Curd and cream cheese production involve milk fermentation using specific bacteria strains.
The basic steps involved in the production of curd and cream cheese:
• Milk collection and standardization: The milk is collected and standardized to ensure that it meets the required fat and protein content for the specific cheese variety.
• Pasteurization: The milk is pasteurized to kill any harmful bacteria and ensure food safety.
• Inoculation: Specific bacterial strains are added to the milk to ferment lactose and produce lactic acid, which causes the milk to curdle.
• Coagulation: The curdling milk forms curds and whey, which are then separated using a cheesecloth or a strainer.
• Salting: The curds are salted to enhance flavor and prevent spoilage.
• Pressing: The curds are pressed to remove excess whey and form a solid cheese block.
Here are some examples of food products that are made from curd and cream cheese:
• Cheesecake: Cheesecake is a dessert made from cream cheese, sugar, eggs, and other ingredients, which is baked on top of a crust made from crushed cookies or graham crackers.
• Cream cheese frosting: Cream cheese frosting is a popular topping for cakes and cupcakes. It is made from cream cheese, butter, powdered sugar, and vanilla extract.
• Cottage cheese: Cottage cheese is made from curd, typically served as a side dish or used as a filling for stuffed vegetables.
• Indian paneer: Paneer is a type of cheese made from curd that is used in many Indian dishes, including palak paneer and paneer tikka.
• Ricotta cheese: Ricotta cheese is a type of cheese made from whey and curd used in many Italian dishes, including lasagna and cannoli.
• Cream cheese spread: Cream cheese spread is a spreadable cheese often used as a dip or spread for bagels, crackers, and sandwiches.
• Cheesy dips and sauces: Curd and cream cheese can also be used to make cheesy dips and sauces, such as queso dip and Alfredo sauce.
The working principle of making curd and cream cheese involves lactic acid fermentation. The basic principle is to introduce specific bacterial strains to milk, which causes lactose (the primary sugar in milk) to be converted into lactic acid. This lactic acid then reacts with the proteins in the milk, causing it to coagulate and form curd.
The bacterial strains used in the fermentation process for curd and cream cheese are typically lactic acid bacteria, such as Lactococcus lactis and Streptococcus thermophilus. These bacteria are added to the milk, and the mixture is kept at a controlled temperature for a specific period of time to allow fermentation to take place.
Once the fermentation process is complete, the curd is separated from the liquid whey, typically by draining through a cheesecloth or strainer. The curd is then salted and pressed to remove any remaining whey and form a solid cheese block.
The curds are further processed for cream cheese by blending them with cream, salt, and other ingredients to create a smooth, creamy texture. The mixture is then packaged and refrigerated for storage.
The global curd and cream cheese market is expected to continue growing in the coming years, driven by factors such as rising consumer demand for healthy and natural foods and the increasing popularity of ethnic cuisines. According to a report by Grand View Research, the global market for cream cheese is expected to reach $5.5 billion by 2025, with a compound annual growth rate (CAGR) of 4.2% from 2018 to 2025. The report also notes that North America is the largest market for cream cheese, with Europe and Asia Pacific following closely behind.
Similarly, the global curd market is also expected to see steady growth in the coming years, driven by growing awareness about curd's health benefits and increasing demand for ethnic cuisines. According to Research and Markets, the global curd market is expected to reach $20.1 billion by 2026, with a CAGR of 4.9% from 2021 to 2026.
