【摘要】：建立了食品添加劑部分氫化木松香季戊四醇酯定性表征和定量分析方法。采用紅外光譜法、環(huán)球法對(duì)部分氫化木松香季戊四醇酯進(jìn)行定性分析,采用化學(xué)滴定法對(duì)其酸值進(jìn)行定量分析,結(jié)果表明食品添加劑部分氫化木松香季戊四醇酯紅外光譜與FCC標(biāo)準(zhǔn)譜圖一致,軟化點(diǎn)及酸值也符合FCC要求。
[Abstract]:A method for qualitative characterization and quantitative analysis of pentaerythritol ester of partially hydrogenated rosin was established. The pentaerythritol ester of some hydrogenated rosin was qualitatively analyzed by infrared spectroscopy and universal method. The acid value of pentaerythritol ester was quantitatively analyzed by chemical titration. The results showed that the infrared spectra of some hydrogenated rosin pentaerythritol esters were consistent with the FCC standard spectrum, and the softening point and acid value also met the requirements of FCC.
