Study Notes

Food Preservation

Food preservation is the process of treating and handling food to stop or slow down spoilage, loss of quality, and contamination.
The main purpose of food preservation is to ensure that food remains safe and nutritious for consumption.

Advantages of Food Preservation

Food preservation has several advantages, including:
- Increased shelf life
- Reduced foodborne illnesses
- Improved food safety
- Reduced food waste
- Availability of seasonal foods throughout the year
- Increased convenience for consumers

Significance of Food Preservation

Food preservation is significant because it allows for the availability of food throughout the year, even when it's not in season.
It also helps to reduce food waste and ensures that food remains safe and nutritious for consumption.

Level of Quality

Level of quality refers to the degree of excellence or perfection of a product, which includes attributes such as texture, flavor, aroma, and appearance.

Attributes of Food Quality

The first attribute to be considered in all cases is safety, which refers to the absence of contaminants and toxins that can cause harm to consumers.
Other attributes of food quality include:
- Texture
- Flavor
- Aroma
- Appearance
- Nutritional value

Best Before Date
