Product Popularization

Rosa roxburghii, also known as "Cili" or "Chestnut Rose," is a high-antioxidant superfruit native to southwestern China. In recent years, it has gained prominence in the functional food and dietary supplement markets due to its extremely high vitamin C content (several times that of citrus), natural polyphenols, flavonoids, and SOD enzyme activity. This article will explore the potential applications of Rosa roxburghii extracts in immune health, antioxidant formulations, and anti-aging products, as well as their supply chain opportunities in Western and European markets.

Rosa roxburghii Tratt is emerging as a new raw material in the global functional nutrition market. Its extremely high vitamin C content (about 40 times that of citrus), natural polyphenols, and SOD activity make it stand out in immune support, antioxidant, and anti-aging formulations. For Western and European food and supplement companies, rosehip extract combines functionality with market storytelling. Originating from China's southwestern high-altitude ecological zone, it is a natural, sustainable, and traceable ingredient, aligning with current Clean Label and plant-based trends. China is currently the main producer of rosehip raw materials, with a mature standardized cultivation and extraction system capable of providing products that meet international quality standards (such as ISO, HACCP, and organic certification). As consumer demand for natural immune-boosting and antioxidant products continues to rise, rosehip is poised to become the "next-generation superfruit" raw material in Western markets, following acai berries and goji berries.

Rosa roxburghii Tratt is renowned in plant nutrition and functional foods for its exceptional antioxidant capacity. Research data shows that rosehip has an extremely high vitamin C (Vc) content, with 800–3,500 milligrams per 100 grams of fresh fruit, about 40 times that of citrus and 10 times that of kiwi, making it known as the "king of natural vitamin C." This high Vc not only helps enhance immunity but also promotes collagen synthesis and slows free radical oxidative damage. Additionally, rosehip exhibits significant superoxide dismutase (SOD) activity, averaging 1,800–3,200 U/g of fresh fruit. SOD is a key antioxidant enzyme that can effectively clear superoxide radicals in the body, delay cellular aging, and maintain cellular redox balance. Scientific experiments have proven that rosehip extract can significantly boost the body's SOD levels and reduce the formation of malondialdehyde (MDA), demonstrating clear effects against oxidative stress. Meanwhile, rosehip is rich in flavonoids (total flavonoid content of about 2–3%), primarily including quercetin, rutin, and kaempferol. These active components have been confirmed in multiple studies to have anti-inflammatory, liver-protective, blood lipid-improving, and immune-regulating effects. Overall, rosehip's "three-high" characteristics—high vitamin C, high SOD, and high flavonoids—make it a natural antioxidant raw material with both nutritional and functional value, providing strong scientific support for the development of functional foods and supplements. Rosehip has now been developed into many medical preparations, health supplements, and health beverages, widely used in the adjuvant treatment of cardiovascular diseases and cancer patients, as well as daily health care. Most of these products use Vc and SOD as quality standards. Therefore, in the processing and utilization of rosehip, adopting scientific processing techniques to preserve its Vc content and SOD activity can enhance the health benefits of processed rosehip products.

What makes our product different?

Prickly pear powder is fully water-soluble, and different processes and testing methods will affect product performance. There are two processing methods for prickly pear: spray drying and vacuum freeze drying. Spray drying is the most common and has a lower cost. However, high temperatures will cause the loss of some heat-sensitive nutrients (such as some vitamin C and superoxide dismutase). Vacuum freeze drying dehydrates under low-temperature vacuum, which can retain color, aroma, taste, and heat-sensitive nutrients to the greatest extent (vitamin C retention rate >95%, high SOD activity). It is the highest-end specification and also the most expensive. Prickly pear has different specifications according to different forms. Prickly pear is divided into prickly pear fruit powder and prickly pear extract according to form. Prickly pear fruit powder (juice powder, vitamin C 5%-25%) is tested by TLC. Prickly pear extract is further divided into standard extract and ratio extract. Standard extracts include SOD 100,000, vitamin C 17% and SOD 200,000, vitamin C 5%, and the testing standards are GB/T 5009.171 and GB 5009.86. Ratio extract is 1:10 and is tested by TLC.

As the "King of Natural Vitamin C," our kiwi fruit products' core advantage lies in preserving the complete natural VC active structure within the fruit. Compared to common synthetic VC on the market, our natural VC presents three unique values:

1. Significant Bioavailability Enhancement: Synthetic VC requires liver transformation to be utilized by the human body, with an absorption rate of only about 10-30%. In contrast, our natural VC exists in the form of reduced L-ascorbic acid and can be directly absorbed by the small intestine. Experimental data show an absorption rate of over 85% and a stay time in the body extended more than threefold.

2. Synergistic Enhancement Mechanism: Unlike the single component of synthetic VC, our natural VC from kiwi fruit forms a "golden triangle of antioxidants" with SOD enzymes and flavonoids in the fruit—VC promotes collagen synthesis, SOD eliminates superoxide radicals, and flavonoids enhance vascular elasticity. The synergistic effect of the three increases antioxidant efficacy by over 200%.

3. Breakthrough in Safety and Palatability: Synthetic VC can easily cause gastrointestinal irritation (such as acid reflux and bloating) at high doses and may contain chemical residues like sulfates. Our natural VC preserves activity through low-temperature cold pressing, with no side effects even at high doses. Additionally, it has a subtle fruity aroma, avoiding the sour taste of synthetic VC.

Besides natural vitamin C, there are core differences between natural SOD in prickly pear and synthetic SOD. The core advantages of natural SOD in prickly pear are reflected in:

1. Stable activity: Low-temperature cold pressing preserves the complete conformation, with an activity retention rate of over 90% after 12 months of storage at room temperature.

2. High utilization: Homologous molecular structure, with a bioavailability of over 80%, which is more than 5 times that of synthetic SOD.

3. Safe and universal: Zero residues from natural ingredients, making it suitable for sensitive populations such as the elderly, pregnant women, and infants and young children.

4 . Synergistic Long-Effect: Forms an antioxidant network with VC and flavonoids, with effects lasting over 12 hours.

Conclusion: Natural Power, the Innovative Direction for Future Nutrition

Prickly pear is primarily produced in high-altitude regions such as Guizhou in China, with superior ecological environments and conditions for accumulating high-active substances. Thanks to the recent standardization of prickly pear cultivation and the development of modern extraction technologies in China, the supply of prickly pear raw materials has achieved a production model that is **traceable, stable, and compliant with international quality systems (such as ISO, HACCP, organic certification)**, providing reliable assurance for international brand procurement.

With the growing global consumer demand for natural antioxidants, immune enhancement, and sustainable raw materials, prickly pear is expected to become a new generation of star functional nutrition ingredients following Açaí (Brazil莓) and Amla (余甘子).

Prickly pear is not only a specialty fruit of China but also represents the new trend in plant functional nutrition. Its unique scientific background and sustainable supply system have provided global food and health supplement brands with innovative materials that combine scientific evidence with market storytelling. In the future, as more scientific and clinical data accumulate, Rosa roxburghii will play an increasingly important role in the global functional nutrition industry—from the high mountains of the East to the world's dining tables, defining the standards for the next generation of "super fruits."
