竹木筷中过氧化氢在食品模拟物中迁移量的测定及其迁移规律的研究

Determination of Hydrogen Peroxide Migration Amount from Bamboo and Wooden Chopsticks to Food Simulants and Its Migration Law

  • 摘要: 目的:建立过氧化氢在不同食品模拟物中的测定方法,研究竹木筷中过氧化氢在不同食品模拟物中的迁移量及其迁移规律。方法:应用分光光度法测定过氧化氢,以不同食品模拟物(水基非酸性食品模拟物、水基酸性食品模拟物、酒精类食品模拟物、油基食品模拟物)中过氧化氢的质量对吸光度建立标准曲线,以相关系数、准确度和精密度为考察指标进行方法学验证;以食品模拟物的种类、迁移时间、迁移次数和迁移温度为考察因素,初步探索竹木筷中过氧化氢在食物模拟物中的迁移规律。结果:不同食品模拟物中过氧化氢建立的标准曲线相关系数均大于0.999,加标回收率范围84%~113%,加标平行样品间相对偏差(RSD)均小于10%。相同条件下,竹木筷中过氧化氢在油基模拟物中的迁移量最小;竹木筷中过氧化氢迁移存在一段快速迁移释放过程,而后转换为长时间缓慢迁移释放;过氧化氢的迁移为长时间反复迁移过程,试验至第8次仍有过氧化氢的迁移;随着温度的升高,过氧化氢迁移量会显著增加。结论:分光光度法测定竹木筷中过氧化氢在食品模拟物中迁移量准确可靠;市场部分竹木筷在不同食品模拟物中存在不同程度的过氧化氢迁移检出;其迁移规律为长时间,反复迁移的过程,增加温度可显著提高迁移速度;100 ℃煮沸处理可有效降低竹木筷中的过氧化氢的再迁移量。

     

    Abstract: Objective: Established a measurement method of hydrogen peroxide in different food simulants, studied the migration amount of hydrogen peroxide from bamboo and wooden chopsticks to different food simulants and its migration laws. Method: Used spectrophotometer to determine hydrogen peroxide, established a standard curve of hydrogen peroxide mass in different food simulants (water-based non-acid food simulators, water-based acid food simulators, alcohol food simulators, oil-based food simulators) and absorbance, used correlation coefficient, accuracy and precision as inspection indicators to verify the methodology, taking the type of the food simulants, time, frequency and temperature as investigating factors, the migration rule of hydrogen peroxide from bamboo and wooden chopsticks to the food simulants was initially explored. Result: The correlation coefficient of the obtained standard curve was greater than 0.999, the recovery rate of standard addition was 84%~113%, the maximum relative deviation (RSD) between spiked parallel samples were all lessed than 10%. The migration amount of hydrogen peroxide from bamboo and wood chopsticks to the oil-based simulant was smallest under the same conditions, the migration of hydrogen peroxide from bamboo and wooden chopsticks had a short rapid release process, and then converted to a long-term slow migration release, the migration was a long time repeated process, and there was still migration detected at the 8th time, as the temperature increased, the amount of migration increased significantly. Conclusion: Spectrophotometric determination of hydrogen peroxide amount in different food simulants was accurate and reliable, hydrogen peroxide migration were detected in different food simulants of some bamboo and wood chopsticks by this method, its migration law was a long time and repeated process, the migration rate could be significantly increased by increased the temperature, the remigration amount of hydrogen peroxide in bamboo and wood chopsticks could effectively lowered by boiled in water at 100 °C.
