冷冻保存时间计算器 — 公式
## How to Estimate Freezer Storage Time
### Formula
**Storage Months = Base Time x Packaging Factor x Temperature Factor**
Frozen food remains safe indefinitely at 0°F, but quality declines over time. Freezer burn (dehydration), texture changes, and flavor loss increase with storage duration.
### Base Times (Standard Packaging at 0°F)
- Whole beef/pork cuts: 12 months
- Ground meat: 4 months
- Poultry: 6 months
- Fish: 3 months
- Cooked meals: 3 months
- Blanched vegetables: 12 months
### Packaging Impact
Vacuum sealing removes air and dramatically reduces freezer burn, extending quality life by 50% or more.

计算示例
Vacuum-sealed chicken pieces in a standard 0°F freezer.
- Base time for poultry = 6 months
- Packaging factor (vacuum sealed) = 1.5
- Temperature factor = 1
- Recommended = 6 x 1.5 x 1 = 9 months
- Maximum quality = 9 x 1.5 = 13.5 months
