Background:
The milling of food in agro-industrial products has become an operation of high importance at a
business, academic and research level.
Objective:
This article aims to present the results of a literature review on food milling, with the purpose to identify the
most recent uses, types of mills, and new grinding trends.
Methods:
For this, a research equation was made with the keywords "grinding", "milling" and "food" in Scopus, which
yielded as results 192 articles, 52 which are directly related to food, were analyzed.
Results:
Contributions were found in various types of grinding such as cryogenic grinding, nano-scaled grinding, ultrafine
and superfine grinding.
Conclusion:
The authors highlighted the uses of these types of milling in Agro-industrial products such as nutmeg
(Myristica fragrans), wheat bran (Triticum spp), ginger (Zingiber officinale) and green tea powder (Camellia sinensis),
among others. It is observed that engineering texts dealing with theoretical and analytical food milling operations do not
emphasize the new trends found. As a complementary part of this study, eight patents related to cryogenic grinding in
food were analyzed, identifying uses of this type of grinding in coffee, lipids, lycopene, proteins, grains, and seeds;
Besides, a query was carried out to find out commercial suppliers of cryogenic grinding equipment, in which six
companies from China with their equipment were identified.
