一般說明

丙酸 (PA) 是一种天然存在的羧酸,在其纯态下存在为无色、有难闻气味的腐蚀性液体。在水中可混溶。工业上它是由乙烯在羰基镍催化下发生氢羧化反应生成的。PA 具有减少食物摄入、降低血浆和肝脏中脂肪酸含量、改善组织胰岛素敏感性和发挥免疫抑制作用。丙酸是一种优良的原料,因为它稳定,廉价和安全,甚至可以作为食品添加剂使用。

應用

丙酸已被用作 罗伊氏乳杆菌 SK24.003 和 α- D -葡聚糖。

Undigested food is fermented in the colon by the microbiota and gives rise to various microbial metabolites. Short-chain fatty acids (SCFA), including acetic, propionic and butyric acid, are the principal metabolites produced. However, most of the literature focuses on butyrate

條款

In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
