When it comes to manufacturing crispy, golden potato chips, not just any potato will do. For chips, whether for domestic snack markets or for export, the right potato variety and quality attributes are critical. At Potato Exporters we understand that processors need potatoes that deliver consistency, crunch, and excellent yield.
What Potato Processors Look For
• High Dry Matter Content
Dry matter (mostly starch) is the single most important criteria for chips potatoes. Processable potatoes typically have a dry matter content of above 20 percent, ideally around 22–25%. Potato Business+2Pakistan Business Council+2
Higher dry matter means:
More chips yield per kilogram of raw potato
Less oil absorption during frying (lower cost, better profit)
Better texture and crispiness in final product
On the other hand, “table potatoes” (for boiling or regular cooking) usually have lower dry matter, often under 15%, making them unsuitable for chips production.
• Low Reducing Sugars & Asparagine
Reducing sugars contribute to dark browning and inconsistent color in fried chips. Potatoes for chips should have low reducing sugar content (ideally under threshold levels) to ensure a light golden colour after frying.
Low asparagine + low sugar reduces the risk of harmful compounds formed during frying (e.g. acrylamide), which is crucial for food safety and export quality.
• Right Size, Shape & External Quality
Shape: Round to round-oval tubers are preferred for uniform slicing.
Size: Ideally tubers with diameter around 40–60 mm (or in general, 45–85 mm) are preferred for efficient processing.
Low asparagine + low sugar reduces the risk of harmful compounds formed during frying (e.g. acrylamide), which is crucial for food safety and export quality.
• Good Storage & Stability
For large-scale processors and exporters — seasonal availability and storage stability matter. Potatoes that keep their quality (low sugar accumulation, stable dry matter) during storage are preferred, especially when supply must meet demand year-round.
Varieties Commonly Used for Chips
Several potato cultivars worldwide are specifically bred or known for ideal chips/frying properties. Some of the top-performing varieties include:
- Atlantic potato: Widely used for potato chips processing thanks to its high solids, good processing quality and suitable tuber shape.
- Russet Burbank: A classic variety, popular especially in North America. Its dry, mealy flesh and high starch make it ideal for fries and chips.
- Superior potato: Known for good chipping quality and medium-to-high yields, though it performs best under cooler climates.
- Other industrial-grade varieties: e.g. Lady Rosetta, Hermes potato, Lady Claire potato, frequently used in commercial crisping industry, thanks to their high dry matter, low sugar, uniform shape and stable storage behaviour.
Why It Matters for Exporters & Chips Manufacturers (Including You)
If you’re supplying potatoes for chips production — whether locally or for export — aligning your supply with the processing standards above is essential. Here’s why:
Quality & Consistency: Chips producers need consistent quality; off-spec potatoes (low dry matter, high sugars, odd shapes) lead to poor yield, dark chips, high oil absorption, and customer dissatisfaction.
Cost Efficiency: High-dry-matter potatoes give more chips per ton, reduce frying oil consumption, and lower wastage — boosting profitability.
Market / Export Standards: For export markets, especially in Europe or elsewhere, processors often test raw potatoes for starch content, sugar levels and chemical safety (e.g. acrylamide precursors). Meeting these standards makes your produce more desirable.
Year-Round Supply: By offering industrial‐grade potatoes that store well (or sourcing seasonally appropriate varieties), you become a reliable supplier for chips factories — adding value to your export proposition.
