摘要:
为了研究不同干燥方式对黄秋葵花茶品质及体外抗氧化能力的影响,采用50 ℃热风干燥、70 ℃热风干燥、微波干燥及真空冷冻干燥处理黄秋葵花,分析了黄秋葵花茶的外观品质、色泽及花茶和茶水中多糖含量、黄酮含量以及抗氧化能力和感官品质。结果表明,50 ℃热风干燥和70 ℃热风干燥处理的黄秋葵花茶和茶水外观品质、抗氧化能力差异不显著(P>0.05),多糖和黄酮含量略有差异;微波干燥处理的黄秋葵花茶外观收缩严重,内部和外部有焦糊点,但香气浓郁,并具有较高的抗氧化能力;真空冷冻干燥处理的黄秋葵花茶外观形态匀称、色泽鲜亮,花茶和花茶水中多糖和黄酮含量最高,抗氧化能力最高,花茶水色泽金黄通透、风味纯正,但香气较平淡。本试验结果为黄秋葵花茶综合利用和加工品质控制提供了技术指导。
Abstract:
In order to investigate the effects of different drying methods on quality and antioxidant capacity, the okra flowers were dried by 50 ℃ hot-air drying, 70 ℃ hot-air drying, microwave drying and vacuum freeze drying. The appearance quality, color, polysaccharide content, flavonoids content, antioxidant capacity and sensory quality of flower and tea were analyzed. The results showed that there was no significant difference in appearance quality and antioxidant capacity of okra flower and tea dried with 50 ℃ hot-air drying and 70 ℃ hot-air drying (P>0.05), but there was a slight difference in the polysaccharide and flavonoids content. Serious appearance shrinkage happened in microwave-dried okra flower, which had the paste point, a strong flavor and higher antioxidant capacity. The freeze-dried okra flower had symmetrical shape and bright color, also had the highest polysaccharide and flavonoids content, the highest antioxidant capacity. The tea of freeze-dried okra flower had golden color and pure flavor, but the fragrance was weaker. The results of this experiment can provide technical guidance for comprehensive utilization and quality control of okra flowers.
