Why You Need To Store These 3 Foods In Glass Jars

The food industry has long been making use of glass jars for packaging specific products. Glass packaging has scientifically been proven to be beneficial for food preservation and safety.

Here are a few food items that must always be packaged in glass jars.

Jams & Jellies

Jams and jellies are breakfast staples in the American household. Whether it’s a classic marmalade or a strawberry jam, you’ll see the colorful jars in almost everybody’s refrigerator. Just as iconic is the food itself, so is the glass packaging it comes in.

Jams are hot hot-fill products. What this means is that they’re poured and sealed into their containers when they’re at or above 85 degrees. This temperature is essential for the jam to maintain its consistency, or else it may become moldy and degrade. Therefore, plastic containers are an absolute no-go for these fruity delights as they can’t withstand the high temperature of the jam.

On the other hand, glass jars can perfectly hold the contents without exploding or deteriorating in the process. Moreover, the acidic and corrosive ingredients of the jam don’t react with glass, maintaining both its taste and the container shape.

Pickles

Another food item visibly seen in glass jars are pickles. Manufacturing companies usually follow one of the three major production processes. Some follow the refrigeration technique, where the pickles are placed in the jars and filled with brine. The jar is then simply refrigerated in stores until it’s purchased by customers. Other companies prefer pasteurizing their pickles. Here the jars are filled in the same manner, but are sealed with a vacuum closure.

In the natural fermentation process, sugars are first converted into acids after the pickles and brine are placed together in a vat. The mixture is then transferred to glass jars, and sealed with a non-vacuum closure.

The brine and acids present in the pickle mix contain ions that can readily react with metal or plastic containers. This can result in oxidation or reduction, affecting the taste and also damaging the container. The inertness of glass jars preserves the pickles in the way they’re meant to be stored.

Olive Oil

Cooking oils, especially olive oils, are also popularly stored in glass containers. These are usually available in dark colored glass jars to reduce the chances of exposure to sunlight. However, clear glass jars are also used for olive oil.

The glass containers are usually placed at the back of shelves, or in darker places. This is done to mitigate the chances of light exposure, as olive oil needs less than 54 degrees for a prolonged shelf life. The reflective properties of glass jars and bottles make them suitable to contain olive oil. In fact, many customers tend to transfer the oil sold in large plastic bottles to smaller glass jars after purchase, to make it last longer.
