Preparation and Safety Guidelines

Tools Needed
  • FoodSaver vacuum sealer
  • Half-gallon canning jars
  • Wide-mouth jar lids and rings
  • Pint canning jars
  • Coffee filters (or paper towels)
  • Paper towels (damp and dry)
Safety Guidelines
  • Always ensure your food is completely cooled before vacuum sealing. Hot food will create steam inside the bag, potentially causing it to burst or compromise the seal.
  • Inspect bags for any punctures or damage before sealing and using. Damaged bags can leak air and reduce the effectiveness of vacuum sealing.
  • Understand the limitations of vacuum sealing. While it extends shelf life significantly, it does not eliminate the need for proper food safety practices. Check for spoilage before consuming, regardless of the sealed date.

Step-by-Step Instructions

  1. Prepare Jars and Ingredients

    • Choose your desired size canning jar (half-gallon, quart, or pint). Ensure the jars are clean and dry.
    • Fill the jar with your chosen baking supply (cocoa, flour, sugar, coconut, chocolate chips, etc.). For powders, a paper towel filter can prevent clogging the vacuum sealer.
    • If using fine powders, create a circle from a paper towel and place it inside the jar, under the lid, to prevent clogging the vacuum sealer.

Tips

  • Buy canning jars in advance, especially during the off-season.
  • Stock up on sale items and vacuum seal them to extend their shelf life.
  • Use wide-mouth jars for vacuum sealing and regular mouth jars for canning to save money on lids.
  • Use coffee filters or paper towels as filters for fine powders to prevent clogging the vacuum sealer.
  • Always wipe the jar rim with a damp paper towel before sealing to ensure a good seal, especially with powders.

Common Mistakes to Avoid

1. Not Removing Excess Air

Reason: Leaving air pockets in the bag allows for oxidation and spoilage, negating the benefits of vacuum sealing.
Solution: Ensure the bag is completely flat and use the vacuum sealer's function until all air is removed.

2. Using Damaged Bags

Reason: Tears or punctures in the bag will compromise the seal and allow air to enter, leading to spoilage.
Solution: Inspect bags for damage before sealing and replace any that are compromised.

3. Improperly Storing Sealed Items

Reason: Exposure to heat, light, and humidity can degrade the quality of sealed goods, even with a proper seal.
Solution: Store vacuum-sealed baking supplies in a cool, dark, and dry place.

FAQs

Can I vacuum seal all baking ingredients?
While most dry baking ingredients are suitable for vacuum sealing (flour, sugar, spices, etc.), some items like fresh yeast or delicate nuts might not benefit as much or could even be damaged by the process. Always check for any potential negative effects before sealing delicate items.
