Embodiment Construction

[0019] Such as figure 1 Shown, a kind of Gorgon fruit stem processing and fresh-keeping method of the present invention comprises the following process steps:

[0020] 1. Cleaning and removing impurities from raw materials: take 1000 kg of gorgon stems and wash them in a stainless steel cleaning pool with running water. Cleaning also requires the surface of gorgon stems to be clean;

[0021] 2. Pre-cooling: Cool the gorgon stems in cooling water at a temperature of 5-10°C to remove field heat and respiratory heat; raw materials that are too late for acceptance and processing can also be pre-cooled with cold water to prevent product discoloration;

[0022] 3. Peeling: manually or chemically peel the stems of Gorgon;

[0023] 4. Segmentation: According to product research, the Gorgon stem is segmented, and the length is generally 5-10cm;

[0024] 5. Color protection: use 1000-2000kg of 0.5-2.0% salt solution or 1000-2000kg of 0.05-0.5% citric acid solution to soak the gorgon s...

Abstract

The invention discloses a euryale ferox salisb stem processing and fresh-keeping method, which comprises the following steps of: after cleaning, impurity removal, peeling, section cutting and pre-cooling of the selected euryale ferox salisb stem raw material, soaking the euryale ferox salisb stems into 0.5 to 2.0 percent salt solution or 0.05 to 0.5 percent citric acid solution to protect color for 1 to 5 hours, hardening the color protected euryale ferox salisb stems for 0.5 to 2 hours in the solution containing 0.05 to 0.2 percent calcium chloride, 0.5 to 2 percent sodium dihydrogen phosphate and 0.1 to 0.2 percent citric acid, putting the hardened clean euryale ferox salisb stems into boiling water of 85 to 100 DEG C, blanching the euryale ferox salisb stems for 1 to 10 minutes, adding the solution containing 0. 1 to 0.2 percent calcium chloride and 0.1 to 0.5 percent citric acid into the blanching solution, performing further color protection and hardening treatment on the euryale ferox salisb stems, and then performing cooling, quick monomer freezing and quantitative packing. The fresh-keeping method has the advantages of simple process and low cost, keeps the original luster and taste of the euryale ferox salisb stems, and meets the requirements of natural green food.

Description

technical field [0001] The invention relates to the field of production and processing of health food, in particular to a method for processing and preserving gorgonian stems. Background technique [0002] Euryale ferox Salisb (Euryale ferox Salisb), also known as chicken head rice, is native to Southeast Asia. It is a large annual aquatic herb of the Nymphaeaceae family and is widely distributed in shallow lakes and swamps in the middle and lower reaches of the Yangtze River in my country. Euryale rice is rich in protein, fat, starch, and contains riboflavin, ascorbic acid, Ca, P, Fe and other elements; It has the effects of hearing and eyesight, prolonging life, and is a good dietary tonic. Gorgon fruit has been mentioned in the works of Zhang Zhongjing, a medical scientist in the Eastern Han Dynasty. Li Shizhen of the Ming Dynasty explained the name of Gorgon fruit in the thirty-third volume of the Fruit Department of "Compendium of Materia Medica", saying: Gorgon can he...
