Popular questions
What is vegetable glycerin?
Vegetable glycerin is glycerol (E422) derived from plant oils (e.g., soybean, palm, coconut); it’s chemically identical to other glycerin and commonly used as a humectant and sweetener.
Is glycerin bad for you?
Generally no—at typical food and cosmetic levels it’s considered safe (FDA GRAS; EFSA found no safety concern at reported uses); large amounts may cause bloating, diarrhea, or thirst.
Is glycerin good for your skin?
Yes—glycerin is a humectant that draws and holds water in the outer skin layers, helping hydration and barrier function; very high, undiluted use can feel sticky or occasionally irritate.
What is glycerin used for?
In foods it works as a humectant, mild sweetener, thickener, and solvent/carrier for flavors and colors to keep products moist and stable; it’s also used in pharmaceuticals and personal care as a moisturizer, solvent, and plasticizer.
What is glycerin made of?
It’s most often produced by hydrolysis, saponification, or transesterification of natural triglycerides from plant or animal fats; it can also be made by microbial fermentation of sugars or synthetically from petrochemical routes.
How to make isomalt?
Industrial production converts sucrose to isomaltulose via an enzyme (sucrose isomerase), then hydrogenates it (typically over Raney nickel) to yield an equimolar mix of 1,6‑GPS and 1,1‑GPM—together called isomalt.
How to use isomalt?
Use it as a bulk sweetener and texturizer in sugar‑free hard candies, lozenges, baked goods, and sugar art; it melts and resists crystallization for casting or pulling. Because it’s ~45–65% as sweet as sugar, it’s often blended with high‑intensity sweeteners, and intake should be moderated to avoid gastrointestinal upset.
What is isomalt made of?
An equimolar mixture of two sugar‑alcohol disaccharides derived from sucrose: 6‑O‑α‑D‑glucopyranosido‑D‑sorbitol (GPS) and 1‑O‑α‑D‑glucopyranosido‑D‑mannitol (GPM). On complete hydrolysis it yields glucose (50%), sorbitol (25%), and mannitol (25%).
What is isomalt sugar?
A sugar alcohol (E953) made from sucrose that provides about 2 kcal/g and 45–65% the sweetness of sugar, with minimal impact on blood glucose and low cariogenicity.
What is isomalt used for?
As a low‑calorie bulk sweetener and stabilizer in sugar‑free hard candies, lozenges, chewing gum, baked goods, coatings, and pharmaceutical tablets; it’s also favored for sugar sculpture due to its resistance to crystallization.
