Mark Iwadare · Answer

Vacuum packing is a preservation method that is commonly used commercially but not as frequently at home. It involves removing all the air from the food being preserved, which extends its shelf life significantly, often up to 24 months when stored in the freezer. While a special machine is typically used for vacuum packing, a simple trick involving a Ziploc bag is submerging it underwater with the bag open to force out any air, then sealing it closed. While it may not yield the same level of air removal as a dedicated vacuum packing machine, it's a straightforward method that anyone can do at home.Dehydration is another effective preservation technique that involves removing moisture from the food, thereby inhibiting the growth of bacteria and prolonging its shelf life. However, one drawback of dehydration is that it alters the texture of the food being preserved.Lastly, pickling with salt or vinegar is a traditional method of preserving food that has been used for centuries. Salting draws out moisture from the food, preventing bacterial growth, while pickling in vinegar or lemon juice, which are high in acidity, also serves as a preservative by creating an environment hostile to bacteria.These preservation methods not only extend the shelf life of foods but also add unique flavors and textures, making them versatile options for home cooks to utilize to preserve their favorite foods.

Burial used to be a common method for preserving food, especially for root vegetables, tubers, and other plant-based items. Nowadays, it's considered ancient, and only a few cultures in the world practice this preservation method.This technique involved placing food underground in cool, dry earth, shielding it from sunlight, moisture, and pests. The natural insulation of the soil helped maintain a consistent temperature, slowing the decay of the food and lengthening its usable life. Although not widely used today, this method demonstrates the ingenuity of early civilizations.When you bury food, it's protected from light and air. The ground should be dry and somewhat salty, and you need to dig deep enough to be below where the ground freezes. It's best to choose a spot that's dry and sheltered. Fruits and root vegetables were often stored this way. For example, certain types of cabbage, like Rio Verde or Danish Ballhead, when buried upside down with their roots exposed, were traditionally stored during autumn in colder regions and could be retrieved any time before spring.

Given my background in food packaging equipment and processing machinery with C-FAB LLC, I've had the opportunity to explore various innovative technologies enhancing food preservation. One lesser-known method that stands out is High-Pressure Processing (HPP). This method involves the application of high pressure (about 600 MPa) to food products, which inactivates pathogens and spoilage organisms while preserving food quality and extending shelf life. What makes HPP particularly beneficial is that it allows for the preservation of foods without the use of high temperatures, retaining the nutritional and sensory properties of food better than traditional thermal methods. This is because the pressure is applied uniformly, which does not cause significant changes to the food's structure. We've implemented HPP for clients seeking to improve the shelf life and quality of juices, seafood, and ready-to-eat meals, and the feedback has been overwhelmingly positive.Case studies from our work at C-FAB have demonstrated not only an extended shelf life for products treated with HPP but also an enhanced safety profile without the need for preservatives. One example is a juice company that saw its products' shelf life increase from a few days to several weeks, significantly reducing waste and improving marketability. This kind of innovation aligns with our mission to provide sustainable solutions for the food industry while maintaining the highest quality standards. As food safety and quality continue to be paramount, technologies like HPP are paving the way for a new era of food preservation.
