Biotechnology in Food and Agriculture

Study Notes

Biotechnology

Biotechnology is the application of modern techniques in fields like engineering and medicine to produce valuable products.
It involves using organisms or parts of them to make diverse products, such as drugs, nutritional compounds, environmentally friendly chemicals, and biofuels.

Biotechnology in Food and Agriculture

Biotechnology helps farmers improve the quality of their animals and crops, increasing yields of milk, meat, cereals, fruits, and vegetables.
Genetically modified organisms (GMOs) are used to produce better quality food products, such as featherless chickens, hornless bulls, and cows that can produce human milk.
GMOs can improve the shelf life of fruits and vegetables, making them last longer on shelves.
Biotechnology has developed bio-fortified crops, such as rice, to increase the content of essential nutrients like iron, vitamins, and minerals.
Institutes like PARC and NIAB in Pakistan are working on food crops for better yields.

GMOs

GMOs are used to produce more food and increase yields, such as GMO corn, tomatoes, and rice.
GMOs can grow taller in water, using less water and increasing production.

Biofortification

Biofortification is the process of increasing the density of vitamins and minerals in a crop.
Biofortified crops, such as rice and wheat, can help combat mineral deficiency diseases like anemia.

Fermented Foods

Fermented foods, such as yogurt, cheese, and pickles, are commonly used at home.
Biotechnology can improve fermented foods by removing allergens and making them more nutritious.
Probiotics are made up of good bacteria that live in the gut and help improve health and wellness.
Prebiotics help in the growth of probiotics in the digestive system.

Biotechnology and Food Production

Biotechnology can improve the quality and quantity of food production, making it faster and more economical.
Modern baking processes take advantage of improved cereal grains and specific enzymes from yeast.
GMO yogurt is produced by GM lactic acid bacteria, which are beneficial for digestive health.
GMO cheese is produced by using an enzyme chymosin, which is traditionally obtained from the fourth stomach lining of young calves.

Biotechnology in Medicine

Biotechnology can help solve health issues, such as diabetes, by producing insulin and other hormones.
In 1982, human insulin was produced by inserting a human insulin gene in bacteria, and it is still saving lives today.
Vaccination is considered the most effective method for disease prevention and control, and biotechnology is used to produce vaccines, such as the Hepatitis B and COVID-19 vaccines.

Applications of Biotechnology

Biotechnology can help solve issues related to food, agriculture, medicine, and the environment.
It can improve human health, increase food production, and reduce pollution.
Biotechnology has enabled the production of biofuels, biodegradable plastics, and textile dyes.

Key Points

Biotechnology uses engineered living organisms to produce valuable products.
Genetic engineering has made it possible to modify not only microorganisms but also higher animals and plants.
Biotechnology has enabled scientists to produce disease and drought-resistant plants.
Genetically modified animals are producing more milk and meat.
Less cost and increased shelf life of food materials are ensuring food security to the increasing human population.
Biotechnology has improved health systems, helping fast diagnosis and personal drugs.
Vaccination is helping to eradicate diseases.
Biofuels are helping to control pollution and reduce the effect of global warming.
Biologically produced dyes are replacing toxic synthetic dyes.
