Research Process on Composition Characteristics and Application of Trace Elements in Eggs
Eggs are rich in a variety of trace elements and are an important source of essential trace elements for human be-ings.Meanwhile,eggs contain very low level of harmful non-essential trace elements,making them a rare and highly safe nutri-tional food.The level of trace elements in eggs was influenced by various factors and has certain specificity.The characteristic ele-ment fingerprint can be obtained by multi-element analysis,which has important applications in geographical location tracing and classification.This review introduced the composition characteristics of trace elements in eggs,the influencing factors(layer breed,external environmental conditions and feed)of the differences in trace element content in eggs were discussed,which was applied to the geographical information traceability and classification research of eggs.The paper could provide theoretical sup-port and methodological reference for the nutritional health,food safety,traceability and classification of eggs.
