Week of Taste

How do we taste?
Taste is one of the five basic senses. Flavour is detected by combination of taste and smell. We detect the taste of food through taste cells. Taste buds contain about 100 taste cells and are located in structures on the tongue called papillae. The papillae can be seen on the tongue as pinkish bumps, particularly around the edge of the tongue, and can be more easily seen after drinking milk.
Each taste cell has a taste pore that is capable of detecting several tastes. The five basic tastes are sweet, salty, sour, bitter and umami (meaty, savoury). The taste cell contains receptors which bind chemicals responsible for sweet, bitter and umami. When these chemicals bind to their specific receptors they activate a pathway in the taste cell which sends a signal to the brain, telling us what the food tastes like. Salty and sour tastes are detected differently by the taste cells. Sodium ions in salt enter taste cells through a channel. Acid is mainly responsible for the sour taste and it is the hydrogen ions that trigger the taste cell to send impulses to the brain.


The taste map (or tongue map) which associated each basic taste with a region of the tongue, originated from a German paper in 1901 which was mistranslated into English. The map has since been scientifically disproven. We now know that each basic taste can be detected all over the tongue where there are taste buds.
The brain taste map
For our brain to perceive different tastes the taste cell receptors must send a signal to the primary taste cortex (centre) in the brain. Very recently, scientists mapped the areas in the taste cortex that were activated for each of the five tastes. Each taste signals to it’s own separate area in the brain within a region where all tastes are perceived (the gustatory cortex). Although there is no evidence for a taste map on the tongue, there is now proof a taste map does exist in the brain. This is called the gustotopic map in the brain.


Supertasters
Some people (25% population) are ‘supertasters’ and can detect tastes at a lower level than normal. Scientists have discovered differences in the genes that code for the bitter taste receptor that account for this variation in bitter sensitivity. As a test to study this, scientists use chemicals such as phenylthiocarbamide (PTC) or 6-n-propylthiouracil (PROP) which only supertasters perceive as extremely bitter. Non-supertasters detect a slight bitter taste or no taste at all. Supertasters are more likely to be women than men, and to be of Asian, African or South American descent. Children are more sensitive to bitter tastes than adults, which may explain why they don’t like vegetables such as brussel sprouts and broccoli. It is also thought that supertasters have more papillae than non-supertasters.

Rushing back and forth, carrying four bags at a time, I wanted to put down all the shopping and dig into my not so healthy chicken.

I managed not to starve to death. I got the plates and cutlery and rudely started eating, mot waiting for everyone to come. I ripped open the packaging of the potato salad and the pasta salad.

Not long after I started eating, my family joined me. Half an hour later, all that was left was the grease from the tender barbecue chicken.

What happens when you forget your clothes? I know how it feels, it's absolutely,horrifically,embarrassing but I forgot my clothes for the dance show case last year.I felt like a loner when it was me and Nikki in the car for the food shortly after something happened,the food arrived and I was exited.

100% aussie beef,pickles,ketchup,melted juicy cheese,and all of this was in a soft burger bun (gulping my burger down as fast as I can to talk to Mike and Nikki)3 Doritos later... we were at the juniors and thank god that Ms.Scaysbrook had my clothes for the concert of life!!!

There's a cafe around the corner near my apartment.

This morning I went there for breakfast with my Dad, I ate bacon on toast with mayonnaise. I drank a medium si'zed ice coffee.

I was hungry and I felt saturated when I was finished.

my stomach was stuffed after the delicious taste of fried rice with perfectly cooked shrimp, oysters, and vegetable, Also the freshly cooked beef with salad and chilli. Finally the last dish. It was one of my favorite food, the fried ice cream. The waiter pateintly put it down and walked away.
the ice cream was in a shape of a triangle surrounded by syrup sided with sprinkles and delicious looking stawberrys.
finally I took our spoons and dip it in the ice cream. Then there was a small sound of crack from the crust of the ice cream. so I placed it in my mouth, the ice cream slowly melted on my tongue. the crust started to brake. the amazing taste of sweetness shocked me. It was the best ice cream I tasted.

