Sterilisation Of Milk
The sterilizing procedure differs based on the PH of the products: Products having a PH lower than 4.6, such as juices, certain vegetables, and so on, have high acidity. Milk, vegetable creams, and other everyday acidity items with a PH greater than 4.6
Salmonella-causing organisms are seldom seen in low-PH goods. Pasteurization at temperatures between 80 and 100 oC for 30 seconds is generally sufficient (this is always relative as it depends on the product and initial contamination). For further information, see pasteurizers. More rigorous sterilization with temperatures exceeding 150 oC is required for high PH items that grow pathogens. Please visit UHT for additional details.
Microorganisms are killed, disabled, or removed during sterilization. The goals of sterilization in the food and beverage industry are to eliminate any microorganisms and lengthen the shelf life of the products, making the distribution process easier.
Sterilization can be accomplished using various methods, including heat, filtration, chemicals, and others. The most common means of sterilization currently are heat technologies. Sterilization equipment and processes differ from one product to the next. The goal is to achieve a degree of sterilization that preserves the bulk of the items’ freshness and organoleptic attributes.
