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:

  1. Product Type: Potato Flakes vs. Potato Powder (60 Mesh)
  2. 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.


1. Product Grade Overview

Grade Tier Production Emphasis Quality Control Level Price Index Applications
Standard Grade Cost-efficient bulk production Standard in-process & final QC Baseline (100) Bakery, snacks, soups, sauces, meat fillers
Premium Grade Consistent color, finer particle control Enhanced QC, additional color & particle tests +15–25% Instant mash, premium snacks, baby food, exports to EU/NA
Organic Grade Organic-certified raw material, dedicated line Full organic certification audit trail +40–70% Organic-labeled products, clean-label premium brands
Specialty Grade Custom specification Customer-specific QC protocol Custom Contract manufacturing, proprietary blends
