- Dietary Fiber
- Organic Acids: Ripe papaya contains several organic acids, including citric acid, malic acid, and succinic acid.
- Citric acid: a common organic acid found in many fruits and widely known for its role in the citric acid cycle and its potential antioxidant properties.
- Malic acid: another prevalent organic acid, malic acid is a key component in the respiration process and contributes to the fruit’s flavor.
- Succinic acid: this acid plays a role in the Krebs cycle and is also present in papaya extracts.
- Tartaric acid: Identified in papaya fruit, tartaric acid is another non-volatile organic acid that adds to the fruit’s chemical profile.
- Fumaric acid: Found in papaya, fumaric acid is a dicarboxylic acid involved in cellular respiration and the urea cycle.
- Malonic acid: Also present in papaya, malonic acid is a dicarboxylic acid that acts as a competitive inhibitor of succinate dehydrogenase.
- Quinic acid: Detected in ripe papaya, quinic acid is a non-volatile organic acid with various reported bioactivities, according to MDPI.
- Carotenoids: The fruit is a source of carotenoids like β-carotene and cryptoxanthin.
- Lycopene:A prominent carotenoid, especially in the pulp, and a strong antioxidant.
- Zeaxanthin
- β-Carotene: A carotenoid with provitamin A activity, essential for vision and immune function.
- β-Cryptoxanthin: Another provitamin A-active carotenoid found in papaya, also important for health.
- Lutein: Found in higher concentrations in the peel, often in esterified forms.
-
- Health and Nutritional Significance
- Provitamin A: β-Carotene and β-cryptoxanthin are precursors to Vitamin A, which is crucial for a healthy immune system, proper growth, and development.
- Antioxidant Properties: Carotenoids, including lycopene, are powerful antioxidants that help protect the body from oxidative stress.
- Dietary Source: Papaya serves as an excellent dietary source of these beneficial compounds, particularly for populations in developing countries where Vitamin A deficiency is common.
- Factors Influencing Carotenoid Content
- Variety: Different papaya varieties can have varying carotenoid profiles.
- Ripeness: The stages of ripeness can influence the types and amounts of carotenoids.
- Part of the Fruit: The concentration and types of carotenoids can differ between the pulp and the peel.
- Health and Nutritional Significance
- Antioxidant: Due to its high content of phenolic compounds and vitamins, papaya extract is a potent antioxidant, helping to protect cells from damage.
- Digestive Aid: The enzyme papain breaks down proteins, making the fruit beneficial for digestion.
- Anti-inflammatory: Papaya extracts possess anti-inflammatory properties and can help reduce inflammation by lowering reactive oxygen species (ROS).
Benefits
- Exfoliation: The extract contains enzymes like papain, which have a keratolytic action, breaking down dead cells on the skin’s surface to promote a smoother, brighter, and softer complexion, improving skin texture and brightness.
- Depilation: The proteolytic enzymes can help weaken hair follicles, making it useful in depilatory products.
- Skin Renewal: It supports cell regeneration and is ideal for use in night creams or cleansers for skin that looks renewed and fresh.
- Anti-Aging & Firming: The antioxidant properties help to firm, smooth and improve the elasticity of mature skin. Its antioxidants and ability to improve skin elasticity make it a good ingredient for anti-aging care. By stimulating collagen production and reducing the effects of aging, it can minimize the appearance of wrinkles and fine lines.
- Moisturization: Ingredients like glycerin and beneficial compounds from the fruit provide deep moisture and help the skin retain water. It is hydrating and nourishing, improving skin texture and promoting soft, supple skin..
- Brightening, Radiance & Smoothing: Regular use can reduce the appearance of dullness, flaky patches, and even reduce the visibility of sun spots or discoloration, Papaya extract can leave the skin looking fresher, brighter, and more radiant.
