Abstract

Sustainable development of the agricultural industry, in particular, the production of milk and feed for farm animals, requires accurate, fast, and non-invasive diagnostic tools. Currently, there is a rapid development of a number of analytical methods and approaches that meet these requirements. Infrared spectrometry in the near and mid-IR range is especially widespread. Progress has been made not only in the physical methods of carrying out measurements, but significant advances have also been achieved in the development of mathematical processing of the received signals. This review is devoted to the comparison of modern methods and devices used to control the quality of milk and feed for farm animals.

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. The constant increase in the consumption of milk and milk-containing food products requires the improvement of the methods of express control of the composition and quality of the milk produced. To ensure product quality control, farms are increasingly using high-tech express analysis systems, which are gradually replacing the classic, expensive invasive chemical methods. The quality and volume of dairy products produced depend on the composition and balance of the feed consumed by animals. In this regard, special attention is paid to the control of feed for farm animals. The focus of the review is aimed at comparing various analysis methods, instruments, and their prototypes operating in the visible, near, and middle infrared regions
