The typical Korean diet contains a significant quantity of owing to its unique taste and health benefits. However, the presence of anti-nutritional and toxic substances, such as biogenic amines and microbial pathogens, in has resulted in a loss of revenue and poor consumer health. The present study focused on the identification and quantification of different biogenic amines, pathogenic , and yeast counts in 36 products (designated as De-1 to De-36, 500 g each) procured from the different cottage industries situated in different parts of the Republic of Korea. The results indicated, only three samples were contaminated with , exceeding the recommended limit (4 log CFU/g) suggested by the national standards of Korea. A total of six distinct yeasts were identified in different samples, whose comprehensive enzymatic profiling suggested the absence of harmful enzymes such as N-acetyl-β-glucosaminidase, α-chymotrypsin, and β-glucuronidase. The biogenic amines were detected in the range of 67.68 mg/kg to 2556.68 mg/kg and classified into six major groups based on hierarchical cluster analysis. All samples contained tryptamine, putrescine, cadaverine, histamine, and tyramine, while 94.44% were positive for spermidine and spermine. The results documented the analysis of traditional cottage industry and suggest the need for constant monitoring to ensure the safety of food for the consumer.
典型的韩国饮食因其独特的口味和健康益处而含有大量[某种食物，原文未明确]。然而，[该食物]中存在抗营养和有毒物质，如生物胺和微生物病原体，导致了收入损失和消费者健康不佳。本研究重点对从大韩民国不同地区的不同家庭手工业采购的36种[该食物]产品（命名为De - 1至De - 36，每种500克）中的不同生物胺、致病[微生物，原文未明确]和酵母数量进行鉴定和定量。结果表明，只有三个样品被[该致病微生物]污染，超过了韩国国家标准建议的推荐限量（4 log CFU/g）。在不同的[该食物]样品中总共鉴定出六种不同的酵母，其综合酶谱分析表明不存在诸如N - 乙酰 - β - 葡萄糖苷酶、α - 胰凝乳蛋白酶和β - 葡萄糖醛酸酶等有害酶。生物胺的检测范围为67.68 mg/kg至2556.68 mg/kg，并根据层次聚类分析分为六大类。所有[该食物]样品都含有色胺、腐胺、尸胺、组胺和酪胺，而94.44%的样品亚精胺和精胺呈阳性。结果记录了对传统家庭手工业[该食物]的分析，并表明需要持续监测以确保消费者的食品安全。
