【摘要】 目的:研究羊骨提取的骨盐乳剂对米心红茶原料的固定理氟作用。方法:将乳剂掺入米心红茶原料,晾干,分析水溶性氟、茶色及茶多酚。结果:当红茶原料中加入0%~2.5%再生骨盐乳剂(干骨盐计),可使茶原料中0%~63.31%水溶性氟被固定,固定剂用量为1.5%时水溶性氟被控制到300 mg/kg以下,茶水色和茶多酚含量无明显改变。结论:红茶原料的水溶性氟可被骨盐乳剂所固定。更多还原

【Abstract】 Objective: To Study the effect of fixing-fluoride of bone salt emulsion extracted from sheep bone for raw material of Mixin black tea. Methods: Adding the emulsion into raw material of Mixin black tea,dried it in the air and analysed the content of soluble fluoride﹑tea color and polyphenol in the material treated.Results: It was found that a range of 0%～63.31% of soluble fluoride in the raw tea was fixed as adding a dosage of 0%～2.5% of the emulsion calculated as dry bone salt,no changes were found in tea color and polyphenol.The soluble fluoride content was controlled to the level under 300mg /kg as adding a dose of 1.5% of emulsion reagent.Conclusion: The soluble fluoride of raw black tea can be fixed by bone salt emulsion.更多还原
