Did You Know Your Potato Chips Use Design of Experiments? ππ€―
β
Wait⦠what? Potato chips using Design of Experiments (DoE)? Well, not the chips themselves, of course! But behind the scenes, DoE plays a crucial role in perfecting the production process of your favorite crispy snack.
β
Letβs take Pringles as an example. These well-known stacked chips arenβt just made from potatoes; they come from a carefully crafted mix of ingredients like corn, wheat, rice, and potatoes. Since the availability and quality of raw materials change frequently, how do manufacturers ensure consistent taste, texture, and crunch every time?
β
The answer lies in experimental planning β a smart and efficient method for data collection. It helps producers understand ingredient interactions and tweak recipes without compromising quality.

The Goal: Perfecting the Chip Recipe
β
One key challenge in the potato chip industry is replacing part of the potato flakes with rice flour while ensuring that the chips maintain their delicious properties. This optimization process requires seven controllable mixture inputs (ingredients) and four uncontrollable factors (external influences).
Controllable Ingredients:
- Potato flakes (22.6% - 60%)
- Wheat starch (0% - 20.7%)
- Parboiled rice flour (0% - 34.5%)
- Extruded rice flour (0% - 34.5%)
- Corn flour (0% - 34.5%)
- Maltodextrin solution (30% - 40%)
- Emulsifier (1% - 3.1%)
β
Uncontrollable Inputs:
- Wheat starch conductivity (%)
- Fatty acid content in wheat starch (%)
- Maltodextrin solution turbidity (NTU)
- Moisture content in parboiled rice (%)

Defining the Perfect Chip
β
To maintain consistency, manufacturers set specific product quality attributes and target values:
β
Lipid content should be minimized (must stay below 15%).
β
Crisp weight should fall between 2 β 2.2g per chip.
β
Stack height should be within 95 β 105mm to ensure uniformity.
β
Moisture content should be minimized (max of 2.5% to maintain crispiness).

How DoE Helps Achieve the Best Recipe
β
By using EFFEX software and OMARS designs, potato chip manufacturers can efficiently test different ingredient combinations and analyze the results without excessive trial and error. DoE allows them to:
β Optimize ingredient proportions for the perfect taste and crunch.
β Understand interactions between ingredients to maintain chip quality.
β Reduce waste by avoiding unnecessary experiments.
β Ensure every batch of chips meets quality specifications.
