Bringing Food Science into Focus
![Page 9: Using Innovation to Keep Foods Fresher for Longer](https://reader035.fdocuments.us/reader035/viewer/2022062500/56815b1f550346895dc8d991/html5/thumbnails/9.jpg)
Sources of Food Spoilage
Physical• Changes in moisture, abuseChemical• Oxidations, browning, proteolysis (light,
heat, enzymes)Microbiological• Putrefication (off-odors)• Fermentation (souring)• Rancidity• Molding
Microbes• Yeasts• Molds• Bacteria• Viruses
Significant food waste occurs due to spoilage, which accelerates with increasing temperature

The Science of Preservation vs Freshness Extension
Freshness Extension
•Refrigeration•Vacuumization•Modified atmosphere•Moisture barrier•Physical protection•Hygienic handling•Minimal processing•Sterilization
Preservation
• Additives• Freezing• Heat treatment/high
pressure/radiation• Drying• Salts and brines• Acid treatments• Smoking• Fermentation

The Role of Materials Science

Packaging is engineered to withstand abuse, provide barrier
and make air-tight seals

Packaging’s Role in Shelf Life Extension
Packaging protect foods from external influences.• Can extend fresh food shelf-life. • Does not change the perishable nature
of food.• Cannot improve food quality if the
product is not of good quality prior to packaging.
