Popular questions
What is fruit pectin?
Fruit pectin is a plant-derived soluble fiber (a polysaccharide) from fruit cell walls, extracted mainly from citrus peels or apples and used as a natural gelling agent for jams and jellies.
Is pectin bad for you?
No—pectin is generally recognized as safe and is a soluble dietary fiber; in large amounts it may cause gas or bloating and can reduce absorption of some medicines if taken at the same time.
What is pectin made of?
Pectin is a complex carbohydrate polymer rich in galacturonic acid units, extracted from plant cell walls—commercially most often from citrus peels and apple pomace.
Is pectin vegan?
Yes; pectin is plant-derived and considered vegan, as it’s extracted from fruit byproducts.
What is pectin used for?
It’s used as a gelling agent in jams and jellies and as a thickener/stabilizer in desserts, confectionery, fruit preparations, and some juices or milk drinks, and it also contributes dietary fiber.
Calcium salts of fatty acids why insoluble in water?
Their long hydrocarbon chains are strongly hydrophobic, and Ca2+ forms tightly bound, poorly hydrated ion pairs with the carboxylates, leading to crystalline aggregates that water cannot solvate (unlike the more soluble sodium/potassium soaps).
Calcium salts of fatty acids why insoluble in water divalent?
Because Ca2+ is divalent, it can coordinate two carboxylate groups, effectively cross-linking fatty acid anions into poorly hydrated networks that resist dissolution; monovalent cations (Na+, K+) don’t cross-link this way, so their soaps are more water‑soluble.
