Nowadays, there is a growing interest in natural, minimally processed, nutritional and healthy foods. Sprouted seeds can be offered as natural nutritive products. Regrettably, existing seed decontamination technologies are limited and have specific disadvantages. 5-aminolevulinic acid (5-ALA) as a novel and effective tool for wheat decontamination from microfungi is proposed in this work. Inhibition of wheat with 5-ALA revealed a drastically suppressed development of microfungi. Studies of wheat germination characteristics showed that 5-ALA stimulates the growth of wheat seedlings and roots without impairing the vigor of germination and the viability of seeds. 5-ALA also induces either marginal or significant activities of antioxidant enzymes which can be associated with enhanced cellular capacity to detoxify reactive oxygen species. The results indicate that 5-ALA application may be an effective, environmentally friendly and inexpensive technology to be used in producing sprouts for human consumption.
如今，人们对天然、最少加工、营养且健康的食品兴趣日益浓厚。发芽种子可作为天然营养产品提供。遗憾的是，现有的种子去污技术有限且存在特定缺点。本研究提出将5-氨基乙酰丙酸（5-ALA）作为从小麦中去除微真菌的一种新型有效工具。用5-ALA处理小麦后发现微真菌的生长受到显著抑制。对小麦发芽特性的研究表明，5-ALA能刺激小麦幼苗和根系生长，而不损害发芽活力和种子活力。5-ALA还能诱导抗氧化酶产生轻微或显著的活性，这可能与细胞解毒活性氧的能力增强有关。结果表明，应用5-ALA可能是一种有效、环保且廉价的技术，可用于生产供人类食用的豆芽。
