Quinoa and amaranth are of special interest since they are increasingly used for the development of new bakery products with enhanced nutritional value. The aim of the study was to evaluate the agronomic, microbiological, and nutritional characteristics of quinoa and amaranth seeds grown in Southern Italy. For this reason, quinoa Titicaca and three amaranth accessions (5, 12, and 14) were cultivated in different experimental fields in the Campania Region and analyzed for the cultivation aspects, chemical composition, and microbiological quality of the seeds. All seeds showed a good adaptability to cultivation in the experimental areas of the Mediterranean basin. Quinoa seeds were characterized by their higher protein, fat, and ash content than the amaranth seeds, which were characterized by their higher value in dietary fiber. All seeds, regardless of the geographical area of production, were contaminated with yeasts, moulds, and spore-forming bacteria, mainly , , and , as identified by 16S rRNA sequencing analysis. So, the detection of spp. must be strongly monitored, as quinoa and amaranth seeds could be used in bread production, where they can cause ropiness, resulting in great economic losses for the industries.
藜麦和苋属植物特别受关注，因为它们越来越多地被用于开发具有更高营养价值的新型烘焙产品。本研究的目的是评估在意大利南部种植的藜麦和苋属植物种子的农艺学、微生物学和营养特性。因此，藜麦蒂卡卡品种和三个苋属植物种质（5号、12号和14号）在坎帕尼亚大区的不同试验田进行种植，并对种子的种植方面、化学成分和微生物质量进行分析。所有种子在地中海盆地试验区均表现出良好的种植适应性。藜麦种子的特点是蛋白质、脂肪和灰分含量高于苋属植物种子，而苋属植物种子的特点是膳食纤维含量较高。通过16S rRNA测序分析确定，所有种子，无论生产的地理区域如何，均被酵母、霉菌和产芽孢细菌污染，主要是 、 、 和 。因此，必须严格监测 菌的检测，因为藜麦和苋属植物种子可用于面包生产，在面包生产中它们会导致面包发黏，给行业造成巨大经济损失。
