【摘要】：本文以多酚含量及多酚得率為指標(biāo),比較了8種樹脂對茶葉提取液的吸附解吸效果,篩選出適合茶多酚分離純化的樹脂。在此基礎(chǔ)上,以單因素實驗的方法研究了水洗液用量、乙醇濃度及用量、供試液濃度和澄清度對產(chǎn)品中多酚含量以及多酚得率的影響。結(jié)果顯示,CG-8為純化茶多酚的最佳樹脂,當(dāng)茶多酚供試液濃度為10 mg/m L,水洗液(2BV)、70%乙醇(2.5BV)時,澄清度為70.90%左右時,得到的產(chǎn)品多酚含量為98%,得率為85.8%。該方法所得的產(chǎn)品多酚含量高,工藝綠色,符合生產(chǎn)要求。
[Abstract]:In this paper, the adsorption and desorption effects of 8 kinds of resins on tea extract were compared with polyphenol content and polyphenol yield as indexes, and the suitable resin for tea polyphenol separation and purification was selected. On the basis of this, the effects of the amount of water washing solution, the concentration and dosage of ethanol, the concentration and clarity of the sample solution on the content of polyphenol and the yield of polyphenol in the product were studied by single factor experiment. The results showed that CG-8 was the best resin for the purification of tea polyphenols. When the concentration of tea polyphenols was 10 mg/m / L, water washing solution (2BV) was 70% ethanol (2.5BV), the degree of clarity was about 70.90%, the polyphenol content of the product was 98% and the yield was 85.8%. The product obtained by this method has high polyphenol content, green process and meets the requirement of production.
