First, pretreatment
The cucumbers are washed in flowing water and drained. The ends are cut into crushers and broken into 1 to 2 mm pieces. Then put it in hot water of about 80 degrees Celsius for 2 minutes to achieve the purpose of inactivating enzymes, protecting color, softening tissue, and increasing the rate of juice production.
Second, juice, coarse filter
Pre-cooked cucumber pieces were cooled to room temperature and then juiced in a juicer. The squeezed juice is then filtered through a filter equipped with a 100 mesh screen.
Third, clarify
The finely filtered juice was placed in a closed container, and agar or gelatin containing 0.1% by weight of the juice was added and allowed to stand for about 4 hours to further remove impurities, colloidal substances, and other macromolecular polymers. The clarified supernatant was finely filtered through a 200 mesh screen.
Fourth, deployment
After the juice is filtered, add 0.1% CMC-Na to the weight of the juice. Then according to taste requirements, or add appropriate amount of sugar and citric acid to adjust to sweet and sour taste; or add appropriate amount of salt to adjust to saltiness; or without seasoning , Made of original taste.
V. Concentration
The homogenized juice is seasoned in a vacuum concentrator and the vacuum is controlled at a concentration of 0.8 to 1.0 MPa for concentration. Subsequently, the homogenizer was re-introduced, homogenized under a pressure of 6 to 8 MPa to refine the nutrient particles in the juice, and further separated to make the system more stable.
Sixth, sterilization, packaging
Concentrated juices are transiently sterilized by heat exchangers at 90 to 95 degrees Celsius. 30 seconds. Then in a sterile environment, it is put into a sterilized bag while it is hot, and stored at a temperature of 0 to 10 degrees Celsius.
Can be used directly to maintain the integrity of cell morphology Guidelines recommend cell preservation fluids for sample preservation and transport. It can be used for sputum, bronchoscopic alveolar lavage fluid, pleural fluid and other liquid samples.
