However, little is known about the effects of sulfur and phosphorus application on potato tuber flavor. This study experimentally compared the effects of the individual and combined application of phosphorus and sulfur fertilizers on the flavor of potato tubers. The research examined the sensory characteristics of flavor under various fertilization methods, investigated changes in the types and contents of volatile flavor compounds, and conducted analyses on flavor precursor compounds. The experimental results showed that the application of phosphorus and sulfur fertilizers, either individually or in combination significantly increased the content of linoleic acid and linolenic acid. After the combined application of phosphorus and sulfur fertilizers, the starch and the reducing sugar content also significantly increased. (E,E)-2,4-Nonadienal and Decanal are closely correlated with fatty acid content. Dimethyl sulfide and Trimethyl sulfide contents are significantly related to methionine content. This also significantly enhances the fatty taste characteristics of the tubers but weakens the potato flavor characteristics. Hence, the application of phosphorus and sulfur can affect the accumulation of primary metabolic products in tubers, thereby affecting flavor quality. Compared with the individual application of phosphorus or sulfur fertilizers, when phosphorus fertilizer is applied at 180 kg\u00b7ha\u22121 and sulfur fertilizer at 90 kg\u00b7ha\u22121 in combination, it can further enrich the roasted flavor characteristics of potatoes and maximize the enhancement of potato flavor quality. This provides valuable theoretical support for achieving high-quality agricultural development.<\/jats:p>","DOI":"10.3390\/foods12203764","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T06:07:26Z","timestamp":1697177246000},"page":"3764","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Impact of the Individual and Combined Application of Phosphorus and Sulfur Fertilizers on Potato Tuber Flavor"],"prefix":"10.3390","volume":"12","author":[{"given":"Kaifeng","family":"Li","sequence":"first","affiliation":[{"name":"College of Agronomy and Biotechnology, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Yunnan Engineering Research Center of Tuber and Root Crop Bio-Breeding and Healthy Seed Propagation, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Tuber and Root Crop Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maoxing","family":"Li","sequence":"additional","affiliation":[{"name":"College of Agronomy and Biotechnology, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Yunnan Engineering Research Center of Tuber and Root Crop Bio-Breeding and Healthy Seed Propagation, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Tuber and Root Crop Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinhua","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Agronomy and Biotechnology, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Yunnan Engineering Research Center of Tuber and Root Crop Bio-Breeding and Healthy Seed Propagation, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Tuber and Root Crop Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huachun","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Agronomy and Biotechnology, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Yunnan Engineering Research Center of Tuber and Root Crop Bio-Breeding and Healthy Seed Propagation, Yunnan Agricultural University, Kunming 650201, China"},{"name":"Tuber and Root Crop Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"ref_1","unstructured":"FAO (2023, October 02).
