Why We Supply IQF Peeled Chestnuts for B2B Orders

Pre-peeled IQF chestnuts reduce labor for foodservice kitchens, central kitchens and food manufacturers. Individual quick freezing helps keep pieces separate, so your team can portion, weigh and pack more efficiently.
We match whole, diced, broken and processing grades to the application instead of offering one generic specification, so your purchasing team can control cost, appearance, texture and production performance.
Chestnuts naturally contain starch, fiber and a mild sweet nutty flavor, making them useful for sweet and savory food applications. We support the order with commercial quality control, packing, documents and cold chain handling.
From Fresh Chestnuts to IQF Frozen Peeled Chestnuts
We select mature, full chestnuts and remove raw material with visible insect damage, mold, black spots or severe breakage.
We wash the shell surface and sort by size to improve peeling and finished product consistency.
We score or cut the shell before heat treatment so the shell and inner skin can be removed more effectively.
Steam or blanching treatment supports shell removal, inner skin control and texture preparation before freezing.
We control inner skin residue because it affects appearance, mouthfeel and downstream processing.
Manual or optical sorting removes black-spotted, moldy, insect-damaged, heavily broken and off-spec pieces.
Individual quick freezing reduces clumping and supports portion control for bulk, foodservice and retail packing.
We inspect finished product, run metal detection, pack by batch and keep frozen storage at -18°C or below.

Quality Points to Confirm Before Ordering IQF Chestnuts
| Control Point | Why It Matters |
| Peel cleanliness | Inner skin residue affects appearance, texture and finished product acceptance. |
| Whole rate / broken rate | Grade, cost and application depend on how much whole or broken material is accepted. |
| Insect damage | Chestnuts require strict raw material selection and sorting to reduce internal defect risk. |
| Mold and black spots | These defects can affect food safety, color and customer complaints. |
| Texture after cooking | Bakery, dessert, ready meal and foodservice products need stable bite and structure. |
| Color consistency | Over-dark or blackened pieces reduce grade and visual value. |
| Size uniformity | Consistent size supports dosing, packing, heating and industrial production. |
| Free-flowing IQF condition | Low clumping improves weighing, repacking and continuous processing. |
| Ice crystal and glazing control | Controlled frozen condition helps reduce net weight disputes and block formation. |
| Foreign material control | Shell pieces, inner skin, stones and metal must be controlled before shipment. |
| Microbiological control | Food manufacturers and importers can request batch testing according to the order. |
| Aflatoxin testing | Testing can be arranged according to destination market and buyer requirements. |
| Cold chain stability | Temperature fluctuation can cause clumping, texture decline and quality claims. |
Mold, Insect Damage, Aflatoxin and Labeling Support
We inspect chestnuts for mold, insect damage, black spots and abnormal odor before and after peeling. Sorting after shell and inner skin removal is important because internal defects become more visible at that stage.
Aflatoxin testing, pesticide residue testing, heavy metal testing and microbiological testing can be arranged according to destination market and buyer requirements. Each required batch can be linked with COA and inspection documents.
Ingredient declaration, allergen statement and label wording should be confirmed according to the destination market before retail or private label packaging is printed. We can prepare document support according to your order and artwork requirements.
