Image ratio unclear

The image linked in the Starter section, namely https://wiki.riteme.site/wiki/File:Sourdough-process.svg is unclear to me.

The Flour 8u/3 and Water 4u/3 on Day 1 is confusing. What is the /3 here? Since 8u and 4u is a ratio, dividing both sides by 3 does not make sense. But then again, that's why it's unclear to me. — Preceding unsigned comment added by Snakiej (talk • contribs) 21:42, 8 October 2023 (UTC)

Health Section

I know it might just add to the frequency of vandalism by errant users if a health section were added to this page but I just thought I'd make that suggestion. Very few studies exist on sourdough and of course sourdough remains outside of the mainstream so more studies are not likely to arise soon, however I have run into a few articles which cite studies that show sourdough to be better for people with gluten sensitivity and some even claim that Celiacs can consume sourdough (not recommended because of the danger). Also, diabetics have been studied and found that sourdough (even white sourdough) has less of a negative impact on diabetic blood sugar levels than both white and whole grain bread made with bakers yeast. seaniz (talk) 11:12, 16 November 2016 (UTC)

You're surely right to be cautious, both for the reasons you mention and for the constraint that medical claims should comply with WP:MEDRS. I think we can add a brief mention of potential benefits, but anything actually medical requires double-blind controlled trial sourcing. Chiswick Chap (talk) 11:27, 16 November 2016 (UTC)

Sourdough inconsistency

Hi Zefr. You have reverted my sourdough edit, saying a PhD thesis as a source is not acceptable. At the same time, you are permitting unreferenced statements in that same paragraph, simply annotating "citation needed" rather than deleting those unreferenced statements. Can you please explain your logic? Genuine question, because your inconsistency is causing me unnecessary work.86.170.121.194 (talk) 22:22, 13 December 2017 (UTC)

On Wikipedia, ideally several editors would reach consensus about the factual quality of the content supported by high-quality secondary references, preferably with peer-assessed published reviews per WP:PSTS. Presently, the subsection is called "Effects", but there is sparse content on actual effects, and the section wanders with details about amounts of fructan present. I'll leave your thesis ref in place while you, I, or someone else finds an accessible review in English. --Zefr (talk) 00:08, 14 December 2017 (UTC)

Thanks for responding, Zefr. I can live with the current compromise (although I still do not understand your logic why you prefer placing a "citation needed" reference rather than deleting an unreferenced statement.)

Next question: the cited rye bread PhD thesis contains a chapter reviewing the literature on fructan content (and on many other bread constituents). No such review exists to my knowledge in English unfortunately, at least not on PubMed or on Google. Therefore I opted for German because the Germans probably have the most refined (excuse the pun) bread-making tradition in the world. Incidentally, this 2007 thesis is NOT about health effects - on the contrary, back in 2007, fructan and other indigestibie fibres were considered a healthy and desirable bread constituent, and the PhD author is worried that sourdough may reduce the fibre content too much. Question: his literature review refers to a couple of potentially interesting German primary sources measuring fructan content not only in rye bread but also in wheat bread. It will take me some work to obtain those obscure German journals. Should I undertake this effort, or are you going to delete any such work I do? 86.170.121.250 (talk) 07:44, 14 December 2017 (UTC)

Opinions on the use of primary sources are not uniform on the English Wikipedia. Much of WP:PSTS is written from a social science and history perspective, not from a physical science perspective. The general view taken by science editors here more-or-less reflects the statement A primary source may only be used on Wikipedia to make straightforward, descriptive statements of facts that can be verified by any educated person with access to the primary source but without further, specialized knowledge, although for many if not most scientific sources, primary, secondary or tertiary, "further, specialized knowledge" is needed, particularly of terminology. Personally I would say that for statements about the chemicals present in a material and their quantities, a primary source is acceptable. Any evaluation of the consequences of these facts needs secondary sources.

PhD theses are problematic for a different reason: only the examiner(s) have reviewed the material, and as a former PhD supervisor, I chose examiners carefully from within a community of shared research interests and goals. Usually there will be one or more journal publications resulting from a PhD thesis, and these make much better sources, since they have been reviewed by anonymous journal reviewers and can be commented on by others in later papers.

