The manufacturing process of IQF (Individual Quick Cold) icy broccoli is as complies with: Resources option:

Thoroughly pick fresh, eco-friendly, firm, pest-free and mechanically harmed broccoli. The size of the broccoli florets is ideally 10-15 cm, and the stems are uniform in thickness to make sure excellent quality, which is the key initial step to make sure the top quality of the ended up item.

Cleaning up and purification: Wash the broccoli thoroughly with lots of running water to remove surface dust, dust, residual chemicals and pollutants. If needed, make use of a mild food-grade cleaning agent to assist in cleaning, and after that rinse with clean water to ensure the tidiness of the broccoli and fulfill food safety criteria.

Cutting: According to the item specifications, cut the broccoli into little florets of suitable size, maintain the florets undamaged, and cut the stems into appropriate lengths. Normally, the stem sectors are 2-3 cm long, which is convenient for subsequent quick freezing and cooking. Consistent reducing dimension can make sure regular fast cold impact.

Blanching (optional): Some manufacturing processes will certainly have a blanching step, where the broccoli is briefly soaked in hot water at 95-100 ℃ for 1-2 minutes. The function is to suspend enzyme task, avoid staining, nutrient loss and high quality degeneration of broccoli throughout storage, and reduce the raw taste, yet the time is precisely controlled to avoid overheating and softening.

Quick freezing procedure: Broccoli swiftly gets in the quick cold tools, such as an efficient fluidized bed quick freezer, and the temperature level is precisely regulated at -30 ℃ to -40 ℃. In this low temperature level setting, the water inside the broccoli promptly forms small ice crystals, which safeguards the cell structure, color, nutrition and preference to the greatest degree. The quick cold time depends on the size of the blossom head and stem, about 8-15 minutes.

Packaging and storage: Pack right away after quick freezing, and utilize moisture-proof and oxygen-proof plastic movie or vacuum packaging bags, which are snugly sealed to isolate air and water vapor. The packaged products are kept in cold storage listed below -18 ℃. The temperature and humidity in the cold storage are stably kept an eye on. The life span can get to 18-24 months, making sure that customers can have accessibility to top quality icy broccoli at any time.
