A Prebiotic Fiber from Jerusalem Artichoke Tubers with Broad Industry Uses
Jerusalem artichoke inulin is a natural polysaccharide extracted from the tubers of the sunroot plant, best known worldwide as a dietary prebiotic fiber used across the food industry to enrich products with soluble fiber and reduce glycemic impact. Beyond nutrition, this raw material has become valuable in skin care formulation, where it belongs to the category of moisturizing actives, thanks to its ability to form a light film on the skin surface that helps retain water while nourishing beneficial skin microbiota and supporting a balanced microbiome.
In creams, serums, lotions and masks, inulin is typically added to the water phase at temperatures not exceeding 40-45 degrees Celsius, since higher heat can partially degrade its functional properties. A recommended usage rate ranges from 1 to 5 percent of the finished formula depending on the desired texture and thickness. At higher concentrations the polysaccharide can slightly thicken a formula, giving it a silky feel that is particularly appreciated in products aimed at dry or dehydrated skin. It pairs well with other hydrating and prebiotic ingredients, such as Pantrofina NMF, which reinforces the skin's natural moisturizing factor, and with plant-derived proteins like Phytoprotein, which further strengthen the lipid barrier.
In the global food sector, Jerusalem artichoke inulin is widely used as a functional ingredient in baked goods, dairy products, protein bars and beverages, serving as a sugar and fat replacer without sacrificing texture, while also delivering prebiotic fiber that supports digestive health. In pharmaceutical and supplement manufacturing this polysaccharide is valued for its role in feeding beneficial gut bacteria, and in household chemical formulations it is occasionally included in mild cleansing blends to soften the overall profile. Within professional and home cosmetic production, inulin combines effectively with plant proteins, including Soy Protein by Natura-Tec, creating a synergy of hydration and structural reinforcement for both hair and skin. The 100 gram package size is well suited for home-based formulation work and trial batches, allowing formulators to test different concentrations without committing to large quantities of raw material.
Jerusalem artichoke inulin should be stored in a dry place away from direct sunlight, in a tightly sealed container, since the polysaccharide is hygroscopic and readily absorbs moisture from the air. Under proper storage conditions it retains its declared properties for an extended period.
Lightweight Hydrating Gel-Cream
Distilled water 65 ml
Jerusalem artichoke inulin 3 g
Vegetable glycerin 4 ml
Soy protein by Natura-Tec 2 g
Xanthan gum 0.5 g
Broad spectrum preservative 1 ml
Warm
the water and glycerin together in a heatproof container to about 40 degrees
Celsius, then sprinkle the inulin in gradually while stirring continuously
until fully dissolved. Sprinkle the xanthan gum over the mixture while whisking
briskly to avoid clumps, then allow the blend to cool to room temperature
before whisking in the soy protein and preservative. Transfer the finished
gel-cream into a clean jar and store in a cool place, applying a thin layer to
cleansed skin as a lightweight daily moisturizer.
