Experiment 14 To detect the presence of starch added as an adulterant to the Milk #biologypractical

The starch is still a child. You will have many, many lives in your life. You must surely be attending the ATJ practical. Because the child is your 11th Your 12th-grade Sadi Press is being made You must surely be keeping a lot of practical things in your life. Subster, I'll tell you I have the app for three different types of protein. A bicycle has an adult tricycle milk in it. And the rebel has two of your piaos. I know this, but you don't know these things. Now, this powder has been properly processed and is pure, so let me inform you that the synthetic milk produced, meaning the milk preparations made at shops and the like, In those shops, they mix starch into the besan, increasing its quantity and making it very cheap and inexpensive. Therefore, here we increase milk production, but the starch that we have is very difficult to decompose for our cattle. Why? Because if you heat starch, it will convert into glucose and sucrose, but if you consume this milk directly, it becomes too much for your stomach, which can be dangerous. And this is our Experiment Number 14, in which we will find out about milk's adulteration. I told you that we have three milk samples here, one of which contains adulteration. The others are pure samples. Let's find out which one is adulterated. To determine this, we need a child, and iodine is required. If starch is present in any milk, the iodine solution will react with the starch and produce a blue color, indicating that our milk is adulterated. We use this test to detect adulteration. And first, I'll introduce the milk sample into this, okay? Now, what should I add here? What did I say? I'm about to add iodine solution here. And if there's starch in this, your child's... You're right, in this case, what will they add? A single drop—just look, you'll see that this first sample of milk hasn't turned blue or black at all. So in the vacuum, this is clearly not a fake. Yours, yours, this one Shampoo's ampi lickingi has no effect at all. And there is starch, isn't there? Does it contain starch or not, and what kind of money do they earn? We collect the second sample we have taken. Alright, now we'll take this one here, the second sample we have. You can take either cow milk or buffalo milk. And in this, we add the iodine solution. And let's see what changes we get to observe in this. Now it's pure, this is also ours, pure milk, not even slightly adulterated Now we test the third sample and check whether it is adulterated or whether it contains starch mix. Alright, this is my third sample, kid, and we're going to test this third sample This is the third sample of milk, and we will add a few drops of iodine solution to it. And if it gets converted into blue or black, what will remain of your starch, will it still be present? It has already been converted to blue is black for you; you can see the changes. You will see the difference here and here — it's a world of difference, like heaven and earth. This one is yours, pure. But just as your blue or black one has a solution, milk's solution appears after adding iodine solution. So definitely in milk, what is there is your adulteration.
