Overview of Different Milk and Milk Products Contaminant Detections by Biosensors

Abstract

Food diseases and allergies are one of the important causes having major impact on health of the world population. Being one of the basic needs of nutrition, milk and milk products are important types of packed foods which are consumed by the modern world population. Milk sources get contaminated due to different sources like pesticide residues, heavy metals, and aflatoxin during the process of cattle feeding, pre-processing, and improper handling during post processing period. Therefore, there is a need of the society to have a more accurate, fast in response, durable and stable analytical device to detect different milk contaminants in packed milk and milk products. Current development in biosensors provides new hope to achieve the goal of milk contaminants detection more precisely and accurately. Hence the basic inclination behind this paper is to study the recent developments in different types of biosensors used in dairy industry and find out future prospective in biosensor development for milk contaminants. In this survey paper we have studied 26 research articles on Biosensor detection techniques used to detect milk contaminants like Urea, Antibiotics, and Metal ions with their different design parameters and implementation strategy. The detection limit analysis of different methods is recorded in the view of deciding the future research path in each of the methods. In future, combination of nanotechnology with electrochemical biosensors and optical biosensors with some modifications can provide highly sensitive, rapid, potable and low-cost biosensors for detection of milk contaminant.
