Talk:Jojoba

JOJOBA-

I am 62 Yo: resident of Tucson, Arizona, for the last teen years; I eat a cup full of JOJOBA, fresh seeds every month. I have never had any problem eating the nuts, or got ill; The JOJOBA, oil is help me to clear my system from THC, (more work need to be done) smoking Marijuana, and pass the drug test. Great nut to rost and add to my "Musle" (Granola) every morning: (10:00AM = Usre: Adam A Karu August/31/2010 ) sefsfeesfse — Preceding unsigned comment added by 188.52.38.221 (talk) 12:30, 22 January 2016 (UTC)

Jojoba as an ingredient in cosmetics and toiletries

To be correct, entries regarding jojoba's specific use in cosmetics and toiletries should be posted on Jojoba oil or Jojoba esters instead of jojoba. Istvan 13:00, 20 April 2006 (UTC)

not really an oil

I remember reading somewhere that Jojoba oil isn't really an oil. Is this true? (Come to think of it, what makes something an oil, is it just something that is "oily", or does it have to do with some narrolwly defined properties or chemical structure?)Brentt 21:09, 19 November 2006 (UTC)

Oil has a pretty good definition. Stan 18:02, 20 November 2006 (UTC)

It's an oil in that sense. When it's described as 'not really an oil', this probably means 'not a triglyceride'. Most oils of plant or animal origin are triglycerides; jojoba oil is a wax ester.27.252.226.243 (talk) 06:01, 13 December 2014 (UTC)

Is Jojoba Edible?

So is any part of the plant at all edible?24.83.178.11 10:40, 16 May 2007 (UTC)BeeCier

Jojoba oil says it's edible but that it can't be digested, and will make humans sick. Badagnani (talk) 02:24, 20 June 2008 (UTC)

Jojoba seeds in the wild are edible and quite delicious. i am the son of Tom S. Janca who began bringing jojoba to commercial interest in the early 1970's in the US and around the world. I know I shipped seed and oil packets around the world as a child. I have actually eaten quite a few Jojoba seeds during harvest and while making oil and never took ill. T. R. Janca

Jojoba oil article

The head of this article should mention the related article about Jojoba_oil, but I don't know how to do that in the proper way. Anyone else? --95.88.31.146 (talk) 13:21, 25 June 2009 (UTC)

done. István (talk) 15:03, 25 June 2009 (UTC)

Spelling

I find the mixture of US and UK spelling conventions somewhat disconcerting, eg centimetres, color. Dawright12 (talk) 18:04, 18 March 2013 (UTC)

Per WP:RETAIN, I've added a US English template to the talk page. The [earliest version of the article], was written in US English ("mosturizer", not "mosturiser"), by an editor residing in the US. I will change the spelling of "metre" to "meter". Plantdrew (talk) 21:09, 3 December 2013 (UTC)

changes suggested

I would like to make some changes in this article. This is part of my agriculural studies in ETH Zürich.Changes will be done in chapter "Cultivation and Uses" and "References":Yield, Production Conditions, technical utilisation and References.

changes suggested

I (student in agricultural sciences at the federal institute of technology zürich, switzerland) would like to make some changes of this article, in particular:

-add a section on the origin of the jojoba plant

-add a section on the composition of jojoba wax

-change the structure of the section "description" by adding two subsections: 1)vegetative characteristics and 2)generative characteristics

Clarification Requested

Jojoba#Contemporary_uses --> Jojoba oil is interesting for the industry because it is odorless and it has a viscosity which is temperature-independent, where as [[1]] mentions; | viscosity || 48 cSt at 99 °C 127 cSt at 37.8 °C.

Any clarifications? 50.89.240.137 (talk) 18:05, 23 June 2016 (UTC)

this is helpful

I did not know this about jojoba. I just thought it was an ordinary househeld item. thank you — Preceding unsigned comment added by 24.237.111.36 (talk) 01:33, 19 September 2019 (UTC)

I would suggest some additions to the cultivation section:

Cultivation

--> belongs to the cultivation section, no changes but additions

Jojoba grows best in young, coarse soils with minimal profile development. These soils, primarily derived from acid igneous materials, are typically found on slopes exceeding 3 up to over 30 percent. On north-facing slopes is the moisture retention often better and can thus be preferred of the jojoba especially for the youth development .

Jojoba can endure extreme temperature, with summer temperatures up to 46 °C. However, they can on the other hand experience leaf damage in cold conditions. The seedlings are more vulnerable, suffering damage or death at temperatures between three to nine degrees below freezing . Factors such as drought, freezing conditions, and biotic pressures can significantly impact seedling survival. Jojoba thrives at various elevations, ranging from sea level to lower mountain slopes. In Arizona's Sonoran Desert, it is commonly found between 600 and 1300 m. This elevation range provides an ideal environment for jojoba, characterized by well-drained, dry slopes or along wadis, where water runoff can support plant growth.

Jojoba is well-suited for areas with low annual precipitation, typically flourishing where it exceeds 355mm annually. But it is possible to grow and survive for jojoba with an precipitation below 100mm. The optimal range for precipitation is between 450 and 500mm, which provides the necessary moisture for growth. But during the seed development a sufficient water availability is necessary.

By selecting appropriate elevations and ensuring proper water management, farmers can establish successful jojoba plantations that yield high-quality oil. As interest in sustainable agriculture grows, jojoba represents a promising crop for arid regions, providing economic benefits while thriving in challenging environments.

Jojoba

Production

The United States is the largest producer of jojoba oil, followed by Mexico. Due to its economic potential, the plant has been cultivated for over 30 years in several countries. Jojoba oil production has increased significantly and is expected to continue growing due to rising demand, particularly in the cosmetics and pharmaceutical industries.

Jojoba has no significance in the global food system, as it is a non-edible plant with no notable nutritional value. Various cultivars such as 'Benzioni' and 'Hazerim' are available, known for their high yields.

Additions to Uses

Jojoba oil is highly valued in the cosmetics industry due to its similarity to human sebum. Consistent use of jojoba oil is thought to help regulate the skin’s oil production. Additionally, it has a longer shelf life than other natural oils, making it a durable ingredient in skincare products.

Medically, jojoba oil can relieve headaches, throat inflammation, and treat wounds. It has anti-inflammatory, antimicrobial, antifungal, and insecticidal properties.

After oil extraction, the leftover jojoba meal can be used as a low-cost livestock feed. Jojoba leaves also contain antioxidant flavonoids, which have been studied for their potential in treating asthma, inflammation, and cancer.

Processing technology

Jojoba oil is traditionally extracted by mechanically pressing the seeds, often with the use of hexane to maximize yield, resulting in a typical oil extraction of 35–43%. Other methods using organic solvents like chloroform or isopropanolcan increase the yield to up to 55%.

A more environmentally friendly, but more expensive, method is supercritical CO2 extraction. This method can be enhanced by adding co-solvents such as ethanol.

Transesterification is used to convert jojoba oil into biodiesel, where the oil reacts with alcohol (e.g., methanol) in the presence of a catalyst (e.g., sodium hydroxide). Both homogeneous and heterogeneous catalysts can be used, as well as enzymatic catalysts, which are more environmentally friendly but costlier.

Additions to Cultivation

Research continues on options to further increase yields. There are already findings on the types of pruning techniques for the bushes, which are expected to make a difference in yields. Ihuerlimann (talk) 10:45, 28 November 2024 (UTC)
