The increasing demand for diverse foods and tailored nutrition encourages the development of innovative products, such as bread enriched with cricket powder (CP) or potato protein (PP). This study presents the preparation and analysis of gluten-free breads with CP and PP, focusing on their nutritional value and physical properties. Analytical methods included water activity measurement, bread volume, crumb color analysis, FTIR spectroscopy, low-field NMR relaxometry, and texture profile analysis. Ash content ranged from 0.60 ± 0.03% to 1.16 ± 0.11%, and caloric values ranged from 216.2 to 229.5 kcal/100 g. Water activity remained stable across all samples (0.975-0.976). Crumb color analysis showed the greatest change in CP samples (ΔE = 14.07), while PP had minimal impact (ΔE = 2.15). FTIR spectra revealed increased amide I and II bands, indicating higher protein content. NMR results demonstrated shorter T, T, and T times for CP, suggesting reduced water mobility and a denser structure, while PP samples showed higher values, indicating a looser, more hydrated matrix. Texture analysis confirmed that CP increased firmness and compactness, whereas PP enhanced springiness. These findings suggest that CP and PP can improve the nutritional and structural properties of gluten-free bread, offering valuable alternatives for modern dietary needs.
对多样化食品和定制营养的需求不断增加,推动了创新产品的开发,例如富含蟋蟀粉(CP)或马铃薯蛋白(PP)的面包。本研究介绍了含CP和PP的无麸质面包的制备与分析,重点关注其营养价值和物理特性。分析方法包括水分活度测量、面包体积、面包心颜色分析、傅里叶变换红外光谱法(FTIR)、低场核磁共振弛豫测定法以及质地剖面分析。灰分含量在0.60±0.03%至1.16±0.11%之间,热量值在216.2至229.5千卡/100克之间。所有样品的水分活度保持稳定(0.975 - 0.976)。面包心颜色分析显示CP样品变化最大(ΔE = 14.07),而PP的影响最小(ΔE = 2.15)。FTIR光谱显示酰胺I和II带增加,表明蛋白质含量更高。核磁共振结果表明CP的T1、T2和T2*时间较短,表明水分流动性降低且结构更致密,而PP样品的值较高,表明基质更疏松、水合程度更高。质地分析证实CP增加了硬度和紧实度,而PP增强了弹性。这些发现表明,CP和PP可以改善无麸质面包的营养和结构特性,为现代饮食需求提供有价值的替代选择。
