Shelf Life of Fresh Food

Extending the shelf life of fresh food has quite been a primary cause for the food industry, especially for raw food supplies.

Not having proper storage and packaging affects the ability of a business to push the limits of their sales while having in mind the possibility of unprofitable product wastage is also another case.

There are some traditional ways of extending the shelf life of food that has been used throughout history, such as smoking, pickling, freezing, and canning. Food manufacturers benefit from these methods to reduce wastage, maintain the products on sale for much longer, and extend product distribution reached. Every method does increase the shelf life of fresh goods exponentially, but with sacrifice. It also eliminated most of the content and even the original form from its raw material look to a finished product.

By this, the market demands more products without preservatives or some additives just to keep their food from deteriorating. Most of the traditional process includes the said cases, while some just basically change the primary flavours onto something less natural.

Vacuum Packing


The method is to seal away a product from most of the air, which then allows the pack to shrink while maintaining the vacuum with the support of plastic materials. The process maintains the natural content of fresh food and even extends its shelf life to almost a month without early deterioration and keeping moisture out of the fresh goods.

Vacuum packing has significantly saved a lot of food businesses by extending the shelf life of their products to a maximum and changing their distribution to further markets, and increasing their storage capacity since shrunk packaging creates more space for storage that will allow more production that means more available stocks for sale.

This kind of machine also comes with an automatic function that can be very flexible in different kinds of fresh food. There are also a variety of machines that are indeed useful for industrial use that allows a batch of products to be vacuum-sealed in one go.

Sous-vide cooking is a method for pre-cooking or simply treating food with partial cooking and marinating to improve the flavour and be vacuum sealed right away before a consumer even receives the fresh goods. This method of packaging and cooking ensures the taste and nutrients of the food are at the highest level while increasing the shelf life in the fridge up to weeks without worrying about freezer burn.
