Background
Aging is the biggest killer of human organs, and free radicals (free radials) generated by the body are the most important cause of organ aging. When the body's mechanisms regulating free radicals are lost or unbalanced, excessive free radical production can damage cellular DNA, alter intracellular protein structures, attack cell membranes, and ultimately lead to somatic cell death. Skin aging is also caused by a rapid increase in the amount of active oxygen induced by long-term exposure to ultraviolet (UV exposure) or heat (heat exposure), resulting in diseases such as skin darkness and skin cancer.
Hypertension, hyperlipemia and hyperglycemia are collectively called as "three highs", and is a cardiovascular and cerebrovascular disease which is harmful to human health. According to the speculation of experts, the number of hypertension patients worldwide will exceed 15 hundred million in 2025. Effective treatment or prevention of hypertensive disorders has become a worldwide health problem.

(1) Total antioxidant (T-AOC) Capacity determination
In the invention, the antioxidation capacity of the bifidobacterium lactis is evaluated mainly by measuring the inhibition rate of Angiotensin Converting Enzyme (ACE), the total antioxidation (T-AOC) capacity and the superoxide anion free radical scavenging capacity.
The Angiotensin Converting Enzyme (ACE) determination method mainly comprises a colorimetric method, an enzyme coupling method and the like. In the present invention, the Angiotensin Converting Enzyme (ACE) inhibitory activity is measured by ultraviolet spectrophotometry: taking a 2mL centrifuge tube, adding 50 mu L of 50mmol/L sodium borate buffer solution with 5mmol/L Hippuryl-His-Leu (HHL) as a substrate, adding 20 mu L of liquid to be detected, mixing, preheating for 3min in a water bath at 37 ℃, adding 10 mu L ACE enzyme solution, reacting for 30min at 37 ℃, and adding 100 mu L1 mol/L hydrochloric acid to stop the reaction. 1.7mL of ethyl acetate was added, followed by shaking for 15s, centrifugation at 3000 Xg for 10min, and separation of the upper 1mL of ethyl acetate layer (layer on which the sample was present). Heating to volatilize and remove the organic solvent, adding 1mL of deionized water, shaking to completely dissolve hippuric acid, and measuring the light absorption value of the sample at 228nm by using a micro ultraviolet spectrophotometry. The ACE inhibition ratio (ACEI) is calculated as follows:
Figure BDA0002800797380000061
wherein A represents the absorbance of ACE with HHL to completely produce hippuric acid (control); b represents the light absorption value (sample) of hippuric acid generated after the liquid to be detected reacts with ACE and HHL; c represents the light absorption value of hippuric acid generated after the reaction of adding ACE hydrochloride and HHL.
The total antioxidant capacity (T-AOC) is measured by adopting a total antioxidant capacity (T-AOC) detection kit purchased from Nanjing, and the operation is carried out according to the kit instruction. The antioxidant can reduce ferric ions into ferrous ions which can form a stable complex with phenanthroline substances, and the oxidation resistance can be measured by a colorimetric method. In the determination process, when a sample to be detected is mixed with a reagent provided by the kit, the mixture is fully mixed by a vortex mixer, placed in water bath at 37 ℃ for 30 minutes for 10 minutes, the wavelength is 520nm, the optical path is 1cm, double distilled water is adjusted to zero, and the absorbance value of each tube is determined.
Figure BDA0002800797380000062
The superoxide anion free radical scavenging ability is measured by a pyrogallol-spectrophotometer method. The pyrogallol-spectrophotometry is widely applied to the primary screening of antioxidants in the food and medicine industries and the evaluation of the antioxidant function of various active substances for eliminating superoxide anion free radicals. The pyrogallol autoxidation process is a chain reaction and can generate superoxide anion free radicals, the content of the oxidation products of the pyrogallol autoxidation process can be detected by a spectrophotometer, and the oxidation resistance of the antioxidant substances can be indirectly evaluated by the method. The method comprises the following specific steps: 0.88mL of 0.1mol/L Tris-HCl buffer (pH 8.2) was put in a test tube, and 0.2mL of 1.0mmol/L ethylenediaminetetraacetic acid (EDTA), 0.2mL of the sample, and 0.3mL of distilled water were added in this order. Reacting in 25 ℃ water bath for 10min, adding 0.4mL 9.0mmol/L pyrogallol, reacting for 60min, and adding 100 uL 12.0mol/L HCl to terminate the reaction. All above were averaged 3 times and the experiment was repeated 3 times. Calculating the formula: clearance = (Ac-As)/Ac × 100%, where As: measuring the absorbance at a wavelength of 325 nm; ac: the blank tube was used with 0.2mL of distilled water instead of the sample, and the absorbance was measured by the same tube as the operation method.

(2) Detection of other antioxidant-related abilities in BL-99 fermentation samples
In the invention, other oxidation resistance related capacities in BL-99 fermentation samples are also detected, including total superoxide dismutase (T-SOD) activity, gamma-aminobutyric acid (GABA) content and B vitamin content of the supernatant at different fermentation times.
In the invention, the activity of the total superoxide dismutase (T-SOD) is determined by adopting a total superoxide dismutase (T-SOD) kit which is purchased from Nanjing and operated according to the kit instruction. The reaction system of xanthine and xanthine oxidase produces superoxide anion radical which oxidizes hydroxylamine to form nitrite, which is purple red under the action of color developing agent, and the absorbance of the product is measured with visible spectrophotometer. When the tested sample contains SOD, it has specific inhibition action on superoxide anion free radical, so that the formed nitrite is reduced, and the absorbance value of the measuring tube is lower than that of the control tube in the colorimetric process, and the activity of SOD in the sample can be obtained by means of calculation.

In the invention, the method for measuring the content of gamma-aminobutyric acid (GABA) is carried out according to QB/T4587-2013 gamma-aminobutyric acid.
In the invention, the content of B vitamins is determined by a high performance liquid chromatograph, and the specific operation conditions refer to HPLC detection of water-soluble vitamins (Liyan, food research and development, 2018) in black skin termitomyces albuminosus.
In the present invention, the results of measuring total superoxide dismutase (T-SOD) activity, gamma-aminobutyric acid (GABA) content and B vitamins of BL-99 probiotic fermentation supernatants at different fermentation times are shown in Table 4.
