Study Notes
Food Classification
- Sugar and flour are classified as non-perishable foods.
Food Spoilage
- Foods with higher moisture levels are susceptible to microbial growth.
- Chemical properties of foods, such as pH, water activity, and oxygen levels, determine their susceptibility to spoilage.
Microorganisms
- Bacteria, yeast, and mold are types of microorganisms that typically spoil fresh foods.
Inhibiting Microbial Growth
- Inhibiting factors such as temperature, pH, and water activity can prevent microbial growth in perishable and semi-perishable foods.
Nonperishable Foods
- Canned goods, dried fruits, and cereals are examples of nonperishable foods.
Perishable vs. Nonperishable Foods
- The primary factor that distinguishes perishable and nonperishable foods is their shelf life and susceptibility to spoilage.
Food Characterization
- The following are NOT characteristics used to characterize the chemical properties of foods: texture, color, and aroma.
Spoilage Prevention
- Microbial growth must be inhibited in order to store perishable and semi-perishable foods effectively.
