The anti-oxidative capacity of milk tablet enriched with SOD (MKTES) and its effect on human electrical potential.

Superoxide dismutase (SOD) is a kind of main antioxidant enzyme produced in organism, which can eliminate superoxide anion produced by respiratory metabolism. Milk contains SOD, and SOD is added to dairy products as a food additive to improve the oxidation resistance of products. In order to study the antioxidant activity of milk tablet enriched with SOD (MKTES) and its function from the perspective of its effect on the electrical potential difference (EPD) of 12 acupuncture meridians, the oxidation-reduction potential (ORP), DPPH free radical scavenging capacity and SOD activity were studied respectively for the milk tablet (1.00 g milk powder) and MKTES (0.99 g milk powder + 0.01 g 2.53 × 10⁶ U/g SOD). 20 healthy volunteers were recruited and randomly divided into two groups for a double-blind clinical trial. The subjects in milk tablet group took sublingually 1 milk tablet, while the MKTES group took 1 tablet of MKTES....
