... one of the other less savoury experiments involved the presenter making a cake from substances in his body which work as additives - lysosyme from his tears, propionic acid from his sweat, l-cysteine from his hair, hydrochloric acid from the digestive acid of his stomach and glycerol from his fat

... propionic acid bacteria are commonly used in the production of alpine cheeses like emmental and maasdam, which collectively account for 7 per cent of global cheese production according to chr ... propionic function by means of lactate fermentation, the bacteria generate propionic and acetic acid during cheese fermentation ... hansen already has propionic cultures in its portfolio that perform this task in alpine cheese

... wageningen, the netherlands—short-chain fatty acids, in particular propionic acid, benefit weight management because they produce the satiety hormone, leptin, and reduce the production of resistin, which improves the effectiveness of insulin, according to new research published in the european journal of clinical investigation ... in the process they produce short-chain fatty acids—acetic acid, propionic acid and butyric acid—that are absorbed by the body and act as an energy source for a variety of organs, such as the gut wall, liver and muscle tissue ... after fat tissue has been exposed to propionic acid it increases the production of the satiety hormone leptin and reduces the production of resistin ... the influence of propionic acid on the production of these two hormones has a two-way effect on the health status of individuals who are overweight or obese—a reduction in food intake and increased insulin sensitivity

... basf is bringing in another price increase for propionic acid, a food preservative, because increasing costs of raw materials mean the margins are unsatisfactory ... propionic acid is a carboxylic acid used in the preservation of food and feedgrain, thanks to its anti-mould and anti-bacterial activity ... the main raw materials of propionic acid are ethylene and naphtha ... basf produces propionic acid at its verbund sites in ludwigshafen, germany, and in nanjing, china ... the representative said the company does not communicate on production volumes, or how much of the acid is destined for use as a food preservative

... researchers also noted if blueberries are eaten together with probiotics, the content of butyric acid and propionic acid increased in the blood, two substances that are formed when fiber are broken down and that have previously been known to be important energy sources for intestinal cells ... they also found that rye bran was broken down in the large intestine, in the same place that ulcerative colitis and large-intestine cancer often occur, and that the rye bran provided a rich supply of butyric acid and propionic acid

... propionic acid occurs naturally in apples, strawberries, grains and cheese ... benzoates, another weak antimicrobial, fight fungi, working best in areas at a low acid level, where there are few bacteria ... acids such as ascorbic acid (vitamin c) and citric acid retard this process by making the ph level uncomfortably low for the enzyme
