HiSiaddi is an innovative foreign trade service provider driven by dual engines of technology commercialization and foreign trade services. It has established a "1+2+3+4=1" service system and can supply grape seed extracts from multiple well-known original manufacturers. As a foreign trader with R&D capabilities, HiSiaddi has conducted repeated multi-round factory inspections of grape seed extract manufacturers, possessing objective and in-depth insights into different brands. We regularly analyze various grape seed extract manufacturers for clients to help them select matching raw materials. Below is a brand recommendation case.
Contact HiSiaddi customer service for additional brand and model comparative analysis.
Client: NovaCare GmbH, Germany A high-end functional food and skincare raw material brand serving premium health food factories and organic beauty brands across Europe. Core demands included high-purity, low-pesticide-residue, highly stable grape seed extract for its premium antioxidant capsules and anti-aging essence liquids, complying with EU EFSA, cGMP and EC 1881/2006 pesticide residue standards, with strict limits on raw material proanthocyanidin content, monomer ratios, water solubility and microbial counts. The client operated on an ample budget and rejected low-end generic raw materials.
This marked the client’s first procurement from China, with limited familiarity with domestic plant extract brand landscapes. They contacted five major manufacturers (Yichenkang, Panhaiweiyuan, Kangruida, Yunengguan, Lancaogangmu), each exclusively promoting its own products and emphasizing self-advantages while avoiding peer comparisons. Trapped in an information vacuum, the client could not objectively assess brand suitability and delayed supplier selection, commissioning HiSiaddi to conduct neutral brand research, horizontal performance testing and targeted matching recommendations.
The client lacked understanding of China’s mid-to-high-end grape seed extract brand tiers and could not distinguish between high-purity specialty raw materials and mass generic products, making it impossible to match options with its premium formula requirements.
Each of the five manufacturers highlighted separate selling points: Yichenkang emphasized supercritical CO₂ extraction and high OPC levels; Panhaiweiyuan marketed all-round high purity and mature EU compliance; Kangruida prioritized cost performance and stable supply; Yunengguan focused on microcapsule embedding and superior stability; Lancaogangmu specialized in compound formulas and high bioavailability. No manufacturer provided objective analysis of competitor strengths and weaknesses, eliminating a basis for horizontal core indicator comparison.
The client prioritized multiple metrics simultaneously: proanthocyanidins ≥95%, OPC ≥85%, water solubility ≥98%, EU 200-item pesticide residue screening, and 12-month activity retention ≥95%, yet lacked clarity on each brand’s respective strengths and weaknesses across these dimensions to inform decision-making.
Every brand offered 2–3 mainstream models (high-purity powder, water-soluble powder, stabilized powder). The client could not identify which variants suited capsule production versus essence liquid formulation, fearing incorrect selection would compromise finished product quality.
HiSiaddi assembled a cross-functional team of plant extract technicians, EU compliance specialists and formula application experts, breaking the industry norm of only promoting cooperative manufacturers. We conducted neutral research on five mid-to-high-end brands (Yichenkang, Panhaiweiyuan, Yunengguan, Kangruida, Lancaogangmu), completing factory site visits, sample testing and qualification verification. Horizontal comparative reports were compiled across five dimensions: core active ingredients, production technology, application compatibility, compliance capacity and price brackets.
