Methods of Food Processing and Preservation
Food processing methods have many methods and techniques that make foods suitable for consumption. Methods of food processing can be divided into two main categories: physical methods and chemical methods.
Physical methods change a food product’s physical structure or appearance without altering its chemical composition. In contrast, chemical methods create new compounds by adding ingredients to the raw ingredient(s).
Food preservation has been a common practice for centuries, and today, the benefits and feasibility of preservation techniques are recognized worldwide.
The preservation technique can be anything from freezing to drying or using chemicals such as sodium benzoate. There are multiple methods used for preservation which include:
– Freezing
– Canning/bottling
– Smoking/salting
– Fermentation
– Drying/dehydration
Food is placed in vacuum-sealed bags, boxes, or bottles in preservation. These packages are then squeezed out under high temperatures, which kills all the bacteria and other microorganisms that will cause spoilage of the food. Freezing is also a preservation technique used in preservation. This is done by freezing food at certain temperatures, killing all the bacteria. Proper preservation techniques can help prevent food-borne illnesses like botulism and other harmful diseases if food is not preserved correctly.
Food processing is treating food to achieve the goals of safety, preservation, improving flavor or texture, reducing spoilage, eliminating attraction of pests, and increasing convenience. Several different processes can be applied to foods, including pickling, freezing, irradiation, pasteurization, and chilling.
Processed honey has been filtered to remove bee pollen-containing bacteria. Honey has antibacterial properties; however, the filtered
honey will not be preserved as long as non-filtered honey.
Food processing encompasses a wide range of operations, from
milling grain to separating eggs and milk to producing juice drinks. Food processing transforms raw ingredients into food using physical, chemical, or biological processes.
Traditional Method of Food Processing
A traditional food-processing method is a standard way of preserving foods or creating foods intended to be stored for extended periods. Traditional techniques included salting, smoking, and pickling as well as fermentation. These conventional methods have been replaced by industrialized processes in many parts of the world. However, they are still common in some developing countries and rural districts of developed countries.
Different Methods of Food Processing
Food processing is the different methods that are used to process foods. These other methods will help change the food from its natural state into a form that is easier for consumption and storage, such as making it easier to cook or enabling long-term storage of different foods. These different methods include cutting, boiling, baking, frying, and many other different types of processes.
