Investigating challenges of near infrared spectroscopy in the cane testing services at South African Sugar Association.

Abstract

The primary routine laboratory analysis of measuring sugar content is conducted using standard refractometry and polarimetry. A secondary method, near infrared (NIR) spectroscopy, offers various benefits and limitations and is well established to monitor the quality of raw sugarcane received by sugar mills for pricing. The perceived problem is that Cane Testing Services has been testing using traditional analytical chemistry methods performed by different individuals utilising various instruments and chemicals. NIR spectroscopy means analysis is performed by one individual in a short time and no chemicals are needed, which causes potential redundancies in some existing positions. An investigation of the challenges that accompany NIR spectroscopy implementation is required to understand its impact and consequences for the organisation. This study is descriptive in nature; a qualitative research approach using structured interviews therefore gathered data on the challenges of implementing NIR spectroscopy, to provide a description of the technology function, and to make recommendations regarding solutions to the challenges. Five managers and five supervisors at Cane Testing Services were interviewed to collect data. Thematic analysis was conducted to code the data into categories and themes. The study findings identified challenges such as poor communication, NIR spectroscopy being a secondary method, organisational structure, and fear of change. The conclusions of this study are that the significant benefits of NIR spectroscopy are environmental safety benefits, cost efficiency, and time saving. Implementation management and personnel reskilling are essential to offset potential job losses.
