Hongji Potato Powder (60 Mesh) — Technical Datasheet

Product Overview

Hongji Agriculture's Potato Powder (60 Mesh) is a finely milled dehydrated potato product produced from high-solids processing potato varieties including Atlantic, Shepody, and Russet Burbank. Unlike Potato Flakes (which retain a flake-like physical structure), Potato Powder is milled through a 60-mesh (250 μm) screen, resulting in a free-flowing fine powder with rapid hydration, uniform particle size distribution, and excellent blending properties.

Potato Powder is the preferred ingredient for dry-mix applications (instant soup bases, seasoning blends, bakery premixes), extruded snacks, batter systems, meat binders, and nutritional supplements where uniform dispersion and rapid solubility are critical. The finer particle size provides faster hydration kinetics and smoother finished texture compared to standard flakes, making it the ingredient of choice for applications requiring seamless integration into dry blends and batters.


1. Raw Material & Processing

1.1 Raw Potato Varieties

Variety Dry Matter (%) Starch (%) Reducing Sugars (%) Contribution
Atlantic 20–22 16–18 ≤ 0.15 Light color, neutral flavor
Shepody 19–23 15–17 ≤ 0.12 Premium texture, high yield
Russet Burbank 20–24 16–20 ≤ 0.20 High starch, rich mouthfeel
Innovator 20–23 16–18 ≤ 0.10 Dual-purpose, excellent color stability

1.2 Raw Material Quality Criteria

Parameter Acceptance Limit Test Method
Dry matter content ≥ 19.0% Underwater weight method
Reducing sugars (fresh weight) ≤ 0.25% DNS colorimetric method
Mechanical damage / rot / greening ≤ 5.0% by weight Visual inspection
Tuber diameter (minimum) ≥ 40 mm Grading sieve
Soil / extraneous matter ≤ 2.0% by weight Wash-weigh method
Sprouting None Visual inspection

Variety selection note: For potato powder destined for cold-water soluble applications (e.g., instant soup bases), Atlantic and Innovator varieties are preferred due to their lower reducing sugar content, which minimizes Maillard browning during drum drying.

2. Manufacturing Process

2.1 Process Flow

Raw Potatoes → Washing & Destoning → Steam Peeling → Inspection & Trimming →
Slicing (8–12 mm) → Blanching (70°C, 12 min) → Steam Cooking (100°C, 30 min) →
Mashing → Drum Drying → Flaking → Pre-crushing → Hammer Milling →
Air Classification → Sieving (60 Mesh) → Metal Detection → Packaging

2.2 Detailed Process Parameters

Process Step Parameters Purpose
Washing & destoning Rotating drum washer, 20 m³/h water flow Remove soil, debris, stones
Steam peeling 12–15 bar, 20–30 seconds Rapid skin removal, minimal cook loss
Inspection Manual sorting on conveyor belt Remove defective tubers and peel remnants
Slicing Slices 8–12 mm thickness Uniform cooking surface area
Blanching Hot water, 70°C, 12 minutes Enzyme inactivation (polyphenol oxidase, peroxidase), leaching of reducing sugars
Steam cooking Atmospheric steam, 98–100°C, 25–35 minutes Complete starch gelatinization, tissue softening
Mashing Rotary masher or roller mill, ≤ 3 mm gap Homogeneous mash without excessive cell rupture
Drum drying Single drum, 160–175°C surface, 15–25 sec residence Rapid dehydration to ≤ 6.0% moisture
Flaking Doctor blade, flake breaker Separate dried sheet into manageable flakes
Pre-crushing Knife mill, 5 mm screen Reduce flake size for hammer mill feed
Hammer milling 3,000–4,000 RPM, 250 μm screen Grind to target particle size
Air classification Cut point: 250 μm Remove ultra-fine fraction (< 75 μm) if needed
Sieving 60 mesh (250 μm) stainless steel, vibratory Ensure ≥ 95% passing 60 mesh
Metal detection Fe ≥ 0.5 mm, SUS ≥ 1.0 mm, Non-Fe ≥ 0.8 mm Contaminant rejection with auto-ejection

Critical Quality Point — Hammer Mill Speed: The hammer mill speed of 3,000–4,000 RPM is optimized to produce the target particle distribution. Speeds above 4,500 RPM generate excessive fines (< 75 μm), which increase dust generation and hygroscopicity. Speeds below 2,500 RPM yield insufficient throughput and a coarser fraction requiring recirculation.

12. Storage & Shelf Life

Condition Specification Notes
Shelf life (unopened, standard packaging) 24 months from production date At optimal conditions
Shelf life (vacuum-packed) 36 months from production date Reduced oxidation, no moisture ingress
Storage temperature ≤ 25°C (optimal: 15–20°C) Lower temperatures extend shelf life
Relative humidity ≤ 60% Powder is more hygroscopic than flakes
Pallet stacking max. 4 pallets high 5+ pallets risks compression and caking
After opening Reseal immediately, use within 2 weeks Moisture pickup accelerates rapidly
Avoid Direct sunlight, moisture ingress, temperature fluctuations Cycling > ±5°C/day degrades quality
Odor absorption Store away from strong odors High surface area absorbs volatile compounds

⚠ Important: Due to its higher surface area-to-volume ratio, Potato Powder is significantly more hygroscopic than Potato Flakes. Once a bag is opened, it must be resealed tightly and stored in a dry environment (≤ 60% RH). In high-humidity conditions (> 70% RH), powder can begin caking within 24–48 hours of exposure.

12.1 Accelerated Shelf Life Data

Storage Condition Time to Quality Limit Key Failure Mode
25°C / 60% RH 24 months Color darkening (ΔE > 3.0)
30°C / 70% RH 10 months Caking, moisture > 6.5%, flow reduction
40°C / 80% RH 5 months Browning (Maillard), off-flavor development
−18°C (frozen) 60+ months Excellent stability, no significant change
