Frozen Diced Celery

Basic material option and pretreatment
Resources option Select fresh, crisp, free of parasites and conditions, and without yellow and rotten leaves. There are numerous selections of celery, such as western celery and celery, which can be used to create icy diced celery. Western celery has large and thick stems and crisp structure, while celery has a solid scent. Select the best selection according to product positioning and market demand. Typically, the size of celery is called for to be regarding 30-50 centimeters, and the size of the stem is between 1-3 centimeters. Cleaning Wash the celery with a huge amount of running water to eliminate the dust, pollutants, chemical deposits, etc externally. You can use a combination of saturating and spraying.

First, saturate the celery in tidy water for 10-15 minutes to totally saturate and loosen up impurities such as dust, and then wash it extensively with a high-pressure spray gadget. Pay unique focus to cleaning up the creases of the celery stems and the spaces between the leaves to make sure that they are clean. Cut and eliminate leaves (optional). Decide whether to keep the celery leaves according to item requirements. If only the celery stems are required, the fallen leaves can be eliminated. After eliminating the leaves, reduced the celery stalks into suitable lengths, normally about 20-30 centimeters, for subsequent dicing. The dices are normally cubes with a side length of 0.5-1 centimeters, which is convenient for use in food preparation and other scenarios. Dicing can be done by mechanical dicer or by hand. Mechanical dicer is effective and can make certain uniform dices, which appropriates for large-scale manufacturing;

hands-on dicer can much better regulate the shape and top quality, yet is much less efficient. Blanching (optional) The primary purpose of paling celery is to suspend the enzymes that can create unwanted modifications in shade, flavor, and nutritional web content during the cold and storage process. Furthermore, paling assists to mellow out the raw flavor of celery, resulting in a more tasty and tender product. Procedure procedure. Place the diced celery right into boiling water for 1-2 minutes. Too long a time will cause the celery to soften exceedingly and shed a lot of nutrients; also short a time will certainly not accomplish the anticipated enzyme passivation impact. After blanching, promptly get rid of the celery cubes and cool them in cold water. This can quickly stop the warmth from reaching the celery dices, keeping them crisp and tender and with great color. Quick freezing. Precooling (optional).

Prior to quick freezing, the celery cubes can be precooled in a 0-5 ℃ environment. Precooling can decrease the temperature level of the celery cubes, minimize power consumption during fast cold, and help preserve the quality of the celery cubes and make ice crystals form even more evenly. Quick freezing process. Spread the pretreated celery cubes evenly on the conveyor belt of the quick freezing devices, such as a fluidized bed fast freezer or a spiral fast fridge freezer. The quick freezing temperature is generally managed at around -30 ℃ to -40 ℃. In such a low temperature atmosphere, the water in the celery dices can quickly develop fine ice crystals, decreasing damages to the cell structure. The quick freezing time varies depending upon the shapes and size of the celery cubes and the efficiency of the quick cold tools. Normally, the quick cold time for a cube of celery cubes with a side length of 0.5-1 cm might be around 10-15 mins. Packaging and storage space. Packaging. After fast freezing, packaging should be done as soon as possible to stop ice crystals on the surface of celery cubes from sublimating, which would certainly impact item high quality. Packaging materials can be plastic movie, aluminum foil bags or paper boxes. Usual product packaging methods include vacuum packaging and regular closed product packaging. Vacuum cleaner product packaging can better preserve the color, preference and nutrients of celery cubes and expand the service life; regular covered product packaging is fairly easy to run, yet the life span might be somewhat shorter. Storage space. Shop the packaged icy diced celery in a low-temperature cold storage below -18 ℃. At this temperature level, celery cubes can be stored for a long period of time, and the general shelf life can get to 12-24 months. Throughout storage, routinely inspect the temperature and humidity of the cold store to make certain that the ecological problems meet the demands and prevent item top quality destruction.
