Talk:Yeast extract

From Wikipedia, the free encyclopedia

[edit] B12

Yeast extract is not a natural source of vitamin B12 but is recommended as a source of vitamin B12. The primary source of Vitamin B12 are supposedly animal byproducts but the article recommends that vegans consume yeast extract that has been enriched with vitamin B12, although the source for this would be very likely animal byproducts. While this is not logically impossible it doesn't make too much sense to phrase and present it this way. I also doubt the factual accuracy. --Fasten 14:05, 15 December 2005 (UTC)

Red Star brand nutritional yeast with B12 is relied on by vegans, and the B12, as I believe is stated by the company, does not come from an animal source, but from bacteria. Similarly, the Pure Advantage B12 (methylcobalamin) spray is made from bacteria, so the company states. Badagnani 05:42, 22 November 2006 (UTC)

[edit] Hydrolyzed yeast

There's no article for hydrolyzed yeast. What's the difference between hydrolyzed yeast and autolyzed yeast? Badagnani 05:38, 22 November 2006 (UTC)

Autolysis refers to a cell that lyses itself, hence the word auto. Hyrolysis referes to something that was lysed by water, hence the word hydro. Hydrolysis is a process that occurs to many complex molecules, such as sugars, being broken down within the body. Mandalynn 21:13, 26 November 2006 (UTC)

Okay, let's create articles for these things, then. Would you like to participate? I don't know much about the subject but these substances are very widely used as food ingredients and I believe deserve articles. The article at torula, for example, remains a stub (presumably due to nobody being interested to add more) although torula yeast is also used widely in foods. Badagnani 21:16, 26 November 2006 (UTC)

There is an article about hydrolysis already. Hydrolyzed yeast is a moot point. Hydrolysis not necessarily related to autolysis in any way. I think you were just confused by the fact they both have lysis in the word. Lysis is just refering to breaking apart. Mandalynn 21:23, 26 November 2006 (UTC)

Hydrolized yeast is a widely used food additive that is little understood (at least much less than monosodium glutamate, which for which the various yeast extracts are used as substitutes), and thus deserving of coverage at Wikipedia. I don't see that there is any significant discussion of this food additive at the article you directed me to. Thus, I don't agree with you that the detailed coverage of either the food ingredient hydrolyzed yeast or autolyzed yeast at Wikipedia is in any way moot. Thanks anyway.
