Food Science Overview

Focuses on understanding various types of food and consumer food choices.
A significant concern is food safety; 90% of people misinterpret food expiration dates.
Consumers often discard food that is still safe or can be consumed after freezing.

Food Deterioration

All foods have a limited shelf life based on several factors like food type and storage conditions.
Shelf life defines how long a food item remains acceptable for consumption.
Many dates displayed on food packaging reflect freshness rather than safety; products past "best, if used by" dates may still be edible.

Food Waste Statistics

Average American discards nearly a pound of food daily, leading to excessive waste.
Common reasons for food waste include picky eaters, overstocked pantries, and forgotten leftovers.
Food waste contributes significantly to landfill volumes, producing methane, a potent greenhouse gas.

Frozen Foods

Freezing effectively halts food aging and prolongs food usability.
Bacteria and pathogens cannot grow at frozen temperatures, preserving food quality.
Items like milk, bread, cheese, and raw eggs can be frozen; eggs should be cracked and beaten prior.

Open vs. Closed Dating

Open dating is common on perishable items (e.g., meat, dairy) and includes phrases like "sell by" or "use by."
Closed dating involves production codes on shelf-stable products; these codes do not reflect consumer-use dates.

Canned Food Guidelines

Most canned goods can be stored for two to five years, while high-acid foods last for up to 18 months.
Signs that indicate potential spoilage include dents and bulges in cans; such products should be discarded.
Nonperishable items like grains and dried goods can remain safe to eat beyond their labeled dates.

Practical Considerations

Nonperishable foods are often usable after their expiration dates, while meat and dairy have shorter shelf lives without federal regulation on expiration dates.
