Roast potatoes ‘a potential cancer risk’

Acrylamide is found mainly in plant foods, such as potato products

Potatoes  and Acrylamide

Acrylamide is a chemical used primarily as a building block in making polyacrylamide and acrylamide copolymers. They have proven without doubt to be causing cancer in animal models. Scientist believe that the case is not going to be different in humans. The evidence from human studies is not complete.

Researchers in Europe and the United States have found acrylamide in certain foods that were heated to a temperature above 120 degrees Celsius, but not in foods prepared below this temperature . Potato chips and French fries were found to contain higher levels of acrylamide compared with other foods.

Ice Cream and Science

Good quality ice creams contain more fat and less infused air, making for a denser, richer ice cream

 

Everyone loves to eat ice cream. Its smooth texture, sweet taste and rich flavor makes it a perfect dessert.

Did you know that chemistry plays a great deal in making the ice cream perfect ?

Know the science of making ice cream to make the perfect one

Why ice cream floats in an ice cream soda ?

Ice cream has a lot of fat which floats, ice crystals float, and a lot of air which definitely floats. Those ingredients help make ice cream a great floater!

If you refreeze melted ice cream, why is it never as good as it was before?

When the ice cream melts, the liquid ice cream fills up the air pockets. When it refreezes, there are fewer air pockets, so the ice cream is less airy and fluffy. The other reason is that when the ice cream melts, the original tiny ice crystals melt. Refreezing the ice cream makes larger ice crystals which makes the ice cream too crunchy.

Why ice cream tastes overly sweet at room temperature ?

Cold tends to numb the taste buds, because of which they become less sensitive. So more sugar needs to be added to produce the desired effect at the low temperatures in which ice cream is usually served. Hence when you taste ice cream at room temperature it will taste overly sweet.

Why we get head ache while eating ice cream?

It is a kind of short-term headache typically linked to the rapid consumption of ice-cream, ice pops, or very cold drinks. It is also known as Brain freeze. Sensation of brain freeze is caused by a dramatic and sudden increase in blood flow through the brain’s anterior cerebral artery. As soon as the artery comes to normal, the brain-freeze pain sensation goes off.

Food we eat can contribute towards Climate Change

carbon ‘Foodprint’

Food’s carbon footprint, or Foodprint, is the greenhouse gas emissions produced by growing, rearing, farming, processing, transporting, storing, cooking and disposing of the food you eat. How the food is grown or raised and how the food is cooked –both contribute to the carbon footprint.

How Carbon emission is mapped to food?

To understand how carbon emissions is linked to food production, we have to look into all those processes that help in bringing  food from the field to our plates:

Science of Making Yummy Curd or Yogurt

Make tasty and yummy Curd with science

Milk gets converted to tasty and yummy Curd. The credit goes to Protein Casein and Bacteria (mostly). Let’s explore the curd making process in depth. At the end of this, I am sure you will find your learning’s helping you in making better curd.

Little Chemistry:

In a glass of milk, complexes of casein proteins in the form of micelles  floats around. These complexes have negative charge, so they repel each other. When we add to it curd inoculum you are introducing loads of Lactobacillus strain of Bacteria which will make milk acidic.  This causes the casein complexes to change shape and also alter their charge. As a result, instead of repelling each other, the casein complexes coagulate, or come together. As they coagulate, they capture fat and lactose along the way and get combined into a larger and larger solid, which we see as curd.

Cupcake Soap: Have you heard of it ?

The finished product resembles an edible cupcake

Making cupcake soap is part chemistry, part artistry

The image shown here should not be mistaken for cup cakes, these are ‘Soap cupcakes’. They are the best example of creative soap making. The finished results resembles an edible cup cake. For that matter the equipment and tools involved are also borrowed from there. You need Silicone ‘Cupcake’ moulds, Silicone or Plastic moulds for decorations, Hand sprayer, Measuring spoons,  Electric Whisk, Piping bag & nozzle.

Know your Dog better with Science

Know your dog better with science

 

Dogs are man’s best friend. They have not become our close friend by accident, but science has a lot to tell on why we love them and why they love us back. If you are a person who has dog as pet you would be aware of many of its behavioral patterns like, what they want to convey by wagging their tail or going round and round before sleeping.

But did you know that most of these behaviors are not just instinctive or related to only your dog, but science have explained it through experiments the reason behind their behavior.

Dosa, Idli and Science

L. mesenteroides is the microorganism essential for leavening of the batter and, along with S. faecalis is also responsible for acid production

Dosa and Idli – Two common breakfast or snack options. Though it originated in south India, now you can find these two even in US and European restaurants. Chefs have been continuously reinventing these two by adding new flavors and altering the ingredients. At restaurants we get Plain dosa to Chicken tikka masala dosa.

Have you ever thought on how the batter of idli, dosa gets fermented as you are not adding any inoculate or microbe culture as in making curd or baking bread. All credit goes to microbes L. mesenteroides and S. faecalis.

Pigeons are not that dumb !

Pigeons can read

Study suggests that pigeons can recognize words. Pigeons also known as “rats with wings” just might be literate.

“Although their brains are only the size of a thimble, pigeons apparently have similar levels of intelligence as those found in toddlers. Earlier studies have shown they can tell the difference between live video images of themselves and previously recorded images. This ability is higher than the average human three-year-old.”
