Study Notes
Food Processing and Preservation Methods and Technologies
Advantages of Food Processing
- Food processing makes food more edible, palatable, and safe to consume and increases the shelf life after harvesting.
Common Food Spoilage Bacteria
- Lactobacillus, yeasts, molds, and other microorganisms are common food spoilage bacteria.
Pickling Methods
- Pickling can be divided into two categories.
- Fermentation, physical, and chemical pickling are types of pickling methods.
- In physical pickling, food is preserved in edible liquids that kill microorganisms and bacteria.
- In fermentation pickling, the bacteria in the liquid produce agents acting as preservatives.
- Pickling methods change the food's flavor, texture, and taste.
Preservation Agents
- Organic acids such as lactic acid and acetic acid are produced during pickling, which act as preservative agents.
- Brine is also used for food preservation, and it inhibits the growth of bacteria along with acids.
Oldest Technology for Food Preservation
- Fermentation is the oldest technology used for food preservation.
Modern Methods of Food Preservation
- Refrigeration and sugaring are modern methods of food preservation.
Other Preservation Methods
- Lyophilization is also known as freeze drying.
- Pascalization is a method that exposes foods to very high pressure to kill microorganisms.
- Nonthermal plasma is a method that exposes the food surface to a flame of ionized gas molecules to kill microbes.
- Modified atmosphere is a method that reduces oxygen and increases carbon dioxide in the storage environment.
Food Processing and Preservation Methods
- Three methods of food processing and preservation are fermentation, physical pickling, and chemical pickling.
- Four appropriate methods for processing and preserving different food commodities are fermentation, pickling, refrigeration, and sugaring.
- Traditional methods of food processing and preservation include fermentation, pickling, and drying, while modern methods include refrigeration, sugaring, and others.
