat instant noodles is 0.2％.
