Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a Chinese toon storage, preservation and processing method. Background technique [0002] Chinese toon is rich in nutrients, and its leaves have a unique and strong taste, which is much more nutritious than other vegetables. Chinese toon is a famous seasonal product, containing volatile aromatic organic compounds such as toonin, which can invigorate the spleen and appetizer, and increase appetite. Nitrite levels are extremely low in fresh toon just off the tree, but once off the tree, nitrite levels continue to increase. Chinese toon must be polluted by microorganisms such as bacteria, mold, and yeast during picking, storage and transportation. Under certain conditions of temperature, humidity and oxygen, microorganisms will multiply, causing Chinese toon to rot and mildew quickly . Secondly, after being picked, Chinese toon will still carry out metabolic ac...
