Could someone find a figure for the concentration of vitamin C in orange juice? The lemon article gives the concentration in lemon juice as "501.6 milligrams" per liter. --LostLeviathan 01:10, 27 Dec 2004 (UTC)

Also there also seems to be a very small percentile of Alcohol in orange juice due to the yeasting process that can causes beer to have alcohol. The percentage in OJ is so little that it is nearly unnoticable, but it is present.--131.155.99.234 10:24, 27 March 2006 (UTC)

Why is the cloud of particles in orange juice measured in micrometers, versus cubic micrometers? Is orange juice two dimensional? — Preceding unsigned comment added by 174.20.7.227 (talk) 04:29, 5 January 2017 (UTC)

Is there any particular reason why the primary measurement of energy on orange juice kilojoules? Why is it not just the standardly accepted food energy metric Calorie? Manhattia (talk) 17:02, 9 March 2021 (UTC)

External links

The link about industrial orange juice processing in the external links of this article isn't working anymore. I would suggest to change it with a link to a page I've written together with the company I work with, Bertuzzi Food Processing Srl (a company of Mazzoni LB Spa), which is a very well known manufacturer of fruit processing machinery. It features detailed images, videos and diagrams about all the processes and machines used in the industrial production of orange juice, which make it the best resource available on the internet on this subject as far as I know:

Change "Common orange juice is made from the sweet orange," to "Orange juice is defined in the United States Code of Federal Regulations as the "unfermented juice obtained from mature oranges of the species Citrus sinensis or of the citrus hybrid commonly called Ambersweet." cited from https://www.encyclopedia.com/manufacturing/news-wires-white-papers-and-books/orange-juice

Add citations for different cultivars where each property is listed within http://www.oranges.com.au/varieties/ Kzho4403 (talk) 06:39, 20 April 2019 (UTC)

 Not done The FDA's definition is in Orange juice#Regulations in the United States and it is sourced. The wording that you have offered from the encyclopedia does not appear to be correct. Regarding the cultivars, I believe better sourcing is required as oranges.com.au isn't necessarily a reliable source and the cultivars and properties are specific info to Australia.

Orange juice contains synephrine. Why isn't it listed in the section Orange_juice#Molecular_composition ?

Orange juice contains synephrine. I think it should be added in the section Orange_juice#Molecular_composition as follows:

On a molecular level, orange juice is composed of organic acids, sugars, alkaloids and phenolic compounds. The main organic acids found in orange juice are citric, malic, and ascorbic acid. The major sugars found in orange juice are sucrose, glucose, and fructose. The main alkaloids found in orange juice are p-synephrine. There are approximately 13 phenolic compounds in orange juice including hydroxycinnamic acids, flavanones, hydroxybenzoic acids, hesperidin, narirutin, and ferulic acid.[37]

ADDITIONS ARE IN BOLD!

I think it should appear in the section https://en.wikipedia.org/wiki/Orange_juice#Molecular_composition because it is one of the main synephrine sources in a normal human diet.

References

 Not done: Failed verification the study (correct link) is specifically about substances in bitter orange Citrus x aurantium. The oranges used in commercial orange juice according to this article are different varieties or species from the one used in the cited study, including Citrus × sinensis (blood oranges, navel oranges, Valencia oranges, etc.), Citrus × clementina (clementines), and Citrus reticula (tangerines).

The abstract specifically cites:

"...method devoted to the quantitative determination of synephrine in bitter orange samples, containing a high quantity of synephrine, and sweet orange samples, known to contain a low level of synephrine but at the same time being one of the main synephrine sources in a normal human diet. Two bitter orange dry extracts containing 5 and 6% sSynephrine and 10 sweet orange samples have been analyzed."

At the same time this article Synephrine#Natural_occurrences in wikipedia cites:

"However, this compound is found predominantly in a number of Citrus species, including "bitter" and "sweet" orange varieties."

And continues in the In Citrus section (please read the In Citrus section) to claim that p-synephrine is present in sweet orange juice (cited from different sources)

The information given on wikipedia is therefore contradictory.

Either we should add p-synephrine in Orange_juice#Molecular_composition, or the sweet orange juice should be removed from the article about p-synephrine because the two articles Synephrine#Natural_occurrences and Orange_juice#Molecular_composition are not compatible.

Unfortunately, I've Recused from this request for quite some time because I though this was too technical for me. As of right now, this is the oldest SPER, so I'll do it then.

The abstract in the source provided is not the result. It's essentially the background. So I answered your latter request to remove the sweet orange juice seen here. However, I left out anything that was sourced. You can come back and use those sources to support your edit request here. {{replyto}} Can I Log In's (talk) page 05:44, 5 April 2020 (UTC)
