<p>Potatoes are a crucial food crop, and low-temperature storage is commonly used to preserve their quality over extended periods. However, a key challenge with this method is cold-induced sweetening, which raises reducing sugar levels. In the potato processing industry, reducing sugar concentration is a critical quality indicator, as high levels can negatively impact the color and taste of fried products through the Maillard reaction, leading to undesirable browning and the formation of harmful acrylamide. Therefore, developing a simple, rapid method to measure glucose levels in potato tubers is of significant interest. This study introduces a dipstick-based technique for quick glucose estimation in potatoes. The method is low-cost, user-friendly, and compatible with common chemicals and biochemicals, making it highly suitable for field or on-site testing at processing plants. The paper strip sensing platform enables passive liquid transport and delivers rapid results, providing a practical tool for potato farmers and small processing units. By facilitating timely glucose level assessment, the method can help reduce transportation expenses and minimize crop rejection due to excessive reducing sugars. This research offers a promising solution for improving potato quality management through a more efficient and reliable glucose measurement approach.</p>
