Exploring the surging global market demands driven by clinical digestion health research, functional clean-label food trends, and advanced cosmetic innovations.
The global pharmaceutical and nutraceutical sectors are experiencing a massive pivot toward natural digestive catalysts. Actinidin, a highly potent sulfhydryl protease found uniquely in Kiwi Extract (derived from Actinidia deliciosa and Actinidia chinensis), is at the center of this revolution. Unlike synthetic enzymes, actinidin naturally facilitates the breakdown of complex dietary proteins (such as gluten, casein, and muscle fibers) across wide pH ranges, significantly improving gut transit times and alleviating systemic bloating. Wholesale buyers are increasingly incorporating standardized kiwi powders to satisfy the rigorous clean-label requirements of modern, health-conscious consumers.
Beyond gastrointestinal efficacy, industrial research recognizes Kiwi fruit extract as a dual-action powerhouse for dermatological formulations. It naturally contains a high density of polyphenols, ascorbic acid, and potassium, which synergize to neutralize free radicals, block intracellular melanin synthesis, and restore skin barrier lipids. Furthermore, the soluble and insoluble fiber fractions within the extract act as optimal prebiotics for the skin microbiome, boosting topical immunology. Consequently, modern premium cosmetics manufacturers are demanding raw, pesticide-free bulk extracts for organic anti-aging creams and clarifying serums.
From an industrial perspective, raw kiwi pulp is highly unstable, prone to enzymatic degradation, thermal spoilage, and seasonal nutrient fluctuations. For global brands, selecting a wholesale partner capable of stabilizing actinidin activity (expressed in U/g) and maintaining a reliable, standardized level of naturally occurring Vitamin C is critical. This is where advanced bio-tech extraction companies like Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) bridge the gap, implementing strict molecular stability controls that protect bioactive integrity during large-scale manufacturing processes.
To achieve high-potency Kiwi Extract suitable for clinical formulations, Nanjing Tong Rui Bio-Tech (TRB) employs a multi-stage, low-temperature vacuum extraction and separation pipeline. Keeping the process thermal footprint minimal is vital to prevent the denaturation of heat-sensitive enzymes (actinidin) and the degradation of ascorbic acid.
The tech process begins with high-quality, sustainably harvested kiwi raw fruits. The fruits undergo gentle washing and cold-press juice extraction. To remove structural fibers and unwanted starches without chemical solvents, we apply a cascade of ultrafiltration membranes. The clarified liquid is concentrated at low temperatures and then freeze-dried or low-temperature spray-dried with premium maltodextrin carriers to guarantee optimal flowability, solubility, and bulk density.
Our kiwifruits are sourced from dedicated orchards with strictly monitored soil quality, ensuring trace heavy metals and zero pesticide residues. This fundamental vertical integration allows TRB to trace each batch back to its geographical planting plot, offering comprehensive documentation to international buyers.
We analyze enzyme kinetics using HPLC and spectrophotometric assay protocols to measure standardized digestion units. Whether you require actinidin activity at 10,000 U/g, 20,000 U/g, or custom configurations, our laboratories ensure precise batch-to-batch repeatability and consistency.
For brands targeting pure labels, we provide organic acacia fiber or organic brown rice flour as substitute carrier agents. This ensures that the finished ingredient qualifies for USDA Organic, EU Organic, Non-GMO Project Verified, and clean-label declarations.
Over two decades of pioneering bioscience, leading the global market with award-winning health ingredients.
Established as a specialized technological enterprise combining research, design, production, and international sales, Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has stood as a pioneer in the plant extract sector for more than 20 years. Our unwavering focus on scientific rigor has earned us the prestigious 2026 "Global Biotechnology and Life Sciences Award" - honoring TRB as the ''Best Global Herbal Extract Provider 2026''.
We operate three dedicated, state-of-the-art factories: one specializing in high-purity botanical/herbal extracts, one dedicated to bee product extraction, and a specialized facility for animal-derived bioactive compounds. This multi-industrial layout allows us to serve diverse formulation challenges with unparalleled raw material versatility.
In recent years, our primary R&D focus has expanded into cognitive health and longevity. We develop cutting-edge nootropics, brain health supports, and anti-aging compounds that complement our fruit and vegetable powders to offer full-spectrum wellness solutions.
To support high-stakes compliance environments, all our production facilities operate under strict compliance with current Good Manufacturing Practices (cGMP). Our analytical laboratories are equipped with HPLC, GC-MS, and ICP-MS systems to monitor heavy metals, microbiological loads, and active chemical profiles.
Our comprehensive certification suite includes: GMP, ISO, HACCP, ORGANIC, FDA registered facility status, HALAL, and KOSHER Certificates. These credentials guarantee smooth customs clearances, reducing time-to-market and compliance overhead for major manufacturers in the US, Europe, and Asia.
How local logistical infrastructure, geographical sourcing, and technological scale ensure consistent bulk pricing and uninterrupted international deliveries.
China is home to some of the largest kiwifruit growing corridors globally. By establishing long-term contract farming partnerships and utilizing highly localized crop supply chains, TRB bypasses raw material price volatility. The sheer volume of domestic crop availability guarantees stable bulk unit pricing for wholesale buyers, even during localized crop shortages elsewhere.
Operating from our primary base in Nanjing (Pioneer Bio-Park), we benefit from China's highly developed transportation networks. Direct connectivity to deep-water shipping lanes in Shanghai and Ningbo, combined with integrated rail networks to Central Asia and Europe, ensures multi-modal shipping options. This reduces transit times, minimizes freight expenses, and protects cargo integrity.
Our production facilities run high-throughput continuous extractors and PLC-controlled drying columns. Automation minimizes labor variability, controls energetic footprints, and delivers a production capacity that can scale up seamlessly to handle multi-ton contract manufacturing orders on short notice.
Adapting kiwi botanical applications to meet local market needs and consumer preferences across North America, Europe, and the Asia-Pacific region.
Dietary Supplement Regulations: In the US, our Kiwi Extract matches FDA requirements under DSHEA guidelines. Manufacturers primarily format the extract into prebiotics, high-potency enzyme complexes, chewable dietary gummies, and powder drink mixes focusing on gut wellness. Standardized low-heavy-metal counts are essential to meet California Proposition 65 requirements.
Novel Foods & Organic Directives: European buyers prioritize EFSA-compliant ingredients, strictly clean-label extraction profiles, and pesticide-free status. TRB offers certified organic kiwi powders matching EU organic standards. Our solvent-free aqueous extraction methods are fully compliant with EU directive requirements for dietary and food supplements.
Cosmeceuticals & Nutricosmetics: Within the East Asian markets, kiwi powder is highly valued for skin-whitening, deep hydration, and nutritional support. We support local formulations with Halal and Kosher certified options, catering to regional market needs and ensuring seamless acceptance across Southeast Asian countries.
How TRB is driving innovation through molecular engineering, enzyme stabilization, and ecological sustainability.
To extend the shelf-life and biological availability of actinidin within multi-ingredient dietary formulas, our laboratory is scaling up its microencapsulation pipeline. By wrapping actinidin and delicate vitamin components in natural lipid or alginate matrices, we shield them from gastric juices, facilitating targeted release directly into the small intestine where protein digestion occurs.
By integrating real-time automated monitoring systems across our extraction loops, we are targeting a further 30% reduction in water and energy usage by 2028. This predictive modeling system dynamically adjusts membrane pressures and concentration speeds based on real-time feedback from the extraction stream. This data-driven approach keeps production yields optimized and helps protect the native structure of delicate botanical compounds.
