Pectin HM in gelato
High-methoxyl (HM) pectin is a plant-derived soluble-fiber polysaccharide (galacturonic acid backbone) used in gelato and sorbet as a stabilizer and thickener. It contributes body and creaminess and slows melt without adding sugar, sweetness, or freezing-point depression.

| Parameter | Value |
|---|---|
| Total Solids | 90% |
| Water | 10% |
| Sugars | 0% |

Typical use: 0.2 to 0.5% of the total mix (about 2 to 5 g/kg); some fruit-sorbet blends go up to ~1%.

Use HM pectin as a texturizing stabilizer, especially in fruit sorbets and acidic bases where it thrives (it gels best at pH below ~3.5 with high soluble solids). It binds free water, raises viscosity, improves body and scoopability, and slows meltdown by building a weak three-dimensional network. It adds almost pure 'other solids' (soluble fiber): treat its POD as 0 and PAC as effectively 0, so it does not sweeten the mix or shift the serving temperature the way sugars do. Because it is a high-molecular-weight polysaccharide, tiny doses hydrate into large viscosity gains, so overdosing turns the product gummy or short. Disperse it with sugar before hydrating to avoid lumps.
Origin & background
Pectin was isolated and named by French chemist Henri Braconnot in 1825, from the Greek 'pektikos' (congealed). Commercial fruit pectin, extracted mainly from citrus peel and apple pomace, was industrialized in the early 1900s and is codified today as additive E440 with a JECFA specification of loss on drying not more than 12%.
