Problems solved by technology

[0005] Because Majiagou celery has the characteristics of crisp root, tender stem, and sufficient water, it is easy to rot and deteriorate, resulting in a decline in taste quality, so its freshness period is short, generally only 2-3 days
Therefore, the storage and preservation of celery has always been a difficult problem. The method of controlled atmosphere and low temperature is adopted, but celery is very sensitive to low temperature, and it is prone to chilling injury in low temperature storage, resulting in a decline in quality, affecting its market sales and edible value. Research on improving storage methods

Abstract

The invention discloses a refrigeration method of high quality celery. The method is characterized by comprising the following steps: (1) precooling treatment of celery, (2) antistaling agent preparation, (3) precooling, (4) packaging by a food grade polyethylene film, and (5) stagewise cooling refrigeration storage. Through addition of the antistaling agent and stagewise cooling in storage, the celery can slowly adapt to the increasingly lower temperature and gradually reduce the sensitivity to low temperature, so as to greatly reduce the probability of chilling injury of the celery, keep the advantages of crisp roots, tender stems and sufficient moisture of the celery, maintain the taste and quality of celery, and extend the preservation time.

Description

technical field [0001] The invention belongs to the technical field of vegetable storage, and in particular relates to a refrigeration method for high-quality celery. Background technique [0002] Majiagou celery has tender yellow leaf stems, straight and hollow stems, large and tender trees, crisp fragrance, rich nutrition and high quality. Rich in calcium, iron, carotene, vitamin B1, vitamin B2, vitamin A, vitamin C and other essential elements for the human body, Dongmajiagou celery belongs to crude fiber vegetables, and contains celery oil, which has a unique aroma and can Appetizers promote appetite, and in medicine, it also has various health care functions such as clearing away heat and relieving coughs, invigorating the stomach, lowering blood pressure, detoxifying, and beautifying the skin. [0003] As one of the famous local specialties in Shandong Province, it is a national geographical indication product of China. Originally produced in Majiagou, Liyuan Subdist...
