This study investigated the effect of sulfur nutrition, basalt rock aggregate (BA) application, with a carbon capture function, and speed breeding under light-emitting diode (LED) light, on the nutritional profile of potatoes and acrylamide formation in crisp production.
Taurus potatoes grown with sulfur showed reduced glucose, sucrose, and total amino acids, and increased asparagine. No difference in acrylamide content was observed in crisps from Taurus and Lady Claire cultivars, with either sulfur or BA application. Speed breeding under LED light reduced plant height in all cultivars (50-60 cm) in comparison with controls (80-90 cm). Tubers grown under LED light exhibited higher levels of glucose and fructose, and increased formation of acrylamide in crisps (78.90% for Lady Claire, 592.58% for Taurus, and 70.25% for Desiree).
Sulfur fertilization could benefit certain potato cultivars by lowering sugar levels in the tubers. Basal rock aggregate can be applied safely during the growth of potatoes as an innovative tool for sequestering carbon dioxide (CO) from the atmosphere, with no negative effect on tubers' nutritional profile and no influence on acrylamide formation in crisps. The LED light conditions proved to be unsuitable for potato growth, especially if the potatoes were destined for the frying industry, increasing both sugars and acrylamide content. © 2025 The Author(s).

本研究调查了硫营养、具有碳捕获功能的玄武岩集料（BA）施用以及在发光二极管（LED）光照下的快速育种对马铃薯营养成分和薯片生产中丙烯酰胺形成的影响。
施用硫种植的金牛座马铃薯葡萄糖、蔗糖和总氨基酸含量降低，天冬酰胺含量增加。施用硫或BA后，金牛座和克莱尔夫人品种的薯片丙烯酰胺含量没有差异。与对照（80 - 90厘米）相比，LED光照下的快速育种降低了所有品种的株高（50 - 60厘米）。LED光照下生长的块茎葡萄糖和果糖含量较高，薯片丙烯酰胺形成增加（克莱尔夫人品种为78.90%，金牛座品种为592.58%，德西蕾品种为70.25%）。
施硫可通过降低块茎中的糖分水平使某些马铃薯品种受益。玄武岩集料可在马铃薯生长期间安全施用，作为从大气中封存二氧化碳（CO）的创新工具，对块茎营养成分无负面影响，对薯片丙烯酰胺形成无影响。事实证明，LED光照条件不适用于马铃薯生长，特别是如果马铃薯用于油炸行业，会增加糖分和丙烯酰胺含量。© 2025作者。由John Wiley & Sons Ltd代表化学工业协会出版的《食品与农业科学杂志》
