A Quick Guide for Detecting and Avoiding Spoiled Foods
|
view preview
Whether you're a chef, stay-at-home mom, or food euthanasiast, how food is handled and prepared is extremely important to preventing foodborne infections and food intoxications. As evident with how the coronavirus spread over to humans, millions of people suffer the symptoms of foodborne illnesses when an outbreak occurs. According to the CDC, millions of people are infected with foodborne illnesses every year. Most can be prevented by storing and cooking foods at their proper temperatures and preparing them under sanitary conditions. Here's a brief rundown on how to detect and avoid tainted food items. These Foods... | Are Risky When: | Fresh poultry | - stored raw in the refrigerator for longer than 1-2 days, (3-4 days for cooked poultry)

How to make meat in a lab
|
view preview
The biomass pyramid above shows how a large amount of plant matter is eaten by many small animals which are in turn eaten by fewer numbers of large animals. At each step of the biomass pyramid, matter and energy are lost in the form of energy to keep the animal warm and moving, or as faeces and urine. Therefore, the more steps there are in a biomass pyramid, the more loss of matter and energy that occurs. Humans are usually at the top of the Food Chain or biomass pyramid (unless we are eaten by sharks, lions or bears!). Also, there is often a significant loss of matter and energy at each step that can be avoided. Does that mean that we should all become vegetarians? No. However, we can eat more vegetables and less meat. Food security is an im ...

This peanut butter is a health hazard
|
view preview
I was shopping around in Michigan a few weeks ago when I stumbled upon this product proudly made by the Velvet Peanut Butter Company. I was appalled when I read that it's made from Fully Hydrogenated Vegetable Oil, while the trans-fat count is at zero grams - a very misleading claim. This product is literally poisonous for human consumption, yet it is prepared for young children and people of lower socioeconomic status, given its low price tag. Hydrogenated oil is scientifically known to increase LDL 'bad' cholesterol and lower HDL 'good' cholesterol, thereby leading to heart disease and cancer. It should be against the law to feed it to kids. In the United States, labelling a product trans-fat free doesn't necessarily mean it doesn't conta ...

A Big Mac versus molten copper
|
view preview
Here's what happens when you pour 1 984°F/1 085°C molten copper on a Big Mac. This demonstration has nothing to do with the fact that McDonald's uses preservatives in its ingredients. This is simply a demonstration of the Leidenfrost effect - a scientific principle explaining the phenomena that occurs when a liquid comes in near contact with a solid that is significantly hotter than its boiling point; the surface of the liquid comes to a nearly immediate boil, and creates a thin layer of protective steam. It's much the same effect as when one drops water onto a hot pan and the droplet is seen to dance across the surface. In this instance, the inherent moisture in the burger protects it for a few moments before the copper (at nearly 2 000 d ...

Corn is a man-made invention

view preview
Did you know that delicious yellow corn we've all come to love is a human invention. It is a plant that does not exist naturally in the wild, and can only survive if planted and protected by humans. Scientists believe people living in central Mexico developed corn at least 7000 years ago. It was started from a wild grass called teosinte. ...

A Chinese mystery, can you guess what these are?
|
view preview
The photo shown below was taken at a market in Shanghai, China. Can you guess what they are?If you guessed, water caltrop 菱, you're right! Water caltrops ( Trapa natans) are the seeds of a floating annual aquatic plant that's native to warm temperate parts of Eurasia and Africa. The plant grows in slow-moving water up to 5 m deep, and bear an ornately shaped fruit that resembles the head of a bull or the silhouette of a flying bat. Each fruit contains a single very large, starchy seed. T. natans and T. bicornis have been cultivated in China and the Indian subcontinent for at least 3,000 years for the edible seeds that are used in pastries, served steamed or boiled from street vendors, and even as a remedy for inebriation. ...

Is Nutella even healthy?
|
view preview
Imagine blending modified palm oil, skim milk powder, cocoa, hazelnuts, and whole lot of sugar – that's how Nutella is technically made. In fact, Nutella contains 10.4 percent of saturated fat and 58% of processed sugar by weight. A two-tablespoon (37-gram) serving of Nutella contains 200 calories, including 99 calories from 11 grams of fat (3.5 g of which are saturated) and 80 calories from 21 grams of sugar. The spread also contains 15 mg of sodium and 2 g of protein per serving. You're probably thinking, what if I gather up these ingredients and do it myself, will I have homemade chocolate spread? Not quite. Nutella uses modified palm oil rather than regular vegetable oil because it remains solid at room temperature. This modified oil i ...
