Abstract

As a gluten‐free cereal with high nutritional properties, pearl millet [Pennisetum glaucum (L.) R. Br.] has been increasingly regarded as an alternative dryland resilient food crop with enriched grain nutritional value. This paper explores the potential of single‐kernel near‐infrared (SKNIR) spectroscopy combined with multivariate analysis for rapid and non‐destructive evaluation of protein, moisture, fat, fiber, and ash contents of pearl millet grains. Samples harvested from two consecutive years (2021 and 2022) were evaluated under dryland and irrigated conditions in Kansas State University, Agricultural Research Center, Hays (ARCH), KS and were analyzed using SKNIR and conventional laboratory methods. Model calibrations were developed using partial least squares regression. Results showed satisfactory performance of models with standard errors cross‐validation of 1.04%, 0.17%, 0.39%, 0.21%, and 0.16%, respectively, for protein, moisture, fat, fiber, and ash content. The findings suggest that SKNIR can be a potential tool for high‐throughput pearl millet composition screening efficiently, which will assist breeders and grain processors to optimize grain properties and enhance the grain quality and products.

利用单核近红外光谱对珍珠粟[Pennisetum glaucum (L.) R. Br.]成分进行非破坏性鉴定

珍珠粟[Pennisetum glaucum (L.) R. Br.]是一种无麸质谷物，具有很高的营养价值，越来越多的人将其视为具有丰富谷物营养价值的旱地抗逆粮食作物。本文探讨了单核近红外光谱（SKNIR）与多元分析相结合，快速、无损地评估珍珠粟谷物蛋白质、水分、脂肪、纤维和灰分含量的潜力。连续两年（2021 年和 2022 年）收获的样品在堪萨斯州海斯市堪萨斯州立大学农业研究中心（ARCH）的旱地和灌溉条件下进行了评估，并使用 SKNIR 和传统实验室方法进行了分析。使用偏最小二乘回归法进行了模型校准。结果表明，模型的性能令人满意，蛋白质、水分、脂肪、纤维和灰分含量的标准误差交叉验证分别为 1.04%、0.17%、0.39%、0.21% 和 0.16%。研究结果表明，SKNIR 可以作为一种潜在的工具，有效地进行高通量珍珠米成分筛选，从而帮助育种者和谷物加工者优化谷物特性，提高谷物品质和产品。