There's no problem in using German journals as such, although you need to be careful as to their reputability. The reliability of a journal depends on the quality of its review process. Peter coxhead (talk) 09:18, 14 December 2017 (UTC)

Thanks for your support Peter. I am nevertheless awaiting Zefr's approval before researching or adding further new references, lest he disagrees and deletes my editing efforts. Looks like Zefr is in a transatlantic time zone and therefore I hope he will reply later today. Meanwhile, here is some of the promising primary literature, reviewed and cited in the PhD thesis with regards to fructan breakdown during the bread-making process: 86.170.121.250 (talk) 11:05, 14 December 2017 (UTC)

• Escriva C, Martinez-Anaya MA (2000) Influence of Enzymes on the Evolution of Fructans in Sourdough Wheat Process. European Food Research and Technology. 210 (4), p. 286-292.
• Fretzdorff B, Welge N (2003) Fructan- und Rafffinosegehalte im Vollkorn einiger Getreidearten und Pseudo-Cerealien. Getreide, Mehl und Brot. 57 (1), p. 3-8.
• Fretzdorff B, Welge N (2003) Abbau von getreideeigenen Fructanen während der Herstellung von Roggen-Vollkornbrot. Getreide, Mehl und Brot. 57 (3), p. 147-150.
• Pontis HG (1989) Fructans and Cold Stress. Journal of Plant Physiology. 134 (2), p. 148-150.

My perspective on this section is for the potential gastrointestinal complications from consuming fructans in sourdough bread, implicating the need for WP:MEDRS-quality sources which tend to be more stringent for quality than other disciplines. We should seek references less than 5 years old, according to WP:MEDDATE; the above 4 sources offered are out of date, and hopefully can be substituted with more recent work. I made further article revisions to keep the discussion focused on the potential GI effects of sourdough fructan. --Zefr (talk) 16:25, 14 December 2017 (UTC)

Good evening Zefr. I see where you are coming from (the medical angle). My worry is that Sourdough should not really be a medical article, and the claimed health benefits are in my view not yet reliably researched. But we should mention some of the health claims because they constantly come up in the popular media. How about this solution: we put the fructan/chemical composition of sourdough bread in the previous section "Biology and Chemistry". And then rename the "Fructan" section as "Health Aspects" or similar. And then in the Biology/Chemistry section we can apply relaxed Wikipedia citation rules (allowing us to include the PhD review and those 4 obscure references, once I have chased them up and confirmed they are useful). And in the medical section we mention the potential health consequences of teh chemical composition, and use your stringent Wiki med-source criteria. I am making a start so you get my meaning. Feel free to edit or revert my edits. 86.170.121.250 (talk) 17:26, 14 December 2017 (UTC)

The health section does not explain the context of sourdough

The first 75% of the health section just talks about gluten sensitivity. What that has to do with sourdough bread is not explained. I don't know the answer so I can't fix this. N^oformation ^Talk 21:07, 6 November 2018 (UTC)

Indeed we can't figure out from the text the connection to gluten: does sourdough bread have more gluten, or is it less harmful to those with such a sensitivity. Limit-theorem (talk) 10:15, 11 November 2018 (UTC)

I removed the soapbox excessive discussion of coeliac disease (WP:SOAP), and focused the content more toward the use of sourdough fermentation and lactic acid bacteria as quality factors for bread-making, especially for gluten-free bread. --Zefr (talk) 16:42, 11 November 2018 (UTC)

"Seor" listed at Redirects for discussion

An editor has identified a potential problem with the redirect Seor and has thus listed it for discussion. This discussion will occur at Wikipedia:Redirects for discussion/Log/2022 April 19#Seor until a consensus is reached, and readers of this page are welcome to contribute to the discussion. _signed, Rosguill ^talk 15:21, 19 April 2022 (UTC)

Redirections

Question, is this the same as Rustic bread? If yes, should a redirection be added? Thank you. Zo'Ihana (talk) 08:56, 24 March 2024 (UTC)

Partial revert

Hi Mfoshee2, I have reverted the removal of some links and references in your edit, keeping what I think is good rephrasing for conciseness. With no edit summary I'm not sure why you thought those removals were necessary – they seem helpful enough to me – but I'd be happy to have it explained here. : ) Semlet (talk) 10:07, 7 November 2024 (UTC)
