But how long can vacuum sealed food last in the fridge before going bad? That’s the question we’ll be addressing in this piece.
In today’s fast-paced world, food waste is a significant problem. According to studies, as much as a third of the world’s food supply goes to waste. Vacuum sealing is a great way to prevent this waste by extending the shelf life of food, helping you to save both time and money. So, let’s dive in and explore just how long different types of vacuum sealed food can last in the fridge!
Factors that affect the shelf life of vacuum sealed food
Vacuum sealing is a popular method used to preserve food, especially for those who want to keep their food fresh for an extended period. While it is an effective method, the shelf life of vacuum sealed food can vary due to various factors. In this article, we will discuss the factors that affect the shelf life of vacuum sealed food.
- Types of food – Different types of food have different shelf lives. Some food items, like meats and dairy products, tend to spoil faster than fruits and vegetables. The type of food that is vacuum sealed plays a vital role in determining its shelf life.
- Treatment before vacuum sealing – Proper food treatment before vacuum sealing is crucial in determining the shelf life of vacuum sealed food. Preparing food by cleaning it well and removing bruises or other imperfections can increase its shelf life.
- Storage temperature – The temperature at which vacuum sealed food is stored plays a significant role in its shelf life. Food stored at temperatures above 40°F (4°C) can spoil faster than food stored at lower temperatures. It is crucial to store vacuum-sealed food at a temperature below 40°F (4°C).
The effect of oxygen and moisture on vacuum sealed food
Oxygen and moisture are two of the most significant factors that affect the shelf life of vacuum sealed food. Even after vacuum sealing, some oxygen and moisture may remain in the package. Oxygen, in particular, can cause oxidation of the food, leading to a shorter shelf life.
A study conducted by the University of California found that vacuum sealed food stored in a refrigerator had an extended shelf life. After vacuum sealing, the shelf life of food increased by two to three times. However, the shelf life of food decreased when it was exposed to oxygen and moisture. This can be due to the growth of aerobic bacteria that thrive in oxygen-rich environments.
| Factors | Effect on Vacuum Sealed Food |
|---|---|
| Oxygen | Causes oxidation, leading to a shorter shelf life |
| Moisture | Increases the risk of bacterial growth and spoilage |
It is crucial to minimize the presence of oxygen and moisture when vacuum sealing food to increase its shelf life. Some vacuum sealers come with oxygen absorbers and desiccants that help remove these elements from the package.
The difference in shelf life between cooked and raw vacuum sealed food
When it comes to vacuum-sealed food, there is a significant difference in shelf life between cooked and raw foods. While vacuum-sealed raw food can last up to 2-3 years if stored correctly, vacuum-sealed cooked food can only last up to 2 weeks in the fridge.
- Raw vacuum-sealed food can last up to 2-3 years because the removal of air from the packaging helps to prevent the growth of bacteria, which causes food spoilage. This technique is often used in meat and fish preservation as it helps to retain the quality of the food.
- On the other hand, cooked vacuum-sealed food has a much shorter shelf life as the cooking process alters the food’s composition, making it more prone to the growth of bacteria. When vacuum-sealed, the bacteria still have the potential to multiply, which significantly reduces the shelf life of cooked food. This is why it is essential to refrigerate cooked vacuum-sealed food and consume it as soon as possible.
- Overall, both cooked and raw vacuum-sealed food offer significant benefits in terms of shelf life extension and food preservation. However, it is essential to recognize the differences in preservation methods between the two and understand their respective limitations.
If you’re considering vacuum-sealing your food, it is essential to understand the different types of food and their optimal shelf life to maximize their freshness and longevity.
