Description

A kind of dehydration process of water celery

technical field

The invention relates to the technical field of food processing and preservation, in particular to a dehydration process of water celery.

Background technique

Water celery belongs to the Umbelliferae family, genus Water celery. Perennial aquatic perennial herb. Water celery is also known as Shuiying, Xibenshan celery, cow grass, knife celery, and Shu celery. The content of various vitamins and minerals in cress is relatively high. Every 100g of edible part contains 1.8g of protein, 0.24g of fat, 1.6g of carbohydrate, 1.0g of crude fiber, 160mg of calcium, 61mg of phosphorus, and 8.5mg of iron. Cress also contains rutin, watercresin and quercetin. Its tender stems and petioles are fresh and tender, fragrant and refreshing, and can be mixed raw or fried.

The pharmacological effects of cress are as follows: 1. Oral administration of cress volatile oil can excite the central nervous system, promote breathing, improve myocardial excitability, and strengthen blood circulation. Volatile oil, when used locally, can dilate blood vessels, promote circulation, and improve permeability; oral administration can promote gastric secretion, increase appetite, and has an expectorant effect. Phelpsin and phelvin-7-methyl ether have antihypertensive effect. 2. Water celery decoction can slow down the heart rate of the isolated frog heart, reduce the contractility of the myocardium, and reduce the cardiac output. It can resist arrhythmia in rats caused by barium chloride and aconitine, and resist the excitatory effect of adrenaline on the heart. 3. Cress extract has a certain protective effect on the liver of rats poisoned by carbon tetrachloride. 4. Cress decoction has obvious anti-yellowing effect on rat hepatitis formed by α-tea isothiocyanate, the content of serum bilirubin is significantly reduced, and the pathological changes of liver cell and bile duct epithelial degeneration and necrosis can be significantly alleviated. Cress injection also has obvious anti-jaundice effect on rats with carbon tetrachloride hepatitis, and has a significant anti-jamming effect.

Functions and indications of water celery: clearing away heat and diuresis. Control violent fever and polydipsia, jaundice, edema, gonorrhea, leukorrhea, scrofula, mumps. ①"The Classic": "The main woman is Chiwo.
