Consuming a plant-based diet is believed to offer protection against chronic diseases associated with oxidative stress. Plants in our diet exhibit diverse chemical compositions and antioxidant levels. The theory suggests that the antioxidants found in plants could play a role in the positive health outcomes associated with a plant-based diet, therefore there are thousand of drinks/beverages on teh market, advertised to be rich in antioxidants.
Beverages rich in antioxidants are considered beneficial for health due to the following reasons:
- Neutralizing Free Radicals: Antioxidants help neutralize free radicals in the body. Free radicals are unstable molecules that can cause oxidative stress, leading to damage to cells and DNA. Antioxidants counteract this process by donating electrons to stabilize free radicals, reducing their harmful effects.
- Reducing Oxidative Stress: Oxidative stress is associated with various chronic diseases, including cardiovascular diseases, cancer, and neurodegenerative disorders. Antioxidants help mitigate oxidative stress, potentially lowering the risk of these diseases.
- Anti-Inflammatory Properties: Some antioxidants also exhibit anti-inflammatory properties. Chronic inflammation is linked to numerous health issues, and reducing inflammation can contribute to overall well-being.
- Supporting Immune Function: Antioxidants, particularly vitamins C and E, play a role in supporting the immune system. A well-functioning immune system is crucial for defending the body against infections and illnesses.
- Protecting Cardiovascular Health: Antioxidants, such as flavonoids found in tea and red wine, have been associated with cardiovascular health benefits. They may help improve blood vessel function, reduce blood pressure, and have positive effects on cholesterol levels.
- Potential Cancer Prevention: Some studies suggest that a diet rich in antioxidants may contribute to the prevention of certain types of cancers. Antioxidants may help protect cells from damage that could lead to the development of cancer.
- Skin Health: Antioxidants play a role in maintaining skin health by protecting against oxidative damage caused by factors like UV radiation. They may contribute to a healthy complexion and help reduce signs of aging.
- Brain Health: Antioxidants, especially those with anti-inflammatory properties, are being investigated for their potential role in preserving cognitive function and reducing the risk of neurodegenerative diseases like Alzheimer’s.
The fastest way to measure TAC of a drink/beverage is the TAC sensors from ZP.
At ZP we are highly skilled in measuring TAC so please feel to contact ZP to discuss our TAC sensors, and the general landscape of TAC determination.
-
Total Antioxidant Capacity (TAC): This method measures the overall antioxidant capacity of a beverage by evaluating its ability to neutralize free radicals. It often involves the use of chemical assays such as the ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) or FRAP (Ferric Reducing Antioxidant Power) assays.
-
ORAC (Oxygen Radical Absorbance Capacity): This assay measures the antioxidant capacity of a beverage by assessing its ability to inhibit the action of free radicals. It is based on the oxidation of a fluorescent or chemiluminescent substance.
-
DPPH (2,2-diphenyl-1-picrylhydrazyl) Assay: This method involves the use of DPPH, a stable free radical, to evaluate the antioxidant capacity of a beverage. The reduction of DPPH by antioxidants is measured spectrophotometrically.
-
Folin-Ciocalteu Assay: This assay measures the total phenolic content in a beverage, as phenolic compounds often contribute to its antioxidant properties. It involves the reaction of phenolic compounds with Folin-Ciocalteu reagent, producing a blue color that can be quantified.
