Science Project:

The Art of Pemmican

3.5 based on 6 ratings
  1. To follow existing preserved food recipes.
  2. To create new preserved food recipes
  3. To suggest a new or improved method of preserving food.

Research Questions:

  • How is food preserved without refrigeration?
  • What are the most commonly used recipes for preserving food?
  • How is food best packaged to preserve freshness without refrigeration?
  • How can current food-preservation methods be improved upon?

Refrigeration is relatively new to us. For thousands of years or more, people have been inventing creative ways of preserving food without the benefit of cooling. Natural food preservatives include vinegar, sugar and salt. Pemmican, a popular recipe among early Native Americans, was made by mixing dried meat, berries and animal fats. In this project we explore the many styles of preserved foods available today.

Materials:

  • Computer with Internet access
  • Color printer
  • Digital camera
  • Typical office/hobby/hardware/craft supplies (paper, poster board, glue, etc.)
  • Store-bought samples of preserved foods (pickles, jerky, jams & jellies, vacuum-
  • packed products, etc.)
  • Preserved food recipes (see links)
  • Recipe ingredients (see links)

All materials can be found in your home, at local stores, or on ebay.
