Establishing a regional baseline map of bioavailable 87Sr\/86Sr is essential for precise traceability. However, the existing large-scale bioavailable Sr isotope map of China has low spatial resolution and uses water as the main sample, making it unsuitable for plant-derived food traceability. This study focused on Anhui, a major agricultural province in China. Based on geological lithology distribution, 149 plant samples were collected across Anhui to construct a fine-scale bioavailable 87Sr\/86Sr map. The map enabled traceability of Anhui\u2019s characteristic plant-derived foods, such as Cha (Camellia sinensis), Mugua (Chaenomeles speciosa), Fengdan (Paeonia ostii), Jiegeng (Platycodon grandiflorum), and Duohua Huangjing (Polygonatum cyrtonema). It provides a basis for food origin traceability in Anhui and supports market supervision of China\u2019s geographical indication (GI) products.<\/jats:p>","DOI":"10.3390\/foods15010033","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T16:19:26Z","timestamp":1766420366000},"page":"33","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Fine-Scale Strontium Isotope Mapping in Eastern China (Anhui Province) and Its Application in Food Traceability"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6517-2965","authenticated-orcid":false,"given":"Mei","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"},{"name":"School of Pharmacy, Anhui University of Chinese Medicine, Hefei 230012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunlu","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojing","family":"Han","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aoyu","family":"Ren","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"},{"name":"School of Pharmacy, Anhui University of Chinese Medicine, Hefei 230012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahui","family":"He","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"},{"name":"School of Pharmacy, Anhui University of Chinese Medicine, Hefei 230012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minzhen","family":"Yin","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"},{"name":"Key Scientific Research Base of Traditional Chinese Medicine Heritage (Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences), National Cultural Heritage Administration, Beijing 100700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9494-4421","authenticated-orcid":false,"given":"Yujiao","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Anhui University of Chinese Medicine, Hefei 230012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7539-2377","authenticated-orcid":false,"given":"Huasheng","family":"Peng","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, Beijing 100700, China"},{"name":"School of Pharmacy, Anhui University of Chinese Medicine, Hefei 230012, China"},{"name":"Key Scientific Research Base of Traditional Chinese Medicine Heritage (Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences), National Cultural Heritage Administration, Beijing 100700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"145375","DOI":"10.1016\/j.foodchem.2025.145375","article-title":"Intelligent geographical origin traceability of Pu-erh tea based on multispectral feature fusion","volume":"492","author":"Chen","year":"2025","journal-title":"Food Chem."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"746","DOI":"10.1016\/j.crfs.2021.10.005","article-title":"Improved PCR-DGGE analysis by emulsion-PCR for the determination of food geographical origin: A case study on Greek PDO \u201cavgotaracho Mesolonghiou\u201d","volume":"4","author":"Dimitrakopoulou","year":"2021","journal-title":"Curr.
