Popular questions
Is carrageenan bad for you?
For most people, food‑grade carrageenan (E407) is considered safe at typical food levels by regulators like EFSA and the FDA; a small number may experience digestive discomfort. Concerns often stem from studies using degraded carrageenan (poligeenan), which is not used in foods.
Carrageenan what is it?
Carrageenan (E407) is a family of sulfated polysaccharides extracted from red seaweeds, used as a gelling, thickening, and stabilizing agent in foods.
Does carrageenan cause cancer?
There is no convincing evidence that food‑grade carrageenan causes cancer; studies suggesting risks typically used degraded carrageenan (poligeenan), which is not permitted in foods. Authorities such as EFSA and JECFA consider E407 safe at current use levels.
What is carrageenan used for?
It thickens and stabilizes foods, helping suspend particles and improve texture in products like chocolate milk, dairy and plant‑based milks, ice cream, yogurt, desserts, and processed meats.
Is carrageenan bad for dogs?
Food‑grade carrageenan is permitted in pet foods as a stabilizer and is generally regarded as safe at typical levels, though some dogs with sensitive digestion may not tolerate it well. If your dog shows GI upset, choose carrageenan‑free products and consult your veterinarian.
What is glucomannan konjac root?
Glucomannan is a soluble dietary fiber extracted from the konjac plant’s corm (Amorphophallus konjac), used in foods as a thickener, stabilizer, and gelling agent (E425ii).
How is glucomannan konjac made?
Dried konjac corms are milled, the water‑soluble glucomannan is extracted, then purified (typically by filtration and alcohol precipitation) and dried to a fine powder.
How long does konjac root glucomannan stay in your stomach?
It hydrates and slows gastric emptying but generally leaves the stomach in about 2–6 hours, depending on the meal and dose, then moves to the intestines where it’s fermented. Always take it with plenty of water to reduce choking or blockage risk.
How many grams of konjac root glucomannan a day?
Common supplemental intakes are 1–3 g per day (often 1 g three times daily before meals) with plenty of water; EFSA recognizes cholesterol benefits at 4 g/day. Start low to minimize gas or bloating.
How to make konjac noodles with glucomannan powder?
Blend about 10–12 g glucomannan powder into 1 L cold water, then mix in 2–3 g calcium hydroxide (pickling lime) or calcium carbonate; let thicken, extrude or pour into simmering water, and cook 10–15 minutes to set. Rinse well to remove any odor and firm up the texture.
