Bizarre Attractive Force Found In Mayonnaise

[Ivan Seeking]

Scientists at Rice University have discovered that a little-understood tensile force, which was previously thought to be an oddity found only in the types of plastics used to make bulletproof vests, occurs in everyday emulsions like mayonnaise and salad dressing.


First identified about 25 years ago, the phenomenon known as "negative first normal stress difference" refers to an attractive force that is created within fluids under certain conditions. [continued]

I know a little about this, but not from the attractive force sense, though it would explain many things, it might be that this attractive force also helps make blood clots, or cholesterol deposits. This is what I know.

When making salad dressing, if you don't like an oil and vinegar suspension, that you have to shake up all the time to get a good mix of flavor, then you add the fatty protein of nuts to the suspension, or egg yolk for caesar, and at the right ingredient balance, an emulsion occurs that is nice and creamy, and stays that way. However adding too much of anyone of the three main ingredients, acidic water, oil, protein, then the suspension breaks. The ratio of protein to the mix is lower. Our blood is a very thin emulsion, if there is too much fat, then it precipitates out, or is attracted to the electric charge in the walls of the blood vessels, more than it is attracted to stay in suspension. With an excess of hemoglobin, or in states of dehydration, things occur, in this suspension, that have adverse effects in the human body.

So they say that blood is thicker than water, yes, but not as thick as salad dressing, mayonnaise, or Barbeque sauce. I myself am attracted to mayonnaise, but I avoid it, and instead take in Almonds for fat, or at the very worst, olive oil. My family has a penchant for losing fat from that suspension, and clogging up with cholesterol.

This discovery is certainly fascinating and adds to our understanding of the complex nature of everyday substances. The fact that this tensile force is present in something as common as mayonnaise and salad dressing is surprising and gives us a new perspective on these household items. It also highlights the importance of continued research and experimentation in the scientific community, as new findings and discoveries can be made even in seemingly mundane areas.

The identification of this force in emulsions has potential implications for various industries, such as food and cosmetics, where emulsions are commonly used. By understanding and harnessing this attractive force, we may be able to create more stable and efficient emulsions, leading to improved products.

Furthermore, this discovery reminds us that there is still so much to learn about the world around us. Even in seemingly well-studied areas, there may be hidden forces and phenomena waiting to be uncovered. This is a testament to the curiosity and dedication of scientists who continue to push the boundaries of knowledge.

Overall, the discovery of this bizarre attractive force in mayonnaise is a fascinating and important contribution to the scientific community. It not only adds to our understanding of emulsions, but also serves as a reminder of the endless possibilities for discovery and innovation in the world of science.
