白色辣椒属于高价值商品，是掺假的对象，导致质量损失，侵害消费者权益。因此，建立快速、可靠的检测白色胡椒粉掺假的方法势在必行。研究了近红外光谱法定量检测白色辣椒粉中掺伪物（包括全麦粉和玉米粉）的可行性。建立了偏最小二乘（PLS）校正模型。结果表明，校正标准误差（SEC）和预测标准误差（SEP）分别为0.788%和0.920%。
White pepper is a high-value commodity that is a target for adulteration, leading to loss of quality and encroachment on the rights and interests of consumers. Therefore, it is imperative to develop fast and reliable methods for detecting white pepper powder adulteration. The present paper investigated the feasibility of using near infrared (NIR) spectroscopy for quantifying adulteration (including whole wheat flour and corn flour) in white pepper powder. Partial least squares (PLS) calibration models were developed. Results showed that the standard error of calibration (SEC) and prediction (SEP) were 0.788% and 0.920%, respectively.
