Research trends in optical spectrum for honey analysis

Abstract

The high demand for genuine honey leads to fraud practices in the market which have disadvantaged top graded genuine honey production. The conventional chemical analysis procedures are usually used to ensure the quality and authenticity of honey. Yet, some drawbacks, such as time-consuming, laborious, invasive and required complex sample preparation, in the chemical approaches make the optical spectrum based honey analysis an advantageous alternative method. This paper reports a comprehensive survey of peer-reviewed articles in honey analysis using spectroscopy techniques. The technologies, features, and preprocessing and prediction methods from the observed articles have been discussed to give an overview about optical spectrum approaches for honey analysis. This paper quickly introduces reseachers to modern honey analysis research.
