Study Notes
Non-Perishable Foods
- Examples include canned goods, grains, and dried beans.
- These foods can be stored for long periods due to their low moisture content, making them resistant to spoilage.
Room Temperature Storage
- Certain foods can be safely kept at room temperature for 8-10 days, influenced by weather and humidity.
- Common examples include bread, certain fruits, and snacks like crackers.
Characteristics of Non-Perishable Foods
- Non-perishable foods have low moisture levels, which minimize microbial growth and enzymatic reactions, allowing them to retain quality over extended time frames.
Frozen Foods Longevity
- Ready-to-use frozen foods are preserved through freezing, which halts the growth of bacteria and molds, extending their shelf life.
Expiry Period for Dehydrated Foods
- The primary reason to consume dehydrated foods within their expiry period is to ensure safety and optimal quality, as their nutrient content can diminish over time.
Convenience Foods
- Convenience foods include pre-packaged meals, frozen dinners, and ready-to-eat snacks designed for quick preparation and minimal cooking effort.
Microbial Activity in Foods
- Foods with very low moisture content, such as dried fruits and grains, exhibit hardly any microbial activity, making them shelf-stable.
Cost of Convenience Foods
- Convenience foods typically cost more than homemade options due to packaging, processing, and marketing expenses that are factored into the retail price.
Nutrient Content of Cow's Milk
- Cow's milk is rich in essential nutrients, including calcium, protein, and vitamins, making it beneficial for health.
Convenience Foods Not Mentioned
- Certain foods like fresh produce or homemade dishes are typically excluded from the convenience food category.
Preparation of Perishable Convenience Foods
- Perishable convenience foods are often vacuum-sealed or packaged in airtight containers to prevent spoilage during storage.
Value of Milk as Food
