Abstract: The progress on sample preparation techniques for analyzing the limited trace elements in food-stuffs was reviewed.The applications of the high pressure digestion (HPD), microwave digestion (MD), routine preparation techniques such asashing and digestion, low-temperature ashing, acid extraction and pre-concentration complexing extraction, ion exchange resin,chelating resin for the analysis of limited trace elements in food-stuffs were reviewed. Special attention was given to microwavedigestion technique and its hyphenation with AAS, ICP-AES, AFS. The devoloping trend of the sample preparation techniquesfor analysis of the limited trace elements was also discussed.

Key words: food-stuffs, limited trace elements, sample preparation techniques, review
