concentration was 15 mg / mL, the hemolysis rate of COS - O - KA1 -3 was less than 20% , while the
hemolysis activity of the same concentration of COS and KA was more than 30% . The DPPH free radical
scavenging rates of COS, KA, COS - O - KA1, COS - O - KA2 and COS - O - KA3 were 52郾 28% ,
59郾 33% , 85郾 21% , 87郾 35% and 82郾 83% , respectively. The scavenging activity of COS -O-KA1-3 on
+
ABTS free radical increased slowly and reached a stable level ( 83郾 87% , 85郾 76% , 82郾 33% ,
respectively) at 2郾 0 mg / mL, which was much higher than that of COS (39郾 65% ) and KA (46郾 54% ).
Meanwhile, owing to its non鄄cytotoxicity, COS -O-KA might be considered as a promising material for
antioxidant applications.

Civilized Baijiu Drinking and Healthy Life

LI Anjun
(Anhui Gujing Gongjiu Co Ltd / China Baijiu Health Research Institute, Bozhou 236826, China)

Abstract: As people蒺s health has become the center of national policies and guidelines, all trades are
focusing on improving people蒺s health, conducting in鄄depth scientific research, and accelerating the
transformation and upgrading of enterprises. Baijiu, as a popular drink, has also received extensive
attentions for its health functions. Many experimental results have shown that Baijiu contains a lot of
health factors that are beneficial to the human body. Meanwhile, civilized drinking is beneficial to human
health and can reduce the risk of a variety of diseases. Baijiu鄄related researchers and Baijiu
manufacturing companies should continue to conduct further researches on health benefits of Baijiu, and
correctly guide consumers to understand the health attributes of Baijiu. We should take people蒺s health as
the core and scientific research as the driving force to improve Baijiu products and tell a good story of
Baijiu.
Keywords: Baijiu; health; health factor; civilized drinking; sensible drinking
