Pasteurization affects the quality of paneer by enhancing the texture and the body, enhancing the flavour, improving the yield and solid recovery and extending the shelf life of paneer. Paneer is a type of cheese that is non-melting and non-ageing. It is produced by curdling milk with a food acid like vinegar and lemon juice. Pasteurization is an integral process that paneer goes through to ensure that harmful microorganisms are killed. Apart from eliminating pathogens, pasteurization affects the quality of paneer, which is elaborated in this blog.
Enhanced texture and body
Pasteurization affects the texture and the body of paneer quality by altering the chemical and physical structure of milk through denaturing whey proteins. The right pasteurization, around 80℃ to 90℃, causes a coprecipitation of whey proteins and casein, forming a firm and spongy texture that maintains its texture during cooking and can be sliced. The heat helps to create the firm texture, whilst overheating it can make the paneer too dry or rubbery.
Safety and extended shelf life
Pasteurization functions as a barrier against pathogens, and hence it determines the shelf life of paneer. Unprocessed, raw milk can carry various bacteria that shorten the shelf life and can be harmful for consumption. The heating process of pasteurization kills the pathogens, hence making it safe for consumption. This process also kills microorganisms that shorten the shelf life of paneer.
Flavour profile
The end result of paneer has a milder flavour. The pasteurization process inactivates the raw milk enzymes, which prevent the development of rancidity, resulting in a cleaner and milder flavour. Unpasteurized milk has a wild flavour because of the enzymes present in the raw milk. The heating treatment also gives paneer a clean white look, resulting in a standardized taste and colour.
Improved yield and solid recovery
Through pasteurization, high yield and solid recovery are achieved. This is done through the denaturisation that takes place during the heating treatment. When the protein binds with the casein during naturisation, the whey proteins are trapped in the curd during acidification, hence improving solid recovery. The heating process results in a dense and complex protein network, which improves the weight or the yield of paneer.
Machines used to achieve artisan paneer quality
Paneer pasteurizing system: The system ensures that the paneer remains pasteurized to prevent bacterial formation.
Paneer press machine: The machine forms the paneer into shape.
Milk coagulation VAT equipment: This machine converts milk from the initial state to a semi-solid state.
Paneer cooling system: The system keeps paneer in a cool state to maintain its quality and to avoid spoilage.
Conclusion
The right pasteurization process ensures that the paneer is safe from pathogens, it has high quality and a standard flavour. Manufacturers should invest in the right manufacturing machines to achieve a standard quality and for scalable production. To get these premium machines, producers can get in touch with NK Dairy Equipments. Mrs. Himpreet Kaur and her team supply and install paneer pasteurizing systems and other dairy systems. Our team ensures to provide guidance for clients to get the required machines for their business.
FAQ’s
- Does pasteurization result in loss of nutrient value in paneer?
Pasteurization does not decrease the overall nutrient value, but rather the process kills pathogens.
- Does pasteurization affect the yield of paneer?
Pasteurization improves the yield of paneer by triggering the denaturation of whey proteins, which causes them to bind with casein and also results in a solid recovery.
