Calcium sulfite is the calcium salt of sulfurous acid. Calcium sulfite occurs as a white, unstable powder that reacts with oxygen to form calcium sulfate. In the presence of acids, it originates sulfurous acid, which is a preservative. In addition to its more traditional function as a preservative, calcium sulfite can be used as a…
E285 – Sodium Tetraborate
Sodium tetraborate is a synthetic preservative considered to be quite dangerous, especially used in caviar (sturgeon eggs). At the moment, it is not known exactly the negative side effects it can cause. If taken in particularly high amounts, sodium tetraborate can cause: asthma, destruction of red blood cells, diarrhea, injury to internal organs, kidney damage,…
E224 – Potassium Metabisulfite
Potassium metabisulfite is a potassium salt of sulfurous acid. It occurs, at room temperature, as a white, unstable powder that forms potassium sulfate by reacting with oxygen. In the presence of acids, it forms sulfurous acid. Potassium metabisulfite is mainly used as a preservative, as well as a bleaching and oxidizing agent. It may be…
Linoleic Acid
What is Linoleic Acid Linoleic acid (LA 18:2) is an essential lipid with 18 carbon atoms that, along with gamma-linolenic acid (GLA 18:3), dihomo-gamma-linolenic acid (DGLA 20:3), and arachidonic acid (AA 20:4), forms the omega-6 group of essential fatty acids. Biological Functions Linoleic acid is a key precursor of several endogenous bioregulators: prostaglandins, which play…
E172 Iron Oxide – Iron Hydroxide
E 172 IRON OXIDE AND HYDROXIDE (depending on the color: C.I. 77492- 77491- 77499) Iron oxide and iron hydroxide are variable coloring agents (yellow, red, brown-black) of mineral origin. They may be contained in chewing gum, candy, and confectionery. No adverse side effects are currently known. ADI DOSE: / no data available.
E214 – E219 Parabens
The following preservatives and their salts belong to the PARABENS family, compounds synthetically produced from benzoic acid and used in the cosmetic, pharmaceutical and food industries as antibacterial and antifungal agents. Specifically, these compounds are: E214 ETHYL-PARA-OSSIBENZOATE or ETHYL PARAHYDROSSIBENZOATE → this preservative is derived from E210. It can cause, in predisposed people, allergies, hyperactivity,…
E201 – Sodium Sorbate
Sodium sorbate is the sodium salt of sorbic acid (E200). Being a salt, sodium sorbate is very soluble, and for this reason it is frequently used; its activity is similar to that of sorbic acid, therefore it can be contained in: confectionery, yogurt and other fermented dairy products, fruit salads, cheese, rye bread and other…
Lactic acid in blood
Generalities What is it, but more importantly, why is lactic acid produced by cells? Lactic acid (C3H6O3) is a weak acid that is produced by cells that derive energy through anaerobic glycolysis, i.e. by splitting glucose in the absence of oxygen. To be precise, anaerobic glycolysis is an essential process that precedes the Krebs cycle…
Folic Acid and Anemia
Folic acid is a B-group vitamin essential for red blood cell synthesis; therefore, a dietary deficiency or related digestive-metabolic defect may result in anemia. Folic acid Folic acid, or rather folates, are water-soluble vitamins whose biologically active form is represented by tetrahydrofolic acid (THF). Folic acid is mainly found in offal and in some foods…
Alpha Linolenic Acid
Generalities Alpha linolenic acid is an essential fatty acid, which is also identified by the acronyms ALA, AaL, LNA, or 18:3 (ω3). alpha-linolenic acid-orig.jpegShutterstock Together with eicosapentaenoic acid (EPA, 20:5, ω3) and docosahexaenoic acid (DHA, 22:6, ω3), ALA makes up the omega-3 essential lipid series. In nutrition, the adjective “essential” defines the total inability of…
