Abstract:
The purpose of this study was twofold: (a) to identify the most frequent 4-word
lexical bundles and (b) to analyse the functions these lexical bundles may serve.
To those ends, a corpus of 4,652,444 in Food Science and Technology (hereafter
FST Corpus) was developed, using 1,421 research articles (RAs) across 38 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 (2008b) functional taxonomy to analyse the functions of the
lexical bundles. The results of frequency and range showed 153 lexical bundles
in FST Corpus. Functional analysis of the lexical bundles revealed 86 textoriented,
63 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.

Following Altenberg, researchers, including McCarthy and Carter (2006), Hyland (2008a, 2008b), Chen and Baker (2010), Byrd and Coxhead (2010), Adel and Erman (2012), Karabacak and Qin (2012), and Alquraishi (2014) have worked on lexical bundles and contributed to the literature in this area.
Hyland (2012) claimed that lexical bundles are important to writers and speakers for three reasons: &quot;(1) their repetition offers users (and particularly students) ready-made sets of words to work with, (2) they help define fluent use and therefore expertise and legitimate disciplinary membership, (3) they reveal the lexico-grammatical community- authorized ways of making-meanings&quot; (p.
For instance, lexical bundles must occur in at least 10 texts of the whole corpus of the study in order to be included in the list (Biber &amp; Barbieri, 2007).
Allen (2009) investigated the use of lexical bundles across science research articles which followed Introduction-Methods-Results-Discussion (IMRD) format, focusing broadly on written academic English register.
According to the descriptions provided in Method section, a list of 153 most frequently occurring 4-word lexical bundles in the FST Corpus was finalized after applying frequency and range.
