Around 30-40% of harvested food produced globally goes to waste. Proper preservation methods can significantly reduce this staggering number. Vacuum sealing is one effective method and offers a simple yet powerful way to extend their shelf life while retaining flavor and nutrients.
Vacuum sealing tomatoes helps in preserving their freshness for an extended period, reducing the likelihood of spoilage. This technique also maintains the vibrant color and firm texture of the tomatoes, making them suitable for various culinary uses even after an extended storage period. In this post, we'll delve into the method's benefits and provide insights into how vacuum sealing can revolutionize your approach to tomato preservation.
Understanding Vacuum Sealing Tomatoes
Vacuum sealing tomatoes offers several benefits. Firstly, it extends the shelf life of tomatoes significantly. When vacuum-sealed, tomatoes can last up to 2-3 times longer than if stored conventionally. /// This means less frequent grocery trips, freeze, and reduced food waste.
Moreover, vacuum sealing helps retain the freshness and flavor of tomatoes for an extended period. The airtight jar seal prevents oxygen from reaching the tomatoes, which slows down the degradation process that affects their taste and texture.
Vacuum sealing is effective in preventing freezer burn on tomatoes when freezing them for later use. Freezer burn occurs when food is exposed to air in cold storage conditions, resulting in dehydration and loss of quality.
Preparing Tomatoes for Vacuum Sealing
There are a few important factors to consider. Look for tomatoes that are firm and ripe, but not overripe. Overripe tomatoes can turn mushy when vacuum sealed, affecting their texture and flavor. Avoid using damaged or bruised tomatoes as they may not hold up well during the vacuum sealing process.
Before vacuum sealing your tomatoes, it's crucial to understand the importance of blanching them first. Blanching is a quick cooking process where the tomatoes are briefly submerged in boiling water and then transferred to an ice bath. This helps in loosening the skin from the flesh, making it easier to peel off.
Proper blanching ensures that the tomato skins separate easily from the flesh, allowing you to remove them effortlessly before vacuum sealing. This step is essential as leaving the skins on can result in an unpleasant texture after vacuum sealing.
To easily peel your blanched tomatoes, try this technique: after blanching and transferring them into an ice bath, use a paring knife to make a small incision at the base of each tomato. Then gently peel back the skin starting from this incision point; if properly blanched, you'll find that most of it peels away effortlessly.
It's important to note that removing tomato skins before vacuum sealing is crucial because these skins can become tough and chewy once sealed under pressure. By peeling them beforehand, you ensure that only tender tomato flesh goes into your storage bags or containers.
Techniques for Freezing Tomatoes
Without Blanching
Some people opt to skip the blanching step. Blanching involves boiling the tomatoes briefly and then submerging them in ice water. By skipping blanching, you might notice a slight impact on the quality of the tomatoes after freezing. The skins may become tough and there could be some loss of flavor.
However, if you prefer not to blanch your tomatoes before vacuum sealing, consider alternatives such as flash freezing or using a different preservation method altogether. Flash freezing involves placing the whole or diced tomatoes on a baking sheet in a single layer and freezing until solid before transferring them to vacuum-seal bags.
Blanched Tomatoes
Blanching offers several benefits. It helps preserve the color and texture of the fruit by deactivating enzymes that can lead to spoilage during storage. Blanching ensures safety by reducing bacteria levels and extends the longevity of your frozen tomatoes.
