Abstract

The cultivation elevation of potatoes plays a crucial role that influences starch quality. Little is known on the impact of varying altitudes on starch quality. Therefore, this new study analyzed the starch attributes of the Median?s potato variety (Solanum tuberosum L.) cultivated at three distinct altitudinal zones: lowlands, midlands, and highlands. The objective was to elucidate the impact of these varying altitudes on the chemical composition, functional qualities and pasting behavior of starch derived from the Median?s cultivar. Utilizing a randomized block design with quadruplicate trials, the data was subjected to one-way ANOVA and Duncan?s Multiple Range Test, at a 5% significance threshold. The results show that highland and midland plantings yielded a higher starch production. The cultivation altitude had a significant influence (p < 0.05) on several chemical parameters of the starch, including its moisture, protein, lipid content, total starch, amylose, ash and phosphorus contents. The functional properties, such as swelling volume, solubility, water and oil absorption capacities, syneresis, gel strength, and colors (a*, b*, L* values) also exhibited significant variance with altitude. Furthermore, pasting qualities also were altered by the altitude of potatoes cultivation. X-Ray Diffraction (XRD), particle size analysis, granule morphology via microscopy and Fourier Transform Infrared Spectroscopy (FTIR), revealed significant differences (p < 0.05) across starches from different altitudes, confirming the influence of environmental conditions on starch quality and its functional properties. These results provide valuable recommendations for customizing potato farming methods to enhance starch yield and their applications in various food production sectors..

不同海拔地区的栽培对马铃薯（Solanum tuberosum L.）淀粉中间体的化学、功能和糊化特性的影响

马铃薯的种植海拔对淀粉质量有着至关重要的影响。人们对不同海拔高度对淀粉质量的影响知之甚少。因此，这项新研究分析了在三个不同海拔高度地区（低地、中地和高地）种植的马铃薯品种（Solanum tuberosum L.）的淀粉属性。目的是阐明这些不同海拔高度对从 Median's 栽培品种中提取的淀粉的化学成分、功能品质和糊化性能的影响。采用随机区组设计和四重复试验，对数据进行了单因素方差分析和邓肯多重范围检验，显著性阈值为 5%。结果表明，高原和中原地区种植的淀粉产量较高。种植海拔对淀粉的几个化学参数有显著影响（p < 0.05），包括水分、蛋白质、脂质含量、总淀粉、直链淀粉、灰分和磷含量。功能特性，如膨胀体积、溶解性、吸水和吸油能力、滞后性、凝胶强度和颜色（a*、b*、L* 值）也随海拔高度的变化而有显著差异。此外，马铃薯种植海拔高度也会改变粘贴质量。X 射线衍射（XRD）、粒度分析、显微镜下的颗粒形态以及傅立叶变换红外光谱（FTIR）显示，不同海拔高度的淀粉之间存在显著差异（p < 0.05），这证实了环境条件对淀粉质量及其功能特性的影响。这些结果为定制马铃薯种植方法以提高淀粉产量及其在各种食品生产领域的应用提供了有价值的建议。关键词：栽培海拔栽培品种栽培方法功能特性淀粉质量
