Efficient and accurate determination of grain moisture content even with advanced nondestructive techniques, remains a challenge due to complex water-retaining biological structures and hierarchical composition and geometry of grains that affect measurement interpretation and require specific grain-dependent calibration. We review (1) the primary factors affecting permittivity measurements used in practice for inferring moisture content in grains; (2) develop novel methods for estimating critical parameters for permittivity modeling including packing density, porosity, water binding surface area and water phase permittivity and (3) represent the permittivity of packs of grains using dielectric mixture theory as a function of moisture content applied to high moisture corn (as a model grain). Grain permittivity measurements are affected by their free and bound water contents, chemical composition, temperature, constituent shape, phase configuration and measurement frequency. A large fraction of grain water is bound exhibiting reduced permittivity compared to that of free water. The reduced mixture permittivity and attributed to hydrophilic surfaces in starches, proteins and other high surface area grain constituents. The hierarchal grain structure (i.e., kernel, starch grain, lamella, molecule) and the different constituents influence permittivity measurements due to their layering, geometry (i.e., kernel or starch grain), configuration and water-binding surface area. Dielectric mixture theory offers a physically-based approach for modeling permittivity of agricultural grains and similar granular media.<\/jats:p>","DOI":"10.3390\/s22062083","type":"journal-article","created":{"date-parts":[[2022,3,9]],"date-time":"2022-03-09T01:50:53Z","timestamp":1646790653000},"page":"2083","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Dielectric Measurement of Agricultural Grain Moisture\u2014Theory and Applications"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3804-8785","authenticated-orcid":false,"given":"Scott B.","family":"Jones","sequence":"first","affiliation":[{"name":"Department of Plants, Soils, and Climate, Utah State University, Logan, UT 84322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4926-0060","authenticated-orcid":false,"given":"Wenyi","family":"Sheng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Smart Agriculture Systems, China Agricultural University, Ministry of Education, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dani","family":"Or","sequence":"additional","affiliation":[{"name":"Division of Hydrologic Sciences, Desert Research Institute, Reno, NV 89512, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Balendres, M.A.O., Karlovsky, P., and Cumagun, C.J.R.
