UASSIGNED:由胶囊冲泡的咖啡含有可能危害生殖系统的雌激素化学物质(EC)。然而,没有研究调查饮用胶囊咖啡是否会导致这些ECs出现在尿液中。
未经评估:比较饮用胶囊咖啡与咖啡的效果对尿液中ECs外观的无塑料(法语按压)方法。
UNASSIGNED:参与者(n=30)被随机分为540毫升胶囊或法式咖啡,然后切换并在冲洗后消耗其他咖啡。在食用前收集尿液样本,在6小时和24小时。使用超高效液相色谱-串联质谱法分析咖啡和尿液样品的9种ECs:双酚A(BPA),双酚F(BPF),双酚S,邻苯二甲酸二(2-乙基己基)酯(DEHP),二苯甲酮,4-壬基酚(4-NP),邻苯二甲酸二丁酯,己内酰胺和对苯二甲酸二甲酯。
未经批准:在咖啡样品中,BPF(法语新闻:13.9ng/mL,胶囊:16.1ng/mL)和DEHP(胶囊:1.12ng/mL)。在6小时的尿液样本中,DEHP的检测频率在胶囊中为6.7%,在法国压榨咖啡中为13.3%。仅在食用后的一个尿液样品中检测到BPF。
UNASSIGNED:与食用法式压榨咖啡相比,食用胶囊咖啡不会增加尿液中的EC暴露。
UNASSIGNED: Coffee brewed from capsules contain estrogenic chemicals (ECs) that may harm the reproductive system. However, there are no studies investigating whether consuming capsule coffee causes these ECs to present in urine.
UNASSIGNED: Compare the effects of consuming capsule coffee vs. a plastic-free (French press) method on the appearance of ECs in urine.
UNASSIGNED: Participants (n = 30) were randomized to consume 540 mL of capsule or French press coffee once, then switched and consumed the other coffee after washout. Urine samples were collected prior to consumption, at 6 h and 24 h. Coffee and urine samples were analyzed for nine ECs using ultra-performance liquid chromatography with tandem mass spectrometry: bisphenol A (BPA), bisphenol F (BPF), bisphenol S, di(2-ethylhexyl) phthalate (DEHP), benzophenone, 4-nonylphenol (4-NP), dibutyl phthalate, caprolactam and dimethyl terephthalate.
UNASSIGNED: In coffee samples, BPF (French press: 13.9 ng/mL, capsule: 16.1 ng/mL) and DEHP (capsule: 1.12 ng/mL) were present. In 6 h urine samples, the detection frequency for DEHP was 6.7% in capsule and 13.3% in French press coffee. BPF was detected in only one urine sample post-consumption.
UNASSIGNED: Consuming capsule coffee did not increase urinary EC exposure compared to consuming French press coffee.
