How do you like to have curd – straight from the bowl, marinade the raw ingredients of your favorite dish, or formulate some dessert out of it? As a curd lover, you can have various ways to consume it. But, as manufacturers, we have to follow the same practices and protocols of curd manufacturing in our dairy plant. This is to process the best curd for you that tastes the same every time you consume it. 

Manufacturing curd in dairy plants involves a series of steps and best practices to ensure product quality and safety. Here are some key best practices for curd manufacturing in dairy plants.

Sourcing of Quality Milk

The process starts with the procurement of fresh and quality milk from the milk farmers. Proper storage and handling of the raw milk complying with standards is essential in this step.

However, we implement best practices in checking the quality of the milk we receive at our production facilities. Read to know how we check raw milk quality before processing it.

Pasteurization of Procured Milk

We heat the raw milk to around 85-90°C to kill harmful bacteria and pathogens. Pasteurization helps in extending the shelf life of curd.

Cooling of Pasteurized Milk

We cool the pasteurized milk to the desired inoculation temperature (typically 40-45°C) to facilitate the growth of beneficial bacteria.

Inoculation

We add a starter culture containing lactic acid bacteria (Lactobacillus species) to the milk. This culture initiates the fermentation process and gives curd its characteristic tangy flavor and texture.

Incubation

After inoculation, we keep the milk at a temperature of around 40-45°C for a specific period (usually 4-8 hours). This is the industrial standard complying with all regulatory protocols. This step allows the bacteria to ferment the milk sugars into lactic acid. The duration can vary depending on the target curd texture.

Monitoring of Acidification

To ensure proper acidification, we regularly monitor the pH level of the inoculated milk under incubation. The curd is typically ready when the pH reaches a specific target (around 4.4-4.6).

Cutting and Draining

After proper acidification, we cut the curd. We do this to separate the whey from the curd solids. Note that, this process helps in achieving the desired curd texture. This is a very crucial stage in the process of curd manufacturing in a dairy plant because of its importance in determining not only the texture but also the taste of the curd.

Whey Separation

The whey is allowed to drain away from the curd solids. We do this by using gravity, draining tables, or other equipment for whey separation.

Salting

The addition of salt to the curd is done as per the target taste and texture. Salt also acts as a preservative.

Packaging

The curd is packaged in clean, food-grade containers with proper labeling and storage instructions.

Quality Control

We implement rigorous quality control measures in production to check for taste, texture, and microbiological safety. Additionally, our QC team regularly tests samples to maintain consistent product quality.

In addition to the above-mentioned steps, there are certain practices that we implement, not only for curd manufacturing but also for all milk and dairy products. Here are they – 

  • Maintain strict hygiene and sanitation standards in the dairy plant to prevent contamination and ensure product safety. Click to check how we maintain hygiene in our dairy plant.
  • Comply with local and national regulations related to dairy product manufacturing, including food safety and labeling requirements.
  • Store milk and dairy products at the appropriate temperature to maintain freshness and prevent spoilage during distribution.
  • Continuously evaluate and improve the curd manufacturing process based on customer feedback and industry advancements.

These best practices are crucial for producing high-quality curd and dairy or milk products in dairy plants. Additionally, it’s essential to have well-trained staff and robust quality assurance protocols in place to ensure consistency and safety in the production process.
