Abstract

BACKGROUND

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.

RESULTS

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).

CONCLUSIONS

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 (CO₂) 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).

农艺措施对马铃薯生长、营养状况和油炸适宜性的影响。

背景：本研究研究了硫营养、具有碳捕获功能的玄武岩骨料（BA）的应用以及发光二极管（LED）光下的快速育种对马铃薯营养状况和脆薯生产中丙烯酰胺形成的影响。结果：添加硫的金牛座土豆显示葡萄糖、蔗糖和总氨基酸减少，而天冬酰胺增加。添加硫和BA后，金牛座和克莱尔女士薯片中丙烯酰胺含量无显著差异。与对照（80 ~ 90 cm）相比，LED光快速育种使所有品种株高（50 ~ 60 cm）降低。在LED光下生长的块茎显示出更高的葡萄糖和果糖水平，并且增加了薯片中丙烯酰胺的形成（Lady Claire 78.90%, Taurus 592.58%, Desiree 70.25%）。结论：硫肥可以降低马铃薯块茎中的糖含量，对某些马铃薯品种有益。基岩骨料可以作为一种从大气中吸收二氧化碳的创新工具安全地应用于马铃薯生长过程中，对块茎的营养状况没有负面影响，对薯片中丙烯酰胺的形成也没有影响。事实证明，LED光照条件不适合马铃薯生长，尤其是用于油炸行业的马铃薯，这会增加糖和丙烯酰胺的含量。©2025作者。约翰威利父子有限公司代表化学工业协会出版的《食品与农业科学杂志》。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
