Blueberry oat yogurt, as a healthy snack or breakfast choice that combines fruits, grains, and dairy products, integrates multiple stages of food processing in its production process, mainly including the following key steps:

Raw material preparation: • Milk source processing: Firstly, fresh or refrigerated milk needs to be collected and processed to ensure its quality meets food safety standards. This step may include filtering, standardization (adjusting fat content), pasteurization, etc.

• Blueberry processing: Fresh or frozen blueberries need to be cleaned, selected to remove impurities, and some may also need to be crushed into blueberry jam or blueberry granules, depending on the final product form.
Oat processing: Oats need to be baked, cut, or crushed to become ready to eat oatmeal and may be lightly seasoned Mixing ingredients: According to the formula, mix the processed milk, blueberry ingredients, oatmeal, fermentation agents (usually lactic acid bacteria), sweeteners (if needed), stabilizers, thickeners, etc. evenly.
• Fermentation: • Fill the mixed material into a container and then send it into the fermentation chamber to ferment at a suitable temperature (usually 42-45 ° C) for several hours until the desired acidity and texture are achieved Cooling and adding fruit ingredients: After fermentation is completed, the product needs to be cooled to stop the fermentation process and allow the yogurt to solidify. After cooling, according to the product design, blueberry granules, whole blueberries or blueberry sauce, as well as oatmeal can be added, sometimes before or after packaging.
• Packaging: In order to maintain product quality and extend shelf life, cooled blueberry oat yogurt will be automatically filled into pre disinfected packaging, such as plastic cups, bags, or bottles, and sealed.
• Quality inspection and delivery: The packaged products will undergo quality inspection, including appearance, taste, microbiological indicators, etc., to ensure compliance with food safety standards before they can be shipped for sale.

• Cold chain logistics: As yogurt is a perishable food, it needs to be transported and stored in a cold chain throughout the entire process from the factory to the hands of consumers, maintaining low temperatures to ensure product quality.

The use of automation equipment is crucial throughout the entire production process, including automated filling lines CIP (Clean in Place) system, temperature controlled fermentation chamber, rapid cooling equipment, and modern packaging line to ensure efficiency and hygiene standards.
