What is a Pasteurizer?
Pasteurizers, as the name suggests, are machines that perform the pasteurization process. It is possible to pasteurize many products such as milk, cream, fruit juice, rose water, ketchup, mayonnaise, must, beer, wine, and fruit sauce using these machines. This process can be carried out at various capacities ranging from 5 to 50 tons per hour.
What is Pasteurization?
Pasteurization is a heating method performed in the food industry to rid food substances of pathogenic microorganisms. During pasteurization, a nutritious substance containing enzymes and bacteria is subjected to heat treatment from 60°C to 100°C. The death curve of bacteria is proportional to the acidity percentage of the organism and the applied temperature. The enzymes that cause spoilage in some vegetables also break down at high temperatures. Therefore, heat is applied until reaching the temperature at which the spoilage enzyme will disintegrate and the specific bacteria for that food will die or become inactivated. The central temperature of the food is taken as the basis. Products gain durability from one year to one week according to their nutritional strength. It is appropriate to store and sell pasteurized foods under home refrigerator conditions (5-7°C). The shelf life of foods to be consumed longer than fresh is extended by pasteurization. Milk is heated to 63°C, pickles to 82°C, and tomato juice to 94°C to deactivate bacteria. Halfway through the pasteurization time, the substance is generally cooled with water to 40°C; otherwise, there will be losses in color and quality.
Meat and meat juices cannot be pasteurized, and even if they are, the benefits are very short-lived. Milk is at the forefront of foods commonly subjected to this method. In addition, this method is used for drinks like fruit juices, beer, and wine, as well as some solid foods. Heat treatment at degrees of 101 and above also requires pressure application and is called sterilization. It is applied to high-protein foods such as meat, legumes, and foods containing carbohydrates like flour. Our expertly engineered MIT pasteurizers and food equipment perform these processes in the best possible way.
