Lactic Acid Food Grade 200L -PURAC FCC 80 (LACTIC ACID)   Lactic Acid Food Grade is an organic acid. It has the molecular formula CH3CHOOH. In its solid state, it is white and miscible with water. When it is in its dissolved state, it forms a colourless solution. Naturally, lactic acid occurs as a chemical byproduct of anaerobic respiration in humans, this is the process by which cells produce energy without oxygen. It is also produced by bacteria in yoghurts and is also found in blood, where it is deposited by muscle and red blood cells. Industrially, it is produced by the bacterial fermentation of carbohydrates; fermented milk products are obtained industrially by fermentation of milk or whey by Lactobacillus bacteria. There is another method of production, through the chemical synthesis from acetaldehyde. This is done by reacting acetaldehyde with hydrogen cyanide and hydrolysing the resultant lactonitrile. It can be used in pharmaceutical products because it produces water-soluble lactates from otherwise insoluble ingredients. In the food industry, it is found primarily in sour milk products, these include kumis, laban, yogurt, kefir, and some cottage cheeses. The casein in fermented milk is coagulated (curdled) by lactic acid. Lactic acid is also responsible for the sour flavour of sourdough bread. It is also used in beer making, wine production and as a food additive. To view our full range of food products, click here. Please note this product can only be delivered to commercial addresses.
