Test center is equipped with first-class testing equipment and experimental environment, which is available for a range of test items, including molecular weight, amino acids, heavy metals，pesticide residues and various microorganisms, to ensure the safety and stability of product quality.

Zhejiang Pingtairong Biotechnology Co., Ltd. has functional marine peptide production lines with proprietary intellectual property rights. The production line incluedes marine biological pretreatment system, biological response system, protein and peptide grading system and drying system.

The raw materials for the production of the tuna series health products are sourced from the deep ocean, and all the tuna used are caught by professional long-distance tuna longline fishing boats and returned to China through a cold chain logistics system. The group has a large-scale specialized ocean fishing fleet with international first-class standards and a 6000 ton ocean going ultra-low temperature transportation fleet with storage temperatures reaching -60 ℃. Relying on global marine biological resources, the group integrates multiple resources and continues to promote industry university research cooperation. It has taken new steps in the field of marine biology, especially in the tuna functional food series, achieving the goal of functionalizing and compounding marine food functional foods, and contributing to a healthy China by 2030.
