The sensing needs for the fresh produce industry can be split into two primary stages: during maturation in the field, also referred to as Precision Farming, and during storage and transport of the produce, or Postharvest Storage. This work seeks to improve the accuracy and reliability of commercially available electrochemical and spectroscopic sensors tailored to the sensing needs of the fresh produce industry. For electrochemical

One of six IDRC 17 Student award recipients, Ryan Lerud is in the PhD programme at Portland State University, being co-advised by Peter Moeck of the Physics Department and Shankar Rananavare of the Chemistry Department. Ryan has been using multivariate statistics to develop a NIR/Vis Portable Fruit Quality Meter as part of his Masters thesis and on-going internship with Felix Instruments, Camas, WA. In this article, Ryan discusses instrument design, the impact that design has on fluctuating temperature and voltage and the effect of the latter on model performance.

Near infrared spectroscopy is a routine measurement and analysis tool for both liquid and solid samples in a wide variety of industries and locations, both process and laboratory. For process measurements analyzer, validation is a key component of a complete measurement system. This short article will describe an automated validation system suitable for near infrared process analyzers.
