Hongji Agriculture — Product Grade Comparison Matrix
Introduction
Hongji Agriculture produces a comprehensive range of dehydrated potato products covering multiple grades and specifications to meet the diverse needs of global food manufacturers. This document provides a detailed comparison matrix across our product grades, enabling procurement and R&D teams to select the optimal product for their specific application.
The product portfolio is organized along two axes:
- Product Type: Potato Flakes vs. Potato Powder (60 Mesh)
- Grade Tier: Standard Grade → Premium Grade → Organic/Specialty Grade
Each tier reflects increasing quality control stringency, tighter specification tolerances, and suitability for progressively demanding applications.