"Pick the Cassava."My grandma shouts from the other side of the garden,"ok!"I shout back.When we go inside I ask why we picked so much cassava,"it's a surprise."She replies.
Few minutes later.
"What is it?"I ask,"cassava chips."My grandmother replies ,"ewww!" I thought'"cassava, I hate cassava."I reluctantly pick up a chip,I'd said no that would've been rude.I put the chip into my mouth, as i chew on it I expect to spit it out,suprisingly it tasted delicious it had a savoury and spicy taste, in the end when everything was gone I asked for more my grandmother smiled and went back to the kitchen to make more.

My Most Memorable Meal……
Out of nowhere I was presented with an overly filled irresistibly delicious looking lunch box.With everything packed in neatly it was glorious,the colour and have I mentioned “neat”,though I seemed to have noticed something that popped out.In the corner of the plate like box was a piece of yellow an glosy sort of thing.And right away I knew exactly what the amazingly shiny block of food was.As I slowy bit into the side,as I expected the juices of the incredibly sweet corn gushing in my mouth like a heavy but beautiful waterfall.

Once I had finished the delightful part of nature I quickly ate my colourful sandwich.Which was filled with fresh lettuce,nice and cold salami plus smooth melted butter so that I could get onto the healthy fruit salad.Surprisingly we bought it from a very fancy yet cheap coffee restaurant.

But a light switch later it was all over,my adventure through my lunch box was over i felt a pinch of downheartedness.Afterwards I had a bit of a think and realised that I could always finish it later and that meant another exciting journey through my “plate”.So that's what I did.

I'm going to a new restaurant, I had a good meal. It's a little expencive but I enjoy it. I ate some salty and spicy soup. It is a choice foods, me and my mom pick the foods. There's a little mushrooms, big mushrooms, baby corns, etc. I love to put some tofus and I put some mane noodles, I put it in a different kind of soup. I'm the only one that love the original soup, my mom, my dad, and my brother really love Tom yum.

"Saniya do you want to come with me to the market"? Dad said. "yeah sure why not" I replied .Then we hopped in the car and we arrived after that .When we went into the store my dad surprised me with a big smell octopus, it was gross I nearly puked.At first I thought he wasn't going to buy it then he did.

As soon as we got home the fish smell spread. Soon my dad put the watery octopus int the hot boiling water.

Then when it was red and purplish he took it out. When he cut off a piece of the tentacle I was filled with disgust.Then I had a big bite, surprisingly it wasn't that bad and then I asked for some more.

My (BORING) taste story. ⤜(ಠᗝಠ)⤏

(∩◕ᗜ◔)⊃━☆゚.* I could not believe what deliciousness I was seeing. My family had ordered my food, so I didn't know what I was eating until now. Infront of me was a Burger. You probably by now think "OH MY THIS IS JUST ONE OF THOSE STUPID MCDONALDS BURGERS OH I HATE DIS STOREH!" If you think that...well you a 9999999 kilometers from right. The burger infront of me was a... CAMEL BURGER! Yep, you heard it (read it?) a Camel burger. When it was served it was Tender, Crunchy, Juicy, and Steaming with lots of chips on the side.

When I let it cool down for 5 minutes, I was ready to eat. As soon as I was about to take my first bite, Everyone else's meal arrived. They all had chicken, meat, and burgers and chips. They all started to tuck into their meal, and I was ready to started drooling. Now I was ready to start eating. As soon as I took my first bite nothing really mattered to me anymore. The only thing I cared about was the taste of the burger. It tasted like Tender meat, and had a soft bun and a very nice tomato ketchup. It was the best meal I ever had.

The most memorable meal I've ever had was dumpling. I made it with my mum in home. Put carrot and pork fillings on the wrappers. Then the two edge to the middle and up. They aren't leak is wrapped. Finally.
Put the package dumplings,steamed is good.
