From Farm to Table
Quality Commitment Across the Entire Industry Chain

Carefully selected healthy ingredients, dedicated agricultural cultivation, stable production processes, high-quality products, a comprehensive quality management system, and full-chain traceability — this is the mission ZHAORI Foodstuffs has always upheld.

We are not simply selling products; we are presenting the entire transparent “from farm to table” process to you.

  • Carefully Selected Healthy Ingredients

Sweet potatoes are rich in dietary fiber, vitamins C and E, and potassium, while being extremely low in fat. They also contain unique mucin proteins that help maintain arterial elasticity.

To fully utilize these nutritional advantages, ZHAORI established virus-free seedling laboratories, propagation rooms, and seedling greenhouses. Through cooperation with research teams from China Agricultural University and Qingdao Agricultural University, virus-free healthy seedlings are cultivated using shoot-tip detoxification technology, ensuring nutrition and taste from the source.

  • Deep Agricultural Cultivation

The hilly region of Shandong has an ideal climate and fertile soil, making it a golden area for sweet potato cultivation.

ZHAORI owns approximately 8,000 mu of planting bases, including 4,300 mu of organic sweet potato bases and 3,700 mu of standardized bases, all managed according to GLOBAL G.A.P. standards.

Unified seedling supply, field management, pest control, fertilization, harvesting, and transportation.

  • Stable Production Process

The company has introduced advanced Japanese processing equipment and automatic packaging lines. From washing, steaming, peeling, cutting, drying, trimming to packaging, all processes follow Japanese export standards with no additives used throughout.

The total microbial count is far below national standards, reaching less than 1,000 CFU per gram.

  • Quality Management System & Full Traceability

We have established a product quality traceability system. Through this system, all information from raw material cultivation to finished product delivery can be inquired for any product, realizing the full-process traceability “from field to customer’s hands”.

Triple safety monitoring to strictly control quality .

1. Factory self-inspection: Each key production link is inspected step by step, ensuring greater safety and peace of mind. 

2. Third-party institution inspection: Relying on third-party testing institutions to assess product quality, making it more credible. 

3. Official institution submission: Regular submission to official institutions for inspection, ensuring more authoritative quality supervision.
