Impact of processing and new technologies on biodeterioration

Processing and new technologies can have both positive and negative impacts on biodeterioration, which is the degradation of materials by microorganisms, fungi, or insects. Here are some examples:

Positive impacts:

  1. Improved preservation: New technologies like refrigeration, freezing, and dehumidification can slow down or stop the growth of microorganisms, reducing biodeterioration.
  2. Antimicrobial packaging: Packaging materials with antimicrobial properties can inhibit the growth of microorganisms, reducing the risk of biodeterioration.
  3. Modified atmosphere packaging: Packaging materials that control the atmosphere around the product, such as nitrogen or carbon dioxide, can prevent the growth of microorganisms.
  4. Heat treatment: Heat treatment can kill microorganisms and insects, reducing biodeterioration.
  5. Biocides and disinfectants: Chemicals like biocides and disinfectants can be used to kill microorganisms and prevent biodeterioration.

Negative impacts:

  1. Increased moisture: New technologies like washing machines and dishwashers can introduce moisture into materials, creating an environment conducive to microbial growth and biodeterioration.
  2. Increased temperature: New technologies like microwave ovens and electric dryers can generate heat, which can accelerate microbial growth and biodeterioration.
  3. New pathways for contamination: New technologies like online shopping and food delivery can introduce new pathways for contamination, such as cross-contamination between products.
  4. Increased use of plastics: The increased use of plastics in packaging and other applications can create new opportunities for microorganisms to grow and biodeteriorate materials.
  5. Emergence of new microorganisms: New technologies can introduce new microorganisms into environments, which can lead to the emergence of new biodeterioration pathways.

Examples of new technologies and their impact on biodeterioration:

  1. 3D printing: The use of 3D printing can create complex geometries that can trap moisture and create an environment conducive to microbial growth and biodeterioration.
  2. Biodegradable plastics: The use of biodegradable plastics can create new pathways for microorganisms to break down materials, potentially leading to biodeterioration.
  3. Smart packaging: The use of smart packaging technologies, such as sensors and RFID tags, can create new opportunities for microorganisms to grow and biodeteriorate materials.
  4. Food processing: New food processing technologies, such as high-pressure processing and ultraviolet light treatment, can create new pathways for microorganisms to grow and biodeteriorate food products.
  5. Biorefineries: The use of biorefineries to produce biofuels and biochemicals can create new opportunities for microorganisms to grow and biodeteriorate materials.

In conclusion, new technologies can have both positive and negative impacts on biodeterioration, and it is essential to consider these impacts when designing and implementing new technologies.
