The antioxidant properties of arracacha not only contribute to its potential health benefits but also help maintain the quality and shelf life of minimally processed arracacha products.
What research Says?
- Arracacha fights oxidative stress with special enzymes. Researchers looked at how cold storage affects these enzymes in arracacha roots. They kept the roots at 5°C and 10°C for 28 days. They then measured two enzymes, polyphenoloxidase and peroxidase, and checked the levels of phenolic compounds. The study showed that both temperatures made the roots darken inside and out, especially at 5°C. During the cold storage, the enzyme activities and phenolic compound levels went up. These enzymes are key in responding to stress and causing the darkening. This shows they help reduce oxidative stress.
- A study looked at how rosemary extract (Rosmarinus officinalis L.) helps keep arracacha cubes fresh when vacuum-packed. They tried different amounts of the extract and various times. They found that a mix with 7% rosemary extract for 20 minutes worked best. It kept the arracacha good for 5 days in the fridge at 5°C. This mix lowered oxidation, just like chemical antioxidants such as ascorbic acid and citric acid. It means the compounds in rosemary can help reduce spoilage in arracacha.
2. Have anti-cancer effects
Extracts from arracacha can induce apoptosis, a process of programmed cell death crucial for eliminating cancer cells. Specifically, research on HeLa cells, a type of cervical cancer cell, demonstrated that arracacha extracts increased the expression of caspases 3/7 and Bax, proteins that promote apoptosis, while decreasing the levels of β-actin, nitric oxide (NO•), and hypoxia-inducible factor-1 (HIF-1), which are associated with cancer progression.
What Research Says?
- Arracacha has many health-boosting substances, like antioxidants and sesquiterpenoids. A key one is xanthorrhizol. It’s a sesquiterpenoid also in Curcuma xanthorrhiza and has shown strong activity against the spread of diseases in experiments.
- The antioxidant effects of Arracacha have been looked at, especially when mixed with other natural extracts. For example, researchers tested how well rosemary extract protects Arracacha. They found that a 7% mix of rosemary extract gave good antioxidant protection while being stored. This means that the antioxidants in Arracacha, made even stronger by other natural extracts, might help fight cancer by lowering oxidative stress, which can lead to cancer.
