TITLE:
摘要: 目的:优化生姜皮的干燥工艺,建立生姜皮的质量标准。方法:以含水量7%~13%为干燥程度控制标准,在50、60、70、80、90 ℃温度下分别对生姜皮干燥不同时间(0.5~10.0 h)后取样测定含水量,筛选各温度下的最优干燥时间;再测定各温度下最优干燥时间所得样品中6-姜辣素、8-姜酚、6-姜烯酚、10-姜酚的含量,以此4种姜酚成分含量为指标优化生姜皮的干燥温度及干燥时间并进行验证试验;以最优工艺对10个不同产地的生姜皮进行干燥后测定其含水量、总灰分、水溶性浸出物、挥发油、6-姜辣素、8-姜酚、10-姜酚,据此建立质量标准。结果:生姜皮在50、60、70、80、90 ℃温度下的干燥时间分别确定为10.0、4.2、2.6、1.5、1.1 h;其中,最优干燥工艺为50 ℃干燥10.0 h;验证试验中,6-姜辣素、8-姜酚、6-姜烯酚、10-姜酚含量的RSD分别为1.46%、1.09%、1.35%、1.12%(n=3)。生姜皮的质量标准建议定为总灰分不得过18.0%,水溶性浸出物、挥发油、6-姜辣素、8-姜酚、10-姜酚分别不得少于18.0%、1.30%、0.730%、0.060%、0.100%。结论:优化的生姜皮干燥工艺合理可靠、稳定性好、方法简便,为规范生姜皮饮片的干燥工艺和质量标准提供了科学依据;建立的生姜皮质量标准可行。
ABSTRACT: OBJECTIVE: To optimize the drying technology of Zingiber officinale peel and establish its quality standard. METHODS: Moisture content was determined in samples after being dried for different time (0.5-10.0 h) under 50, 60, 70, 80, 90 ℃. Optimal drying time under each temperature was screened by using moisture content of 7%-13% as dryness for controlling standard. Then contents of 6-gingerol, 8-gingerol, 6-shogaol, 10-gingerol in samples dried for optimal drying time under different temperatures were measured, using the 4 gingerol contents as indexes to optimize the drying temperature and time. And verification test was conducted. The moisture, total ash, water soluble extract, volatile oil, 6-gingerol, 8-gingerol and 10-gingerol of Z. officinale peel from 10 different producing areas were detected to establish quality standard after being dried with the optimal technology. RESULTS: The drying time of Z. officinale peel under 50, 60, 70, 80, 90 ℃ was determined as 10.0, 4.2, 2.6, 1.5, 1.1 h, respectively. The optimal drying technology was 50 ℃ drying for 10.0 h. Verification test showed RSDs of 6-gingerol, 8-gingerol, 6-shogaol, 10-gingerol contents were 1.46%, 1.09%, 1.35%, 1.12% (n=3), respectively. The quality standard of Z. officinale peel was suggested that total ash was no more than 18.0%; water soluble extract, volatile oil, 6-gingerol, 8-gingerol, 10-gingerol were respectively no less than 18.0%, 1.30%, 0.730%, 0.060%, 0.100%. CONCLUSIONS: The optimized drying technology of Z. officinale peel is reasonable, reliable, stable and simple, which provides a scientific basis for standardizing the drying technology and quality standard of Z. officinale peel. The established quality standard is feasible.
