Main Article Content
บทคัดย่อ
บทความปริทัศน์นี้มีวัตถุประสงค์เพื่อนำเสนอภาพรวมของความก้าวหน้าและการพัฒนาเทคโนโลยีที่ใช้ในการตรวจติดตามคุณภาพของเมล็ดธัญพืชในระหว่างการเก็บรักษาหลังการเก็บเกี่ยว โดยมีเนื้อหากล่าวถึงปัจจัยเสี่ยงสำคัญที่ส่งผลต่อการเสื่อมสภาพของเมล็ด ได้แก่ อุณหภูมิและความชื้นเมล็ด, แมลงศัตรูในโรงเก็บ และเชื้อรา พร้อมทั้งให้รายละเอียดของระบบตรวจติดตามสมัยใหม่ที่อาศัยโครงข่ายเซนเซอร์เพื่อวัดค่าปัจจัยเหล่านี้แบบเวลาจริง ข้อมูลที่ได้จากระบบดังกล่าวสามารถถูกนำมาใช้ประเมินความเสี่ยง เพื่อช่วยในการตัดสินใจใช้มาตรการแทรกแซงเพื่อควบคุมและ/หรือยับยั้งปัญหาที่สร้างความเสียหายต่อเมล็ดอย่างมีประสิทธิภาพ ซึ่งจะช่วยลดการสูญเสียคุณภาพของผลผลิต และยังเป็นประโยชน์ต่อการจัดการเมล็ดธัญพืชอย่างยั่งยืน
This review article provides an overview of the advances and developments in technologies used for monitoring the quality of cereal grains during post-harvest storage. It discusses the key risk factors that contribute to grain deterioration, including temperature and moisture content of the grains, storage insects, and fungi. Furthermore, it details modern monitoring systems that use sensor networks to measure these factors in real-time. The data obtained from such systems can be used to assess risks, helping to inform decisions on effective intervention measures to control and/or prevent problems that cause damage to the grains. This, in turn, helps to reduce losses in product quality and is also beneficial for the sustainable management of cereal grains.
