IQF Frozen Chinese Yam Slices for Hot Pot, Foodservice and Food Processing
GreenLand-food supplies IQF Frozen Chinese Yam Slices for global importers, Asian food distributors, hot pot chains, restaurant suppliers, central kitchens, ready meal factories, frozen vegetable brands and retail private label programs. We prepare selected Chinese yam through washing, peeling, trimming, slicing, optional color protection according to order requirement, IQF freezing and frozen packing.
Common slice thickness options include 5-12mm or customized specifications. Before quotation, we confirm slice thickness, diameter, color, broken slice tolerance, peeled status, packaging format and document requirements according to your market and final application.
In international B2B sourcing, Frozen Yam Slice may also be searched as IQF frozen sliced yam, frozen Chinese yam slices, skin-off frozen white yam, IQF yam cuts, frozen yam slices for hot pot or frozen yam for foodservice and food processing.
Product image helps review slice appearance, peeled surface, color and frozen condition before sample approval.
Chinese Yam, White Yam or Other Root Vegetables?
Different markets use the word yam for different root vegetables. Before quotation, GreenLand-food confirms the exact raw material, processing method, cut style, packing and final application so your order does not mix Chinese yam slices with other root vegetable products.
| Product Type | Key Feature | Buyer Channel |
|---|---|---|
| IQF Chinese Yam Slices | Peeled white yam slices, skin-off, IQF frozen | Hot pot, soup, ready meals, foodservice, retail packs |
| IQF Yam Cuts | Segments, chunks, slices or customized cuts | Food processing, central kitchen, frozen vegetable mixes |
| Whole Fresh Chinese Yam | Fresh whole root, not IQF frozen | Fresh produce channels |
| Frozen Sweet Potato | Different root vegetable with orange, yellow or purple flesh | Retail, foodservice, ready meals |
| Frozen Taro | Different root vegetable with different texture and flavor | Asian foodservice and retail |
| Frozen Cassava / Tapioca | Different root vegetable with different processing and application | Industrial processing and ethnic food channels |
Our quotation scope here is IQF Frozen Chinese Yam Slices. If your order needs fresh whole yam, yam chunks, sweet potato, taro or cassava, we should confirm the product identity, specification and quotation separately.
Available Yam Forms, Slice Thickness and Cut Options
For frozen yam slices, the most important procurement details are peeled status, slice thickness, diameter, broken slice tolerance, color and packaging. We match the form to hot pot, soup, foodservice, ready meal, retail or industrial processing needs.
| Product Form | Suggested Specification | Application |
|---|---|---|
| Yam Slices | Thickness 5-8mm | Hot pot, soup, retail packs, quick cooking |
| Yam Slices | Thickness 8-12mm | Foodservice, central kitchen, stews, ready meals |
| Yam Chunks | 20x20mm, 30x30mm or customized | Soup, stew, ready meals, industrial processing |
| Yam Segments | 3-5cm, 5-7cm or customized | Foodservice, central kitchen, bulk cooking |
| Yam Dice | 10x10mm, 15x15mm or customized | Mixed vegetables, ready meals, food factories |
| Yam Strips | Customized | Restaurant supply, prepared dishes |
| Broken / Industrial Grade | Controlled broken pieces | Soup base, puree, paste, industrial use |
Thin slices work well for hot pot and quick cooking. Thicker slices and segments are more practical for foodservice, soup, stew and central kitchen use. Dice and industrial pieces support ready meals, mixed vegetables and food processing.
Cut-form image helps compare chunks, slices and frozen appearance for foodservice programs.
Yam piece photo supports discussion of customized cuts, broken tolerance and industrial processing use.
