The purpose of this study was twofold: (a) to identify the most frequent ۴-word lexical bundles and (b) to analyse the functions these lexical bundles may serve. To those ends, a corpus of ۴,۶۵۲,۴۴۴ in Food Science and Technology (hereafter FST Corpus) was developed, using ۱,۴۲۱ research articles (RAs) across ۳۸ Food Science and Technology (FST) journals. Setting frequency and range as two criteria, we used AntConc to identify the most frequent lexical bundles. We also used Hyland’s (۲۰۰۸b) functional taxonomy to analyse the functions of the lexical bundles. The results of frequency and range showed ۱۵۳ lexical bundles in FST Corpus. Functional analysis of the lexical bundles revealed ۸۶ text-oriented, ۶۳ research-oriented, and four participant-oriented lexical bundles, suggesting the central role text-oriented functions may play in FST. Implications for the explicit instruction of lexical bundles, for graduate students in FST, and for EAP curriculum developers and materials producers are discussed.
