概括

这项研究在即溶咖啡和咖啡替代品中发现了类似的烯胺和HMF水平. 然而,更高的速溶咖啡消费导致更大的饮食暴露在这些化合物中,具有不同的生物可访问性.

科学领域:

食品化学和毒理学食品化学和毒理学
饮食暴露评估的评估
生物可访问性研究生物可访问性研究

背景情况:

烯胺和甲 (HMF) 是在各种食品中发现的工艺污染物,包括咖啡.
速溶咖啡 (IC) 和咖啡替代品 (CS) 广泛消费,需要了解它们的污染物概况和潜在的健康影响.
评估这些化合物的生物可访问性对于现实的饮食风险评估至关重要.

研究的目的:

评估在商业IC和CS中烯胺和HMF的发生和生物可访问性.
为了比较IC和CS的暴露水平,考虑典型的消费模式.
调查添加牛奶对这些化合物的生物可访问性的影响.

主要方法:

在商业IC和CS样本中分析烯胺和HMF含量.
标准化体外胃肠道消化方案 (INFOGEST) 的应用.
在模拟的消化条件下的化合物生物可访问性的评估,有或没有牛奶.

主要成果:

烯胺和HMF水平在IC和CS之间是可比的,水平低于欧盟基准.
由于消费率较高,西班牙人口对烯胺和HMF的暴露明显高于IC.
胃肠道消化减少了烯胺的生物可访问性,而HMF的生物可访问性在IC下降,但在CS增加;牛奶没有显著的影响.

结论:

与咖啡替代品相比,速溶咖啡是通过饮食暴露于烯胺和HMF的更大来源.
生物可访问性在IC和CS之间有很大的差异,这凸显了体外消化研究的必要性.
在现实的消费场景中评估食品的生物可访问性对于准确的饮食风险评估至关重要.

Physical Properties of Amines

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Mutagenicity and Carcinogenicity

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
