Sodium alginate is derived frombrown algagenerickelporsea grapeMiddle extractioniodineandmannitolSubsequentby-productIts molecule consists of β -D- mannuronic acid (β -D-mannuronic, m) and α -L- guluronic acid (α -l -L-guluronic, g) press (1→ 4) key connection. The aqueous solution of sodium alginate has high viscosity and has been used as food.Thickener、stabilizing agent、emulgatorWait. Sodium alginate is a non-toxic food, which was included in the United States Pharmacopoeia as early as 1938. Sodium alginate contains a lot of — COO－-,which can show polyanionic behavior in aqueous solution and has certain adhesion, can be used as a drug carrier for treating mucosal tissue. Under acidic conditions, — COO－-into — COOH，ionization degreeWhen decreasing, the hydrophilicity of sodium alginate decreases, the molecular chain shrinks and the pH value increases, — COOH group dissociates constantly, and the hydrophilicity of sodium alginate increases and the molecular chain stretches. Therefore, sodium alginate has obvious pH sensitivity. Sodium alginate can quickly form gel under extremely mild conditions, when Ca2+, Sr2+ and so on are present.cationWhen it exists, Na+ on G units reacts with divalent cations, and G units pile up to form cross-linked network structure, thus forming hydrogel. Sodium alginate formationgelMild conditions, which can avoid sensitive drugs, protein,cellandenzymeInactivation of such active substances. Because of these excellent characteristics, sodium alginate has been widely used in food industry and medicine.

Some time ago, the masses talked about itsodium alginate, or jellyfish silk, or alum will lose color, resulting in many foods containing sodium alginate and alum are afraid to eat. This phenomenon is caused by a report about "10 tons of man-made, jellyfish silk enters the market, sodium alginate and alum seriously exceed the standard, and they are used or become stupid during childbirth". Reported by a big media, it is said that it has occupied the headlines of Baidu. What nutrition does sodium alginate have? Today, Hongjie Algae Xiaobian will explain to you: the nutritional value of sodium alginate.

　　Sodium alginate is marine water-soluble dietary fiber (belonging to the seventh kind of nutrient "dietary fiber"), not ordinary cellulose! Ammonium alginate can be limited to combine with lead, strontium, cadmium and other heavy metals in the intestine to form insoluble substances, so that these heavy metals are not absorbed and eliminated from the body, which has the health care function of promoting the discharge of heavy metals; However, the complex (chelate) formed by sodium alginate and magnesium, iron, zinc, etc. has a weak binding force, and they play a balancing role on these metal ions (it is considered that free iron and other metal ions in the intestine are too much), and magnesium alginate is a complete aqueous solution, so iron, magnesium and zinc are not bound and can still be absorbed by the human body; On the whole, sodium alginate is beneficial to clearing intestines and discharging heavy metals, and it is a health care factor.
