Abstract

The invention discloses a cress processing method. The method comprises the following steps: 1, preprocessing: sterilizing picked cress in boiling water at normal pressure for 10-15min, and immersing the cress in sodium carbonate with the concentration of 0.03-0.08% for 30min according to a solid / liquid ratio of 1:10; 2, blanching and cooling: blanching the preprocessed cress in a Cu<2+> solution with the concentration of 200mg / kg at 85-95DEG C for 30min according to a solid / liquid ratio of 1:15, and cooling by flushing with circulating water for 30min; 3, carrying out acid solution immersion: immersing the cooled cress in an acetic acid solution with the pH value of 2.5 for 30min according to a solid / liquid ratio of 1:8; 4, carrying out calcium salt crispness maintenance: immersing the acetic acid immersed cress in a calcium chloride solution with the concentration of 0.2-0.3% for 20min according to a solid / liquid ratio of 1:10 to maintain the crispness; and 5, cleaning and draining: cleaning the processed cress with clear water, and draining. The cress processing method effectively maintains the green color of the cress, makes the processed cress have good mouth, and makes the eating standards of fresh cress basically reached.

Description

technical field [0001] The invention relates to the technical field of water celery processing, in particular to a processing method of water celery. Background technique [0002] Cress belongs to the family Apiaceae, genus Cress. Perennial aquatic perennial herb. Cress is also known as Shuiying, Xibenshan celery, cow grass, Chu Kui, knife celery, Shu celery, wild celery, etc. Water celery is now planted in many places, but the technology of water celery processing technology is not very mature, especially the technology of water celery keeping green and keeping crisp is not very mature. Contents of the invention [0003] Aiming at the above disadvantages, the present invention provides a water celery processing method, which effectively maintains the green color of the water celery and has a good taste, basically reaching the standard for eating fresh water celery. [0004] The technical scheme that the present invention solves its technical problem is: a kind of proce...
