How to Extend Your Harvest

If you read my other article on homegrown food preservation, we discussed the advantages and disadvantages of eating food fresh, root-cellaring, and freezing. Even though those are good in many ways, there are disadvantages and many of those disadvantages can be alleviated by using a form of food preservation that can extend the use of our food harvests even longer.

Advantages and Disadvantages of Canning

Processing and sealing food airtight containers is called canning. Canning began after the French military in 1795 offered a cash prize of 12,000 francs for a new food preservation method. By 1806, Nicolas Appert had a proven method of packaging that prevented microorganisms contaminating from the food he canned. Since then, cans and jars have been used both commercially and in homes to can large quantities of all types of foods.

Advantages

Canning alters food chemically by changing the moisture, pH, or salinity levels to protect against microbes, bacteria, mold, and yeast. It also limits food enzyme activity. Combining these chemical processes with the physical barriers of glass jars, seals, and lids effectively prevents decay.

Can keep canned foods on shelves from 1-2 years or longer

Can be economical when using homegrown or locally grown produce.

Disadvantages

Glass jars can break

Seals can be broken causing spoilage

Canning is time-consuming.

Improper methods can be dangerous. When jars fail to seal, spoilage will occur However, inadequate processing or poor sanitation can result in deadly Clostridium botulinum contamination. Strictly following instructions provided with your canner is always recommended.

Most canning is done in the heat of summer and can increase air conditioning costs

Canned food does not taste as good as fresh food does.

Food when canned has lower nutritional value than fresh food does. Canned fruits and vegetables have 65% fewer vitamins and minerals than freshly picked ripe fruits and vegetables do.
