Q & A

What is lactose and why is it removed from some food products?

Lactose is a natural sugar found in milk. It is removed from certain food products because many people have lactose intolerance, which is a digestive disorder caused by the inability to digest lactose properly.

What is biotechnology and how does it relate to lactose-free products?

Biotechnology is the use of organisms, parts of organisms, or biological processes for the benefit of mankind. It relates to lactose-free products because advancements in biotechnology have made it possible to produce lactose-free consumables for people with lactose intolerance.

Can you provide an example of biotechnology in food production?

An example of biotechnology in food production is bread making. Yeast, an organism, is added to the dough to release chemicals through fermentation, resulting in the soft and fluffy texture of bread upon baking.

What is the significance of fermentation in biotechnology?

Fermentation is significant in biotechnology as it is a classical biotechnological process that involves the use of organisms to produce desired products, such as food items, medicines, and hybrid crops.

How is wine production related to biotechnology?

Wine production is related to biotechnology through the use of yeast, a microorganism that feeds on the sugars in grape juice, producing alcohol and carbon dioxide as byproducts, thus converting grape juice into wine.

What is the hepatitis B vaccine and how has biotechnology impacted its production?

The hepatitis B vaccine is a preventative measure against hepatitis B virus infection. Biotechnology has allowed for the development of a recombinant hepatitis B vaccine, which is synthetically made using a small part of the pathogenic virus, improving safety and efficiency in production.

How does the recombinant hepatitis B vaccine differ from the traditional version?

The recombinant hepatitis B vaccine differs from the traditional version in that it is synthetically produced using a part of the virus, rather than being derived from the blood of infected humans, reducing the risk of adverse reactions and making production less painful and more efficient.

What is Golden Rice and how is it related to biotechnology?

Golden Rice is a genetically modified variety of rice that is yellowish in color due to the presence of beta-carotene, which is converted into vitamin A in the human body. It is an example of biotechnology as it was developed to address vitamin A deficiency in populations where rice is a staple diet.

Why is beta-carotene important in Golden Rice?

Beta-carotene is important in Golden Rice because it is a precursor to vitamin A, which is essential for good vision and overall health. The inclusion of beta-carotene in rice helps to combat vitamin A deficiency in regions where rice is a primary food source.

What are genetically modified organisms (GMOs) and how do they relate to Golden Rice?

Genetically modified organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques. Golden Rice is an example of a GMO, as it has been modified to include genes that produce beta-carotene, thereby enhancing its nutritional value.

lactose-free

this is a comment tag which has

foundered many food packets these days

lactose as we know is a natural sugar

found in milk but why should we get rid

of lactose that's because many people

have a peculiar intolerance towards this

natural sugar

however lactose free products but not an

option until a few years back it's all

possible now due to the advancements in

the field of biotechnology that useful

products like lactose free consumables

and many more can be produced so what

exactly is biotechnology well it's

defined as the utilization of organisms

or a part of the organism or any

biological process for the benefit of

mankind for example we know how bread is

made the dough is added with the

organisms like yeast which help in

releasing certain chemicals the

reactions ultimately give us the soft

and fluffy loaf on baking here we've

used yeast organism to obtain the

product of our interest

so do we mean that bread making is a

part of biotechnology well kind of

processes like fermentation are

considered as a part of classical

biotechnology as they include the

utilization of organisms thus obtaining

products for human benefit like food

items medicines hybrid crops and so on

are all possible due to biotechnology

does there are numerous applications of

biotechnology now let's have a look at a

few examples to understand how wide the

field is let's also understand how an

organism or a part of it or some

processes can be used to harvest

important products for mankind

let's take examples of white production

hepatitis B vaccine synthesis and Golden

Rice production let's have a look at

each individually

now wine is usually made from the grapes

how can grapes which are fruits get

converted to a beverage like wine well

this is where the micro organism named

yeast comes into play it feeds on the

sugars present in the grape juice and

releases alcohol and carbon dioxide as

byproducts here a complete organism is

used for the processing of grape juice

and to convert it into wine this was the

first part of the definition the second

part of the definition states that a

part of the organism can be used so how

can that be done for this let's have a

look at the application of biotechnology

in the field of medicine well the

emergence of biotechnology has been

nothing less than a boon for the medical

industry everything ranging from

vaccines to gene therapy has raised the

standards of healthy living now let's

take hepatitis B vaccine as an example

this vaccine has a recombinant version

previously hepatitis B vaccine was

developed from the blood of the humans

who were already suffering from

hepatitis B but this was very painful

for the patients as the amount of blood

required for vaccine production was too

high so extracting some particular

amount of blood of the infected person

was very excruciating and as the vaccine

was derived directly from the patient's

body there could be negative reactions

in the receiving candidate with the

development of biotechnology newer

vaccines that are synthetic in nature

started getting produced on the similar

lines the commercially available

hepatitis B vaccine is now being

synthetically made by utilizing a small

part of the pathogenic virus it's also

known as recombinant hepatitis B vaccine

and studies have shown that getting

infected with hepatitis B is nearly

impossible

if a person is injected with recombinant

hepatitis B vaccine isn't this a miracle

it is equivalent this is also known as

the first anti-cancer vaccine and why so

because it's proven that the vaccine

helps in reducing the chances of

developing liver cancer this is one

example of how apart from any organism

can be used for product development

now that we've glanced at the two

examples of application of the

biotechnology let's move ahead to the

third one the last part of the

definition stated the use of a process

let's take the Golden Rice as a third

example is the rice made of gold

no absolutely not then why is it called

Golden Rice well the rice we usually see

is whitish in color

however the golden rice we're talking

about is a modified version which is

yellowish in color hence the name golden

rice but what makes this rice yellowish

and so important it's the presence of

beta-carotene in the rice and what is

that beta-carotene is a red orange

colored pigment which gets converted to

vitamin A in the human body we all know

the importance of this vitamin it is

most essential for the development and

maintenance of good vision the

deficiency of vitamin A causes vision

related issues and malnutrition

any idea why was only rice chosen for

modification that was because the staple

diet for a majority of the population in

the areas affected with vitamin A

deficiency was rice so to minimize the

deficiency this variety of rice was

developed the modification of rice was

done by exploiting a biological process

making it a classic example of

biotechnological achievements this

variety of rice falls under the category

of genetically modified organisms

abbreviated as GMOs and what exactly are

these G
