Potato granules
Description
Potato granules are a dehydrated product made by cooking, mashing, drying, and granulating potatoes.
They appear as a coarse, off-white to light-yellow powder with the typical aroma and taste of cooked potato.
Commonly used as a base or texturizer in mashed potatoes, snacks, bakery items, soups, and industrial recipes.

Residual moisture: 6–8%
Bulk density: ~0.6–0.8 g/cm³
Dispersibility: readily rehydrates in hot water
pH (1% solution): 5.5–6.5
Food applications
Instant preparations: mashed potatoes, soups, cream soups.
Bakery and pastry: improves dough water-holding and texture.
Snacks and extruded products: base for chips, sticks, croquettes.
Meat and frozen foods industry: natural thickener and binder.
Home cooking: quick, versatile thickening and base ingredient.
Nutrition & health
Source of complex carbohydrates with low fat content.
Provides fiber, which supports normal digestive function.
Naturally low in sodium and cholesterol-free.
A practical source of potassium, contributing to electrolyte balance.
Gluten-free, suitable for people with celiac disease.
Portion control is advisable in low-calorie diets due to energy density.
Portion note: a typical prepared serving uses 30–40 g dry granules, yielding ~150–200 g ready-to-eat mash.
Environmental and safety considerations
Generally recognized as safe for human consumption.
Store in a cool, dry place, away from humidity.
Prefer non-GMO supply and sustainably grown potatoes.
Overall low environmental footprint when using efficient drying and valorizing processing by-products.
INCI functions (cosmetic use)
May serve as an absorbent, natural thickener, and texturizer in powders and rinse-off masks.
Mini-glossary
SFA (saturated fatty acids): fats with no double bonds; excessive intake may be associated with cardiovascular risk.
GMO: genetically modified organism.
INCI: International Nomenclature of Cosmetic Ingredients (standardized cosmetic ingredient naming system).
Studies
About 80% of the weight of a fresh potato tuber is water; almost all the remaining dry matter is starch. Most of the starch (70%) is amylopectin, the rest being amylose (1).
Particular warning about the potato skin, which is a concentrate of phenolic compounds with antioxidant activity (2) and dietary fibres.
Potatoes are a source of carbohydrates in the diet all over the world and are generally considered high glycaemic index (3) foods, the parameter that indicates how much glucose is present in the blood.
Another problem with potato consumption is the pesticide residue that can be found in this tuber. Warning should be given as to where it is grown and what fertilisation it is subjected to.
In addition, warning must be given to prolonged frying at high temperatures, which degrades the qualities of the oil and the potato itself, generating acrylamide, a potentially carcinogenic molecule (4)
