Abstract：
Tucupi is a broth derived from cassava roots which is produced after the spontaneous fermentation of manipueira (the liquid portion obtained by pressing cassava roots), followed by cooking. This product is widely consumed along with traditional dishes in the Brazilian Amazonia and is already used in different places worldwide. In this study, tucupi obtained from the markets of Belém (Pará, Brazil) and produced using agroindustrial (11 samples) and non-agroindustrial (11 samples) units were investigated to determine their physicochemical characteristics, total and free HCN contents, and free bioactive amine profiles. Most of the samples showed significant variations (p ≤ 0.05) in pH (2.82-4.67), total acidity (0.14-1.36 g lactic acid/100 mL), reducing sugars (up to 2.33 g/100 mL), and total sugars (up to 4.35 g/100 mL). Regarding the amines, four biogenic amines (0.5-4.2 mg/L tyramine, 1.0-23.1 mg/L putrescine, 0.5-66.8 mg/L histamine, and 0.6-2.9 mg/L tryptamine) and one polyamine (0.4-1.7 mg/L spermidine) were identified in the tucupi samples. Even in the tucupi produced using the agroindustrial units, which had quality seals provided by the local regulatory agency, high levels of biogenic amines (4.4-78.2 mg/L) were observed, as well as high dosages of total (8.87-114.66 mg/L) and free (0.80-38.38 mg/L) HCN. These facts highlight the need for better knowledge regarding the product manufacturing process to establish standardization and high-quality conditions for tucupi processing since high contents of biogenic amines and HCN are commonly associated with adverse health effects.
摘要：
Tucupi是木薯根的肉汤，是在manipueira（通过压制木薯根获得的液体部分）自发发酵后产生的，接着做饭。该产品与巴西亚马逊地区的传统菜肴一起被广泛消费，并已在全球不同地方使用。在这项研究中,图库皮从贝伦市场获得(帕拉，巴西）并使用农用工业（11个样品）和非农用工业（11个样品）单位生产，以确定其理化特性，总HCN含量和游离HCN含量，和游离的生物活性胺谱。大多数样品在pH值（2.82-4.67）方面表现出显着变化（p≤0.05），总酸度（0.14-1.36克乳酸/100毫升），还原糖（高达2.33克/100毫升），和总糖（高达4.35g/100mL）。关于胺，四种生物胺（0.5-4.2mg/L酪胺，1.0-23.1mg/L腐胺，0.5-66.8毫克/升组胺，在tucupi样品中鉴定出0.6-2.9mg/L的色胺）和一种多胺（0.4-1.7mg/L的亚精胺）。即使在使用农业工业单位生产的图库比，有当地监管机构提供的质量印章，观察到高水平的生物胺（4.4-78.2mg/L），以及高剂量的总（8.87-114.66mg/L）和游离（0.80-38.38mg/L）HCN。这些事实突出表明，需要更好地了解产品制造过程，以建立tucupi加工的标准化和高质量条件，因为高含量的生物胺和HCN通常与不利的健康影响有关。
