Abstract

Background and Aim:Monitoring food quality and safety remain a pressing issue. The intermediate results of the study on the residual amounts of heavy and toxic elements in food products are presented herein. The aim of this study was the determination of heavy metals in milk and fermented milk products from basic farms in the Almaty region, Kazakhstan.Materials and Methods:A total of 120 raw milk samples and 80 cottage cheese samples were analyzed. The milk and cottage cheese samples were subjected to mineralization during the analysis to remove organic impurities and determine the heavy metal concentrations using atomic absorption spectrometry.Results:The contents of cadmium, lead, and arsenic in all raw materials and food products did not exceed the maximum permissible concentrations.Conclusion:The dairy samples showed low contents of cadmium, mercury, lead, and arsenic that did not exceed the allowable concentrations for basic farms in the Almaty region.

Highlights

High-quality and safe food products are essential prerequisites for maintaining food independence in Kazakhstan and represent important tasks of the state policy for healthy nutrition

Summary

Introduction

High-quality and safe food products are essential prerequisites for maintaining food independence in Kazakhstan and represent important tasks of the state policy for healthy nutrition. The level of contaminants in raw food materials has increased by a factor of almost five over the past 5 years. Toxic elements can be found in 90% of commonly studied food products. Heavy metals represent a special group of food contaminants and the influx of heavy metals into the environment has significantly increased recently due to rapid industrialization and the use of new technologies that require heavy metals. The metals can enter raw milk and dairy products through the food chain [3,4]. The likelihood of negative effects of contaminated food products on the health status. The intermediate results of the study on the residual amounts of heavy and toxic elements in food products are presented . The aim of this study was the determination of heavy metals in milk and fermented milk products from basic farms in the Almaty region, Kazakhstan
