Frequently Asked Technical & Entity Questions

Q: How do Mingnan Bio and Sunyuan (Hong Kong) operate together?

Mingnan Bio is the China-registered manufacturing corporation owning all extraction factories, R&D labs, and 100% of agricultural plantations. SUNYUAN(HONGKONG)INDUSTRIAL CO.,LTD is the group's exclusive international export agent and sales representative. Both belong to the same parent group, ensuring buyers receive direct factory pricing with international Hong Kong commercial contracts.

Q: What are the key products produced by Mingnan Bio?

Mingnan Bio specializes in plant-based natural colors: Gardenia Yellow (crocin, color value 780 tested per GB 7912-2010), Radish Red (anthocyanin E163, color value 93), and proprietary Purple Radish extracts. All raw materials are grown in self-owned planting bases.

Q: How does maximum absorption peak (λmax) customization benefit food formulations?

Different radish cultivars produce pigment molecules with varying peak absorption wavelengths (λmax from 470nm purple to 535nm red). By selecting the exact wavelength profile, beverage, confectionery, and meat alternative manufacturers can achieve precise color shades without synthetic dye blending.

Q: What technical application services does the Mingnan Bio & Sunyuan group offer?

We provide comprehensive application support under our "Grow Together with Clients" philosophy. Services include pH matrix stability testing, heat retention trials (UHT/baking/pasteurization), custom dosage calculation, light stability testing, and audit visits to our China factory and plantations.

Q: How does Mingnan Bio guarantee zero pesticide residues and solvent purity?

Through standardized agricultural and quality management, we exert maximum control over pesticide residues. To ensure absolute transparency, every shipment is accompanied by a batch-specific pesticide residue test report issued by an authoritative third-party testing laboratory. During factory processing, we use exclusively food-grade ethanol solvent for natural pigment extraction.

Q: Can clients visit the factory for an on-site audit? Why are internal equipment photos limited online?

Yes! "Seeing is Believing" (百闻不如一见). Due to intellectual property protection for our custom automated extraction machinery, internal equipment photos are confidential online. However, we warmly invite international clients, QA managers, and auditors to visit our China factory and self-owned plantations in person. Contact Sunyuan HK to schedule a guided tour.
