History of Food Preservation
Preserving food is a normal household thing. Almost everyone has a refrigerator in the house to store food and to save it from getting spoiled. The need to preserve food is not new, and it has been there since humans existed. But earlier, the need was less as people never stored food with them, as much as we do today. They used to hunt for the food in the required amount. But slowly, as humans started living in groups and started becoming agrarian, they felt the need of storing and preserving food grains.
With the advent of developing society, new food items and recipes found their place on daily platters. And the food preservation history dates back to this era of ancient civilization. But, the drastic changes and advancement in food preservation started taking place from 18th century. The progress of science in 18th and 19th century heavily influenced the food preservation methods and processes. This article talks about the history of food preservation methods and preservatives that made a permanent mark in the food preservation industry.
History of Food Preservation by Canning
During the 18th century, drying, curing, sugaring, pickling, etc., were some of the most common methods of preserving food, but when the population and food quantity started increasing, people needed something more than natural food preservatives. And this is the time, a not so trained scientist known as Nicolas Appert came up with a new method. He designed a new process to preserve food, which involved cooking the food and then sealing them inside sterile bottles or cans. This process is today known as canning. This process was introduced toAmerica by William Underwood after the civil war was over. Later, in 1858, John L. Mason designed a canning jar with a rubber gasket and metal cap, which were produced on a mass scale.
History of Food Preservation by Pasteurization
The problem of excluding air out of the container was later solved by Louise Pasteur. He studies that particles in the air can also contaminate or spoil the food. After few years of studies and experiments he designed a swan neck flask to exclude air from the preservation containers. Using his unique design, he boiled yeast soups in airless flasks and observed no contaminants. Later on he conducted many experiments with various food products, especially liquids, such as, milk, beer, wine, etc. He discovered that heating foods on high temperature kills microbes and unwanted flavors. This process is today known as pasteurization. This discovery set the road for further research in microbial processes.
History of Food Preservation by Freezing
The process of freezing was discovered by Clarence Birdseye at his home inCanada . He stored some foods in ice and realized that they were fresh and no change in the flavor or quality occurred. Then soon he designed a method for freezing foods. He soaked metal plates in calcium chloride brine and made them cold. The food was stored between these cool plates. It was considered as one of the healthy ways to preserve food. In 1930, the first Birdseye freezer was launched in Massachusetts . He designed various freezers for domestic as well as commercial utilization.
One of the interesting facts about food preservation history is that all the methods have evolved and evaluated with time for food safety and safer food consumption. Based on the old principles, a lot of new preservation and food packaging methods have been designed, such as, vacuum packing, jellying, pulsed electric field processing, and high pressure food preservation. Food preservation methods changed the way people ate and lived. It brought the whole new branch of foods in the food industry and the society at large.
Now you know how glorifying the food preservation history is, that allows us to relish on our favorite delicacies at any given season and time.
