▎ What Is Hot-Air Dried Spinach Powder?
Hot-air dried spinach powder is produced by washing, blanching, and air-drying fresh spinach leaves before milling them into a fine, free-flowing powder at 80–120 mesh. Unlike freeze-dried versions, hot-air drying offers a cost-effective solution for high-volume applications while still preserving the vegetable's signature green color, mild earthy flavor, and core nutritional profile — particularly its non-heme iron content (~20% DV per 10g serving), vitamin K (~400% DV), lutein/zeaxanthin for eye health, and dietary fiber (~25–30%). The result is a shelf-stable, easy-to-handle ingredient that delivers "hidden greens" nutrition without the supply-chain complexity of fresh produce.

▎ Why Formulators Choose FOGT Spinach Powder?
✓ Natural Green Colorant: Chlorophyll-rich powder provides a clean-label alternative to synthetic FD&C Green No.3 and tartrazine. Delivers soft-to-vivid emerald hues in pasta, bakery, dairy, and confectionery without E-number declarations.
✓ Iron & Vitamin K Powerhouse: Among the most nutrient-dense vegetable powders available. One 10g serving delivers ~20% of daily iron needs and up to 400% of vitamin K — supporting blood health, bone metabolism, and energy formulation claims.
✓ Lutein & Zeaxanthin for Eye Health: Contains 6–8 mg lutein per 100g (retained through controlled hot-air drying). Positions finished products in the functional eye-health space — increasingly relevant for aging populations and screen-heavy consumers.
✓ High Fiber, Clean Label: ~25–30% dietary fiber by weight enables "good source of fiber" nutrition claims. Single-ingredient declaration ("spinach") aligns with consumer demand for recognizable, additive-free labels.
✓ Cost-Effective AD Process: Hot-air drying delivers competitive unit economics versus freeze-drying for applications where maximum vitamin retention is not the primary purchase driver. Ideal for large-volume pasta, sauce, pet food, and savory snack formulations.
▎ From Fresh Spinach to Shelf-Stable Powder
Our spinach powder follows a controlled 7-step production process designed to maximize color retention, ensure microbiological safety, and deliver consistent particle distribution:
1. Raw Material Sorting Fresh spinach leaves inspected for variety, maturity, and absence of foreign matter. Rejected leaves diverted to non-food use.
2. Washing & Cutting Multi-stage water wash removes soil and surface contaminants. Leaves trimmed to uniform size for even drying.
3. Blanching Brief heat treatment (85–95°C, 1–3 min) inactivates enzymes (peroxidase, polyphenol oxidase) that cause color degradation and off-flavors during storage.
4. Draining & Spreading Excess water removed via centrifugal drainage. Blanched leaves spread evenly on drying trays at controlled bed depth.
5. Hot-Air Drying Continuous belt dryer at 60–80°C until moisture reaches ≤12%. Temperature profile optimized to minimize chlorophyll degradation while achieving target moisture.
6. Milling & Sieving Dried leaves milled through stainless-steel hammer mill, then sieved to 80–120 mesh specification. Oversize particles re-milled; fines recycled.
7. Metal Detection & Packing Final product passes through ferrous/non-ferrous metal detector. Packed in food-grade aluminum-laminated bags (25 kg net) into corrugated cartons.

▎ AD vs. FD Spinach Powder: Which Fits Your Formulation?
Understanding the trade-offs between hot-air dried (AD) and freeze-dried (FD) spinach powder helps you select the right grade for your application and budget:
Attribute | Hot-Air Dried (This Product) | Freeze-Dried (FD) |
Vitamin C Retention | Lower (≥20% loss) | Higher (≤90% retained) |
Chlorophyll / Green Color | Good (slightly darker olive tone) | Excellent (vivid bright green) |
Iron / Mineral Content | Fully retained | Fully retained |
Rehydration Speed | Moderate (2–3 min) | Fast (<30 sec) |
Unit Cost | $≤1.5–2.0/kg (bulk) | $≤4–6/kg (bulk) |
Best For | Pasta, bakery, sauces, pet food, | Premium smoothies, instant drinks, |
Shelf Life | 12 months | 18–24 months |
Water Solubility | Partial (suspends well) | High (dissolves readily) |
▎ Recommended Applications & Usage
▶ Pasta & Noodles: Add 2–4% to dough for natural green pasta (spinach fettuccine, tagliatelle, ramen). Pairs beautifully with cream-based and pesto sauces. Replaces synthetic green colorants entirely.
▶ Bakery: Incorporate 1–3% into bread, muffin, pancake, and cracker formulas for "green superfood" positioning. Works in both yeast-leavened and chemically-leavened products.
▶ Functional Beverages: Blend into green smoothies, protein shakes, and RTD health drinks. Earthy flavor profiles pair well with banana, mango, pineapple, and citrus notes.
▶ Sauces, Dips & Soups: Natural thickener and color enhancer for pesto, guacamole, hummus, green curry pastes, and vegetable soups. Adds umami depth alongside visual appeal.
▶ Pet Food & Treats: Provides natural green color plus micronutrient boost in dog/cat treats and kibble coatings. Chlorophyll supports oral health claims in pet nutrition marketing.
▶ Supplements & Nutraceuticals: Key ingredient in green superfood blends, multivitamin capsules, and iron-fortification formulas. High fiber content supports digestive health positioning.
▶ Infant & Baby Food: Mild flavor and iron content make it suitable for fortified baby cereals and toddler meals. Always verify oxalate levels for kidney-sensitive formulations (CoA available on request).
Formulation Tip: For applications requiring brighter green color or higher vitamin C retention, consider our Freeze-Dried Dragon Fruit Powder (for magenta-green blends) or pair with Beetroot Powder for dual-color natural pigment systems.

▎ Frequently Asked Questions
Q: Is this 100% pure spinach powder?
A: Yes. Our product contains only spinach (Spinacia oleracea) with no fillers, carriers, anti-caking agents, or artificial additives. The single-ingredient declaration supports clean-label positioning.
Q: What is the difference between your AD spinach powder and freeze-dried?
A: Hot-air drying is more cost-effective and ideal for large-volume applications (pasta, bakery, pet food) where moderate color retention suffices. Freeze-drying preserves more heat-sensitive vitamins (especially vitamin C) and delivers brighter green color, but at 2–3x the unit cost. This product uses the AD process.
Q: Can you customize the mesh size?
A: Yes. While our standard specification is 80–120 mesh, we can produce finer (up to 200 mesh) or coarser (down to 40 mesh) grades based on your application requirements. Custom orders may have different MOQ and pricing.
Q: Does spinach powder contain high levels of oxalates?
A: Spinach naturally contains oxalates — this is an inherent characteristic of the leafy vegetable, not introduced by processing. We provide exact oxalate levels on the CoA upon request so your R&D team can calculate dietary intake for specific formulations, especially for "low-oxalate" or kidney-care positioning.
Q: How does it perform as a natural green colorant?
A: The chlorophyll content delivers soft-to-moderate emerald green hues. For vivid green results, use at 2–4% inclusion in light-colored matrices (pasta dough, white cake batter, cheese). Color stability is best at pH 6–8; avoid prolonged exposure to high heat (>120°C) or acidic conditions (pH <4) which accelerate chlorophyll degradation to pheophytin (olive-brown).
Q: What certifications do you hold?
A: Our facility operates under Q/JSZY 0007S standard with HACCP and ISO 22000 certification. Kosher, Halal, Organic (EU/USDA/NOP), and Non-GMO Project verification can be arranged for custom orders. All export shipments include required documentation for destination market compliance.
