Study Notes
Biotechnological Applications in Food Industry
- The presentation discusses biotechnological applications in the food industry.
- It covers topics such as microorganisms associated with food, fermentation biotechnology, genetically modified food, enzymes in food industry, nanotechnology in the food industry, and ethical aspects of food biotechnology.
- The lecture includes information on the definition, branches, and benefits of food biotechnology, as well as food safety and regulations.
- Different techniques associated with food biotechnology are presented.
Nanotechnology
- Nanotechnology deals with structures from 1 to 100 nanometers.
- A nanometer is 10-9 meters.
- This is a very small scale, far smaller than even most biological structures.
- Nanoscience studies phenomena and manipulation of materials at atomic, molecular, and macromolecular scales.
Nano Food
- "Nanofood" refers to food cultivated, produced, processed, or packaged with nanotechnology techniques.
- Manufactured nanomaterials are sometimes added.
- Examples include nanoparticles of iron, zinc, and nanocapsules containing ingredients.
Why "Nano"
- Particles are small.
- High surface-to-volume ratios.
- React differently, exhibiting new properties.
- Interact differently with light.
- On the scale of small biological structures.
Nanotechnology Applications in Food
- Nano-emulsions: Improve availability and dispersion of nutrients.
- Nano-encapsulation: Enhance nutrient delivery (vitamins, antioxidants, healthy omega oils).
- Edible nano-coatings:
- Enable thin, invisible coatings.
- Can act as a barrier, enhance food preservation, and deliver additional ingredients.
- Used on meats, cheeses, fruit, vegetables, confectionery, bakery, and fast food.
- Nano-packaging:
- Enables smart packaging (capable of repairing holes, responding to environmental conditions, and alerting to contamination).
- Nano-composites: Improved food packaging materials (polymers incorporating nanomaterials to enhance properties like flexibility, durability, and barrier qualities).
- Antimicrobial packaging: Enhance food industry benefits and product shelf life, maintaining food safety by reducing microbial growth.
- Plastic films: Enhance the freshness of food by reducing oxygen and moisture transfer.
- Food storage bins: Kill bacteria stored in (bins with embedded nanoparticles for antimicrobial properties).
- Food processing: Improve bioavailability and delivery of nutrients and other ingredients. Enhanced food processing using nano-encapsulation/nanotechnology for enhanced bioavailability of nutraceuticals.
Branches of Nanotechnology
- Green nanotech: Uses nanotechnology to enhance environmental sustainability in processes.
- Wet nanotechnology: Involves working with large masses of materials created from small components.
- Nanoengineering: Practice of engineering at the nanoscale.
