How to Preserve Food for Future Consumption

Posted by nwnikkie on November 2, 2011

Using Three Simple Old Fashioned Methods

Food Safety Precaution BASICS

1. Wash your hands thoroughly before handling any type of food.

2. Rinse the raw food thoroughly before processing and storing it.

3. Use clean food processing equipment.

4. Always wash the utensils before using them on a different food item to prevent a problem of cross-contamination.

5. Use clean storage containers.

6. Examine the food carefully and discard any food that has mold or bruises or slime or insects or other problems.

7. The shelf life of the food will not be extended forever, but it can be increased by a few weeks to a few months (or longer depending on the food item and the preservation method).

The Three Traditional Food Preservation Methods

These 3 simple ways preserve food using old fashioned techniques do not require the use of any special chemicals, salt or equipment:

1. In the ground.

2. In a root cellar.

3. Drying.


1. In the Ground

(Appropriate for Carrots and Radishes in the Fall)

Leave the vegetables in the original ground where they grew during the summer.

This technique works well with carrots and radishes.

Mulch the ground above the vegetables with a thick layer of straw.

However, if the weather has not yet turned cold and you leave radishes in the ground then they will go to seed.


2. In a Root Cellar

(Appropriate for Some Vegetables and Some Fruits)

A root cellar is a cool dry dark place underground where the temperature remains between 40°F to 60°F (or 4°C to 15°C).

1. The depth of the root cellar below ground will vary between 1 to 3 feet depending on the frost line in the area where you live. The frost line is how deep the ground freezes in winter.

2. Humidity must be controlled.

3. Insects and rodents must be kept out.

A simple root cellar can be made from a clean empty food grade 55 gallon drum. Plant the drum sideways below ground under at least 12 inches of dirt. Put the food in the drum and then attach the drum lid. Shovel some dirt against the lid to keep it cool inside the drum. The drum will stay cool and it will keep out the air and insects and rodents. Do not place the fruit or vegetables directly against the sides of the drum. Instead store the fruit or vegetables inside wood boxes inside the drum.

Apples, peaches, pears, plums, and tomatoes release ethylene gas while in storage and this gas will cause other foods to ripen and spoil more rapidly. Therefore they should be stored by themselves and not with other foods.

Storage Life of Dried Foods

Posted by nwnikkie on June 13, 2011

Introduction

Determining the storage life of foods is at best an inexact science as there are so many variables. These range from the condition your food was in when you first purchased it and includes many other factors. This page was written with input by Mr. Stephen Portela who has over 30 years of professional food storage experience. This information should be used as a general guide only, and should not be followed “as the gospel truth” because your results may be different.

 


Four Factors that affect food storage:

Factor #1: The Temperature:

Temperature has more to do with how long well dried foods store than anything else. The USDA states, “Each 5.6 C. (10.08F) drop in temperature doubles the storage life of the seeds.” Obviously, there is a limit as to how far this statement can be taken. However I expect it basically holds true from room temperature down to freezing. No doubt, the inverse could also be considered true. “Each 5.6C. (10.08F) rise in temperature halves the storage life of seeds.” This theory holds true for non-garden seeds as well.

Storage Life Differences
Depending on Temperature

Constant Storage: Storage life Temp in degrees F In Years —————- ———— 39.76 – - – 40 49.84 – - – 30 59.92 – - – 20 70.00 – - – 10 80.08 – - – 5 90.16 – - – 2.5 100.24 – - 1.25

Note: the above chart is not for a specific food but shows the relationship between temperature and storage life.

 

Let’s look at a couple of real life examples of good and poor food storage practices:
About a year ago we got an unopened paper bag of white flour which had been stored at 70 degrees F, in a dry climate. It had been sitting for 3 years in a closet. It made fine looking bread but had such an ‘old’ and bad flavor that it was difficult to eat. For another example, a couple of years ago in the Puget Sound area we were given a 4 gallon can of wheat that had been stored up high in a garage for about 30 years. This part of the country is not as hot as some places, yet in the summers the average garage still gets up into the 90′s. Even though wheat will store for 30+ years under good conditions, the bread from this particular wheat was very bad tasting and after a few batches we ended up throwing the wheat away (something I always dislike doing).
